Composed

When you look at Noble Energy, 
you see a leading independent energy 
company with a finely tuned portfolio of 
assets, a track record of success and a 
sound strategy for the future. 

But it’s what you don’t see 
that makes it that way.

Flexible
business model focused
on value creation

Stradivarius

The Stradivarius has long been recognized as the pinnacle of
the violin-maker’s art and craftsmanship, possessing a tonal range and
depth of sound unmatched by any other violin. These qualities have made
them sought after by the world’s virtuosos for over two centuries.

Beethoven

Composer and pianist
Ludwig van Beethoven’s contributions to
classical music are profound. His influence on the
development of the art form and its current interpretation
is timeless, bridging generations and cultures
to speak a universal language.

Best in class

exploration process delivering
 high-impact results

A  culture

dedicated to success and 
      strong business principles

Carnegie Hall

To perform onstage at Carnegie Hall is to have developed 
one’s abilities to their highest possible level, and it is there that each 
incandescent note lights the imagination of the audience.

 Innovative

 teams executing

 major projects

Harp

Intricate, delicate, yet surrounded
by strong, graceful structure, the harp produces
evocative tones of harmonic complexity. Each of its
nearly four dozen strings works in concert with
the others to create an ethereal sound that
has touched listeners for millennia.

 An inventory
of opportunities with 
significant running room

Flute

Though one of the symphony’s 
most common instruments, nothing 
about the flute is simple. Complex physics 
come into play to allow the instrument to 
possess a broad dynamic range, capable 
of soaring highs and a fluid depth 
of remarkable clarity.

 Experienced
 leadership guiding
 company strategy

Conducting

At the foundation of every symphony
is its conductor: driving the tempo, shaping
many sounds into one, and leading the ensemble
through a profusion of complex changes to
arrive at its destination as a diverse,
yet cohesive entity.

Letter to Shareholders

2009  was  a  year  of  many  challenges  –  for  the  global  economies,  our  nation  and  our  industry.  Our  country  began  the  year  in  the  middle
of  an  economic  crisis  with  no  certainty  as  to  when  we  would  see  improvement.  With  the  recession,  we  experienced  falling  demand  for
energy,  and  by  mid-January  2009  natural  gas  and  oil  prices  had  fallen  dramatically  from  July  1  of  the  prior  year.  Natural  gas  prices
continued to fall during the year reaching a low in early September that was 80 percent below what they were on July 1, 2008. Declining prices
meant significantly reduced cash flows. Capital investment in drilling programs was forced lower, leading to the U.S. rig count falling over 50 percent
over the same period.

Noble Energy entered 2009 well-prepared for this uncertain environment. Our balance sheet at the beginning of the year was strong, containing
approximately $1 billion in cash. Our debt-to-book-capital ratio, net of cash, was a low 15 percent. However, even with this financial strength, we took
early actions to better prepare Noble Energy. We initially reduced our 2009 capital program to approximately $1.6 billion from $2.3 billion in 2008
and later reduced it further to $1.4 billion. In addition, we successfully issued $1 billion in 10-year notes. These actions increased liquidity and gave
us greater flexibility. As the year progressed, the environment continued to improve. Crude oil prices rallied from the lows experienced earlier in the
year and helped to increase revenue and cash flow. Unfortunately, natural gas prices remained weak for most of the year. However, with approximately
50 percent of our U.S. gas production hedged, we significantly mitigated the effect of low gas prices.

The lower commodity prices significantly impacted financial results. We ended the year with a net loss of $131 million, although this loss included
approximately $600 million of before tax unrealized losses on commodity derivative instruments. In addition, there was another $600 million of
before tax asset impairments primarily related to U.S. properties that were sensitive to low natural gas prices and to our investments in Ecuador.
Capital expenditures for 2009 were carefully managed and ended the year at $1.3 billion. As a result, we were able to further strengthen our balance
sheet even in a challenging year with cash flow from operations totaling $1.5 billion, exceeding our capital spending. Production fell approximately
two and a half percent from what we averaged in 2008.

We added a total of 79 million barrels of oil equivalent (MMBoe) of proven reserves from drilling, acquisitions and performance revisions, which
represented 103 percent of 2009 production. These reserve additions were offset by negative revisions totaling 45 MMBoe due to price effects and
new rules governing how proven undeveloped reserves are booked. We expect that the negative reserve revisions will be reversed in future years as
prices return to more normal levels, and we execute our multi-year development programs.

Our strategy is to create organic growth through exploration and development while remaining an opportunistic acquirer of assets. The balance and
diversity of our portfolio continues to provide flexibility to better optimize the use of capital. Our key focus areas continue to be the U.S. onshore, the
deepwater Gulf of Mexico, the Eastern Mediterranean and West Africa. All four of these areas have strong bases of existing production as well as deep
inventories of investment opportunities. Because of the weak commodity environment, we chose to direct a sizable portion of our capital program
into longer-term investments in 2009. It was not justified to invest in natural gas production due to low prices, especially in the U.S.

Onshore in the U.S., we prioritized investments to areas where we could benefit from improving liquid prices. In our Northern Region, we continued
with  an  active  drilling  program  in  the  Wattenberg  field.  At  the  beginning  of  2010,  we  announced  that  we  had  entered  into  an  agreement  to
purchase  additional  assets  in  Wattenberg  and  the  surrounding  DJ  Basin.  This  acquisition,  which  closed  in  early  March  of  2010,  will  add  an
estimated 50 MMBoe of proven reserves and 10,000 barrels of oil equivalent per day of production. These assets contain several thousand drilling
opportunities and fit in very nicely with our existing operations. We expect to double the production from these properties over the next two years.
By the second half of 2010, we plan to have eight drilling rigs running in the Wattenberg field. Also onshore in the U.S. we continued an active

program in the Cleveland Sands development program in Western Oklahoma. This area benefits from liquid production which improves drilling
returns. Finally, in East Texas we formed a joint venture that allowed us to initiate drilling on our acreage located within the Haynesville shale
play. Our first well was completed and showed strong production results. We expect to maintain an active drilling program in the Haynesville
throughout 2010.

Our  exploration  program  continued  to  deliver  significant  new  resources  to  our  portfolio.  Over  the  past  three  years,  we  have  discovered  over
700 MMBoe of new resources, net to Noble Energy, through exploration. Most of these resources have not yet been recorded as proven reserves. In
2009, we made the largest discovery in our company’s history at Tamar offshore Israel. Following the drilling and testing of two wells at Tamar, we
announced that gross mean resources of the field were estimated to be approximately 6.3 trillion cubic feet of natural gas. Also in Israel in 2009, we
made a second discovery at Dalit. We expect to continue with a very active exploration program in 2010 - perhaps our largest exploration program
ever. We currently have seven significant wells scheduled for 2010 including five in the deepwater Gulf of Mexico, one in Equatorial Guinea and one
in the Eastern Mediterranean.

With a significant inventory of major exploration discoveries, we are quickly moving forward with plans for development. In 2009, we sanctioned
Aseng in Equatorial Guinea and Galapagos in the deepwater Gulf of Mexico. Following the Tamar discovery, we quickly began assembling a project
team charged with developing this huge discovery. By the end of the year, we announced two letters of intent (LOI) for gas sales from Tamar. Just
these first two LOI’s are expected to generate approximately $10 billion in gross sales revenues. Engineering and design work are moving forward
rapidly, and we currently expect to sanction the development of Tamar in 2010.

We continue to make significant progress with our other major discoveries. In Equatorial Guinea, engineering work on the liquid-rich Belinda
discovery has positioned us to potentially sanction this project in 2010. We are also evaluating additional projects that would ultimately allow us to
produce and sell the natural gas from our West Africa discoveries. In the deepwater Gulf of Mexico, we plan to drill one or two appraisal wells at our
Gunflint discovery. Gunflint was discovered in 2008 and represents our largest deepwater Gulf of Mexico exploration discovery to date.

The major exploration discoveries now under development are clearly positioning Noble Energy for significant future growth. Beginning in 2011 and
continuing through the middle of the decade, we expect to have new production coming on stream from major projects nearly every year. Galapagos
will be first in 2011 followed by Aseng and Tamar in 2012. Other major projects expected in the following years include Belinda, Diega and Carmen
in West Africa and Gunflint in the Gulf of Mexico. The execution of these major projects is having a significant impact on our organization. We
continue to recruit new employees who are experienced in designing and managing these technically challenging projects. We have formed a
major projects organization that will keep us focused on best-in-class processes in support of our project execution. Our goal is to combine our
best-in-class exploration results with best-in-class project execution in order to deliver maximum value to our shareholders.

It is more obvious than ever before that our success is dependent on the commitment and efforts of our employees. We continue to be successful in
attracting high-quality talent to Noble Energy. All of our employees have done an amazing job in delivering results in a very challenging year. We all
continue to focus on delivering superior returns to our shareholders while also assuring that the safety of everyone involved is preserved and impacts
on the environment are minimized. We remain committed to helping the communities in which we live as we carry out our business.

On behalf of the Board of Directors and all our employees, I want to thank all of our stakeholders for their continued confidence and support of
Noble Energy.

General 

Noble Energy, Inc. (Noble Energy, we or us) is a Delaware corporation, formed in 1969, that has been publicly traded 
on the New York Stock Exchange (NYSE) since 1980. We are an independent energy company that has been 
engaged in the acquisition, exploration, development, production and marketing of crude oil, natural gas, and natural 
gas liquids (NGLs) since 1932. In this report, unless otherwise indicated or where the context otherwise requires, 
information includes that of Noble Energy and its subsidiaries. We operate primarily in the Rocky Mountains, Mid-
continent, and deepwater Gulf of Mexico areas in the US, with key international operations offshore Israel and West 
Africa.   

Our aim is to achieve growth in earnings and cash flow through exploration success and the finding and development 
of a high quality portfolio of assets that is balanced between US and international projects. Exploration success, 
along with additional capital investment, in US and international locations such as Equatorial Guinea and Israel, have 
resulted in substantial growth in the last several years. In addition, occasional strategic acquisitions such as Patina 
Oil & Gas Corporation (Patina) in 2005 and U.S. Exploration Holdings, Inc. (U.S. Exploration) in 2006, combined with 
the sale of non-core assets, have allowed us to achieve a strategic objective of enhancing our asset portfolio, 
resulting in a company with assets and capabilities that include major US basins coupled with a significant portfolio of 
international properties. See Item 6. Selected Financial Data for additional financial and operating information for 
fiscal years 2005-2009. 

In the current commodity and economic environment, our focus has remained on positioning Noble Energy for the 
future. In January 2009, we announced a significant discovery at Tamar, offshore Israel, the largest discovery in our 
history. Also during 2009, we made substantial progress on our significant portfolio of long-term growth projects, 
including the sanctioning of the oil development projects at Aseng (formerly Benita) offshore Equatorial Guinea and at 
Isabela/Santa Cruz (which we refer to collectively as Galapagos) in the deepwater Gulf of Mexico, as well as making 
important progress on our plans for the Tamar discovery.  These and other major development projects typically offer 
long life, sustained cash flows after investment and attractive financial returns. We also have significant remaining 
exploration potential, primarily in the deepwater Gulf of Mexico and offshore West Africa and Israel.  

Major Development Project Inventory   Our exploration success has provided us with a number of significant 
development projects on which we are moving forward. These projects will require significant capital investments 
over the next several years.  Our major projects include the following: 

•  Galapagos (deepwater Gulf of Mexico); 

•  Aseng (offshore West Africa); 

• 

Tamar (offshore Israel); 

•  Gunflint (deepwater Gulf of Mexico); 

•  Belinda (offshore West Africa); and 

•  Diega / Carmen (offshore West Africa). 

These projects are discussed in more detail in the sections below. See also Item 7. Management’s Discussion and 
Analysis of Financial Condition and Results of Operations – Operating Outlook – Major Development Project 
Inventory.

 Natural gas is converted on the basis of six Mcf of gas per one barrel of oil equivalent. 

In December 2008, the Securities and Exchange Commission (SEC) announced that it had approved revisions to 
modernize its oil and gas company reserves reporting requirements. We adopted the new rules as of December 31, 
2009.  See Proved Reserves Disclosures, below, for additional disclosures provided in accordance with the SEC’s 
rules for Modernization of Oil and Gas Reporting and Item 8. Financial Statements and Supplementary Data – 
Supplemental Oil and Gas Information (Unaudited) for definitions of proved oil and gas reserves, proved developed 
oil and gas reserves and proved undeveloped oil and gas reserves. 

Crude Oil and Natural Gas Properties and Activities 

We search for crude oil and natural gas properties, seek to acquire exploration rights in areas of interest and conduct 
exploratory activities. These activities include geophysical and geological evaluation and exploratory drilling, where 
appropriate, on properties for which we have acquired exploration rights. Our properties consist primarily of interests 
in developed and undeveloped crude oil and natural gas leases and concessions. We also own natural gas 
processing plants and natural gas gathering and other crude oil and natural gas related pipeline systems which are 
primarily used in the processing and transportation of our crude oil, natural gas and NGL production. 

Exploration Activities   We primarily focus on organic growth from exploration and development drilling, 
concentrating on basins or plays where we have strategic competitive advantage and which we believe offer superior 
returns. We have had substantial exploration success in the deepwater Gulf of Mexico, West Africa and the Eastern 
Mediterranean resulting in a significant portfolio of major development projects. We have numerous exploration 
opportunities remaining in these areas and are engaged in new venture activity in other international locations as 
well.   

Appraisal, Development and Exploitation Activities   We assess our exploration successes for potential 
development as demonstrated in our growing inventory of major projects.  In 2009, we sanctioned the Isabela and 
Aseng projects and are progressing toward sanctioning the Tamar, Belinda and Gunflint projects during 2010 and/or 
2011.We support a significant portion of the capital needs of these major projects with our long-lived inventory of low-
risk development and exploitation projects.  Low-risk development and exploitation projects, such as the Wattenberg 
field in our North America operations, also provide diversification and balance to our worldwide portfolio.   

Acquisition and Divestiture Activities     We maintain an ongoing portfolio optimization program. Accordingly, we 
may engage in acquisitions of additional crude oil or natural gas properties and related assets through either direct 
acquisitions of the assets or acquisitions of entities owning the assets. We may also divest non-core assets in order 
to optimize our property portfolio. 

Pending Asset Acquisition   In January 2010, we announced that we have entered into a definitive agreement to 
acquire substantially all of the US Rocky Mountain assets of Petro-Canada Resources (USA) Inc. and Suncor Energy 
(Natural Gas) America Inc. for $494 million. We estimate total proved reserves to be 53 MMBoe, 45% of which are 
liquids and 80% are within the liquid-rich Wattenberg field, where our largest onshore US asset is located. The

acquisition will add approximately 10 MBoepd, or 46 MMcf of natural gas and 2.5 MBbls of liquids to our daily 
production base, starting from the closing date, for 2010 and will provide significant growth potential. Included in the 
purchase are 340,000 total net acres, nearly 200,000 of which are located in the Greater Denver-Julesberg (DJ) 
Basin. The acquisition is expected to close late in the first quarter 2010 and is subject to customary closing 
conditions. See United States - Northern Region discussion below.  

Mid-continent Acquisition   In 2008, we acquired producing properties in western Oklahoma for $292 million. 
Properties acquired cover approximately 15,500 net acres. The total purchase price was allocated to the proved and 
unproved properties acquired based on fair values at the acquisition date. Approximately $254 million was allocated 
to proved properties and $38 million to unproved properties. 

Sale of Argentina Assets   In 2008, we closed on the sale of our producing property interest in Argentina for a sales 
price of $117.5 million, effective July 1, 2007. The $24 million gain on sale was deferred until 2009 when approval 
was obtained from the Argentine government. Our crude oil reserves for Argentina totaled 7 MMBbls at December 
31, 2007. 

Sale of Gulf of Mexico Shelf Properties   In 2006, we sold all of our significant Gulf of Mexico shelf properties except 
for the Main Pass area, which required repairs related to hurricane damage at the time. As of the effective date of the 
sale, proved reserves for the Gulf of Mexico properties sold totaled approximately 7 MMBbls of crude oil and 110 Bcf 
of natural gas. The deepwater Gulf of Mexico remains a core area and is more aligned with our long-term business 
strategies.  

U.S. Exploration Acquisition   In 2006, we acquired U.S. Exploration, a privately held corporation, for $412 million plus 
liabilities assumed. U.S. Exploration’s reserves and production were located primarily in Colorado’s Wattenberg field. 
This acquisition significantly expanded our operations in one of our core areas. Proved reserves of U.S. Exploration 
at the time of acquisition were approximately 234 Bcfe, of which 38% were proved developed and 55% natural gas. 
Proved crude oil and natural gas properties were valued at $413 million and unproved properties were valued at 
$131 million. In addition, we recorded $34 million of goodwill.  

Patina Merger   In 2005, we acquired Patina through merger (Patina Merger) for a total purchase price of $4.9 billion. 
Patina’s long-lived crude oil and natural gas reserves provided a significant inventory of low-risk opportunities that 
balanced our portfolio. Patina’s proved reserves at the time of acquisition were estimated to be approximately 1.6 
Tcfe, of which 72% were proved developed and 67% natural gas. Proved crude oil and natural gas properties were 
valued at $2.6 billion and unproved properties were valued at $1.1 billion. In addition, we recorded $875 million of 
goodwill. 

United States 

We have been engaged in crude oil and natural gas exploration, exploitation and development activities throughout 
onshore US since 1932 and in the Gulf of Mexico since 1968. The Patina Merger and the acquisition of U.S. 
Exploration significantly increased the breadth of our onshore operations, especially in the Rocky Mountains and Mid-
continent areas. These two acquisitions, along with other acquisitions of producing and non-producing properties, 
have provided us with a multi-year inventory of exploitation and development opportunities. We expect to close on a 
purchase of additional US Rocky Mountain assets in first quarter 2010, which will further increase our operations and 
project inventory in this area. In 2009, we were awarded 22 new leases in the deepwater Gulf of Mexico.  

US operations accounted for 56% of our 2009 consolidated sales volumes and 56% of total proved reserves at 
December 31, 2009. Approximately 55% of the proved reserves are natural gas and 45% are crude oil, condensate 
and NGLs. Our onshore US portfolio at December 31, 2009 included 956,000 net developed acres and 1.3 million net 
undeveloped acres. We currently hold interests in 103 offshore blocks in the Gulf of Mexico.

Locations of our US onshore operations in the Wattenberg field, Mid-continent area and other significant areas are 
shown on the map below: 

Northern Region The Northern region consists of our operations in the Rocky Mountain area, which includes the DJ 
(Wattenberg field), Piceance, San Juan, and Wind River basins, as well as the Niobrara (Tri-State) and Bowdoin 
fields. The Rocky Mountain area is one of our core operating assets. The Northern region also includes the Mid-
continent area, consisting of properties in the Texas Panhandle, Oklahoma and Kansas.   

Wattenberg Field   The Wattenberg field (approximately 96% operated working interest), located in the DJ basin of 
north central Colorado, is our largest onshore US field and continues to grow. We acquired working interests in the 
Wattenberg field through the Patina Merger in 2005 and acquisition of U.S. Exploration in 2006. The Wattenberg field 
held 57% of our US proved reserves at December 31, 2009.  

One of the most attractive features of the field is the presence of multiple productive formations, which include the 
Codell, Niobrara, and J-Sand formations, as well as the D-Sand, Dakota and the shallower Shannon, Sussex and 
Parkman formations. Drilling in the Wattenberg field is considered lower risk from the perspective of finding crude oil 
and natural gas reserves.  

Our current field activities are focused primarily on the improved recovery of reserves through drilling new wells or 
deepening within existing wellbores, recompleting the Codell formation within existing J-Sand wells, refracturing or 
trifracturing existing Codell wells and refracturing or recompleting the Niobrara formation within existing Codell wells. 
A refracture consists of the restimulation of a producing formation within an existing wellbore to enhance production 
and add incremental reserves. A trifracture is effectively a refracture of a refracture. These projects and continued 
success with our production enhancement program, which includes well workovers, reactivations, and commingling of 
zones, allow us to increase production and add proved reserves to what is considered a mature field. 

Due to economic conditions, our 2009 program decreased from 2008 levels. In 2009, we drilled or participated in 424 
gross Wattenberg field development wells, with a 100% success rate. Three of these wells were horizontal wells 
targeting the Niobrara formation. We added approximately 36 MMBoe of proved reserves, approximately 49% of 
which were natural gas.  At year-end, we were running five drilling rigs and 17 completion units in the field. 

We have experienced significant growth in production from the Wattenberg field, from an average of 33 MBoepd at 
year-end 2005 to approximately 45 MBoepd for fourth quarter 2009. Expansion of field boundaries has resulted in a 
large increase in our crude oil and NGL stream since year-end 2005. As a result, year-end 2009 production included 
approximately 20 MBpd of liquids. Sales of Wattenberg field production accounted for 41% of total US sales volumes 
in 2009. 

The infrastructure in this area is improving and expanding. Oil transport alternatives improved in 2009 with the start 
up of a new interstate crude oil transportation pipeline system running from Weld County, Colorado, where the 

6 

 
 
 
 
 
Wattenberg field is located, to Cushing, Oklahoma. The pipeline, in which we own a small equity interest, provides 
another option for the marketing of our crude oil. We have a five-year throughput agreement with the pipeline. 

We continue to acquire acreage in the area and held interests in approximately 350,000 net acres at year-end 2009. 
We are planning an active capital program in 2010 and expect to increase the program from 2009 levels, drilling 
approximately 500 wells, with continued focus on new wells in the Codell/Niobrara formations. We will have the 
flexibility with short-term drilling rig contracts to decrease activity if economic conditions decline. Additionally, we have 
a substantial project inventory remaining and plan to continue steady refracture, trifracture, and recompletion 
programs in 2010. 

As discussed under Acquisition and Divestiture Activities – Pending Asset Acquisition above, we expect to close on 
an acquisition of additional US Rocky Mountain assets late in the first quarter 2010. We have identified several 
thousand projects associated with the assets being acquired, including over 2,000 Codell/Niobrara drilling locations in 
Wattenberg. We plan to add two rigs to our Wattenberg program in 2010 as a result of the transaction. We expect this 
activity to grow net production, with a focus on increasing liquids contribution. 

Mid-continent Area   The Mid-continent area includes properties in the Texas Panhandle, Oklahoma and Kansas. 
Significant areas of activity have been in the Cleveland Sandstone area of western Oklahoma (89% operated working 
interest). We drilled or participated in 31 development wells in 2009, 97% of which were successful.    

In 2009, we continued drilling in the Cleveland Sandstone formation in western Oklahoma, on acreage we acquired in 
2008. Cleveland Sandstone is a tight gas play characterized by low-permeability rock. We drilled 20 wells (included in 
the count above) using horizontal drilling techniques, all of which were successful, and recent wells have come on 
line with greater than 40% liquids production. We currently have one rig operating and expect to drill approximately 
the same number of wells in 2010 as we drilled in 2009.  

Other Northern Region   Other Northern region areas of activity are as follows: 

Piceance Basin – The Piceance basin in western Colorado (approximately 89% operated working interest) is a major 
North America natural gas basin and is characterized by low-porosity rock. The primary productive formation is the 
Mesaverde Williams Fork formation.  Multiple wells are drilled from individual drilling pads to reduce rig mobilization 
costs in mountainous terrain and to minimize environmental impact on the surface area.  Well spacing is 
approximately ten acres per well. 

As in the Wattenberg field, Piceance basin drilling time per well has been reduced due to our increased use of 
improved drilling technology. In the Piceance basin, we are using new fit-for-purpose rigs which include design 
innovations and technology improvements that capture incremental time savings during all phases of the well drilling 
process, including moving between wells. Fit-for-purpose rigs can drill multiple wells from one location and are 
particularly useful in developing hydrocarbon reserves in tight-gas areas such as the Piceance basin.  

In 2009, we drilled or participated in 48 development wells and one exploratory well, 100% of which were successful. 
Successful drilling activity in recent years has led to significant volume growth; production has grown from 2 MMcfepd 
in 2005 to 54 MMcfepd for fourth quarter 2009. 

We have assembled a significant acreage position in the Piceance basin and currently hold interests in approximately 
20,000 net acres providing a large inventory of future projects. At this time, we plan to operate a single-rig drilling 
program in 2010.  

Tri-State Area (Niobrara) – Our operations in the Tri-State area (eastern Colorado, extending into Kansas and 
Nebraska) center primarily around the development of the Niobrara Trend (approximately 96% operated working 
interest). The Niobrara formation is an important shallow natural gas producer. Since 2006, we have expanded our 
acreage position to over 580,000 net acres.  We have a substantial future project inventory, including Niobrara infill 
and exploitation drilling along with gathering system and compressor station additions to develop reserves and deliver 
new production.  In 2009, we drilled or participated in 64 development wells, 100% of which were successful, and we 
plan to continue our Niobrara drilling program in 2010. 

Wind River Basin –  At Iron Horse in the Wind River Basin (88% operated working interest) located in central 
Wyoming, we drilled 18 development wells during 2009 with a 94% success rate.  We plan to continue our drilling 
program here during 2010 and expect to drill approximately 20 new wells.  

Bowdoin and San Juan – We are also active in the Bowdoin field (approximately 63% operated working interest), 
located in north central Montana and the San Juan basin (approximately 82% operated working interest), located in 
northwestern New Mexico and southwestern Colorado. In 2009, activity was reduced in these areas as we focused 
most of our capital spending on the core development fields of Wattenberg, Piceance and western Oklahoma. We 
drilled or participated in a total of 13 development wells in the Bowdoin field and San Juan basin, 100% of which were 
successful, and one unsuccessful exploratory well. 

Southern Region   The Southern region includes the deepwater Gulf of Mexico and onshore areas primarily in Texas 
and Louisiana.  

Deepwater Gulf of Mexico   The deepwater Gulf of Mexico is one of our core areas and accounted for 19% of 2009 
US sales volumes and 7% of US proved reserves at December 31, 2009. We currently hold leases on 103 deepwater 

7 

 
Gulf of Mexico blocks, representing approximately 390,000 net acres. We operate approximately 86% of the leases. 
Locations of our deepwater Gulf of Mexico developments are shown on the map below: 

We continue to expand our deepwater Gulf of Mexico operations primarily through an active exploration program, 
expansion of our 3-D seismic database, and lease acquisition. Our exploration activities have led to discoveries at 
Gunflint, a 2008 discovery which is our largest deepwater Gulf of Mexico discovery to date; Isabela; Redrock/Raton; 
and, most recently, Santa Cruz.   

During 2009, we moved forward with development plans for some of our recent discoveries, as discussed below, and 
continued our exploratory program. We participated in Central Gulf of Mexico Lease Sale 208 and were awarded 22 
new deepwater Gulf of Mexico blocks which will complement our growing inventory of exploration opportunities. We 
currently have an inventory of over 30 identified prospects, with a combination of both large stand-alone prospects as 
well as a number of smaller, tie-back opportunities.   

Our exploration efforts continued during December 2009 as drilling began on two significant test wells at the Deep 
Blue prospect (Green Canyon Block 723; 33.75% operated working interest) and one at the Double Mountain 
prospect (Green Canyon Block 556; 30% non-operated working interest). 

Our most significant deepwater Gulf of Mexico properties and current development plans are discussed in more detail 
below: 

Gunflint (Mississippi Canyon Block 948; 37.5% operated working interest and Mississippi Canyon Block 949; 43.75% 
operated working interest)   We announced the Gunflint crude oil discovery, our largest deepwater Gulf of Mexico 
discovery to date, in October 2008. We have acquired additional seismic information and are preparing to drill one or 
two appraisal wells in 2010. We are the operator of the development. 

Galapagos Development Project including Isabela (Mississippi Canyon Block 562, 33% non-operated working 
interest) and Santa Cruz (Mississippi Canyon Blocks 519/563, 23.25% operated working interest)  During third 
quarter 2009, we approved the Galapagos development project, which consists of our 2007 discovery, Isabela, and 
our 2009 discovery on adjacent acreage, Santa Cruz. The phased development plan includes completion of the 
Isabela and Santa Cruz wells during second and third quarter 2010, and then connecting them to nearby 
infrastructure via subsea tiebacks.   Initial production is expected in 2011.  During the first half of 2010, we also plan 
to drill the Santiago exploration well (23.25% operated working interest) which is a separate prospect in the same 
offshore block as Santa Cruz.  If the Santiago well is successful, it will be completed in 2010, with production 
expected in 2011.   

Redrock/Raton (Mississippi Canyon Blocks 204, 248 and 292; 66.67 % working interest)   Redrock was a 2006 
natural gas/condensate discovery and Raton was a 2006 natural gas discovery. The South Raton appraisal well was 
also drilled in 2006.  In 2007, we successfully sidetracked and completed the Raton discovery well and it was tied 

8 

 
 
 
 
back and came on production in late 2008. In 2008, we drilled a successful sidetrack-appraisal well at South Raton 
and we currently expect it to be tied back to a host facility. Redrock is currently considered a co-development 
candidate to the completed sidetrack well at South Raton. We are the operator of Redrock/Raton. 

Swordfish (Viosca Knoll Blocks 917, 961 and 962; 85% working interest)   Swordfish was a 2001 discovery and 
began producing in 2005. During 2009, a Swordfish gas well watered out. We sidetracked the well into an oil zone, 
and production began in January, 2010. The Swordfish project currently includes three producing wells connected to 
a third-party production facility through subea tiebacks. We are the operator of Swordfish.  

Ticonderoga (Green Canyon block 768; 50% working interest)   Ticonderoga is a non-operated 2004 crude oil 
discovery and began producing in 2006. The project currently includes three producing wells connected to existing 
infrastructure through subea tiebacks. In September 2008, Ticonderoga was shut-in as a result of hurricane damage 
to third-party processing and pipeline facilities. It remained shut-in until August 2009 when it was returned to full 
production. 

Onshore East Texas and North Louisiana   This is an emerging area for us. Recent acquisitions have increased our 
leasehold acreage to approximately 17,000 gross acres. Our 2009 drilling program targeted the Haynesville shale 
(approximately 60% working interest), and we completed our first horizontal East Texas Haynesville shale well with 
an initial thirty-day average production rate of over 11 MMcfpd, gross. We drilled a second exploration well in fourth 
quarter 2009 that was completed in late January 2010 and is being tested. We plan to drill approximately 10 to 11 
Haynesville wells on our operated acreage in 2010 and participate in another seven to eight Haynesville wells 
operated by others. 

International 

International operations are significant to our business, accounting for 44% of consolidated sales volumes in 2009 
and 44% of total proved reserves at December 31, 2009. International proved reserves are approximately 64% 
natural gas and 36% crude oil. Operations in Equatorial Guinea, Ecuador, China and Suriname are conducted in 
accordance with the terms of production sharing contracts. In Cameroon, we operate in accordance with the terms of

Locations of our major international operations are shown on the map below: 

West Africa (Equatorial Guinea and Cameroon)   West Africa is one of our core operating areas. Crude oil and 
natural gas sales volumes accounted for 61% of 2009 consolidated international sales volumes and 70% of 
international proved reserves at December 31, 2009. At December 31, 2009, we held approximately 53,000 net 
developed acres and 212,000 net undeveloped acres in Equatorial Guinea and 563,000 net undeveloped acres in 
Cameroon.   

Alba Field   We began investing in West Africa in the early 1990’s. Activities center around our 34% non-operated 
working interest in the Alba field, offshore Equatorial Guinea, which is one of our most significant assets. Operations 
include the Alba field and related production and condensate facilities, a methanol plant, and an onshore LPG 
processing plant (both located on Bioko Island) where additional condensate is produced. The methanol plant is 
capable of producing up to 3,000 MTpd gross. 

We sell our share of natural gas production from the Alba field to the LPG plant, the methanol plant and an 
unaffiliated LNG plant. The LPG plant is owned by Alba Plant LLC (Alba Plant), in which we have a 28% interest 
accounted for by the equity method. The methanol plant is owned by Atlantic Methanol Production Company, LLC 
(AMPCO), in which we have a 45% interest accounted for by the equity method. The methanol plant purchases 
natural gas from the Alba field under a contract that runs through 2026. AMPCO subsequently markets the produced 
methanol to customers in the US and Europe. Alba Plant sells its LPG products and condensate at our marine 
terminal at prevailing market prices. We sell our share of condensate produced in the Alba field and from the LPG 
plant under short-term contracts at market-based prices.  

Blocks O and I, YoYo and Tilapia    During the past several years, we have conducted a successful exploration and 
appraisal drilling program in the Douala basin in West Africa, centering around Blocks O and I, offshore Equatorial 
Guinea, and the YoYo mining concession and Tilapia production sharing contract offshore Cameroon, where we have 
an interest in over 1.1 million gross acres. We are the operator in Cameroon (50% working interest) and the technical 
operator on Block O (45% working interest) and Block I (40% working interest).  

Our first discovery occurred in October 2005, when we announced successful test results from the O-1 (Belinda) 
exploration well offshore Equatorial Guinea. In 2007, we drilled seven wells, resulting in three new discoveries and 
three successful appraisal wells. In 2008, we announced successful results from the I-5 Benita oil appraisal well on 
Block I; the Felicita, a condensate and natural gas discovery on Block O; and the Diega, a gas condensate and oil 
discovery on Block I.  In February 2009, we announced a successful oil discovery on Block O at the Carmen 
prospect.   

In December 2008, we submitted a Plan of Development for the Aseng field (formerly known as Benita) to the 
government of Equatorial Guinea. On July 22, 2009, we announced that it had been sanctioned by us, our partners, 
and the Ministry of Mines, Industry, and Energy of the Republic of Equatorial Guinea.   

Initial development of the Aseng field will include multiple subsea wells flowing to a floating production, storage and 
offloading vessel (FPSO) where the production stream will be separated.  The oil will be stored on the FPSO until 
sold, while the natural gas and water will be reinjected into the reservoir to maintain pressure and maximize oil 
recoveries. The FPSO is designed with capacity to process 120 MBpd of liquids, including 80 MBpd of oil. In addition, 
the vessel will be capable of reinjecting 170 MMcfpd of natural gas. Storage on the vessel will be approximately 1.6 
MMBbls of liquids. The vessel is designed to act as an oil production hub, and as a liquids storage and offloading hub 
with capabilities to support future subsea oil field developments, and capabilities to take on board, independently from 
the production train, stabilized condensate from gas condensate fields in the area. First production from the Aseng 
field is estimated to commence by mid-year 2012 at 50 MBpd of oil gross (16.5 MBpd net). The FPSO and subsea 

10 

 
 
 
equipment contracts were awarded in 2009, and construction activities have begun on the FPSO. We have two rigs 
contracted to assist in field development. Drilling and completion activities have commenced.     
We have evaluated the potential for additional liquids and gas projects, and expect that the next development will be 
at the Belinda field. We are engaged in geologic and reservoir FEED (front end engineering design) work at Belinda, 
targeting liquid production from this gas condensate field.  We currently anticipate drilling subsea wells which will be 
tied to a production facility that would remove liquids and reinject gas for future use pending further development at 
Belinda.  The liquids would be transported to the FPSO at Aseng for storage and sales.  Belinda project sanction is 
currently scheduled to occur in 2010 with production beginning in 2013. We are also evaluating future oil projects at 
Diega and Carmen and currently scheduling first production for 2014. 

In 2010, we expect to resume exploration activities offshore Equatorial Guinea and acquire a 3-D seismic survey over 
YoYo and portions of Tilapia in Cameroon. 

Eastern Mediterranean (Israel and Cyprus)   Another core operating area is located offshore Israel. Natural gas 
sales volumes in Israel accounted for 21% of 2009 consolidated international sales volumes and natural gas reserves 
accounted for 11% of international proved reserves at December 31, 2009. At December 31, 2009, we held 
approximately 29,000 net developed acres and 796,000 net undeveloped acres located between 10 and 90 miles 
offshore Israel in water depths ranging from 700 feet to 6,500 feet. Our leasehold position in Israel includes four 
leases and 17 licenses.  We are the operator of the properties. We also hold a license covering approximately 
795,000 net undeveloped acres offshore Cyprus. 

Mari-B Field    We have been operating in the Mediterranean Sea, offshore Israel, since 1998, and the Mari-B field 
(47% working interest) is one of our core international assets. The Mari-B field is the first offshore natural gas 
production facility in Israel and currently has a peak deliverability of approximately 500 MMcfpd from five wells. In 
2008, we commissioned a permanent onshore receiving terminal in Ashdod for distribution of natural gas from the 
Mari-B field to purchasers. During 2009, we moved forward on a compression project that we expect will recover 
additional reserves and extend the field’s peak deliverability. We also began mobilizing equipment to drill two 
development wells planned in the first half of 2010. Together with the completion of the compression work, these new 
wells will provide substantial, additional near-term gas deliverability and serve as injection wells for natural gas 
storage in the future. 

Natural gas sales began in 2004 and have increased steadily as Israel’s natural gas infrastructure has developed. 
Average sales volumes have risen from 48 MMcfpd in 2004 to a record high of 139 MMcfpd in 2008 and were 114 
MMcfpd in 2009. The natural gas market in Israel continues to be robust. The Israel Electric Corporation Limited 
(IEC), our largest purchaser, has continued to convert power plants to use natural gas as fuel. In 2009, the IEC power 
plant at Hagit began consuming natural gas purchased from us and in December 2009 we initiated natural gas sales 
to a new customer, Israel Chemicals Ltd. 

During third quarter 2009, we signed a new natural gas sales contract with our primary customer, IEC, under the 
terms of which they will purchase the majority of our remaining undedicated Mari-B field gas at prices expected to be 
significantly higher than what we have been receiving under the original contract. The actual price received is tied to 
a blend of liquids prices and a producer price index.  In addition, it was agreed that all sales from the Mari-B field 
going forward will be proportionately allocated between the two contracts regardless of the total volume sold. This is a 
major change from the past arrangement wherein only “excess” volumes above a threshold level received premium 
prices.  In addition, we have signed a letter of intent (LOI) with IEC, under which IEC expects to purchase natural gas 
to establish a strategic inventory reserve at Mari-B. The Mari-B partners would provide IEC with injection, storage and 
withdrawal capabilities for this inventory under a related service agreement.  

Competing imports of natural gas from Egypt to Israel began in 2008. However, there is still opportunity for significant 
new sales in the future as the Israeli infrastructure and markets continue to expand.  

Tamar and Dalit   During 2009, our exploratory program resulted in two significant discoveries. In January 2009, we 
announced a very significant natural gas discovery at the Tamar-1 well at the Tamar prospect (36% working interest), 
offshore northern Israel, and in February 2009, we announced a successful test of production flow rates at the 
location. Then in March 2009, we announced another natural gas discovery at the Dalit prospect (36% working 
interest) followed by a successful well test in April 2009.  

We then drilled a Tamar appraisal well (Tamar-2), the results of which increased our estimate of the size of the 
reservoir and confirmed its high quality and extent. Tamar is the largest discovery in our history.  

We are moving forward with Tamar development plans, and expect project sanction and recording of proved reserves 
in the first half of 2010, with first production projected for 2012.   

In fourth quarter 2009, we signed an LOI to sell natural gas from the Tamar field to Dalia Power Energies (Dalia). 
Dalia, a privately-owned electricity company, has a license to build a natural gas-fired power plant in Israel with 
operations planned to commence in 2013. According to terms of the LOI, we and our partners will deliver natural gas 
volumes of approximately 200 Bcf to Dalia under a 17-year supply agreement. Sales volumes under the LOI may be 
increased to 700 Bcf depending upon the final size of the power plant and extent of operations. We also signed an 
LOI to sell natural gas from the Tamar field to IEC. IEC expects to purchase at least 95 Bcf of natural gas per year 
with the potential to procure significantly higher quantities for a period of 15 years beginning at the startup of Tamar.  

11 

 
We continue to remain focused on the vast exploration potential remaining offshore Israel. The successes at Tamar 
and Dalit opened up a substantial new natural gas basin, the Levantine.  A 3-D seismic program is underway to 
collect additional data over several leads on our acreage in the Levantine. Based on results from the seismic 
program, we are planning to drill an exploratory well in the area in the second half of 2010. 

Other 

North Sea   We have been conducting business in the North Sea (the Netherlands and the UK) since 1996 and 
currently have working interests in 18 licenses with working interests ranging from 7% to 40%. We are the operator of 
one block.  The North Sea accounted for 8% of 2009 consolidated international sales volumes and 7% of 
international proved reserves at December 31, 2009. At December 31, 2009, we held approximately 6,000 net 
developed acres and 44,000 net undeveloped acres. 

Most of our production is from the non-operated Dumbarton field (30% working interest) in blocks 15/20a and 15/20b 
in the UK sector of the North Sea. We also produce from the MacCulloch, Hanze, Cook and other fields. 

The Dumbarton development, which began production in 2007, includes a subsea tie-back to the GP III, an FPSO in 
which we own a 30% interest. Additional development (30% working interest) began in 2008, and two new wells were 
brought on line.  During 2009, our field optimization work continued.  Dumbarton now has eight horizontal producers 
and two water injection wells.   

The Dumbarton field experienced a controlled shut-down in August 2009, due to a malfunctioning swivel on the 
FPSO. Production was deferred for essentially all of September and October.    

We also participated in the development of the nearby Lochranza discovery in block 15/20a (30% working interest). 
During 2009, the first Lochranza horizontal well was completed and tied back to Dumbarton’s subsea facilities. 
Production began in fourth quarter 2009.  We expect a second horizontal well to be completed and come on line in 
the first quarter of 2010. 

We have also participated in the Flyndre project (22.5% working interest) and Selkirk project (30.5% working 
interest), both located in the UK sector of the North Sea. At Flyndre, we successfully completed an exploratory 
appraisal well in 2007.  We are currently working with the project operator and other partners to finalize the field 
development plan and relevant operating agreements. At Selkirk, we participated in the drilling of an appraisal well 
which was sidetracked to the original discovery well location, to ensure presence of effective reservoir, and 
suspended as a future producer. We are currently working with our partners on development options. 

In 2009, we conducted a market test of our wholly-owned subsidiary Noble Energy (Europe) Limited, which holds our 
interests in the Netherlands and the UK, and received bids. However, we have not committed to a plan to sell these 
assets. 

Ecuador   Operations in Ecuador accounted for 5% of 2009 consolidated international sales volumes and 8% of 
international proved reserves at December 31, 2009. The concession covers approximately 12,000 net developed 
acres and 849,000 net undeveloped acres. 

We have been operating in Ecuador since 1996. We utilize natural gas from the Amistad field (in shallow water 
offshore Ecuador) to generate electricity through a 100%-owned natural gas-fired power plant, located near the city of 
Machala. The Machala power plant, which began operating in 2002, is a single cycle generator with a capacity of 130 
MW from twin turbines. It is the only natural gas-fired commercial power generator in Ecuador and currently one of 
the lowest cost producers of thermal power in the country. The Machala power plant connects to the Amistad field via 
a 40-mile pipeline. In 2009, power generation totaled 902 GW hours. 

See Risk Factors – Our operations and investment in Ecuador may be adversely affected by the country's unsettled 
economic and political environment  and Item 7. Management’s Discussion and Analysis of Financial Condition and 
Results of Operations – Current Conditions in Ecuador. 

China     We have been engaged in exploration and development activities in China since 1996, with production 
beginning in 2003. We have a 57% working interest in the Cheng Dao Xi (CDX) field, which is located in the shallow 
water of the southern Bohai Bay. During fourth quarter 2009, we drilled one horizontal well from our existing platform 
at the CDX field and commenced drilling a second well.  The rig will initiate a program to pre-drill a number of 
production and injection wells designed to be connected to a second platform at the field.  This is part of the ongoing 
expansion project with plans to install the second platform and connect the additional wells in late 2010. China 
accounted for 5% of 2009 consolidated international sales volumes and 4% of international proved reserves at 
December 31, 2009. At December 31, 2009, we held approximately 4,000 net developed acres and no undeveloped 
acres.  

Additional International Locations   We hold approximately four million net undeveloped acres in other international 
locations including Suriname, Nicaragua, and India.

Proved Reserves Disclosures 

Recent SEC Rule-Making Activity   In December 2008, the SEC announced that it had approved revisions 
designed to modernize the oil and gas company reserves reporting requirements. The most significant amendments 
to the requirements included the following: 

•  Commodity Prices – Economic producibility of reserves and discounted cash flows are now based on a 12-

month average commodity price unless contractual arrangements designate the price to be used.   
•  Disclosure of Unproved Reserves – Probable and possible reserves may be disclosed separately on a 

voluntary basis. 

•  Proved Undeveloped Reserves Guidelines – Reserves may be classified as proved undeveloped if there is a 
high degree of confidence that the quantities will be recovered and they are scheduled to be drilled within 
the next five years, unless the specific circumstances justify a longer time.  

•  Reserves Estimation Using New Technologies – Reserves may be estimated through the use of reliable 

technology in addition to flow tests and production history. 

•  Reserves Personnel and Estimation Process – Additional disclosure is required regarding the qualifications 
of the chief technical person who oversees the reserves estimation process.  We are also required to 
provide a general discussion of our internal controls used to assure the objectivity of the reserves estimate. 
•  Disclosure by Geographic Area – Reserves in foreign countries or continents must be presented separately 

if they represent more than 15% of our total oil and gas proved reserves. 

•  Non-Traditional Resources – The definition of oil and gas producing activities has expanded and focuses on 

the marketable product rather than the method of extraction. 

We adopted the rules effective December 31, 2009.  

Effect of Adoption    Application of the new reserve rules resulted in the use of lower prices at December 31, 2009 for 
both oil and gas than would have resulted under the previous rules. Use of new 12-month average pricing rules at 
December 31, 2009 resulted in a decrease in proved reserves of approximately 27 MMBoe. Use of the old year-end 
prices rules would have resulted in an increase in proved reserves of approximately 34 MMBoe at December 31, 
2009.  Therefore, the total impact of the new price methodology rules resulted in negative reserves revisions of 61 
MMBoe.  In addition to the new pricing methodology rules, the new proved undeveloped reserves rules, which limit 
PUDs to those scheduled to be drilled within the next five years, resulted in an additional reduction of proved 
reserves of approximately 18 MMBoe.  

Internal Controls Over Reserves Estimates    Our policies regarding internal controls over the recording of 
reserves estimates requires reserves to be in compliance with the SEC definitions and guidance and prepared in 
accordance with generally accepted petroleum engineering principles. Responsibility for compliance in reserves 
bookings is delegated to our Corporate Reservoir Engineering group and requires that reserves estimates be made 
by the regional reservoir engineering staff and reviewed by the regional reservoir engineering supervisor. 

Qualified petroleum engineers in our Houston, Denver and London offices prepare all reserves estimates for our 
different geographical regions. These reserves estimates are reviewed and approved by regional management and 
senior engineering staff with final approval by the Vice President – Strategic Planning, Environmental Analysis & 
Reserves (Vice President – Reserves) and certain members of senior management.  

Our Vice President – Reserves is the technical person primarily responsible for overseeing the preparation of our 
reserves estimates. Our Vice President – Reserves has a Bachelor of Science degree in Engineering and over 20 
years of industry experience with positions of increasing responsibility in engineering and evaluations. The Vice 
President – Reserves reports directly to our Chief Executive Officer. 

We engage a third-party petroleum consulting firm to audit a significant portion of our reserves.  See Third-Party 
Reserves Audit below. 

Technologies Used in Reserves Estimation   The SEC’s new rules expanded the technologies that a company can 
use to establish reserves. The SEC now allows use of techniques that have been proved effective by actual 
production from projects in the same reservoir or an analogous reservoir or by other evidence using reliable 
technology that establishes reasonable certainty.  Reliable technology is a grouping of one or more technologies 
(including computational methods) that has been field tested and has been demonstrated to provide reasonably 
certain results with consistency and repeatability in the formation being evaluated or in an analogous formation.  

We used a combination of production and pressure performance, wireline wellbore measurements, simulation 
studies, offset analogies, seismic data and interpretation, wireline formation tests, geophysical logs and core data to 
calculate our reserves estimates, including the material additions to the 2009 reserves estimates. 

Third-Party Reserves Audit   In each of the years 2009, 2008 and 2007, we retained Netherland, Sewell & 
Associates, Inc. (NSAI), independent, third-party reserves engineers, to perform reserves audits of proved reserves. 
The reserves audit for 2009 included a detailed review of 20 of our major international, deepwater Gulf of Mexico and 
US onshore fields, which covered approximately 78% of US proved reserves and 96% of international proved 
reserves (86% of total proved reserves). The reserves audit for 2008 included a detailed review of 18 of our major 
fields and covered approximately 86% of total proved reserves. The reserves audit for 2007 included a detailed 
review of 16 of our major fields and covered approximately 81% of total proved reserves.   

13 

 
In connection with the 2009 reserves audit, NSAI prepared its own estimates of our proved reserves. In order to 
prepare its estimates of proved reserves, NSAI examined our estimates with respect to reserves quantities, future 
producing rates, future net revenue, and the present value of such future net revenue. NSAI also examined our 
estimates with respect to reserves categorization, using the definitions for proved reserves set forth in the recently 
updated Regulation S-X Rule 4-10(a) and subsequent SEC staff interpretations and guidance. In the conduct of the 
reserves audit, NSAI did not independently verify the accuracy and completeness of information and data furnished 
by us with respect to ownership interests, oil and gas production, well test data, historical costs of operation and 
development, product prices, or any agreements relating to current and future operations of the fields and sales of 
production. However, if in the course of the examination something came to the attention of NSAI which brought into 
question the validity or sufficiency of any such information or data, NSAI did not rely on such information or data until 
it had satisfactorily resolved its questions relating thereto or had independently verified such information or data. 
NSAI determined that our estimates of reserves conform to the guidelines of the SEC, including the criteria of 
“reasonable certainty,” as it pertains to expectations about the recoverability of reserves in future years, under 
existing economic and operating conditions, consistent with the definition in Rule 4-10(a)(2) of Regulation S-X. NSAI 
issued an unqualified audit opinion on our proved reserves at December 31, 2009, based upon its evaluation. The 
NSAI opinion concluded that our estimates of proved reserves were, in the aggregate, reasonable and have been 
prepared in accordance with generally accepted petroleum engineering and evaluation principles. NSAI’s report is 
attached as Exhibit 99.2 to this Annual Report on Form 10-K. 

The fields audited by NSAI are chosen in accordance with company guidelines and result in the audit of a minimum of 
80% of our total proved reserves. The fields are chosen by the Vice President – Reserves and are reviewed by senior 
management and the Board of Directors.  When compared on a field-by-field basis, some of our estimates are 
greater and some are less than the estimates of NSAI. Given the inherent uncertainties and judgments that go into 
estimating proved reserves, differences between internal and external estimates are to be expected. On a quantity 
basis, the NSAI field estimates ranged from one MMBoe above to 16 MMBoe below as compared with our estimates. 
On a percentage basis, the NSAI field estimates ranged from 9% above our estimates to 20% below our estimates. 
Differences between our estimates and those of NSAI are reviewed for accuracy but are not further analyzed unless 
the aggregate variance is greater than 10%. Reserves differences at December 31, 2009 were, in the aggregate, 
approximately 21 MMBoe, or 3%. 

Proved Undeveloped Reserves (PUDs)   As of December 31, 2009, our PUDs totaled 142 MMBbls of crude oil and 
769 Bcf of natural gas, for a total of 270 MMBoe.   

PUD Locations     Approximately 70% of our PUDs at year-end 2009 were associated with our major development 
areas in the Wattenberg field (onshore US) and the Alba field (offshore Equatorial Guinea). An additional 17% of 
PUDs at year-end 2009 were associated with major development projects at the Aseng field (offshore Equatorial 
Guinea) and the Galapagos project (deepwater Gulf of Mexico). All of these projects will have PUDs convert from 
undeveloped to developed as these projects begin production and/or production facilities are expanded or upgraded. 

Changes in PUDS    Changes in PUDs that occurred during the year were due to: 

•   conversion of approximately 23 MMBoe PUDs into proved developed reserves;  
•  reclassification of approximately 18 MMBoe PUDs that were not scheduled to be developed within five years 

from proved to probable reserves; and 

•  negative revisions of approximately 23 MMBoe in PUDs due to changes in commodity prices. 

The majority of the reserves reclassified from proved reserves to probable reserves were associated with the 
Wattenberg field, where we maintain an extensive multi-year development program.  

Development Costs    Costs incurred relating to the development of PUDs were approximately $440 million in 2009, 
$528 million in 2008 and $390 million in 2007.  

Estimated future development costs relating to the development of PUDs are projected to be approximately $900 
million in 2010, $800 million in 2011, and $500 million in 2012. 

Drilling Plans    All PUD drilling locations are scheduled to be drilled prior to the end of 2014.  PUDs associated with 
projects other than drilling (such as compression projects) are also expected to be converted to proved developed 
reserves prior to the end of 2014.  Initial production from these PUDs is expected to begin between 2010 to 2015. 

We have 7 MMBoe of PUDs associated with an international discovery that has been booked for longer than five 
years.  Development planning is proceeding on this project, and drilling is expected to begin in the next two years.  
The only other PUDs that have been booked for longer than five years are associated with compression projects.  In 
those cases, the reserves are expected to be recovered from existing wells.

and $1.12 per Mcf (2007) from hedging activities. The effect of hedging activities on the average realized natural 
gas price for 2009 was de minimis. 

(3)  Average crude oil sales prices reflect reductions of $5.57 per Bbl (2009), $7.59 per Bbl (2008), and $2.19 per Bbl 
(2007) from hedging activities.  Natural gas is under contract for $0.25 per MMBtu to a methanol plant, an LPG 
plant and an LNG plant. Sales to these plants are based on a BTU equivalent and then converted to a dry gas 
equivalent volume. The methanol and LPG plants are owned by affiliated entities accounted for under the equity 
method of accounting. The volumes produced by the LPG plant are included in the crude oil information.  

(4)  Volumes represent sales of condensate and LPG from the LPG plant in Equatorial Guinea.  
(5)  We sold our Argentina assets in February 2008.  

Revenues from sales of crude oil and natural gas have accounted for 90% or more of consolidated revenues for each 
of the last three fiscal years. 

At December 31, 2009, our operated properties accounted for approximately 60% of our total production. Being the 
operator of a property improves our ability to directly influence production levels and the timing of projects, while also 
enhancing our control over operating expenses and capital expenditures.

Productive wells are producing wells and wells mechanically capable of production. A gross well is a well in which a 
working interest is owned. The number of gross wells is the total number of wells in which a working interest is 
owned. The number of net wells is the sum of the fractional working interests owned in gross wells expressed as 
whole numbers and fractions thereof. Wells with multiple completions are counted as one well in the table above.

(2)  Approximately 687,000 gross acres (407,000 net acres) will expire in 2010, 1.4 million gross acres (975,000 net 
acres) will expire in 2011, and 172,000 gross acres (121,000 net acres) will expire in 2012 if production is not 
established or we take no other action to extend the terms of the leases or concessions. 

Developed acreage is comprised of leased acres that are within an area spaced by or assignable to a productive well. 
Undeveloped acreage is comprised of leased acres with defined remaining terms and not within an area spaced by or 
assignable to a productive well. 

A gross acre is any leased acre in which a working interest is owned. A net acre is comprised of the total of the 
owned working interest(s) in a gross acre expressed in a fractional format.

 Includes successful exploratory wells drilled but not yet producing. 

A productive well is an exploratory, development or extension well that is not a dry well. A dry well (hole) is an 
exploratory, development, or extension well that proves to be incapable of producing either oil or gas in sufficient 
quantities to justify completion as an oil or gas well. 

As defined in the rules and regulations of the SEC, an exploratory well is a well drilled to find a new field or to find a 
new reservoir in a field previously found to be productive of oil or gas in another reservoir. A development well is part 
of a development project, which is defined as the means by which petroleum resources are brought to the status of 
economically producible. The number of wells drilled refers to the number of wells completed at any time during the 
respective year, regardless of when drilling was initiated. Completion refers to the installation of permanent 
equipment for production of oil or gas, or, in the case of a dry well, to reporting to the appropriate authority that the 
well has been abandoned. 

In addition to the wells drilled and completed in 2009 included in the table above, at December 31, 2009, we were in 
the process of drilling or completing 152 gross (113.2 net) wells in the Northern region of our US operations, two 
gross (0.7 net) onshore wells in the Southern region of our US operations, two gross (0.6 net) wells in the deepwater 
Gulf of Mexico, one gross (0.3 net) well in the North Sea, and one gross (0.6 net) well in China.

Marketing Activities   We seek opportunities to enhance the value of our US natural gas production by marketing 
directly to end-users and aggregating natural gas to be sold to natural gas marketers and pipelines. We sell our 
natural gas production at both market-based and fixed prices. In 2009, approximately 28% of natural gas sales were 
made pursuant to long-term contracts under either fixed or market-based prices. 

Crude oil, condensate and NGLs produced in the US and foreign locations are generally sold under short-term 
contracts at market-based prices adjusted for location and quality. In China, we sell crude oil into the local market 
under a long-term contract at market-based prices. In Israel, we sell natural gas under long-term contracts at 
negotiated prices. Crude oil and condensate are distributed through pipelines and by trucks or tankers to gatherers, 
transportation companies and refineries. 

Delivery Commitments   Some of our natural gas sales contracts specify the delivery of a fixed and determinable 
quantity of product. We have commitments to deliver approximately 220 Bcf of natural gas, net to our interest, to 
various customers in Israel through the year 2022. Approximately 90% of this amount will be delivered by 2015. We 
expect to fulfill the delivery commitments with proved developed and proved undeveloped reserves from the Mari-B 
and other nearby fields in Israel and we do not expect any shortfall. See International – Eastern Mediterranean (Israel 
and Cyprus). 

Significant Purchaser   Glencore Energy UK Ltd (Glencore) was the largest single non-affiliated purchaser of 2009 
production and purchased our share of production from the Alba field in Equatorial Guinea under a short-term sales 
contract, subject to renewal.  Sales to Glencore accounted for 25% of 2009 crude oil sales, or 16% of 2009 total oil 
and gas sales. No other single non-affiliated purchaser accounted for 10% or more of crude oil and natural gas sales 
in 2009. We believe that the loss of any one purchaser would not have a material effect on our financial position or 
results of operations since there are numerous potential purchasers of our production. 

Hedging Activities   Commodity prices were volatile in 2009 and prices for crude oil and natural gas are affected by a 
variety of factors beyond our control. We have used derivative instruments, and expect to do so in the future, in order 
to reduce commodity price uncertainty and increase cash flow predictability relating to the marketing of our crude oil 
and natural gas. For additional information, see Item 1A. Risk Factors – Hedging transactions may limit our potential 
gains and We are exposed to counterparty credit risk as a result of our receivables, hedging transactions, and cash 
investments, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, and Item 8. Financial Statements 
and Supplementary Data – Note 6. Derivative Instruments and Hedging Activities. 

Termination of Contracts   See Item 1A. Risk Factors – Our operations and investment in Ecuador may be adversely 
affected  by  the  country’s  unsettled  economic  and  political  environment,  Item  7.  Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations – Operating Outlook – Current Conditions in Ecuador, and 
Item 8. Financial Statements and Supplementary Data – 3. Impairments. 

Regulations 

Government Regulation   Exploration for, and production and marketing of, crude oil and natural gas are extensively 
regulated at the international, federal, state and local levels. Crude oil and natural gas development and production 
activities are subject to various laws and regulations (and orders of regulatory bodies pursuant thereto) governing a 
wide variety of matters, including, among others, allowable rates of production, transportation, prevention of waste 
and pollution and protection of the environment. Laws affecting the crude oil and natural gas industry are under 
constant review for amendment or expansion and frequently increase the regulatory burden on companies. Our ability 
to economically produce and sell crude oil and natural gas is affected by a number of legal and regulatory factors, 
including federal, state and local laws and regulations in the US and laws and regulations of foreign nations. Many of 
these governmental bodies have issued rules and regulations that are often difficult and costly to comply with, and 
that carry substantial penalties for failure to comply. These laws, regulations and orders may restrict the rate of crude 
oil and natural gas production below the rate that would otherwise exist in the absence of such laws, regulations and 
orders. The regulatory burden on the crude oil and natural gas industry increases our costs of doing business and 
consequently affects our profitability. See Item 1A. Risk Factors – We are subject to various governmental regulations 
and environmental risks that may cause us to incur substantial costs. 

Examples of US federal agencies with regulatory authority over our exploration for, and production and sale of, crude 
oil and natural gas include:  

•  the Bureau of Land Management (BLM) and the Minerals Management Service (MMS), which under laws such 
as the Federal Land Policy and Management Act, Endangered Species Act, National Environmental Policy Act 
and Outer Continental Shelf Lands Act have certain authority over our operations on federal lands, particularly 
in the Rocky Mountains and deepwater Gulf of Mexico; 

•  the US Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration, which 

under laws such as the Comprehensive Environmental Response, Compensation and Liability Act, as 
amended, the Resource Conservation and Recovery Act, as amended, the Oil Pollution Act of 1990, the Clean 
Air Act, the Clean Water Act, the Occupational Safety and Health Act and the recent Final Mandatory Reporting 
of Greenhouse Gases Rule have certain authority over environmental, health and safety matters affecting our 
operations as discussed below; 

18 

 
•  the Federal Energy Regulatory Commission, which under laws such as the Energy Policy Act of 2005 has 

certain authority over the marketing and transportation of crude oil and natural gas we produce onshore and 
from the deepwater Gulf of Mexico; 

•  the Department of Transportation, which has certain authority over the transportation of products, equipment 

and personnel necessary to our US onshore and deepwater Gulf of Mexico operations; and 

•  other federal agencies with certain authority over our business, such as the Internal Revenue Service and the 

SEC, as well as the NYSE upon which shares of our common stock are traded. 

In January 2010, the BLM announced that it will be issuing a new draft oil and gas leasing policy that will require, 
among other things, a more detailed environmental review prior to leasing oil and natural gas resources, increased 
public engagement in the development of master leasing and development plans prior to leasing areas where 
intensive new oil and gas development is anticipated, and a comprehensive parcel review process.  As the policy has 
not yet been released, we are not able to determine the impact these potential leasing policy changes may have on 
our business.  

Most of the states within which we operate have separate agencies with authority to regulate related operational and 
environmental matters.  Examples of such regulation on the operational side include the Greater Wattenberg Area 
Special Well Location Rule 318A, which was adopted by the Colorado Oil and Gas Conservation Commission to 
address oil and gas well drilling, production, commingling and spacing in the Wattenberg field, and the same 
Commission’s December 10, 2008 approval of a comprehensive update to statewide rules governing oil and gas 
operations in Colorado. These rules were reviewed by the Colorado legislature in its 2009 session and became 
effective in the second quarter of 2009, addressing areas such as public drinking water protection, monitoring and 
disclosure of chemicals used in drilling operations, erosion management and environment and wildlife protection. On 
the environmental side, Colorado Regulation Seven and requirements for storm water management plans were 
adopted by the Colorado Department of Environmental Quality, under delegation from the EPA, to regulate air 
emissions, water protection and waste handling and disposal relating to our oil and gas exploration and production. 

Some of the counties and municipalities within which we operate have adopted regulations or ordinances that impose 
additional restrictions on our oil and gas exploration and production.  An example is Garfield County, Colorado, which 
provides local land and road use restrictions affecting our Piceance basin operations and requires us to post bonds to 
secure any restoration obligations. 

Our international operations are subject to legal and regulatory oversight by energy-related ministries of our host 
countries, each having certain relevant energy or hydrocarbons laws.  Examples of these ministries include the 
Ecuador Ministry of Nonrenewable Natural Resources, the Equatorial Guinea Ministry of Mines, Industry and Energy, 
the Israel Ministry of National Infrastructures, and the UK Department of Energy and Climate Change.  An example of 
a law affecting our international operations is the UK Finance Act of 2006, which increased the income tax rate on our 
UK operations effective January 1, 2006. 

Environmental Matters   As a developer, owner and operator of crude oil and natural gas properties, we are subject to 
various federal, state, local and foreign country laws and regulations relating to the discharge of materials into, and 
the protection of, the environment. We must take into account the cost of complying with environmental regulations in 
planning, designing, drilling, operating and abandoning wells. In most instances, the regulatory requirements relate to 
the handling and disposal of drilling and production waste products, water and air pollution control procedures, and 
the remediation of petroleum-product contamination. Under state and federal laws, we could be required to remove or 
remediate previously disposed wastes, including wastes disposed of or released by us or prior owners or operators in 
accordance with current laws or otherwise, to suspend or cease operations in contaminated areas, or to perform 
remedial well plugging operations or cleanups to prevent future contamination. The EPA and various state agencies 
have limited the disposal options for hazardous and non-hazardous wastes. The owner and operator of a site, and 
persons that treated, disposed of or arranged for the disposal of hazardous substances found at a site, may be liable, 
without regard to fault or the legality of the original conduct, for the release of a hazardous substance into the 
environment. The EPA, state environmental agencies and, in some cases, third parties are authorized to take actions 
in response to threats to human health or the environment and to seek to recover from responsible classes of 
persons the costs of such action. Furthermore, certain wastes generated by our crude oil and natural gas operations 
that are currently exempt from treatment as hazardous wastes may in the future be designated as hazardous wastes 
and, therefore, be subject to considerably more rigorous and costly operating and disposal requirements. See Item 
1A. Risk Factors – We are subject to various governmental regulations and environmental risks that may cause us to 
incur substantial costs. 

Federal and state occupational safety and health laws require us to organize information about hazardous materials 
used, released or produced in our operations. Certain portions of this information must be provided to employees, 
state and local governmental authorities and local citizens. We are also subject to the requirements and reporting set 
forth in federal workplace standards. 

Certain state or local laws or regulations and common law may impose liabilities in addition to, or restrictions more 
stringent than, those described herein. 

We have made and will continue to make expenditures in our efforts to comply with environmental requirements. We 
do not believe that we have, to date, expended material amounts in connection with such activities or that compliance 

19 

 
with such requirements will have a material adverse effect on our capital expenditures, earnings or competitive 
position. Although such requirements do have a substantial impact on the crude oil and natural gas industry, they do 
not appear to affect us to any greater or lesser extent than other companies in the industry. 

Competition 

The crude oil and natural gas industry is highly competitive. We encounter competition from other crude oil and 
natural gas companies in all areas of operations, including the acquisition of seismic and lease rights on crude oil and 
natural gas properties and for the labor and equipment required for exploration and development of those properties. 
Our competitors include major integrated crude oil and natural gas companies and numerous independent crude oil 
and natural gas companies, individuals and drilling partnership programs. Many of our competitors are large, well 
established companies. Such companies may be able to pay more for seismic and lease rights on crude oil and 
natural gas properties and exploratory prospects and to define, evaluate, bid for and purchase a greater number of 
properties and prospects than our financial or human resources permit. Our ability to acquire additional properties 
and to discover reserves in the future will be dependent upon our ability to evaluate and select suitable properties and 
to consummate transactions in a highly competitive environment. See Item 1A. Risk Factors – We face significant 
competition and many of our competitors have resources in excess of our available resources. 

Geographical Data 

We have operations throughout the world and manage our operations by country. Information is grouped into five 
components that are all primarily in the business of crude oil, natural gas and NGL exploration, development and 
production: United States, West Africa, Eastern Mediterranean, North Sea, and Other International, Corporate and 
Marketing. See Item 8. Financial Statements and Supplementary Data – Note 15. Segment Information. 

Employees 

Our total number of employees increased from 1,571 at December 31, 2008 to 1,630 at December 31, 2009. The 
2009 year-end employee count includes 154 foreign nationals working as employees in Ecuador, Israel, the UK, 
Equatorial Guinea and Cameroon. We regularly use independent contractors and consultants to perform various field 
and other services. 

Offices 

Our principal corporate office, including our offices for US and international operations, is located at 100 Glenborough 
Drive, Suite 100, Houston, Texas 77067-3610. We maintain additional offices in Ardmore, Oklahoma and Denver, 
Colorado and in China, Cameroon, Ecuador, Equatorial Guinea, Israel and the UK. 

Title to Properties 

We believe that our title to the various interests set forth above is satisfactory and consistent with generally accepted 
industry standards, subject to exceptions that would not materially detract from the value of the interests or materially 
interfere with their use in our operations. Individual properties may be subject to burdens such as royalty, overriding 
royalty and other outstanding interests customary in the industry. In addition, interests may be subject to obligations 
or duties under applicable laws or burdens such as production payments, net profits interest, liens incident to 
operating agreements and for current taxes, development obligations under crude oil and natural gas leases or 
capital commitments under production sharing contracts or exploration licenses.

Item 1A.  Risk Factors  

Described below are certain risks that we believe are applicable to our business and the oil and gas industry in which 
we operate. There may be additional risks that are not presently material or known. You should carefully consider 
each of the following risks and all other information set forth in this Annual Report on Form 10-K.  

If any of the events described below occur, our business, financial condition, results of operations, liquidity or access 
to the capital markets could be materially adversely affected. In addition, the current global economic environment 
intensifies many of these risks.  

20 

 
Future economic conditions in the US and key international markets may materially adversely impact our 
operating results. 

The US and other world economies are slowly recovering from a recession which began in 2008 and extended into 
2009. Growth has resumed, but is modest.  There are likely to be significant long-term effects resulting from the 
recession and credit market crisis, including a future global economic growth rate that is slower than what was 
experienced in recent years.  In addition, more volatility may occur before a sustainable, yet lower, growth rate is 
achieved.   Global economic growth drives demand for energy from all sources, including fossil fuels.  A lower future 
economic growth rate will result in decreased demand growth for our crude oil and natural gas production as well as 
lower commodity prices, which will reduce our cash flows from operations and our profitability.  

Crude oil and natural gas prices are volatile and a substantial reduction in these prices could adversely 
affect our results and the price of our common stock. 

Our revenues, operating results and future rate of growth depend highly upon the prices we receive for our crude oil 
and natural gas production. Historically, the markets for crude oil and natural gas have been volatile and are likely to 
continue to be volatile in the future. For example, the NYMEX daily settlement price for the prompt month oil contract 
in 2009 ranged from a high of $81.37 per barrel to a low of $33.98 per barrel. The NYMEX daily settlement price for 
the prompt month natural gas contract in 2009 ranged from a high of $6.07 per MMBtu to a low of $2.51 per MMBtu. 
The markets and prices for crude oil and natural gas depend on factors beyond our control. These factors include 
demand for crude oil and natural gas, which fluctuates with changes in market and economic conditions, and other 
factors, including: 

•  worldwide and domestic supplies of crude oil and natural gas; 
•  actions taken by foreign oil and gas producing nations; 
•  political conditions and events (including instability or armed conflict) in crude oil or natural gas producing 

regions; 

•  the level of global crude oil and natural gas inventories; 
•  the price and level of imported foreign crude oil and natural gas; 
•  the price and availability of alternative fuels, including coal and biofuels; 
•  the availability of pipeline capacity and infrastructure; 
•  the availability of crude oil transportation and refining capacity; 
•  weather conditions; 
•  electricity generation; 
•  domestic and foreign governmental regulations and taxes; and 
•  the overall economic environment. 

Significant declines in crude oil and natural gas prices for an extended period may have the following effects on our 
business: 

•  limiting our financial condition, liquidity, and/or ability to finance planned capital expenditures and operations; 
•  reducing the amount of crude oil and natural gas that we can produce economically; 
•  causing us to delay or postpone some of our capital projects; 
•  reducing our revenues, operating income and cash flows; or 
•  limiting our access to sources of capital, such as equity and long-term debt. 

In addition, significant declines in the forward commodity price curves may result in the following: 

•  a reduction in the carrying value of our crude oil and natural gas properties; or 
•  a reduction in the carrying value of goodwill. 

We recorded asset impairment charges during 2009. If commodity prices decline during 2010, there could be 
additional impairments of our oil and gas assets or other investments or an impairment of goodwill. 

Market conditions may restrict our ability to obtain funds for future development and working capital needs, 
which may limit our financial flexibility. 

During 2009, credit markets recovered but remain vulnerable to unpredictable shocks should weaker than expected 
economic growth persist.  We have a significant development project inventory and an extensive exploration portfolio, 
which will require substantial future investment. We and our partners will need to seek financing in order to fund these 
or other activities. Our future access to capital, as well as that of our partners and contractors, could be limited if the 
debt or equity markets are constrained. This could significantly delay development of our property interests. 

Failure to fund continued capital expenditures could adversely affect our properties. 

Our exploration, development, and acquisition activities require substantial capital expenditures especially in the case 
of our active drilling programs, such as the Wattenberg field, and our significant exploration and development 
programs in the deepwater Gulf of Mexico, West Africa and Israel. Significant capital investments on our inventory of 
major development projects will start next year and are estimated to be approximately $1 billion per year in 2010 and 
2011.  First production from these projects is not expected until 2011 and thereafter. Historically, we have funded our 
capital expenditures through a combination of cash flows from operations, our revolving bank credit facility and debt 
issuances. Future cash flows are subject to a number of variables, such as the level of production from existing wells, 

21 

 
prices of crude oil and natural gas, and our success in finding, developing and producing new reserves. If revenues 
were to decrease as a result of lower crude oil and natural gas prices or decreased production, and our access to 
debt or capital were limited, we would have a reduced ability to replace our reserves, resulting in a decrease in 
production over time. If our cash flows from operations are not sufficient to meet our obligations and fund our capital 
budget, we may not be able to access capital markets on an economic basis to meet these requirements. If we are 
not able to fund our capital expenditures, interests in some properties might be reduced or forfeited as a result. 

Indebtedness may limit our liquidity and financial flexibility. 

As of December 31, 2009, we had long-term indebtedness of $2 billion (excluding unamortized discount), with 
$382 million drawn under our bank credit facility. Our indebtedness represented 25% of our total book capitalization 
at December 31, 2009. 

Our indebtedness affects our operations in several ways, including the following: 

•  a portion of our cash flows from operating activities must be used to service our indebtedness and is not 

available for other purposes; 

•  we may be at a competitive disadvantage as compared to similar companies that have less debt; 
•  the covenants contained in the agreements governing our outstanding indebtedness and future indebtedness 
may limit our ability to borrow additional funds, pay dividends and make certain investments and may also 
affect our flexibility in planning for, and reacting to, changes in the economy and in our industry; 

•  additional financing in the future for working capital, capital expenditures, acquisitions, general corporate or 

other purposes may have higher costs and more restrictive covenants; 

•  additional financing in the future is likely to have higher costs due to the negative impact of the credit market 

crisis which restricted access to the bond markets;  

•  changes in the credit ratings of our debt may negatively affect the cost, terms, conditions and availability of 
future financing, and lower ratings will increase the interest rate and fees we pay on our revolving credit 
facility; and 

•  we may be more vulnerable to general adverse economic and industry conditions. 

We may incur additional debt in order to fund our exploration, development and acquisition activities such as our 
pending acquisition of additional US Rocky Mountain assets. A higher level of indebtedness increases the risk that 
our liquidity may become impaired and we default on our debt obligations. Our ability to meet our debt obligations and 
reduce our level of indebtedness depends on future performance. General economic conditions, crude oil and natural 
gas prices and financial, business and other factors will affect our operations and our future performance. Many of 
these factors are beyond our control and we may not be able to generate sufficient cash flow to pay the interest on 
our debt, and future working capital, borrowings and equity financing may not be available to pay or refinance such 
debt. 

Hedging transactions may limit our potential gains. 

In order to reduce commodity price uncertainty and increase cash flow predictability relating to the marketing of our 
crude oil and natural gas, we enter into crude oil and natural gas price hedging arrangements with respect to a 
portion of our expected production. Our hedges, consisting of a series of contracts, are limited in duration, usually for 
periods of one to three years. While intended to reduce the effects of volatile crude oil and natural gas prices, such 
transactions may limit our potential gains if crude oil and natural gas prices rise over the price established by the 
arrangements.  

Global commodity price fluctuation has been significant in 2009. Such volatility disrupts our ability to forecast and, as 
a result, we may become even more reliant on our hedging program.  In trying to manage our exposure to commodity 
price risk, we may end up hedging too much or too little, depending upon how our crude oil or natural gas volumes 
and our production mix fluctuate in the future. In addition, hedging transactions may expose us to the risk of financial 
loss in certain circumstances, including instances in which our production is less than expected; there is a widening of 
price basis differentials between delivery points for our production and the delivery point assumed in the hedge 
arrangement; the counterparties to our futures contracts fail to perform under the contracts; or a sudden unexpected 
event materially impacts crude oil or natural gas prices.  We cannot assure that our hedging transactions will reduce 
the risk or minimize the effect of volatility in crude oil or natural gas prices. 

We are exposed to counterparty credit risk as a result of our receivables, hedging transactions and cash 
investments. 

We are exposed to risk of financial loss from trade, joint venture, and other receivables.  We sell our crude oil, natural 
gas and NGLs to a variety of purchasers.   In addition, we are the operator on large joint venture development 
projects such as Aseng in Equatorial Guinea and Tamar in Israel. As operator of the joint ventures, we pay joint 
venture expenses and bill our nonoperating partners for their respective shares of joint venture costs. Some of our 
purchasers and joint venture partners are not as creditworthy as we are and may experience liquidity problems. 
Credit enhancements have been obtained from some parties in the way of parental guarantees or letters of credit, 
including our largest international crude oil purchaser; however, not all of our trade credit is protected through 
guarantees or credit support.  Nonperformance by a trade creditor or joint venture partner could result in significant 
financial losses.    

22 

 
We also monitor the creditworthiness of our counterparties on an ongoing basis. However, disruptions in the financial 
markets could lead to sudden changes in a counterparty’s liquidity, which could impair their ability to perform under 
the terms of the hedging contract. We are unable to predict sudden changes in financial market conditions or a 
counterparty’s creditworthiness or ability to perform. Even if we do accurately predict sudden changes, our ability to 
negate the risk may be limited depending upon market conditions. 

Our hedging transactions expose us to risk of financial loss if a counterparty fails to perform under a contract.  To 
mitigate counterparty credit risk we conduct our hedging activities with a diverse group of major financial 
institutions.  We use master agreements which allow us, in the event of default, to elect early termination of all 
contracts with the defaulting counterparty. If we choose to elect early termination, all asset and liability positions with 
the defaulting counterparty would be “net settled” at the time of election. “Net settlement” refers to a process by which 
all transactions between counterparties are resolved into a single amount owed by one party to the other.  

During periods of falling commodity prices, such as in late 2008 and first quarter 2009, our hedge receivable positions 
increase, which increases our counterparty exposure. If the creditworthiness of our counterparties, which are major 
financial institutions, deteriorates and results in their nonperformance, we could incur a significant loss.  

We have over $1 billion in cash and cash equivalents invested in money market funds and short-term deposits with 
major financial institutions. During the first half of 2009, we shortened the duration of our bank deposits and held over 
50% of our cash and cash equivalents in US Treasury securities. We maintained this investment posture well into the 
third quarter of 2009 before we started to reduce our US Treasury holdings in favor of reinvestment back into money 
market funds and time deposits with highly rated banks. We monitor the creditworthiness of the banks and financial 
institutions with which we invest and review the securities underlying our investment accounts. However, we are 
unable to predict sudden changes in solvency of our financial institutions. In the event of a bank failure, we could 
incur a significant loss. 

We may not have enough insurance to cover all of the risks we face, which could result in significant 
financial exposure. 

Exploration for and production of crude oil and natural gas can be hazardous, involving natural disasters and other 
unfortuitous events such as blowouts, cratering, fire and explosion and loss of well control which can result in 
damage to or destruction of wells or production facilities, injury to persons, loss of life, or damage to property and the 
environment. Our international operations are also subject to political risk. 

In accordance with industry practices, we maintain insurance against many, but not all, potential perils confronting our 
operations and in coverage amounts and deductible levels that we believe to be economic. Consistent with that 
profile, our insurance program is structured to provide us financial protection from unfavorable loss severity resulting 
from damages to or the loss of physical assets or loss of human life, liability claims of third parties, and business 
interruption (loss of production) attributed to certain assets. Although we believe the coverages and amounts of 
insurance carried are adequate, we may not have sufficient protection against some of the risks we face, because we 
chose not to insure certain risks, insurance is not available on commercially reasonable terms or actual losses 
exceed coverage limits. If an event occurs that is not covered by insurance or not fully protected by insured limits, it 
could have an adverse impact on our financial condition, results of operations and cash flows. 

Failure to effectively execute our major development projects could result in significant delays and/or cost 
over-runs, damage to our reputation, limitations on our growth and negative effects on our operating results. 

We currently have an extensive inventory of major development projects, several of which will take years before first 
production, including the Aseng oil project, Tamar, Gunflint, and others.  Some of these projects, such as oil and gas 
projects in West Africa, have a great deal of complexity. This level of development will require significant effort from 
our management and technical personnel as well as place additional burden on our financial resources and internal 
financial controls. We may not be able to attract and retain personnel with the skills necessary to bring complicated 
projects to successful conclusions.   

In addition, we will have increased dependency on third-party technology and service providers and other vendors for 
these complex projects.  Significant delays in delivery of essential items or performance of services, cost overruns, 
vendor insolvency, or other critical supply failure, could adversely affect development of our projects.  

We may not be able to manage these and other risks effectively. 

We may be unable to make attractive acquisitions, integrate acquired businesses and/or assets, or adjust to 
the effects of divestitures, causing a disruption to our business. 

One aspect of our business strategy calls for acquisitions of businesses and assets that complement or expand our 
current business, such as our Patina Merger in 2005, our purchase of U.S. Exploration in 2006 and the pending 
acquisition of additional US Rocky Mountain assets.  This may present greater risks for us than those faced by peer 
companies that do not consider acquisitions as a part of their business strategy. We cannot provide assurance that 
we will be able to identify attractive acquisition opportunities. Even if we do identify attractive opportunities, we cannot 
provide assurance that we will be able to complete the acquisition due to capital market constraints, even if such 
capital is available on commercially acceptable terms. If we acquire another business, we could have difficulty 
integrating its operations, systems, management and other personnel and technology with our own, or could assume 
unidentified or unforeseeable liabilities, resulting in a loss of value.  

23 

 
We also engage in portfolio rationalization, such as the sale of our interest in Argentina in 2008, and the majority of 
our Gulf of Mexico shelf properties in 2006. These transactions can also result in changes in operations, systems, or 
management and other personnel.    

Organizational modifications due to acquisitions, divestitures or portfolio rationalizations, or other strategic changes 
can alter the risk and control environments, disrupt ongoing business, distract management and employees, increase 
expenses and adversely affect results of operations. Even if these difficulties could be overcome, we cannot provide 
assurance that the anticipated benefits of any acquisition, divestiture or other strategic change would be realized. 

Estimates of crude oil and natural gas reserves are not precise. 

There are numerous uncertainties inherent in estimating crude oil and natural gas reserves and their value, including 
factors that are beyond our control. Reservoir engineering is a subjective process of estimating underground 
accumulations of crude oil and natural gas that cannot be measured in an exact manner. In accordance with the 
SEC’s revisions to rules for oil and gas reserves reporting, which we adopted effective December 31, 2009, our 
reserves estimates are based on 12-month average prices; therefore, reserves quantities will change when actual 
prices increase or decrease. The estimates depend on a number of factors and assumptions that may vary 
considerably from actual results, including: 

•  historical production from the area compared with production from other areas; 
•  the assumed effects of regulations by governmental agencies, including the impact of the SEC’s new oil and 

gas company reserves reporting requirements; 

•  assumptions concerning future crude oil and natural gas prices; 
•  future operating costs; 
•  severance and excise taxes; 
•  development costs; and 
•  workover and remedial costs.  

For these reasons, estimates of the economically recoverable quantities of crude oil and natural gas attributable to 
any particular group of properties, classifications of those reserves based on risk of recovery and estimates of the 
future net cash flows expected from them prepared by different engineers or by the same engineers but at different 
times may vary substantially. Accordingly, reserves estimates may be subject to upward or downward adjustment, 
and actual production, revenue and expenditures with respect to our reserves likely will vary, possibly materially, from 
estimates. 

Additionally, because some of our reserves estimates are calculated using volumetric analysis, those estimates are 
less reliable than the estimates based on a lengthy production history. Volumetric analysis involves estimating the 
volume of a reservoir based on the net feet of pay of the structure and an estimation of the area covered by the 
structure. In addition, realization or recognition of proved undeveloped reserves will depend on our development 
schedule and plans. A change in future development plans for proved undeveloped reserves could cause the 
discontinuation of the classification of these reserves as proved. 

Exploration, development and production risks and natural disasters could result in liability exposure or the 
loss of production and revenues. 

Our operations are subject to hazards and risks inherent in the drilling, production and transportation of crude oil and 
natural gas, including: 

•  pipeline ruptures and spills; 
•  fires; 
•  explosions, blowouts and cratering; 
•  formations with abnormal pressures; 
•  equipment malfunctions; 
•  hurricanes, such as Gustav and Ike in 2008, which could affect our operations in areas such as the Gulf Coast 

and deepwater Gulf of Mexico, and cyclones, which could affect our operations offshore China; and 

•  other natural disasters. 

Any of these can result in loss of hydrocarbons, environmental pollution and other damage to our properties or the 
properties of others. 

Exploration and development drilling may not result in commercially productive reserves. 

We do not always encounter commercially productive reservoirs through our drilling operations. The wells we drill or 
participate in may not be productive and we may not recover all or any portion of our investment in those wells. The 
seismic data and other technologies we use do not allow us to know conclusively prior to drilling a well that crude oil 
or natural gas is present or may be produced economically, and area well data and other data may be limited or less-
developed in some of the international areas in which we explore. The cost of drilling, completing and operating a well 
is often uncertain, and cost factors can adversely affect the economics of a project. Our efforts will be unprofitable if 
we drill dry holes or wells that are productive but do not produce enough reserves to return a profit after drilling, 
operating and other costs. Further, our drilling operations may be curtailed, delayed or canceled as a result of a 
variety of factors, including: 

24 

 
•  unexpected drilling conditions; 
•  title problems; 
•  pressure or other irregularities in formations; 
•  equipment failures or accidents; 
•  adverse weather conditions; 
•  compliance with environmental and other governmental requirements; and 
•  increases in the cost of, or shortages or delays in the availability of, drilling rigs and equipment. 

The unavailability or high cost of drilling rigs, equipment, supplies, personnel and other oil field services 
could adversely affect our ability to execute our exploration and development plans on a timely basis and 
within our budget. 

Our industry is cyclical and, from time to time, there is a shortage of drilling rigs, equipment, supplies or qualified 
personnel. During these periods, the costs of rigs, equipment and supplies are substantially greater and their 
availability may be limited, particularly in areas of high activity and demand in which we concentrate, such as the 
Rocky Mountains and deepwater Gulf of Mexico, and in some international locations that typically have more limited 
availability of equipment and personnel, such as Ecuador, Israel and West Africa. During periods of increasing levels 
of exploration and production in response to strong demand for crude oil and natural gas, the demand for oilfield 
services and the costs of these services increase. Additionally, these services may not be available on commercially 
reasonable terms. 

In the current economy, even though commodity prices have fallen from the high levels experienced in 2008, the 
costs of drilling rigs, equipment and supplies, though somewhat reduced, have not decreased to the levels that 
existed before the run-up in commodity prices that occurred in the first half of 2008.  If drilling costs decline 
significantly, our long-term drilling rig contracts may require us to pay rates higher than the current market. See Item 
7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contractual Obligations 
for additional information on drilling rig contracts.  As a result, an increase in profits may be more dependant on cost 
reduction than in previous years.  

Exploration and development in the deepwater Gulf of Mexico involves significant financial risks. 

Much of the deepwater Gulf of Mexico area lacks the physical and oilfield service infrastructure necessary for 
production. As a result, development of a deepwater discovery, such as Gunflint, may be a lengthy process and 
require substantial capital investment. We participate in certain other projects, such as Isabela and Double Mountain, 
for which we are not the operator. If we are not the operator of a project, we may have limited ability to exercise 
influence over the project or its costs. This could prevent the realization of targeted return on capital or lead to 
unexpected future losses.  

In addition, there is limited availability of suitable drilling rigs, drilling equipment, support vessels, production and 
transportation infrastructure, qualified operating personnel, and deepwater drilling rigs are typically subject to long-
term contracts. This can lead to difficulty and delays in consistently obtaining drilling rigs and other equipment and 
services at acceptable rates, which, in turn, may lead to projects being delayed or increased costs. This also makes it 
difficult to estimate the timing of production.  

We face significant competition and many of our competitors have resources in excess of our available 
resources. 

We operate in the highly competitive areas of crude oil and natural gas exploration, exploitation, acquisition and 
production. We face intense competition from a large number of independent, technology-driven companies as well 
as both major and other independent crude oil and natural gas companies in a number of areas such as: 

•  seeking to acquire desirable producing properties or new leases for future exploration; 
•  marketing our crude oil and natural gas production;  
•  seeking to acquire the equipment and expertise necessary to operate and develop properties; and 
•  attracting and retaining employees with certain skills. 

Many of our competitors have financial and other resources substantially in excess of those available to us. For 
example, in the deepwater Gulf of Mexico we compete with major integrated crude oil and natural gas companies and 
in international locations such as the North Sea we compete with major integrated crude oil and natural gas 
companies as well as state-controlled multinational companies.  

In addition, the economic recession has increased competitive pressures. Crude oil and natural gas exploration and 
production companies, as well as service and drilling companies, are striving to improve efficiency and profitability, 
primarily through cost reduction. This highly competitive environment could have an adverse impact on our business.     

The marketability of our Rocky Mountain and Gulf of Mexico production is dependent upon transportation 
and processing facilities over which we may have no control.  

The marketability of our production from the Rocky Mountain area and the deepwater Gulf of Mexico depends in part 
upon the availability, proximity and capacity of pipelines, natural gas gathering systems and processing facilities. We 
deliver crude oil and natural gas produced from these areas through gathering systems and pipelines that we do not 
own. The lack of availability of capacity on these systems and facilities could reduce the price offered for our 

25 

 
production or result in the shut-in of producing wells or the delay or discontinuance of development plans for 
properties. Although we have some contractual control over the transportation of our production through some firm 
transportation arrangements, third-party systems and facilities may be temporarily unavailable due to market 
conditions or mechanical or other reasons, or may not be available to us in the future at a price that is acceptable to 
us. Any significant change in market factors or other conditions affecting these infrastructure systems and facilities, 
as well as any delays in constructing new infrastructure systems and facilities, could harm our business and, in turn, 
our financial condition, results of operations and cash flows.  

Our international operations may be adversely affected by economic and political developments. 

We have significant international crude oil and natural gas operations compared to companies we consider to be our 
peers, with approximately 44% of our 2009 consolidated sales volumes coming from international operations. These 
operations may be adversely affected by political and economic developments, including the following: 

•  war, terrorist acts, civil disturbances, or territorial disputes, such as may occur in regions that encompass our 

operations, including Ecuador, Israel and West Africa; 

•  loss of revenue, property and equipment as a result of actions taken by foreign crude oil and natural gas 
producing nations, such as expropriation or nationalization of assets and renegotiation, modification or 
nullification of existing contracts, such as may occur pursuant to the hydrocarbons law enacted in 2006 by the 
government of Equatorial Guinea; 

•  changes in taxation policies, such as the UK Finance Act of 2006, which increased the income tax rate on our 
UK operations effective January 1, 2006, and the China Petroleum Special Profits Tax enacted in 2006, which 
imposed an excise tax on crude oil produced in the country; 

•  laws and policies of the US and foreign jurisdictions affecting foreign investment, taxation, trade and business 

conduct; 

•  foreign exchange restrictions; 
•  international monetary fluctuations and changes in the relative value of the US dollar as compared with the 

currencies of other countries in which we conduct business, such as the UK; and 

•  other hazards arising out of foreign governmental sovereignty over areas in which we conduct operations. 

We may not have enough insurance to cover any loss of property resulting from these risks. 

Our operations and investment in Ecuador may be adversely affected by the country's unsettled economic 
and political environment. 

The economic and political environment in Ecuador has become increasingly unsettled. We are aware that the 
Government of Ecuador is taking steps to renegotiate contracts or, in some cases, remove international oil and gas 
companies from its borders. We continue to have significant delinquent accounts and unpaid invoices related to 
electricity sales from our Machala power plant, and we recently entered into independent power purchase 
agreements for such sales, the long-term effect of which on payment is unknown. On August 24, 2009, we became 
aware that our proposed plan of development for the Amistad field (offshore Ecuador), which had been submitted to 
Ecuador’s National Bureau of Hydrocarbons, had been rejected. In addition, on December 31, 2009, Ecuador’s state 
oil company (Petroecuador) requested that Ecuador’s Minister of Nonrenewable Natural Resources commence 
termination of our production sharing contract. On February 11, 2010, the Minister notified us of Petroecuador’s 
request by delivering to us a copy of a letter of non-compliance dated December 31, 2009.  The Minister provided us 
with 60 business days to respond to the allegations contained in the letter. We are uncertain as to the potential 
outcome of this matter, resolution of which could ultimately lead to a further reduction in the value of our investments 
in Ecuador which, as of December 31, 2009, had a net book value of approximately $72 million. See Item 8. Financial 
Statements and Supplementary Data – Note 3. Asset Impairments. 

We are subject to various governmental regulations and environmental risks that may cause us to incur 
substantial costs. 

From time to time, in varying degrees, political developments and federal and state laws and regulations affect our 
operations. In particular, price controls, taxes and other laws relating to the crude oil and natural gas industry, 
changes in these laws and changes in administrative regulations have affected and in the future could affect crude oil 
and natural gas production, operations and economics. We cannot predict how agencies or courts will interpret 
existing laws and regulations or the effect these adoptions and interpretations may have on our business or financial 
condition. 

Our business is subject to laws and regulations promulgated by international, federal, state and local authorities 
relating to the exploration for, and the development, production and marketing of, crude oil and natural gas, as well as 
safety matters. Legal requirements are frequently changed and subject to interpretation and we are unable to predict 
the ultimate cost of compliance with these requirements or their effect on our operations. We may be required to 
make significant expenditures to comply with governmental laws and regulations. 

Our operations are subject to complex international, federal, state and local environmental laws and regulations 
including, for example, in the case of federal laws, the Comprehensive Environmental Response, Compensation and 
Liability Act, as amended, the Resource Conservation and Recovery Act, as amended, the Oil Pollution Act of 1990, 
the Clean Air Act, the Clean Water Act and the Occupational Safety and Health Act. Environmental laws and 
regulations change frequently and the implementation of new, or the modification of existing, laws or regulations 

26 

 
could negatively impact our operations. The discharge of natural gas, crude oil, or other pollutants into the air, soil or 
water may give rise to significant liabilities on our part to the government and third parties and may require us to incur 
substantial costs of remediation. In addition, we may incur costs and penalties in addressing regulatory agency 
procedures involving instances of possible non-compliance. 

Increased regulation of business practices could result in increased operating costs. 

The current trend is toward increased regulation of business practices and additional reporting requirements. For 
example the EPA has recently issued the Final Mandatory Reporting of Greenhouse Gases Rule, which requires 
many suppliers of fossil fuels or industrial chemicals, manufacturers of vehicles and engines, and other facilities that 
emit 25,000 metric tons or more of carbon dioxide equivalent per year to begin collecting greenhouse gas emissions 
data under a new reporting system on January 1, 2010 with the first annual report due March 31, 2011. We will be 
subject to these new reporting requirements, which will result in additional effort on the part of our personnel. In 
addition, other pending legislation, such as the pending climate change legislation that includes establishing a “cap 
and trade” system for restricting greenhouse gas emissions in the US, or pending hydraulic fracturing legislation that 
would subject the process of hydraulic fracturing to regulation under the Safe Drinking Water Act, if enacted, will 
require an unprecedented compliance effort on the part of companies in the oil and gas industry. We may be required 
to make significant expenditures to comply with additional reporting requirements. 

The proposed US federal budget for fiscal year 2011 includes certain provisions that, if passed as originally 
submitted, will have an adverse effect on our financial position, results of operations, and cash flows. 

On February 1, 2010, the Obama administration released its proposed federal budget for fiscal year 2011.  The 
proposed budget would repeal many tax incentives and deductions that are currently used by US oil and gas 
companies and impose new taxes. The provisions include: elimination of the ability to fully deduct intangible drilling 
costs in the year incurred; increases in the taxation of foreign source income; levy of an excise tax on Gulf of Mexico 
oil and gas production; repeal of the manufacturing tax deduction for oil and gas companies; increase in the 
geological and geophysical amortization period for independent producers; and implementation of a fee on non-
producing leases located on federal lands.  

If these proposals are enacted, our taxes will increase, potentially significantly, which would have a negative impact 
on our net income and cash flows. This could also reduce our drilling activities. Since none of these proposals have 
yet to be voted on or become law, we do not know the ultimate impact they  may have on our business. 

The adoption of pending climate change legislation could result in increased operating costs, create delays 
in our obtaining air pollution permits for new or modified facilities, and reduce demand for the crude oil and 
natural gas we produce. 

In June 2009, the House of Representatives passed the American Clean Energy and Security Act of 2009, also 
known as the Waxman-Markey Bill. The Senate’s version, The Clean Energy Jobs and American Power Act, or the 
Boxer-Kerry Bill, has been introduced, but has not passed. Although these bills include several differences that 
require reconciliation before becoming law, both bills contain the basic feature of establishing a “cap and trade” 
system for restricting greenhouse gas emissions in the US. Under such system, certain sources of greenhouse gas 
emissions would be required to obtain greenhouse gas emission “allowances” corresponding to their annual 
emissions of greenhouse gases. The number of emission allowances issued each year would decline as necessary 
to meet overall emission reduction goals. As the number of greenhouse gas emission allowances declines each year, 
the cost or value of allowances is expected to escalate significantly. The ultimate outcome of this legislative initiative 
remains uncertain.   In addition to the pending climate legislation, the EPA has issued greenhouse gas monitoring 
and reporting regulations that went into effect January 1, 2010, and require reporting by regulated facilities by March 
2011 and annually thereafter.  Beyond measuring and reporting, the EPA issued an “Endangerment Finding” under 
section 202(a) of the Clean Air Act, concluding greenhouse gas pollution threatens the public health and welfare of 
current and future generations.  The EPA has proposed regulation that would require permits for and reductions in 
greenhouse gas emissions for certain facilities, and may issue final rules this year. Since approximately 60% of our 
2009 crude oil production and 51% of our 2009 natural gas production derive from the US, any laws or regulations 
that may be adopted to restrict or reduce emissions of US greenhouse gases could require us to incur increased 
operating costs, and could have an adverse effect on demand for the crude oil and natural gas we produce.    

Federal hydraulic fracturing legislation could increase our costs and restrict our access to oil and gas 
reserves. 

Several proposals are before Congress that, if implemented, would subject the process of hydraulic fracturing to 
regulation under the Safe Drinking Water Act. Hydraulic fracturing involves the injection of water, sand and chemicals 
under pressure into rock formations to stimulate natural gas production. We find that the use of hydraulic fracturing is 
necessary to produce commercial quantities of crude oil and natural gas from many reservoirs. Such legislation could 
have a significant impact on our development of the Wattenberg field, our largest onshore US field. 

Although it is not possible at this time to predict the final outcome of the legislation regarding hydraulic fracturing, any 
new federal restrictions on hydraulic fracturing that may be imposed in areas in which we conduct business could 
significantly increase our operating, capital and compliance costs as well as delay our ability to develop oil and gas 
reserves. 

27 

 
Derivatives regulation could restrict our ability to execute commodity derivative instruments as a hedge 
against fluctuating commodity prices. 

Various measures are being proposed by committees of Congress, the US Treasury Department, and other agencies 
to restrict the use of over-the-counter (OTC) derivative instruments.  These proposals include, but are not limited to, 
requiring cash collateral on all OTC derivatives and requiring all OTC derivatives to be executed and settled through 
an exchange system. 

Although we do not currently know the exact form any final legislation or rule-making activity will take, any restriction 
on the use of OTC instruments could have a significant impact on our business. Limits on the use of OTC instruments 
could significantly reduce our ability to execute strategic price hedges to reduce price uncertainty and to protect cash 
flows.  In addition, cash collateral requirements could create significant liquidity issues and exchange system trades 
may restrict our ability to execute derivative instruments to fit our strategic needs. 

Healthcare reform legislation could adversely impact us. 

On November 7, 2009, the House of Representatives passed its healthcare reform bill, the Affordable Health Care for 
America Act, H.R. 3962. Among other initiatives, this bill authorizes the creation of a national public plan that would 
negotiate rates with providers and would be offered through a new national health insurance exchange market. On 
December 24, 2009, the Senate passed its own version of a healthcare reform bill, the Patient Protection and 
Affordable Care Act, H.R. 3590. The Senate bill contains no provision for a public plan but does authorize the 
creation of at least two multi-state plans.  

At this time, it remains unclear how or when the differences between the two bills will be resolved, or if a final bill 
ultimately will be enacted. Various healthcare reform proposals have also emerged at the state level. We cannot 
predict what healthcare initiatives, if any, will be implemented at the federal or state level, or the effect any future 
legislation or regulation will have on us. However, an expansion in government’s role in the US healthcare industry 
could have a significant impact on our employment benefits and related costs. 

We face various risks associated with the trend toward increased activism against oil and gas development 
activities. 

Opposition toward oil and gas drilling and development activity has been growing domestically as well as in countries 
belonging to the Organization for Economic Cooperation and Development (OECD), an international group of 
member countries sharing a commitment to democratic government and market economy.  Companies in the 
petroleum industry, such as us, are often the target of activist efforts regarding safety, human rights, environmental 
compliance and business practices.  Anti-development activists are working to, among other things, reduce access to 
federal and state government lands and delay or cancel certain projects such as development of oil shale.   

Future activist efforts could result in the following: 

• 
• 
• 
• 
• 
• 
• 

delay or denial of drilling permits; 
shortening of lease terms or reduction in lease size; 
restrictions on installation or operation of gathering or processing facilities;  
damaging publicity about us; 
increased costs of doing business;  
reduction in demand for our products; and 
other adverse affects on our ability to develop our properties and expand production 

Our need to incur costs associated with responding to these initiatives or complying with any resulting new legal or 
regulatory requirements resulting from these activities that are substantial and not adequately provided for, could 
have a material adverse effect on our business, financial condition and results of operations.    

Provisions in our Certificate of Incorporation and Delaware law may inhibit a takeover of us. 

Under our Certificate of Incorporation, our Board of Directors is authorized to issue shares of our common or 
preferred stock without approval of our shareholders. Issuance of these shares could make it more difficult to acquire 
us without the approval of our Board of Directors as more shares would have to be acquired to gain control. In 
addition, Delaware law imposes restrictions on mergers and other business combinations between us and any holder 
of 15% or more of our outstanding common stock. These provisions may deter hostile takeover attempts that could 
result in an acquisition of us that would have been financially beneficial to our shareholders.

Item 3.   Legal Proceedings 

Purchaser Bankruptcy     We had an exposure from crude oil sales for the months of June and July 2008 to 
SemCrude, L.P. (SemCrude), a subsidiary of SemGroup, L.P. (SemGroup).  On July 22, 2008, SemGroup, including 
SemCrude, filed a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code under Case Number 
08-11525 (BLS) in the United States Bankruptcy Court for the District of Delaware. During 2008, we determined that 
the carrying value of our receivable of $71 million should be reduced by $38 million. Based upon the confirmation of 
SemCrude's plan for reorganization on October 26, 2009 and further based upon a settlement reached with 
SemCrude on October 27, 2009, we further reduced the carrying value of our receivable by $12 million. We have 
received distributions of approximately $21 million from SemCrude and believe the disposition of this matter to be 
finally determined. 

Legal Proceedings     We are involved in various legal proceedings, including the foregoing matters in the ordinary 
course of business. These proceedings are subject to the uncertainties inherent in any litigation. We are defending 
ourselves vigorously in all such matters and we do not believe that the ultimate disposition of such proceedings will 
have a material adverse effect on our financial position, results of operations or cash flows.   

Item 4.   Submission of Matters to a Vote of Security Holders

international projects, crude oil and natural gas, and near, medium and long-term opportunities. 

Strategy   We endeavor to continue our strong historic growth trend (7.9% average annual production growth rate 
from 2000 to 2009) to deliver superior value to our shareholders.  We primarily focus on organic growth from 
exploration and development drilling, and we augment that with a strong, periodic new business development 
(mergers and acquisition) capability. We concentrate on basins or plays where we have strategic competitive 
advantage and which we believe offer superior returns. Core operating areas are the onshore US and deepwater Gulf 
of Mexico and the offshore Eastern Mediterranean and West Africa. We actively manage our portfolio with periodic 
divestments to “high grade” the portfolio. As a result of our continued exploration success, we are focused on the 
development of a significant portfolio of major projects in a number of key operating areas including, among others, 
Galapagos and Gunflint in the deepwater Gulf of Mexico, Tamar in Israel and Aseng and Belinda in West Africa. Our 
major development projects typically offer long life, sustained cash flows after investment and attractive financial 
returns. We maintain a balanced portfolio between US and international assets and a balanced geographic and 
political risk profile.  We also maintain a diversity of production mix between oil, US natural gas production and 
international gas.   

Financial and Operating Results     2009 was a challenging year in the energy industry due to the prolonged 
recession, constraint in the credit markets, and commodity price volatility. These conditions resulted in our reduced 
net income and cash flows from operations. We reduced our capital spending program from our 2008 level as an 
outcome of the financial crisis. However, we were able to move forward on several major development projects as 
well as pursue additional exploration opportunities which resulted in important new discoveries, and we maintained 
our strong balance sheet and ample liquidity levels. 

Our 2009 financial results included the following: 

•  net loss of $131 million as compared with net income of $1.4 billion for 2008; 
•  asset impairment charges of $604 million as compared with $294 million for 2008;  
•  $110 million loss on commodity derivative instruments (including unrealized mark-to-market loss of $606 
million) as compared with a $440 million gain on commodity derivative instruments (including unrealized 
mark-to-market gain of $522 million) for 2008; 

•  diluted loss per share of $0.75, as compared with diluted earnings per share of $7.58 for 2008;  
•  cash flows provided by operating activities of $1.5 billion, as compared with $2.3 billion in 2008; 
•  capital spending of $1.3 billion as compared with $2 billion in 2008; 
• 
issuance of $1 billion in 10-year unsecured notes; 
•  reduction of $225 million principal amount of debt; 
•  repatriation of $180 million of earnings from foreign subsidiaries; 
•  revenues of $86 million related to deepwater Gulf of Mexico royalties refund and $11 million of associated                        

interest income;  

•  year-end cash balance of $1 billion, as compared with $1.1 billion at the end of 2008;  
• 

total liquidity of $2.7 billion at December 31, 2009, consisting of year-end cash balance plus funds available 
under credit facility; and 

•  year-end ratio of debt-to-book capital of 25% as compared with 26% at December 31, 2008.

•  record Wattenberg field production of 269 MMcfepd, including liquid production of over 20 MBpd; and 
•  completion of our first horizontal East Texas Haynesville shale well with an initial thirty-day average production 

rate of over 11 MMcfpd, gross. 

International 

•  sanctioned Aseng field oil development in Block I offshore Equatorial Guinea; 
•  successful exploration well and appraisal offshore Israel at Tamar, our largest discovery to date; 
•  executed two letters of intent to sell natural gas from the Tamar field offshore Israel with expected gross 

revenues of over $10 billion; 

•  additional natural gas discovery offshore Israel at Dalit; 
•  first oil discovery on Block O offshore Equatorial Guinea at the Carmen prospect;  
•  realized record natural gas prices in Israel; and 
•  completed field optimization efforts at the Dumbarton field and brought on line the first well at Lochranza in the 

North Sea. 

In addition, we ended the year with total proved reserves of 820 MMBoe as compared with 864 MMBoe at the end of 
2008. See Proved Reserves discussion below. 

Impact of and Our Responses to the Recession and Current Credit and Commodity Markets   Our business in 
2009 was negatively impacted by the recession that began in 2008 and continues to impact the US and other world 
economies, as well as by the constraint in the credit markets and volatile commodity prices.  During late 2008 and 
2009, we took initiatives to strengthen our liquidity in response to the ongoing uncertainty.  As a result of our actions, 
described below, we believe we are in a strong financial position with approximately $2.7 billion of liquidity, consisting 
of our cash plus funds available under our credit facility, sufficient to position us to initiate execution of our long-term 
business strategy including development of our major projects and increased exploration activity.   

Debt    In February 2009 we issued $1 billion of 8¼% senior notes due 2019 and used substantially all of the net 
proceeds to repay outstanding indebtedness under our credit facility.   

At December 31, 2009, $1.7 billion was available for borrowing under our credit facility. The credit facility is 
committed in the amount of $2.1 billion until December 2011, at which time it reduces to $1.8 billion. If not extended, 
the credit facility matures in December 2012. Should current credit market conditions continue, future extensions of 
our credit facility may contain terms that are less favorable than those of the current credit facility. See Liquidity and 
Capital Resources below. 

Cash     We have over $1 billion in cash and cash equivalents invested in money market funds and short-term 
deposits with major financial institutions. During the first half of 2009, in response to the credit market crisis, we 
shortened the duration of our bank deposits and held over 50% of our cash and cash equivalents in US Treasury 
securities. We maintained this investment posture well into the third quarter of 2009 before we started to reduce our 
US Treasury holdings in favor of reinvestment back into money market funds and time deposits with highly rated 
banks.   During first quarter 2009, we repatriated $180 million of accumulated earnings of foreign subsidiaries and 
used the proceeds for debt repayment and general corporate purposes.  

We monitor the creditworthiness of the banks and financial institutions with which we invest and review the securities 
underlying our investment accounts. However, we are unable to predict sudden changes in solvency of our financial 
institutions. In the event of a bank failure, we could incur a significant loss. 

Counterparty Credit Risk   Counterparty risk related to our commodity derivative contracts and trade credit also 
increased.  All of our commodity derivative instruments are with major financial institutions.  Although our open 
commodity derivative instruments were in a net payable position at December 31, 2009, if one of these financial 
counterparties does not perform, we may not realize the benefit of some of our derivative instruments under lower 
commodity prices and we could incur a loss.   

Commodity Prices    Commodity prices continue to be volatile. Prices declined significantly during the last half of 
2008 and into 2009. During 2009, the commodities market strengthened, but our average realized prices for 2009 

36 

 
 
 
were significantly lower than average realized 2008 prices.  Lower commodity prices reduced our cash flows from 
operations as compared to prior years. To mitigate the impact of lower commodity prices on our cash flows, we 
entered into crude oil and natural gas commodity contracts for 2009, 2010 and 2011. See Item 8. Financial 
Statements and Supplementary Data – Note 6. Derivative Instruments and Hedging Activities.  If we experience a 
“double-dip” recession, a short-lived recovery followed by another recession, commodity prices could decline again, 
which would further reduce our cash flows from operations.  This may cause us to alter our business plans including 
further reduction or delay in our exploration and development program spending and/or implement other cost 
reduction and capital preservation initiatives.  See 2010 Budget below. 

Property Impairments     The significant decreases in crude oil and natural gas prices resulted in a reduction of the 
carrying values of certain of our oil and gas properties.  The commodity price decreases that began during the 
second half of 2008 required us to record asset impairment charges during fourth quarter 2008.  Further declines in 
natural gas prices during first quarter 2009 led us to review those properties that, at year-end 2008, were susceptible 
to impairment should commodity prices decline appreciably.  As a result of this review, we determined that additional 
properties were impaired as of March 31, 2009. We recorded additional impairment charges at December 31, 2009 
due to price and/or performance issues. Future declines in commodity prices could result in additional impairment of 
our oil and gas properties, other long-lived assets or goodwill. We also recorded an impairment due to a dispute in 
Ecuador regarding our natural gas-to-power project. See Item 8. Financial Statements – Note 3. Asset Impairments. 

Operating Costs   We are closely monitoring costs and have implemented several cost savings initiatives, including 
continued reduction of well costs through drilling and completion efficiencies and comprehensive review of oil and gas 
operating costs.  We are also continuing to see reductions in third-party drilling costs and operating supplies and 
services. 

OPERATING OUTLOOK 

2010 Production   We expect that we will have a modest increase in crude oil, natural gas and NGL production in 
2010 as compared with 2009 as a result of the acquisition of additional US Rocky Mountain assets scheduled to 
close first quarter 2010, and higher production in Israel and the North Sea. Our expected crude oil, natural gas and 
NGL production for 2010 may be impacted by several factors including: 

• overall level and timing of capital expenditures which, as discussed below, and dependent upon our drilling 

success, are expected to maintain our near-term production volumes;  

• natural field decline in the deepwater Gulf of Mexico, Gulf Coast and Mid-continent areas of our US operations 

and in the North Sea; 

• variations in sales volumes of natural gas from the Alba field in Equatorial Guinea related to potential 

downtime at the methanol, LPG and/or LNG plants;  

• Israeli demand for electricity which affects demand for natural gas as fuel for power generation, market growth 

and competing deliveries of natural gas from Egypt; 

• successful closing on purchase of additional US Rocky Mountain assets;  
• variations in North Sea sales volumes due to potential FPSO downtime and timing of liftings; 
• seasonal variations in rainfall in Ecuador that affect our natural gas-to-power project;  
• potential hurricane-related volume curtailments in the deepwater Gulf of Mexico and Gulf Coast areas as 

occurred with Hurricanes Gustav and Ike in 2008; 

• potential winter storm-related volume curtailments in the Northern region of our US operations; 
• potential pipeline and processing facility capacity constraints in the Rocky Mountain area of our US operations; 
• potential volume curtailments in Ecuador due to unsettled economic and political environment; 
• impact of asset purchases;  
• timing of significant project completion and initial production; and  
• impact of sales of non-core operating assets. 

2010 Budget   Our total capital investment program for 2010 is estimated at $2.5 billion, with 40% going toward 
major project investments, 20% for exploration activities, and the remaining 40% for ongoing maintenance and near-
term development opportunities.  Approximately 55% of the total is to be spent in the US with the other 45% allocated 
to international activities.    

Major project investments are expected to be about $1 billion, with the majority of capital directed toward the 
development of Galapagos in the deepwater Gulf of Mexico, Aseng offshore Equatorial Guinea, and Tamar offshore 
Israel.  Approximately $500 million is slated for exploration activities, representing our largest ever annual exploration 
program.  This program includes participation in seven high-impact offshore wells in the deepwater Gulf of Mexico, 
Equatorial Guinea and the Mediterranean Sea.  The remainder of our budget is focused on liquid-rich and emerging 
opportunities onshore in the US, as well as near-term development projects in Israel, the North Sea and China. 

Excluded from the capital budget discussed above is the $494 million we expect to pay for the DJ Basin asset 
acquisition scheduled to close in the first quarter 2010, as well as $235 million of non-cash capital expected to be 
accrued for the Aseng FPSO capital lease. 

37 

 
 
 
We expect that the 2010 budget will be funded primarily from cash flows from operations, cash on hand, and 
borrowings under our revolving credit facility and/or other financing. We will evaluate the level of capital spending 
throughout the year based on drilling results, commodity prices, cash flows from operations and property acquisitions 
and divestitures.  

Exploration Program   We have significant remaining exploration potential, primarily in the deepwater Gulf of Mexico 
and offshore Equatorial Guinea and Israel, and are planning to increase our level of exploratory activity in 2010 over 
that of 2009. We are currently engaged in drilling operations at two significant test wells in the deepwater Gulf of 
Mexico, one at the Deep Blue prospect and the second at the Double Mountain prospect, and plan to drill the 
Santiago exploratory well later in 2010. In addition, we are planning further exploratory drilling offshore Equatorial 
Guinea and another exploratory well offshore Israel, pending the outcome of a seismic program. 

Exploratory activity, particularly offshore, is expensive and requires significant capital investment. We do not always 
encounter commercially productive reservoirs through our drilling operations and, as a result, could incur significant 
dry hole cost. Dry hole cost was particularly low in 2009 as compared with prior years, due to our unprecedented 
exploratory drilling success which resulted in new discoveries in Israel, Equatorial Guinea and the deepwater Gulf of 
Mexico. This level of exploratory success will be difficult to maintain. We are planning an active exploratory drilling 
program in 2010. As a result, dry hole cost could be significant.  

Pending Asset Acquisition   On December 31, 2009, we entered into a definitive agreement to acquire substantially 
all of the US Rocky Mountain assets of Petro-Canada Resources (USA) Inc. and Suncor Energy (Natural Gas) 
America Inc. for $494 million. We estimate total proved reserves to be 53 MMBoe, 45% of which are liquids and 80% 
within the liquid-rich Wattenberg field in the Northern region of our US operations. The acquisition will add 
approximately 10 MBoepd or 46 MMcf of natural gas and 2.5 MBbls of liquids to our daily production base. The 
acquisition is expected to close late in the first quarter 2010 and is subject to customary closing conditions. Funding is 
expected to be provided through our existing credit facility.  

Major Development Project Inventory    Our current inventory of major development projects includes the Aseng oil 
project and the Galapagos oil project, both of which have been sanctioned, as well as Tamar, Gunflint, the Belinda 
cycling project, Diega/Carmen and other potential West Africa gas projects.  These projects will require significant 
capital investments.  For example, total development costs for the Aseng oil project, excluding costs related to a 
leased FPSO, are estimated at $1.3 billion ($530 million for our share). Our share of the development costs for the 
Galapagos oil project is estimated at $360 million. 

We expect to spend approximately $1 billion per year in 2010 and 2011 for major project development. We plan to 
fund these projects from cash flows from operations, cash on hand, and borrowings under our revolving credit facility 
and/or other financing such as a public debt offering. We expect first production to occur in 2011 when Galapagos 
comes on line, followed by Aseng and Tamar in 2012. Once these three projects begin producing, we expect to begin 
generating sufficient amounts of cash flow to self-fund the remaining discovered major projects investments.    

As operator on the Aseng and Tamar development projects, we pay joint venture expenses and bill our nonoperating 
partners for their respective shares of joint venture costs. This increases our counterparty credit risk substantially.   
See Impact of Recession and Current Credit and Commodity Markets – Counterparty Credit Risk, above, and Item 
1A. Risk Factors – Failure to effectively execute our major development projects could result in significant delays 
and/or cost over-runs, damage to our reputation, limitations on our growth and negative effects on our operating 
results and We are exposed to counterparty credit risk as a result of our receivables, hedging transactions, and cash 
investments.  

Growing Israel Natural Gas Realizations    During third quarter 2009, we signed a new natural gas sales contract 
with our primary customer, IEC, under the terms of which they will purchase the majority of our remaining 
undedicated Mari-B field gas at prices expected to be significantly higher than what we have been receiving under the 
original contract. The actual price received is tied to a blend of liquids prices and a producer price index.  In addition, 
it was agreed that all sales from the Mari-B field going forward will be proportionately allocated between the two 
contracts regardless of the total volume sold. This is a major change from the past arrangement wherein only 
“excess” volumes above a threshold level received premium prices. 

In addition, in fourth quarter 2009, we announced that we had signed an LOI to sell natural gas from the Tamar field, 
offshore Israel, to Dalia Power Energies (Dalia). Dalia, a privately-owned electricity company, has a license to build a 
natural gas-fired power plant in Israel with operations planned to commence in 2013. According to terms of the LOI, 
we and our partners will deliver natural gas volumes of approximately 200 Bcf to Dalia under a 17-year supply 
agreement. Total revenues for these volumes are estimated to be at least $1 billion. Sales volumes under the LOI 
may be increased to 700 Bcf depending upon the final size of the power plant and extent of operations. We also 
signed an LOI to sell natural gas from the Tamar field to IEC. IEC expects to purchase at least 95 Bcf of natural gas 
per year with the potential to procure significantly higher quantities for a period of 15 years beginning at the startup of 
Tamar. 

Potential Asset Sale   We maintain an ongoing portfolio optimization program which may result in the divestiture of 
non-core  operating  assets  in  order  to  maintain  a  balanced  portfolio  of  high-quality,  core  properties.  In  2009,  we 
conducted a market test of our wholly-owned subsidiary Noble Energy (Europe) Limited, which holds our interests in 
the Netherlands and the UK, and received bids. However, we have not committed to a plan to sell these assets. 

38 

 
Current  Conditions  in  Ecuador      The  economic  and  political  environment  in  Ecuador  has  become  increasingly 
unsettled. See Item 1A. Risk Factors – Our operations and investment in Ecuador may be adversely affected by the 
country’s unsettled economic and political environment and Item 8. Financial Statements and Supplementary Data – 
Note 3. Asset Impairments. 

Climate Change   Climate change has become the subject of an important public policy debate. While climate 
change remains a complex issue, scientific research suggests that an increase in greenhouse gas emissions (GHGs) 
may pose a risk to society and the environment. The oil and natural gas exploration and production industry is a 
source of certain GHGs, namely carbon dioxide and methane, and future restrictions on the combustion of fossil fuels 
or the venting of natural gas could have a significant impact on our future operations. We are actively monitoring the 
following climate change related issues: 

Impact of Legislation and Regulation   The commercial risk associated with the exploration and production of fossil 
fuels lies in the uncertainty of government-imposed climate change legislation, including cap and trade schemes, and 
regulations that may affect us, our suppliers, and our customers. The cost of meeting these requirements may have 
an adverse impact on our financial condition, results of operations and cash flows, and could reduce the demand for 
our products. 

Climate change legislation and regulations have been adopted by many foreign countries and states in the US; 
however, legislation and regulations have not been enacted in all of the foreign countries where we operate or at the 
federal level in the US, although Congress and several states are considering adopting climate change legislation. 
The current state of development of many state and federal climate change regulatory initiatives in areas where we 
operate makes it difficult to predict with certainty the future impact on us, including accurately estimating the related 
compliance costs that we may incur.  

Impact of International Accords   The Kyoto Protocol to the United Nations Framework Convention on Climate 
Change went into effect in February 2005 and requires all industrialized nations that ratified the Protocol to reduce or 
limit greenhouse gas emissions to a specified level by 2012. The US has not ratified the protocol. The US, Israel, and 
the European Union have participated in international discussions to develop a treaty or other agreement to require 
reductions in greenhouse gas emissions after 2012 and have indicated that they wish to associate themselves with 
the Copenhagen Accord, which includes a non-binding commitment to reduce greenhouse gas emissions.  

While no specific new international climate change accord has been adopted that would affect our operating 
locations, the current state of development of many initiatives makes it difficult to assess the timing or effect of any 
pending discussions of future accords or predict with certainty the future costs that we may incur in order to comply 
with future international treaties or regulations.   

Indirect Consequences of Regulation or Business Trends    We believe there are both risks and opportunities arising 
from the global response to climate change. See Items 1 and 2. Business and Properties – Regulation and the 
following risk factors listed in Item 1A. Risk Factors –  

•  We are subject to various governmental regulations and environmental risks that may cause us to incur 

substantial costs;  

• 

• 

Increased regulation of business practices could result in increased operating costs; and 

The adoption of pending climate change legislation could result in increased operating costs, create delays in 
our obtaining air pollution permits for new or modified facilities, and reduce demand for the crude oil and 
natural gas we produce. 

In terms of opportunities, the regulation of GHGs and introduction of formal technology incentives, such as enhanced 
oil recovery, carbon sequestration and low carbon fuel standards, could benefit us in a variety of ways. 

First, more than 60% of our 2009 production was natural gas. Climate change legislation could reduce the demand 
for the crude oil and natural gas we produce.  At the same time, the burning of natural gas produces lower levels of 
emissions than other readily available fossil fuels such as oil and coal. Therefore, the use of natural gas may increase 
should the use of other fossil fuels decrease due to climate change regulation. Furthermore, should renewable 
resources, such as wind or solar power become more prevalent, natural gas-fired electric plants may provide an 
alternative backup to maintain consistent electricity supply. 

Second, market-based incentives for the capture and storage of carbon dioxide in underground reservoirs, 
particularly in oil and natural gas reservoirs, could benefit us through the potential to obtain GHG allowances or 
offsets from or government incentives for the sequestration of carbon dioxide. 

Finally, should states adopt low-carbon fuel standards, natural gas may prove to be a more attractive transportation 
fuel. This may increase the market demand for natural gas. 

Physical Impacts of Climate Change on our Costs and Operations     There has been public discussion that climate 
change may be associated with extreme weather conditions such as more intense hurricanes, thunderstorms, 
tornados and snow or ice storms, as well as rising sea levels. Extreme weather conditions increase our costs, and 
damage resulting from extreme weather may not be fully insured. However, the extent to which climate change may 
lead to increased storm or weather hazards affecting our operations, particularly our offshore operations, is difficult to 

39 

 
identify at this time. See Item 1A. Risk Factors – We may not have enough insurance to cover all of the risks we face, 
which could result in significant financial exposure.

Factors contributing to the decrease in net income in 2009 as compared with 2008 included the following: 

•  $1.6 billion decrease in total revenues due primarily to lower commodity prices;  
•  $110 million mark-to-market loss on derivative instruments; 
•  $604 million asset impairment charges; and 
•  $25 million increase in DD&A expense; 

offset by: 

•  $86 million refund of deepwater Gulf of Mexico royalties plus interest of $11 million; 
•  $69 million decrease in total production costs; and 
•  $73 million decrease in exploration expense. 

Factors contributing to the increase in net income in 2008 as compared with 2007 included the following: 

•  $629 million increase in total revenues due primarily to higher commodity prices; and 
•  $440 million mark-to-market gain on derivative instruments; 

offset by: 

•  $294 million asset impairment charges; 
•  $106 million increase in total production costs; 
•  $55 million increase in DD&A expense; and 
•  $38 million write-down of receivable from Semcrude, L.P.  

Discontinuance of Cash Flow Hedge Accounting    Effective January 1, 2008, we discontinued cash flow hedge 
accounting on all existing commodity contracts (or “commodity derivative instruments”). We voluntarily made this 
change to simplify the accounting for our commodity hedge program as well as to add more transparency in related 
disclosures for the benefit of our investors.  From January 1, 2008 forward, we recognize all gains and losses on such 
instruments in earnings in the period in which they occur. The discontinuance of cash flow hedge accounting for 
commodity derivative instruments has no impact on our net assets or cash flows and previously reported amounts 
have not been adjusted. However, the use of mark-to-market accounting adds volatility to our net income.  

Derivative gains and losses included in net income include both pre-tax realized gains and losses and pre-tax, 
unrealized, non-cash gains or losses which are due to the change in the mark-to-market value of our commodity 
contracts related to production in future periods. Unrealized mark-to-market gains or losses recognized in the current 
period will be realized in the future when they are cash settled in the month that the related production occurs. The 
amount of gain or loss actually realized may be more or less than the amount of unrealized mark-to-market gain or 
loss previously reported. See Item 8. Financial Statements and Supplementary Data – Note 6. Derivative Instruments 
and Hedging Activities.

(1)   For 2007, US NGL sales volumes were included with natural gas volumes.  Effective in 2008, we began reporting 
US NGLs separately, which lowered the comparative natural gas sales revenues from 2007 to 2008 and 2009.

(1)   Effective in 2008, we began reporting US NGLs separately, which has lowered the comparative natural gas sales 

volumes from 2007 to 2008 and 2009. For 2007, US NGL sales volumes were included with natural gas 
volumes. 

(2)   Average realized crude oil and condensate prices reflect reductions of $2.13 per Bbl for 2009, $22.06 per Bbl for 
2008, and $13.68 per Bbl for 2007 from hedging activities. Average realized natural gas prices reflect increases 
of $0.23 per Mcf for 2008 and $1.12 per Mcf for 2007 from hedging activities. The effect of hedging activities on 
the average realized natural gas price for 2009 was de minimis. The price increases and reductions resulted 
from hedge gains and losses that had been previously deferred in accumulated other comprehensive income or 
loss (AOCL).   

(3)   Average realized crude oil and condensate prices reflect reductions of $5.57 per Bbl for 2009, $7.59 per Bbl for 
2008 and $2.19 per Bbl for 2007 from hedging activities.  The price reductions resulted from hedge losses that 
had been previously deferred in AOCL. Natural gas from the Alba field in Equatorial Guinea is under contract for 
$0.25 per MMBtu to a methanol plant, an LPG plant and an LNG plant. The methanol and LPG plants are owned 
by affiliated entities accounted for under the equity method of accounting.   

(4)   The natural gas-to-power project in Ecuador is 100% owned by our subsidiaries and intercompany natural gas 

sales are eliminated for accounting purposes. Electricity sales are included in other revenues. See Electricity 
Sales and Expense below. 

(5)   Volumes represent sales of condensate and LPG from the Alba Plant in Equatorial Guinea. See Income from 

Equity Method Investees below.

Crude Oil and Condensate Sales  

2009 Compared with 2008     Crude oil sales decreased by a net $840 million, or 40%, in 2009 as compared with 
2008. The decrease was primarily due to a 32% decline in consolidated average realized prices due to the decreased 
demand for oil. In the US, crude oil sales decreased by $359 million primarily due to lower average realized prices. 
US crude oil sales were also impacted by a 7% decline in sales volumes due to natural field decline in the deepwater 
Gulf of Mexico and Gulf Coast area and the shut-in of Ticonderoga in the deepwater Gulf of Mexico until August 2009 
after being offline due to Hurricane Ike in 2008. This decline was offset by increased production from the Wattenberg 
field in the northern region of our US operations due to ongoing development activity. Internationally, West Africa 
crude oil sales decreased by $192 million primarily due to lower average realized prices, plus a 4% decrease in 
production due to timing of liftings. In the North Sea, crude oil sales decreased by $247 million. Although the average 
realized North Sea oil price was significantly less than in 2008, the decline in sales was primarily driven by a 38% 
decline in sales volumes due to natural field decline and downtime beginning in mid-August at the Dumbarton field 
due to FPSO repairs. Crude oil sales in China decreased $42 million due to lower average realized prices. 

2008 Compared with 2007   Crude oil sales increased by a net $407 million, or 24%, in 2008 as compared with 2007. 
The increase was affected by both volume and price changes. In the US, crude oil sales increased by $286 million 
due to higher average realized prices. Sales volumes declined due to hurricane-related production shut-ins in the 
deepwater Gulf of Mexico from Hurricanes Gustav and Ike and declining production in the Gulf Coast onshore and 
Mid-continent areas of our US operations, offset by growth in the Rocky Mountain area of our US operations. 
Internationally, West Africa crude oil sales increased by $88 million due to higher average realized prices. North Sea 
crude oil sales increased by $39 million due to higher average realized prices, while sales volumes were affected by 
natural field decline. Other international crude oil sales decreased by $6 million primarily due to natural field decline in 
China. 

Hedging Gains (Losses) Included in Revenues    Crude oil sales include amounts reclassified from AOCL related to 
commodity derivative instruments which were accounted for as cash flow hedges through December 31, 2007. 
Amounts included decreases of $58 million in 2009, $365 million in 2008, and $223 million in 2007.  See Item 8. 
Financial Statements and Supplementary Data – Note 6. Derivative Instruments and Hedging Activities. 

Natural Gas Sales 

2009 Compared with 2008     Natural gas sales decreased by a net $674 million, or 49%, in 2009 as compared with 
2008. The decrease was primarily due to a 50% decline in consolidated average realized prices due to the decreased 
demand for natural gas. In the US, natural gas sales decreased by $653 million due to lower average realized prices. 
Overall, sales volumes remained about the same year to year. Increased production from the Wattenberg, Piceance 
and Western Oklahoma areas of our US operations were offset by natural field decline in the deepwater Gulf of 
Mexico, Gulf Coast and Mid-continent areas. Internationally, West Africa natural gas sales increased $3 million due to 
an increase in sales volumes. In Israel, natural gas sales decreased by $13 million. As a result of the new natural gas 
sales contract, discussed above, average realized prices in Israel increased. However, sales volumes declined 18% 
due to customer power plant downtime, warmer than normal winter weather conditions, and competing natural gas 
sales from Egypt. North Sea natural gas revenues decreased by $11 million primarily due to lower average realized 
prices. 

2008 Compared with 2007   Natural gas sales increased by a net $103 million, or 8%, in 2008 as compared with 
2007. The increase was affected by both volume and price changes. In the US, natural gas sales increased by $44 
million primarily due to higher commodity prices despite lower sales volumes. Lower volumes were the result of 
several factors including hurricane-related production shut-ins in the deepwater Gulf of Mexico from Hurricanes 
Gustav and Ike, reduction for shrink gas associated with the natural gas liquids being reported separately, and 
declining production in the Gulf Coast onshore and Mid-continent areas of our US operations. The volume decline 
was offset by a successful drilling program in the Piceance basin along with less severe winter weather in the Rocky 
Mountain area of our US operations.  Internationally, West Africa gas sales increased by $6 million from the previous 
year. Natural gas volumes were higher due to increased sales of natural gas from the Alba field in Equatorial Guinea;

however, the effect of higher production was somewhat offset by lower average realized gas prices. In Israel, natural 
gas sales increased by $44 million due to record sales volumes, which included the commencement of sales to the 
IEC power plant at Gezer, and higher average realized prices. In the North Sea, sales increased by $6 million 
primarily due to higher average realized prices. 

Hedging Gains (Losses) Included in Revenues   Natural gas revenues include amounts reclassified from AOCL 
related to commodity derivative instruments which were accounted for as cash flow hedges through December 31, 
2007.  Amounts included increases of $34 million in 2008 and $169 million in 2007.  The impact was de minimis in 
2009. See Item 8. Financial Statements and Supplementary Data – Note 6. Derivative Instruments and Hedging 
Activities. 

NGL Sales 

2009 Compared with 2008     NGL sales decreased by $77 million due to the decrease in average realized prices. 

Effective in 2008, we began reporting US NGL sales separately. This has lowered the comparative natural gas sales 
volumes and revenues from 2007 to 2008. Most of our US NGL production is from the Wattenberg field and 
deepwater Gulf of Mexico. 

Income from Equity Method Investees 

We have a 45% interest in AMPCO, which owns and operates a methanol plant and related facilities. We also have a 
28% interest in Alba Plant, which owns and operates an LPG processing plant. The plants and related facilities are 
located in Equatorial Guinea. We account for investments in entities that we do not control but over which we exert 
significant influence using the equity method of accounting.

AMPCO and Affiliates   Net income from AMPCO and affiliates decreased by $38 million, or 68%, in 2009 as 
compared with 2008 due to the significant decrease in the average realized price for methanol. The price decrease is 
a result of an oversupply of methanol and the impact of the economic slowdown. While average realized prices were 
down for the year, there was a significant increase in methanol prices during fourth quarter 2009. Methanol sales 
volumes increased as there was minimal down time for repairs as compared with 2008. 

Net income from AMPCO and affiliates decreased by $27 million, or 33%, in 2008 as compared with 2007 due to 
decreases in methanol sales volumes that resulted from 95 days of down time for compressor and other equipment 
repair and maintenance. The decreases in methanol sales volumes were offset by higher average realized methanol 
prices. 

Alba Plant   Net income from Alba Plant decreased by $52 million, or 44%, in 2009 as compared with 2008 due to 
significant decreases in average realized prices for condensate and LPG. The price decrease is a result of decreases 
in crude oil prices and the impact of the economic slowdown. While average realized prices were down for the year, 
there was a significant increase in condensate and LPG prices during fourth quarter 2009. 

Net income from Alba Plant decreased by $10 million, or 8%, in 2008 as compared with 2007 primarily due to the 
expiration of the Alba Plant tax holiday, offset by higher average realized condensate and LPG prices.

Other Revenues 

Refund of Deepwater Gulf of Mexico Royalties    We have recorded a refund of $86 million attributable to royalties 
that we previously paid on production of approximately 900 MBbls of crude oil and 3,000 MMcf of natural gas that 
was produced from January 1, 2003 through July 31, 2009 in the deepwater Gulf of Mexico. We have requested a 
refund from the MMS and anticipate receiving the monies in early 2010. Interest of $11 million related to the refund 
has been recorded in interest income. See Item 8. Financial Statements and Supplementary Data – Note 2. Summary 
of Significant Accounting Policies. 

Other   Other revenues include electricity sales and gathering, marketing and processing revenues. See Electricity 
Sales  and  Expense  below.  See  Item  8.  Financial  Statements  and  Supplementary  Data  –  Note  2.  Summary  of

(3)   Consolidated unit rates exclude sales volumes and costs attributable to equity method investees. 

Lease operating expense remained flat overall in 2009 as compared with 2008. In the US, we initiated cost savings 
initiatives which included reduced repair programs and a reduction of other discretionary spending in our onshore US 
operations, including a reduced workover program in the Northern region.  Lease operating expense increased in 
West Africa due to higher contractor costs. Lease operating expense decreased in the North Sea due to lower sales 
volumes. A higher volume of crude oil was inventoried, resulting in a deferral of production cost.  

Lease operating expense increased by $49 million, or 15%, in 2008 as compared with 2007. The increase was the 
result of higher costs related to the continuing active drilling program in the Rocky Mountains and Mid-continent areas 
of our US operations and increased workover activity in the Piceance basin, Wattenberg field, and Mid-continent and 
Gulf Coast areas of our US operations. North Sea oil and gas operating costs increased due to expanded operations 
and higher costs at the Dumbarton development.  Costs were also driven up by industry inflation resulting from the 
high level of exploration and production activities in 2008. 

Production and ad valorem tax expense decreased by $72 million, or 43%, in 2009 as compared with 2008 due to 
reduced proceeds from sales attributable to lower commodity prices in the US and China and the cessation of 
production due to the sale of our interest in Argentina in 2008. Production and ad valorem tax expense increased by 
$52 million, or 46%, in 2008 as compared with 2007 due to higher commodity prices and also by an increase in 
volumes subject to such taxes, mainly in the Northern region of our US operations. 

Transportation expense increased by $2 million, or 4%, in 2009 as compared with 2008 due to the start up of a new 
interstate crude oil transportation pipeline system used to market our Wattenberg production and offset by lower 
sales volumes in the North Sea. Transportation expense increased by $5 million, or 10%, in 2008 as compared with

development in the deepwater Gulf of Mexico. 

The unit rate of total production costs per BOE decreased for 2009 as compared with 2008 primarily due to the 
decline in production and ad valorem taxes. 

The unit rate of total production costs per BOE increased for 2008 as compared with 2007 due to rising third-party 
costs, higher production taxes and increased workover activity in the Piceance basin, Wattenberg field, and Mid-

(1)  Other international includes Ecuador, China, Argentina (through February 2008), Suriname, Cyprus, and other 

international new ventures. 

Exploration expense decreased by $73 million, or 34%, in 2009 as compared with 2008. The decrease was almost 
entirely related to the decrease in dry hole expense as a result of our recent exploration successes in the deepwater 
Gulf of Mexico, Israel and Equatorial Guinea. Dry hole expense in 2009 related primarily to an unsuccessful 
exploratory well drilled in the Northern region. 

Exploration expense was flat in 2008 as compared with 2007. Dry hole expense in 2008 related to exploratory drilling 
in Suriname ($33 million); the deepwater Gulf of Mexico ($35 million); the North Sea ($8 million); and other onshore 
US areas ($7 million).  Dry hole expense in 2007 related to a dry exploratory well in Equatorial Guinea and expense 
related to a secondary target of an exploratory well in Cameroon. 

Exploration expense included stock-based compensation expense of $9 million in 2009, $1 million in 2008 and $2 
million in 2007.

(2)   Consolidated unit rates exclude sales volumes and costs attributable to equity method investees. 

Total DD&A expense increased in 2009 as compared with 2008 due to higher production in the Wattenberg, 
Piceance and western Oklahoma areas of our US operations and ongoing capital spending in our US operations, 
offset by lower sales volumes in the North Sea.  In addition, fourth quarter 2009 DD&A was impacted by the change 
in the SEC’s pricing rules from the use of year-end prices to 12-month average prices, which resulted in negative 
reserves revisions at December 31, 2009.  This resulted in an increase in fourth quarter DD&A of approximately $16  
million. See Item 8. Financial Statements and Supplementary Data – Supplemental Oil and Gas Information 
(Unaudited) for effects of reserves revisions due to lower commodity prices at December 31, 2009. 

Total DD&A expense increased in 2008 as compared with 2007 due to several factors including higher acquisition 
and/or development costs in the Wattenberg field and other US onshore areas, negative year-end reserves revisions 
in the US due to lower commodity prices, and higher natural gas sales volumes in Israel and West Africa, offset by 
declining production in the North Sea. 

The increase in the unit rate for 2009 as compared with 2008 was due to the change in the mix of production, 
including a decrease in lower-cost volumes from Israel; ongoing capital spending in US onshore areas; and negative 
reserves revisions related to lower year-end 2009 commodity prices. 

The decrease in the unit rate for 2008 as compared with 2007 was due to a change in the mix of production.  
Increased production of lower-cost natural gas volumes from the Alba field in Equatorial Guinea and Israel were 
partially offset by increased production from areas with higher acquisition and/or development costs, such as US 
onshore areas, and negative year-end reserves revisions in the US due to lower commodity prices.

G&A expense increased by $30 million, or 15%, in 2008 as compared with 2007.  Our increased activities required 
additional personnel, which resulted in higher payroll costs.  

In addition, G&A expense is impacted by the number of stock-based awards, the market price of our common stock 
and price volatility, all of which result in a higher fair value of stock-based awards as calculated using the Black-
Scholes-Merton option pricing model. See Item 8. Financial Statements and Supplementary Data – Note 13. Stock-
based Compensation.  G&A included stock-based compensation expense of $36 million in 2009, $38 million in 2008,

The volume of natural gas produced and electric power generated in Ecuador are related to thermal electricity 
demand in Ecuador which typically declines at the onset of the rainy season. When Ecuador has sufficient rainfall to 
allow hydroelectric power producers to provide base load power, we provide electricity only to meet peak demand. As 
seasonal rains subside, we experience increasing demand for thermal electricity. 

Electricity generation expense includes all operating and non-operating expenses associated with the plant, including 
DD&A expense and changes in the allowance for doubtful accounts.  The allowance is necessary to cover potentially 
uncollectible balances related to the Ecuador power operations, as certain entities purchasing electricity in Ecuador 
have been slow to pay amounts due us. In 2009, we reduced the allowance for doubtful accounts by $46 million and 
included the amount as a reduction in electricity generation expense as a result of amounts received related to a 
settlement. We charged additions to the allowance of $14 million in 2009, $11 million in 2008, and $14 million in 
2007. See Item 8. Financial Statements and Supplementary Data – Note 2. Summary of Significant Accounting 
Policies.  
At both December 31, 2009 and 2008, we assessed the recoverability of our Ecuador investment. As a result of these 
analyses, we determined that our investment was impaired and recorded pre-tax (non-cash) impairments of $100 
million and $70 million, respectively.  See Critical Accounting Policies and Estimates – Impairment of Proved Oil and 
Gas Properties and Other Investments and Item 8. Financial Statements – Note 3.  Asset Impairments. 

(Gain) Loss on Involuntary Conversion   In 2009, we recorded a net gain of $9 million related to receipt of insurance 
claims for damage caused by Hurricanes Katrina and Rita. We recorded losses on involuntary conversion of $9 
million in 2008 and $51 million in 2007 related to hurricane damage to our Gulf of Mexico Main Pass assets. The 
amounts are included in other operating expense, net in the consolidated statements of operations. See Item 8. 
Financial Statements and Supplementary Data – Note 2. Summary of Significant Accounting Policies. 

Other    Other operating expense, net includes reductions in the carrying value of a receivable from SemCrude, L.P.,

Interest expense increased in 2009 as compared with 2008. The increase primarily relates to our $1 billion 8¼% 
senior unsecured notes due March 1, 2019, which we issued on February 27, 2009. This increase was partially offset 
by a significant decrease in credit facility interest expense due to a decline in both the average outstanding balance 
and the average interest rate.  

Interest expense decreased in 2008 as compared with 2007 due to declining interest rates applicable to our credit 
facility from 5.28% at December 31, 2007 to 0.80% at December 31, 2008, partially offset by a higher amount 
outstanding under our credit facility during 2008. See also Liquidity and Capital Resources – Financing Activities 
below.  

Interest is capitalized on exploration and development projects using an interest rate equivalent to the average rate 
paid on long-term debt. Capitalized interest is included in the cost of oil and gas assets and amortized with other 
costs on a unit-of-production basis. The majority of the capitalized interest is related to long lead-time projects in 
West Africa, the deepwater Gulf of Mexico and Israel in 2009; West Africa, deepwater Gulf of Mexico and numerous 
projects in the Rocky Mountain area in 2008; and West Africa, the North Sea and deepwater Gulf of Mexico in 2007. 
See Item 8. Financial Statements and Supplementary Data – Note 7. Capitalized Exploratory Well Costs. 

We occasionally enter into forward contracts or swap agreements to hedge exposure to interest rate risk. At 
December 31, 2009, AOCL included a deferred loss of $2 million, net of tax, related to interest rate swaps. This 
amount is being reclassified into earnings, at the rate of $0.8 million per year, as an adjustment to interest expense 
over the term of our 5¼% senior notes due 2014. See Item 8. Financial Statements and Supplementary Data – Note 
6. Derivative Instruments and Hedging Activities.

Other non-operating (income) expense, net includes deferred compensation (income) expense, interest income and 
other (income) expense, net.  

Deferred Compensation (Income) Expense   In connection with the Patina Merger in 2005, we acquired the assets 
and assumed the liabilities related to a deferred compensation plan. The assets of the deferred compensation plan 
are held in a rabbi trust and include shares of our common stock and mutual fund investments. At December 31, 
2009, approximately 45% of the market value of the assets in the rabbi trust related to our common stock. Increases 
in the market value of our common stock held in the trust result in the recognition of deferred compensation expense. 
Decreases in the market value of our common stock held in the trust result in the recognition of deferred 
compensation income. We recognized deferred compensation expense of $23 million in 2009, deferred 
compensation income of $32 million in 2008, and deferred compensation expense of $33 million in 2007. See Item 8. 
Financial Statements and Supplementary Data – Note 2. Summary of Significant Accounting Policies and Note 12. 
Benefit Plans.  

Interest Income   Interest income for 2009 includes $11 million of interest related to the refund of deepwater Gulf of 
Mexico royalties. See Item 8. Financial Statements and Supplementary Data – Note 2. Summary of Significant 
Accounting Policies. 

Income Tax Provision (Benefit)   The income tax provision (benefit) was as follows:

Our effective tax rate increased to 50% for 2009 as compared with 35% for 2008 and is the result of a tax benefit 
divided by a pre-tax loss.  In the case of a loss, our favorable permanent differences, such as income from equity 
method investees, have the effect of increasing the tax benefit which, in turn, increases the effective rate. During 
2009, we repatriated $180 million of accumulated earnings of foreign subsidiaries and used the proceeds for debt 

49 

 
        
       
      
 
 
 
repayment and general corporate purposes. The repatriation increased US tax expense by $13 million, of which $9 
million was recorded in 2008. Repatriation of additional earnings in the future could result in a decrease in our net 
income and cash flows. 

Our effective tax rate increased in 2008 compared to 2007 primarily due to the fact that pre-tax earnings increased by 
a proportionately greater amount than our excludible permanent differences.  In addition, there was a rate increase 
due to (1) a partial shift of taxable income from lower rate jurisdictions such as Equatorial Guinea and Israel to higher 
rate jurisdictions, (2) the recording of US deferred taxes on the anticipated repatriation of a portion of our foreign 
earnings, and (3) the recording of an impairment for a foreign asset on which the tax benefit was offset by a valuation 
allowance.   See Item 8. Financial Statements and Supplementary Data – Note 9. Income Taxes. 

PROVED RESERVES 

We have historically added reserves through our exploration program, development activities, and acquisitions of 
producing properties. (See Items 1. and 2.  Business and Properties). Changes in proved reserves were as follows:

Revisions     Revisions represent changes in previous reserves estimates, either upward or downward, resulting 
from new information normally obtained from development drilling and production history or resulting from a change 
in economic factors, such as commodity prices, operating costs, or development costs. Revisions at year-end 2009 
included reclassifications of proved undeveloped reserves to probable reserves as a result of the SEC’s new five year 
development rule and lower natural gas prices, partially offset by higher crude oil prices.   Revisions at year-end 2008 
were primarily due to lower year-end 2008 commodity prices. Revisions at year-end 2007 included positive revisions 
resulting from an increase in crude oil prices, additional production allowance related to LNG sales in Equatorial 
Guinea, and both positive and negative changes due to well performance.  

Extensions, Discoveries and Other Additions      These are additions to proved reserves that result from (1) 
extension of the proved acreage of previously discovered reservoirs through additional drilling in periods subsequent 
to discovery and (2) discovery of new fields with proved reserves or of new reservoirs of proved reserves in old fields. 

In 2009, US additions were primarily driven by the execution of low-risk development projects onshore in the 
Wattenberg and Piceance areas, as well as from the sanctioning of the Galapagos development in the deepwater 
Gulf of Mexico. International additions related primarily to the initial recording of reserves at the Aseng oil project in 
West Africa.  In 2008, additions were due to infill drilling activities in the Northern region of our US operations, other 
US development programs and drilling in China. In 2007, additions were due to infill drilling activities in the Northern 
region and drilling activities in the deepwater Gulf of Mexico and North Sea. 

We expect that a significant portion of future reserve additions will come from our major development projects at 
Aseng, Tamar and Gunflint; from continued drilling in the Northern region of our US operations; and from new 
discoveries resulting from our active exploration programs in the deepwater Gulf of Mexico and international 
locations. We may also purchase proved properties in strategic acquisitions.   See Operating Outlook – Major 
Development Project Inventory, above and Acquisition, Capital and Other Exploration Expenditures, below. 

Purchases     We occasionally enhance our asset portfolio with strategic acquisitions of producing properties. In 
2008 we acquired producing properties in western Oklahoma. See Operating Outlook – Pending Asset Acquisition 
and Item 8. Financial Statements and Supplementary Data – Note 4. Acquisitions and Divestitures. 

Sales   We maintain an ongoing portfolio optimization program. In 2008, we sold our Argentina asset. See Items 1. 
and 2. Business and Properties and Item 8. Financial Statements and Supplementary Data – Note 4. Acquisitions 
and Divestitures. 

Production   See Oil, Gas and NGL Sales above. 

See Operating Outlook – Pending Asset Acquisition, above, for a discussion of the pending acquisition of additional 
US Rocky Mountain assets, which we expect to add approximately 53 MMBoe of proved reserves in 2010.  See also 
Critical Accounting Policies and Estimates – Reserves, below, and Item 8. Financial Statements and Supplementary 
Data – Supplemental Oil and Gas Information (Unaudited).

LIQUIDITY AND CAPITAL RESOURCES 

Capital Structure/Financing Strategy 

In seeking to effectively fund and monetize our development and major projects pipeline, we employ a capital 
structure and financing strategy designed to provide adequate liquidity throughout the commodity price cycle.  
Specifically, we strive to retain the ability to fund long cycle capital intensive development projects while also 
maintaining the capability for financially attractive periodic mergers and acquisitions activity.  We endeavor to 
maintain an investment grade debt rating in service of these objectives.  We also utilize a commodity price hedging 
program to reduce commodity price uncertainty and enhance the predictability of cash flows along with a risk and 
insurance program to protect against disruption to our cash flows and operations. 

Traditional sources of our liquidity are cash on hand, cash flows from operations and available borrowing capacity 
under our credit facility. Occasional sales of non-strategic crude oil and natural gas properties as well as our periodic 
access to capital markets may also generate cash.

We define our ratio of debt-to-book capital as total debt (which includes both long-term debt, excluding unamortized discount, 
and short-term borrowings) divided by the sum of total debt plus shareholders’ equity.  

The ongoing disruption in the credit markets resulted in constrained access to the debt markets in the second half of 
2008 and into the first quarter of 2009. Notwithstanding these conditions, we successfully completed a debt offering in 
February 2009 and issued $1 billion of 8¼%, 10-year senior notes, utilizing the proceeds to pay down debt under our 
revolving credit facility. Since the second half of 2009, improvements in capital market conditions have increased our 
options for financing our capital requirements.  

Disruption in the credit markets also had a significant adverse impact on a number of financial institutions. We 
continue to review the creditworthiness of the banks and financial institutions with which we maintain our investments 
as well as the securities underlying our investments. Thus far, our liquidity and financial position have not been 
materially impacted. However, a recurrence of the constrained credit market conditions we experienced in late 2008 
and early 2009 could adversely affect our results of operations and cash flows.  See Executive Overview – Impact of 
Recession and Current Credit and Commodity Markets. 

Cash and Cash Equivalents   We had $1 billion in cash and cash equivalents at December 31, 2009, compared with 
$1.1 billion at December 31, 2008. At December 31, 2009, our cash was primarily denominated in US dollars and 
was invested in money market funds and short-term deposits with major financial institutions. Substantially all of this 
cash is attributable to our foreign subsidiaries and most would be subject to US income taxes if repatriated. We 
currently intend to use a majority of our international cash to fund international projects, including the development of 
our properties in West Africa and Israel.  

In fourth quarter 2008, we performed an analysis of projected short-term working capital needs as well as long-term 
capital requirements for our US and foreign operations. As a result, we repatriated $180 million of the accumulated 
earnings of foreign subsidiaries during first quarter 2009. We used the proceeds for debt repayment and general 
corporate purposes. 

Commodity Derivative Instruments   We use various derivative contracts in connection with anticipated crude oil and 
natural gas sales to minimize the impact of product price fluctuations and ensure cash flow for future capital needs. 
Such instruments include variable to fixed commodity price swaps, collars and basis swaps. 

As of December 31, 2009, we had commodity derivative assets totaling $14 million and commodity derivative 
liabilities totaling $117 million (after consideration of netting agreements). Our hedging arrangements are currently 
with a diversified group of financial institutions, substantially all of which are lenders under our credit facility 
arrangement. See Item 1A. Risk Factors – Hedging transactions may limit our potential gain and We are exposed to 
counterparty credit risk as a result of our receivables, hedging transactions, and cash investments. 

Current period settlements on commodity derivative instruments impact our liquidity, since we are either paying cash 
to, or receiving cash from, our counterparties. If actual commodity prices are higher than the fixed or ceiling prices in 
our derivative instruments, our cash flows will be lower than if we had no derivative instruments. Conversely, if actual 
commodity prices are lower than the fixed or floor prices in our derivative instruments, our cash flows will be higher 
than if we had no derivative instruments. Except for certain minor derivative contracts that are entered into from time 

51 

 
     
        
        
     
     
     
 
to time in our marketing operations, none of our counterparty agreements contain margin requirements. See 
additional information included in Critical Accounting Policies and Estimates – Derivative Instruments and Hedging 
Activities and Item 7A. Quantitative and Qualitative Disclosures About Market Risk. 

Accounts Receivable    We have accounts receivable from sales of our crude oil, natural gas and NGLs, as well as 
electricity.  We also have accounts receivable related to our joint venture partners. Some of these parties are not as 
creditworthy as we are and may experience liquidity problems. We have obtained credit enhancements from some 
parties in the way of parental guarantees or letters of credit, including our largest international crude oil purchaser; 
however, not all of our trade credit is protected through guarantees or credit support.  Nonperformance by a trade 
creditor or joint venture partner could result in losses. Other than reductions in the carrying value of a receivable from 
SemCrude, L.P., a crude oil purchaser that declared bankruptcy in 2008 and certain entities purchasing electricity in 
Ecuador, we have experienced no significant collection issues with purchasers or joint venture partners.  See Item 8.

Operating Activities   Net cash provided by operating activities totaled $1.5 billion in 2009, a decrease of $777 million, 
or 34% as compared with 2008 due primarily to decreases in sales revenues resulting from significant declines in 
commodity prices. 

Net cash provided by operating activities totaled $2.3 billion in 2008, an increase of $268 million, or 13%, as 
compared with 2007. The increase was primarily due to a significant increase in oil, gas and NGL sales resulting from 
higher average realized crude oil and natural gas prices during the first nine months of 2008. The revenue increase 
was slightly offset by higher production costs and G&A expense. Net cash provided by operating activities includes 
dividends received from equity method investees. 

Investing Activities   The primary use of cash in investing activities is for capital spending, which may be offset by 
proceeds from property sales. Net cash used in investing activities totaled $1.3 billion in 2009, as compared with $2.1 
billion in 2008. In 2009, due to the uncertain economic and commodity price environment, we designed a flexible 
capital spending program that was responsive to conditions that developed during 2009, and targeted an investment 
level of approximately $1.4 billion. Investing activities related to deepwater Gulf of Mexico lease acquisitions, 
exploratory activity in the deepwater Gulf of Mexico, Equatorial Guinea and Israel and development activity in the 
Northern region of our US operations, Equatorial Guinea and the North Sea. Net proceeds from property sales totaled 
$3 million.  

Net cash used in investing activities totaled $2.1 billion in 2008, as compared with $1.4 billion in 2007. In 2008 we 
had an expanded capital budget, with increased development, exploratory, and acquisition activity in onshore US and 
deepwater Gulf of Mexico areas as well as increased exploratory activity in international locations including Equatorial 
Guinea and Israel. Our total additions to property, plant and equipment plus acquisitions ($2.3 billion) were minimally 
offset by proceeds from property sales ($131 million). 

In comparison, in 2007, additions to property, plant and equipment totaled $1.4 billion, primarily due to development 
activity in the US and North Sea and exploratory and acquisition activities in the US and West Africa. Expenditures 
were minimally offset by proceeds from property sales of $9 million.  

Financing Activities   In 2009, net cash of $369 million was used in financing activities. We received $989 million net 
proceeds from the issuance of our 8¼% senior notes. Funds were also provided by cash proceeds from, and tax 
benefits related to, the exercise of stock options ($22 million). We made net repayments of amounts outstanding 
under our revolving credit facility ($1.2 billion), repaid an installment note ($25 million), and repurchased a portion of 
our 7¼% Senior Debentures due August 1, 2097 ($4 million). We also paid cash dividends on our common stock 
($126 million) and repurchased shares of our common stock ($1 million). 

In 2008, net cash of $327 million was provided by financing activities. We borrowed a net $426 million under our 
credit facility in support of an expanded capital budget, which included significant domestic exploration, development 
and acquisition activities and new international ventures. Funds were also provided by the cash proceeds from, and 
tax benefits related to, the exercise of stock options ($51 million). Other financing activities included the payment of 
cash dividends on our common stock ($115 million), the repayment of installment and other notes ($32 million) and 
the repurchase of stock ($3 million).

In comparison, in 2007, we used cash of $107 million in financing activities. Funds were provided by net borrowings 
($25 million) and cash proceeds from, and tax benefits related to, the exercise of stock options ($45 million). We were 
able to use available cash to finance the repurchase of two million shares of our common stock ($102 million) and 
pay cash dividends on our common stock ($75 million).

Total expenditures in 2009 decreased by $947 million, or 42%, as compared with 2008, as we reduced our capital 
spending program in response to economic conditions.  

Total expenditures in 2008 increased by $525 million, or 30%, as compared with 2007. The increase was due to 
increased development, exploratory and acquisition activity in onshore US and deepwater Gulf of Mexico areas as 
well as increased exploratory activity in international locations including Equatorial Guinea and Israel.  

Asset Sales   In February 2008, effective July 1, 2007, we sold our interest in Argentina for a sales price of $117.5 
million. 

Insurance Coverage 

Our business is subject to all of the operating risks normally associated with the exploration, production, gathering, 
processing and transportation of oil and gas, including hurricanes, blowouts, cratering and fire, any of which could 
result in damage to, or destruction of, oil and natural gas wells or formations or production facilities and other property 
and injury to persons. As protection against financial loss resulting from many, but not all of these operating hazards, 
we maintain insurance coverage, including certain physical damage, business interruption, employer’s liability, 
comprehensive general liability and worker’s compensation insurance.  We maintain insurance at levels that we 
believe are appropriate and consistent with industry practice and we regularly review our potential risks of loss and 
the cost and availability of insurance and revise our insurance program accordingly.  

We are a member in Oil Insurance Limited (OIL). OIL is a mutual insurance company which insures property, 
pollution liability, control of well and other catastrophic risks. Effective January 1, 2010, windstorm insurance 
coverage is provided subject to a $10 million per-occurrence deductible, a $150 million per-occurrence loss limit per 
member, an annual maximum of $300 million per member, and a $750 million industry aggregate per-event loss limit. 
Annual industry windstorm losses exceeding $300 million will be mutualized among windstorm members in two pools, 
one for offshore losses and one for onshore losses, with future premiums based upon a pool’s loss experience and a 
member’s weighted percent of the pool’s asset base. As a result of our recent asset retirement efforts at Main Pass, 
our risk of windstorm damage has been reduced.  We have not yet determined whether we will seek additional third-
party insurance to replace the reduction in OIL coverage. See Contractual Obligations below for a discussion of our 
theoretical withdrawal premium liability. 

For certain international locations (including Israel, Equatorial Guinea and Ecuador) we carry business interruption 
insurance for loss of revenue arising from physical damage to our facilities caused by fire and natural disasters. The 
coverage is subject to customary deductibles, waiting periods and recovery limits.

Financing Activities 

Long-Term Debt   Our long-term debt totaled $2 billion (excluding unamortized discount) at December 31, 2009, with 
maturities ranging from 2012 to 2097. Our principal source of liquidity is an unsecured revolving credit facility that 
matures December 9, 2012. The commitment is $2.1 billion until December 9, 2011 at which time the commitment 
reduces to $1.8 billion. The credit facility (i) provides for credit facility fee rates that range from 5 basis points to 15 
basis points per year depending upon our credit rating, (ii) makes available short-term loans up to an aggregate 
amount of $300 million and (iii) provides for interest rates that are based upon the Eurodollar rate plus a margin that 
ranges from 20 basis points to 70 basis points depending upon our credit rating and utilization of the credit facility. At 
December 31, 2009, $382 million in borrowings were outstanding under the credit facility, leaving $1.7 billion 
available for use. The weighted average interest rate applicable to borrowings under the credit facility at 
December 31, 2009 was 0.54%. We expect to use the credit facility to fund our planned $494 million acquisition of US 
Rocky Mountain assets in the first quarter 2010. 

The credit facility contains customary representations and warranties and affirmative and negative covenants. The 
credit facility requires that our total debt to capitalization ratio (as defined in the credit agreement), expressed as a 
percentage, not exceed 60% at any time. A violation of this covenant could result in a default under the credit facility, 
which would permit the participating banks to restrict our ability to access the credit facility and require the immediate 
repayment of any outstanding advances under the credit facility. As of December 31, 2009, we were in compliance 
with our debt covenants. 

The credit facility is with certain commercial lending institutions and its funds are available for general corporate 
purposes. Our bank group is comprised of 23 commercial lending institutions, each holding between 1.0% and 11.4% 
of the total facility.  Due to recent consolidation in the banking sector resulting from heightened stress in the credit 
markets, the number of lenders and their effective commitment levels within our credit facility may be reallocated over 
time. 

On February 27, 2009, we closed an offering of $1 billion senior unsecured notes receiving net proceeds of $989 
million, after deducting the discount and underwriting fees, and used substantially all of the net proceeds to repay 
outstanding indebtedness under our credit facility.  The notes are due March 1, 2019, and pay interest semi-annually 
at 8¼%.  

Including our new 8¼% notes, we had a total of $1.6 billion of fixed-rate debt outstanding at December 31, 2009 with 
a weighted average interest rate of 7.73%. Maturities range from 2014 to 2097.  

Credit Rating    Our senior unsecured debt is rated investment grade by both of the industry's recognized rating 
agencies.  We are currently rated Baa2/Stable Outlook from Moody's and BBB/Stable Outlook from Standard & 
Poor's.   Our latest rating action was an upgrade by Standard & Poor's in February 2009.  The ratings reflect the 
agencies' view of our positive financial metrics due to our strong liquidity and conservative financial profile.   Factors 
that could negatively pressure ratings could be driven by an overall negative industry outlook precipitated by a decline 
in oil and natural gas prices to levels that are likely to result in weak cash margins and fundamental credit 
deterioration or factors specific to us, such as deterioration in operating performance resulting in reduced cost 
competitiveness, lower capital productivity or events leading to a higher debt leverage profile in the capital structure.   
Adverse rating actions by the credit agencies would not trigger a covenant default in our credit facility or in any of our 
publicly held debt securities. 

Short-Term Borrowings   In May 2009, we made the final $25 million installment payment to the seller of properties 
we purchased in 2007. Interest on the unpaid amount was due quarterly and accrued at a LIBOR rate plus .30%. The 
interest rate was 1.51% at the date of payment. 

Our committed credit facility has been supplemented by short-term borrowings under various uncommitted credit 
lines used for working capital purposes. Uncommitted credit lines may be offered by certain banks from time to time 
at rates negotiated at the time of borrowing. There were no amounts outstanding under uncommitted credit lines at 
December 31, 2009 or 2008. Depending upon future credit market conditions, these sources may or may not be 
available. However, we are not dependent on them to fund our day-to-day operations. 

Ratio of Debt-to-Book Capital   Our ratio of debt-to-book capital was 25% at December 31, 2009 and 26% at 
December 31, 2008. Significant changes in our financial position causing a change in the ratio of debt-to-book capital 
included the following: 

•  $225 million decrease in total principal amount of debt from the balance at December 31, 2008;  

offset by: 

•  $131 million decrease in shareholders’ equity from current year net loss; and 
•  $126 million decrease in shareholders’ equity from dividends paid. 

Interest Rate Locks   We occasionally enter into forward contracts or swap agreements to hedge exposure to interest 
rate risk. As of December 31, 2007, we had entered into two interest rate locks, each in the notional amount of $500 
million. The locks were based on five and ten year US Treasury rates of 3.55% and 4.15%, respectively, and were 
scheduled to expire in September 2008. We settled the locks in July 2008 at a total cost of $0.2 million.  

54 

 
In January 2010, in anticipation of a long-term debt issuance, we entered into an interest rate forward starting swap to 
effectively fix the cash flows related to interest payments on the anticipated debt issuance. The swap is in the notional 
amount of $500 million and is based on a 30-year LIBOR swap rate. 

Cash Interest Payments   We made cash interest payments of $97 million in 2009, $109 million in 2008, and 
$122 million in 2007. 

Exercise of Stock Options   Proceeds from the exercise of stock options totaled $17 million in 2009, $27 million in 
2008, and $25 million in 2007. Proceeds received from the exercise of stock options fluctuate primarily based on the 
number of options exercised which is influenced by the price at which our common stock trades on the NYSE in 
relation to the exercise price of the options issued.  

Dividends   We paid cash dividends totaling 72 cents per common share in 2009, 66 cents per common share in 
2008, and 43.5 cents per common share in 2007. On January 26, 2010, the Board of Directors declared a quarterly 
cash dividend of 18 cents per common share, which will be paid February 22, 2010 to shareholders of record on 
February 8, 2010. The amount of future dividends will be determined on a quarterly basis at the discretion of the 
Board of Directors and will depend on earnings, financial condition, capital requirements and other factors. 

Common Stock Repurchases   We receive shares of our common stock from employees for the payment of 
withholding taxes due on the vesting of restricted shares issued under stock-based compensation plans. We received 
approximately 21,000 shares with a total value of $1 million in 2009 and approximately 33,000 shares with a total 
value of $3 million in 2008. In 2007, we completed a common stock repurchase program authorized by our Board of 
Directors in 2006 and repurchased two million shares of our common stock at an aggregate cost of $102 million. 

Off-Balance Sheet Arrangements   We may enter into off-balance sheet arrangements and transactions that can give 
rise to material off-balance sheet obligations. As of December 31, 2009, the material off-balance sheet arrangements 
and transactions that we have entered into included drilling service contracts, operating lease agreements, and 
undrawn letters of credit, all of which are customary in the oil and gas industry. Other than the off-balance sheet 
arrangements listed above, we have no transactions, arrangements or other relationships with unconsolidated entities 
or other persons that are reasonably likely to materially affect our liquidity or availability of or requirements for capital 
resources. See Contractual Obligations below for more information regarding off-balance sheet arrangements.

Instruments and Hedging Activities. 

As of December 31, 2009, we accrued approximately $28 million for an insurance contingency due to our 
membership in OIL. OIL is a mutual insurance company which insures specific property, pollution liability and other 
catastrophic risks. As part of our membership, we are contractually committed to pay termination fees should we elect 
to withdraw from OIL. We do not anticipate withdrawing from OIL; however, the potential termination fee is calculated 
annually based on OIL’s past losses and the liability reflecting this potential charge has been accrued. 

In addition, in the ordinary course of business, we maintain letters of credit in support of certain performance 
obligations of our subsidiaries. Outstanding letters of credit totaled approximately $4 million at December 31, 2009. 

Other 

Contributions to Pension and Other Postretirement Benefit Plans   We made contributions to the pension and other 
postretirement benefit plans totaling $21 million in 2009, $38 million in 2008, and $12 million in 2007. The actual 
return on plan assets was a gain of $33 million in 2009, and a loss of $43 million in 2008. The investment return has 
tended to follow market performance. In August 2006, the Pension Protection Act of 2006 (the Act) was signed into 
law. Certain provisions of this Act changed the calculation related to the maximum contribution amount deductible for 
income tax purposes and require that defined benefit pension plans become fully funded over a seven-year period 
beginning in 2008. As a result of previous contributions made to the pension plan, the plan is adequately funded at 
the balance sheet date, and we expect the plan would not be subject to any of the benefit limitations that would be 
imposed by the Act if the plan were not adequately funded.  In addition, due to the level of previous funding, we do 
not expect that there are any contributions that will be required in 2010. However, we made a contribution of $2 
million to the pension plan in January 2010 and may make additional contributions to the plan during 2010. We 
expect to make contributions pertaining to the restoration and medical and life plans of approximately $3 million 
during 2010, an amount which is estimated to be equal to the benefits expected to be paid by those plans. 

Income Taxes   We made cash payments for income taxes, net of refunds, of $227 million in 2009, $263 million in 
2008, and $149 million in 2007. 

Contingencies    Payments to settle legal proceedings totaled approximately $19 million in 2009, $2 million in 2008, 
and $56 million in 2007. We regularly analyze current information and accrue for probable liabilities on the disposition 
of certain matters, as necessary. Liabilities for loss contingencies arising from claims, assessments, litigation or other 
sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably 
estimated. 

CRITICAL ACCOUNTING POLICIES AND ESTIMATES 

The preparation of the consolidated financial statements requires our management to make a number of estimates 
and assumptions relating to the reported amounts of assets and liabilities and the disclosures of contingent assets 
and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and 
expenses during the period. When alternatives exist among various accounting methods, the choice of accounting 
method can have a significant impact on reported amounts. The following is a discussion of the accounting policies, 
estimates and judgments which management believes are most significant in the application of generally accepted 
accounting principles used in the preparation of the consolidated financial statements. 

56 

 
Reserves   All of the reserves data in this Form 10-K are estimates. Estimates of our crude oil and natural gas 
reserves are prepared by our engineers in accordance with guidelines established by the SEC, including the recent 
rule revisions designed to modernize the oil and gas company reserves reporting requirements and which we 
adopted effective December 31, 2009. Reservoir engineering is a subjective process of estimating underground 
accumulations of crude oil and natural gas. There are numerous uncertainties inherent in estimating quantities of 
proved crude oil and natural gas reserves. Uncertainties include the projection of future production rates and the 
expected timing of development expenditures. The accuracy of any reserves estimate is a function of the quality of 
available data and of engineering and geological interpretation and judgment. As a result, reserves estimates may be 
different from the quantities of crude oil and natural gas that are ultimately recovered. In addition, economic 
producibility of reserves is dependant on the oil and gas prices used in the reserves estimate. We based our 
December 31, 2009 reserves estimates on a 12-month average commodity price, unless contractual arrangements 
designate the price to be used, in accordance with SEC rules. However, oil and gas prices are volatile and, as a 
result, our reserves estimates will change in the future.  

Estimates of proved crude oil and natural gas reserves significantly affect our DD&A expense. For example, if 
estimates of proved reserves decline, the DD&A rate will increase, resulting in a decrease in net income. A decline in 
estimates of proved reserves could also cause us to perform an impairment analysis to determine if the carrying 
amount of crude oil and natural gas properties exceeds fair value and could result in an impairment charge, which 
would reduce earnings. In addition, a decline in estimates of proved reserves could prompt a goodwill impairment 
analysis. See Item 8. Financial Statements and Supplementary Data – Supplemental Oil and Gas Information 
(Unaudited). 

Oil and Gas Properties   We account for crude oil and natural gas properties under the successful efforts method of 
accounting. Under the successful efforts method, costs to acquire mineral interests in crude oil and natural gas 
properties, to drill and equip exploratory wells that find commercial quantities of proved reserves, and to drill and 
equip development wells are capitalized. Proved property acquisition costs are amortized to expense by the unit-of-
production method on a field-by-field basis based on total proved crude oil and natural gas reserves as estimated by 
our engineers. Costs to drill and equip exploratory wells that find proved reserves and to drill and equip development 
wells are also amortized to expense by the unit-of-production method on a field-by-field basis. These costs, along 
with support equipment and facilities, are amortized based on proved developed crude oil and natural gas reserves. 
Costs of certain gathering facilities or processing plants serving a number of properties or used for third-party 
processing are depreciated using the straight-line method over the useful lives of the assets. Application of the 
successful efforts method results in the expensing of certain costs including geological and geophysical costs, 
exploratory dry holes and delay rentals, during the periods the costs are incurred.  

The alternative method of accounting for crude oil and natural gas properties is the full cost method. Under the full 
cost method, geological and geophysical costs, exploratory dry holes and delay rentals are capitalized as assets and 
charged to earnings in future periods as a component of DD&A expense. In addition, under the full cost method, 
capitalized costs are accumulated in pools on a country-by-country basis. DD&A is computed on a country-by-country 
basis, and capitalized costs are limited on the same basis through the application of a ceiling test. We believe the 
successful efforts method is the most appropriate method to use in accounting for our crude oil and natural gas 
properties because it provides a better representation of results of operations, especially during periods of active 
exploration. If we had used the full cost method, our financial position and results of operations could have been 
significantly different. 

Exploratory Well Costs   In accordance with the successful efforts method of accounting, the costs associated 
with drilling an exploratory well may be capitalized temporarily, or “suspended,” pending a determination of 
whether commercial quantities of crude oil or natural gas have been discovered. We carry the costs of an 
exploratory well as an asset if the well has found a sufficient quantity of reserves to justify its completion as a 
producing well and as long as we are making sufficient progress assessing the reserves and the economic and 
operating viability of the project. For certain capital-intensive deepwater Gulf of Mexico or international projects, it 
may take several years to evaluate the future potential of the exploration well and make a determination of its 
economic viability. Our ability to move forward on a project may be dependent on gaining access to transportation 
or processing facilities or obtaining permits and government or partner approval, the timing of which is beyond our 
control. In such cases, exploratory well costs remain suspended as long as we are actively pursuing access to 
necessary facilities and access to such permits and approvals and believe they will be obtained.  

Management assesses the status of suspended exploratory well costs on a quarterly basis. These costs may be 
charged to exploration expense in future periods if we decide not to pursue additional exploratory or development 
activities. At December 31, 2009, the balance of property, plant and equipment included $432 million of suspended 
exploratory well costs, $274 million of which had been capitalized for a period greater than one year. The wells 
relating to these suspended costs continue to be evaluated by various means including additional seismic work, 
drilling additional appraisal wells to confirm the size of the hydrocarbon deposit, or evaluating the potential 
commerciality of the exploration wells. See Item 8. Financial Statements and Supplementary Data – Note 7. 
Capitalized Exploratory Well Costs. 

Impairment of Proved Oil and Gas Properties and Other Investments   We assess proved crude oil and natural 
gas properties and other investments for possible impairment when events or circumstances indicate that the 
recorded carrying value of the assets may not be recoverable. We recognize an impairment loss as a result of an 

57 

 
event that causes us to consider the possibility that impairment may have occurred and when the estimated 
undiscounted future cash flows from a property or other investment are less than the carrying value. If impairment is 
indicated, the carrying values are written down to fair value, which, in the absence of comparable market data, is 
estimated using a discounted cash flow method. In our cash flow method, cash flows are discounted using a risk-
adjusted rate and compared to the carrying value for determining the amount of the impairment loss to record. 
Estimated future cash flows are based on management’s expectations for the future and include estimates of crude 
oil and natural gas reserves and future commodity prices, revenues and operating and development costs. 
Downward revisions in estimates of reserves quantities or expectations of falling commodity prices or rising operating 
or development costs could result in a reduction in undiscounted future cash flows and could indicate property 
impairment.  

During 2009, we assessed certain proved properties for possible impairment due to lower commodity prices and/or 
performance issues. Certain assets were determined to be impaired. The impaired assets were written down to their 
estimated fair values under a discounted cash flow model. The discounted cash flow model included management’s 
estimates of future oil and gas production; commodity prices based on forward commodity price curves at the date of 
the estimate; operating and development costs, and discount rates. We also determined that our investment in 
Ecuador was impaired. 

We recorded total pre-tax (non-cash) asset impairment charges of $604 million in 2009, $219 million in 2008 and $4 
million in 2007. See Item 8. Financial Statements and Supplementary Data – Note 3. Asset Impairments.  

Impairment of Unproved Oil and Gas Properties   We also perform periodic assessments of individually significant 
unproved crude oil and natural gas properties for impairment on a quarterly basis and recognize a loss at the time of 
impairment by providing an impairment allowance. In determining whether a significant unproved property is impaired 
we consider numerous factors including, but not limited to, current exploration plans, favorable or unfavorable 
exploratory activity on the property being evaluated and/or adjacent properties, our geologists' evaluation of the 
property, and the remaining months in the lease term for the property. 

When we have allocated fair values to a significant unproved property as the result of a business combination or 
other purchase of proved and unproved properties, we use a future cash flow analysis to assess the property for 
impairment.  Cash flows used in the impairment analysis are determined based upon management’s estimates of 
natural gas and crude oil reserves, including probable and possible reserves, future commodity prices and future 
costs to extract the reserves Probable reserves are defined in SEC Regulation S-X, Rule 4-10(a)(18) as those 
additional reserves that are less certain to be recovered than proved reserves but which, together with proved 
reserves, are as likely as not to be recovered.  Possible reserves are defined in SEC Regulation S-X, 
Rule 4-10(a)(17) as those additional reserves that are less certain to be recovered than probable reserves.   

Downward revisions in estimated reserves quantities, reductions in commodity prices, or increases in estimated costs 
could cause a reduction in the value of an unproved property and, therefore, could also cause a reduction in the 
carrying amount of the property. If undiscounted future net cash flows are less than the carrying value of the property, 
indicating impairment, the cash flows are discounted using a risk-adjusted rate and compared to the carrying value 
for determining the amount of the impairment loss to record. The estimated prices used in the cash flow analysis are 
determined by management based on forward commodity price curves as of the date of the estimate, adjusted for 
average historical location and quality differentials. Estimates of cash flows related to probable and possible reserves 
are reduced by additional risk-weighting factors.  

Due to the volatility of natural gas and crude oil prices, these cash flow estimates are inherently imprecise. 
Management’s assessment of the results of exploration activities, availability of funds for future activities and the 
current and projected political climate in areas in which we operate also impact the amounts and timing of impairment 
provisions.  

We assessed the recoverability of our significant unproved oil and gas properties at December 31, 2009 and 
determined there was no impairment.  

We recorded impairments of significant unproved oil and gas properties of $75 million in 2008 and $3 million in 2007. 
See Item 8. Financial Statements and Supplementary Data – Note 3.  Asset Impairments. 

Purchase Price Allocations   As a result of the Patina Merger in 2005 and the U.S. Exploration acquisition in 2006, 
we acquired assets and assumed liabilities in transactions accounted for as purchases. In connection with a purchase 
business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and 
liabilities assumed based on fair values as of the acquisition date. Deferred taxes must be recorded for any 
differences between the assigned values and tax bases of assets and liabilities. Any excess of purchase price over 
amounts assigned to assets and liabilities is recorded as goodwill. The amount of goodwill recorded in any particular 
business combination can vary significantly depending upon the value attributed to assets acquired and liabilities 
assumed. 

In estimating the fair values of assets acquired and liabilities assumed we made various assumptions. The most 
significant assumptions related to the estimated fair values assigned to proved and unproved crude oil and natural 
gas properties. To estimate the fair values of these properties, we prepared estimates of crude oil and natural gas 
reserves. We estimated future prices to apply to the estimated reserves quantities acquired, and estimated future 

58 

 
operating and development costs, to arrive at estimates of future net cash flows. For estimated proved reserves, the 
future net cash flows were discounted using a market-based weighted average cost of capital rate determined 
appropriate at the time of the acquisition. The market-based weighted average cost of capital rate was subjected to 
additional project-specific risking factors. To compensate for the inherent risk of estimating and valuing unproved 
reserves, the discounted future net cash flows of probable and possible reserves were reduced by additional risk-
weighting factors.  

Estimated deferred taxes were based on available information concerning the tax bases of assets acquired and 
liabilities assumed and loss carryforwards at the merger date, although such estimates may change in the future as 
additional information becomes known. 

Estimated fair values assigned to assets acquired can have a significant effect on results of operations in the future. 
A higher fair value assigned to a property results in higher DD&A expense, which results in lower net earnings. Fair 
values are based on estimates of future commodity prices, reserves quantities, operating expenses and development 
costs. This increases the likelihood of impairment if future commodity prices or reserves quantities are lower than 
those originally used to determine fair value, or if future operating expenses or development costs are higher than 
those originally used to determine fair value. Impairment would have no effect on cash flows but would result in a 
decrease in net income for the period in which the impairment is recorded. 

Goodwill   As of December 31, 2009, the consolidated balance sheet included $758 million of goodwill, all of which 
has been assigned to the US reporting unit. Goodwill is not amortized to earnings but is tested, at least annually, for 
impairment at the reporting unit level. We conduct the goodwill impairment test as of December 31 of each year. 
Other events and changes in circumstances may require goodwill to be tested for impairment between annual 
measurement dates. If the carrying value of goodwill is determined to be impaired, the amount of goodwill is reduced 
and a corresponding charge is made to earnings in the period in which the goodwill is determined to be impaired. 

A two-step impairment test is used to identify potential goodwill impairment and measure the amount of a goodwill 
impairment loss to be recognized. The first step of the goodwill impairment test, used to identify potential impairment, 
compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of the reporting 
unit exceeds its carrying amount, goodwill is not considered to be impaired, and the second step of the test is not 
required.  If necessary, the second step of the impairment test, used to measure the amount of impairment loss, 
compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying 
amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in 
an amount equal to the excess. 

The first step of the impairment test requires management to make estimates regarding the fair value of the reporting 
unit to which goodwill has been assigned. In determining the fair value of the US reporting unit, we use a combination 
of the income approach and the market approach.  

Under the income approach, the fair value of the US reporting unit is estimated based on the present value of 
expected future cash flows.  The income approach is dependent on a number of factors including estimates of 
forecasted revenue and operating costs, proved reserves, as well as the success of future exploration for and 
development of unproved reserves, discount rates and other variables. Downward revisions of estimated reserves 
quantities, increases in future cost estimates, divestiture of a significant component of the reporting unit, or sustained 
decreases in natural gas or crude oil prices could lead to a reduction in expected future cash flows and possibly an 
impairment of all or a portion of goodwill in future periods.  

Key assumptions used in the discounted cash flow model described above include estimated quantities of oil and gas 
reserves, including both proved reserves and risk-adjusted unproved reserves; estimates of market prices 
considering forward commodity price curves in place as of December 31, 2009; and estimates of operating, 
administrative and capital costs adjusted for inflation. We discounted the resulting future cash flows using a peer 
company based weighted average cost of capital of 10%. 

Under the market approach, we estimated the value of the US reporting unit by comparison to similar businesses 
whose securities are actively traded in the public market. This requires management to make certain judgments 
about the selection of comparable companies and/or comparable recent company and asset transactions and 
transaction premiums. At December 31, 2009, we used a peer company multiple method for the market approach.  
Market multiples represent market estimates of fair value based on selected financial metrics. We use earnings 
before interest, taxes, DD&A and exploration expense (also known as “EBITDAX”) as our financial metric as it more 
accurately compares companies using successful efforts and full cost accounting methods, both of which are in our 
peer group.  

Using the range of US reporting unit fair values provided by the income and market approaches as of December 31, 
2009, we determined that the fair value of our US reporting unit substantially exceeded its carrying amount. 
Therefore, the second step of the goodwill impairment test was unnecessary, and no goodwill impairment was 
recognized.   

Although we have based the fair value estimate of the US reporting unit on assumptions we believe to be reasonable, 
those assumptions are inherently unpredictable and uncertain and actual results could differ from the estimate. In the 

59 

 
event of a prolonged global recession, commodity prices may stay depressed or decline further, thereby causing the 
fair value of the US reporting unit to decline, which could result in an impairment of goodwill.  

When we dispose of a reporting unit or a portion of a reporting unit that constitutes a business, we include goodwill 
associated with that business in the carrying amount of the business in order to determine the gain or loss on 
disposal. The amount of goodwill to be included in that carrying amount is based on the relative fair value of the 
business to be disposed of and the portion of the reporting unit that will be retained. The amount of goodwill allocated 
to the carrying amount of a business can significantly impact the amount of gain or loss recognized on the sale of that 
business. 

Derivative Instruments and Hedging Activities   In order to reduce commodity price uncertainty and increase cash 
flow predictability relating to the marketing of our crude oil and natural gas, we enter into crude oil and natural gas 
price hedging arrangements with respect to a portion of our expected production. In addition, we have used derivative 
instruments in connection with acquisitions and certain price-sensitive projects. Management exercises significant 
judgment in determining types of instruments to be used, production volumes to be hedged, prices at which to hedge 
and the counterparties’ creditworthiness. In accordance with US GAAP for derivative instruments and hedging 
activities, all derivative instruments are reflected at fair value in our consolidated balance sheets.  

Our open commodity derivative instruments were in a net payable position with a fair value of $103 million at 
December 31, 2009. We estimated the fair values of our commodity derivative instruments in accordance with US 
GAAP for fair value measurements. In order to determine the fair value at the end of each reporting period, we 
compute discounted cash flows for the duration of each commodity derivative instrument using the terms of the 
related contract. Inputs consist of published forward commodity price curves as of the date of the estimate. We 
compare these prices to the price parameters contained in our hedge contracts to determine estimated future cash 
inflows or outflows. We then discount the cash inflows or outflows using a combination of published LIBOR rates, 
Eurodollar futures rates and interest swap rates. The fair values of our commodity derivative assets and liabilities 
include a measure of credit risk based on current published credit default swap rates. In addition, for collars, we 
estimate the option value of the contract floors and ceilings using an option pricing model which takes into account 
market volatility, market prices and contract parameters.  We compare our estimates of fair value with those provided 
by our counterparties. There have been no significant differences.  

Changes in the fair values of our commodity derivative instruments have a significant impact on our net income 
because we follow mark-to-market accounting and recognize all gains and losses on such instruments in earnings in 
the period in which they occur. For the year ended December 31, 2009, we reported a $110 million mark-to-market 
loss on commodity derivative instruments. See Item 7. Quantitative and Qualitative Disclosures About Market Risk – 
Commodity Price Risk and Item 8. Financial Statements and Supplementary Data – Note 6. Derivative Instruments 
and Hedging Activities. 

Asset Retirement Obligations   Our asset retirement obligations (ARO) consist of estimated costs of 
dismantlement, removal, site reclamation and similar activities associated with our oil and gas properties. US 
GAAP requires that the fair value of a liability for an ARO be recognized in the period in which it is incurred with 
the associated asset retirement cost capitalized as part of the carrying cost of the oil and gas asset. The 
recognition of an ARO requires that management make numerous estimates, assumptions and judgments 
regarding such factors as the existence of a legal obligation for an ARO; estimated probabilities, amounts and 
timing of settlements; the credit-adjusted risk-free rate to be used; and inflation rates. In periods subsequent to 
initial measurement of the ARO, we recognize period-to-period changes in the liability resulting from the passage 
of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. 
Revisions also result in increases or decreases in the carrying cost of the oil and gas asset. Increases in the ARO 
liability due to passage of time impact net income as accretion expense. The related capitalized cost, including 
revisions thereto, is charged to expense through DD&A. Asset retirement obligations totaled $232 million at 
December 31, 2009. See Item 8. Financial Statements and Supplementary Data – Note 10. Asset Retirement 
Obligations. 

Involuntary Conversions   When an involuntary conversion occurs, such as the destruction of oil and gas producing 
assets by a hurricane, a loss is accrued by a charge to income if the amount of loss can be reasonably estimated. An 
asset relating to insurance recovery is recognized only when realization of the claim for recovery of a loss recognized 
in the financial statements is deemed probable. A gain (recovery of a loss not yet recognized in the financial 
statements or an amount recovered in excess of a loss recognized in the financial statements) is not recognized until 
the insurance reimbursement has been received. 

Management must make a number of estimates and assumptions relating to these gain and loss accruals. These 
include estimated costs of salvage, clean-up, restoration, redevelopment or abandonment and estimated amounts of 
insurance recoveries. The amount of an insurance recovery may be limited if total industry claims are in excess of the 
insurance carrier’s ceiling limitation per event. A significant amount of time may be necessary for an insurance carrier 
to review all related claims for an event and determine the company-specific claim limitation on the final recovery. In 
addition, we may continue to incur costs, submit claims and receive reimbursements over a multi-year period. 

The estimates involved in this process can have significant effects on reported amounts of net income. A decrease in 
the estimated amount of insurance recoveries will result in an increase in the involuntary conversion loss, which will 
result in a decrease in net income. An increase in estimated costs of salvage, if not covered by insurance, will also 

60 

 
result in an increase in the involuntary conversion loss, which will result in a decrease in net income. Unreimbursed 
losses will have a negative effect on our cash flows. During the first half of 2007, several factors contributed to an 
increase in our estimated cleanup costs for damage related to Hurricanes Ivan in 2004 and Katrina in 2005.  These 
factors included cost escalation due to weather delays and an increase in effort for the design and construction of the 
deck lifting barge and mooring system, as well as additional costs for the actual deck lifting activities.  These 
increases caused the total project costs, combined with net book value of the assets destroyed, to exceed certain 
insurance coverage limitations.  As a result, we recorded $51 million as a loss on involuntary conversion in 2007.  In 
2008, we recorded an additional $9 million loss on involuntary conversion upon resolution of certain of our insurance 
claims related to the hurricane damage sustained in 2005. In 2009, we recorded a net gain of $9 million representing 
receipt of insurance claims related to damage caused by Hurricanes Katrina and Rita. See Item 8. Financial 
Statements and Supplementary Data – Note 2. Summary of Significant Accounting Policies. 

Income Tax Expense and Deferred Tax Assets   We are subject to income and other taxes in numerous taxing 
jurisdictions worldwide. For financial reporting purposes, we provide taxes at rates applicable for the appropriate tax 
jurisdictions. Estimates of amounts of income tax to be recorded involve interpretation of complex tax laws, 
assessment of the effects of foreign taxes on domestic taxes, and estimates regarding the timing and amounts of 
future repatriation of earnings from controlled foreign corporations. 

The consolidated balance sheets include deferred tax assets. Deferred tax assets arise when expenses are 
recognized in the financial statements before they are recognized in the tax returns or when income items are 
recognized in the tax return before they are recognized in the financial statements. Deferred tax assets also arise 
when operating losses or tax credits are available to offset tax payments due in future years. Ultimately, realization of 
a deferred tax asset depends on the existence of sufficient taxable income within the future periods to absorb future 
deductible temporary differences, loss carryforwards or credits. In assessing the realizability of deferred tax assets, 
management must consider whether it is more likely than not that some portion or all of the deferred tax assets will 
not be realized. Management considers all available evidence (both positive and negative) in determining whether a 
valuation allowance is required. Such evidence includes the scheduled reversal of deferred tax liabilities, projected 
future taxable income and tax planning strategies in making this assessment, and judgment is required in considering 
the relative weight of negative and positive evidence. We continue to monitor facts and circumstances in the 
reassessment of the likelihood that operating loss carryforwards, credits and other deferred tax assets will be utilized 
prior to their expiration. As a result, we may determine, and we have determined in the past, that a deferred tax asset 
valuation allowance should be established. Any increases or decreases in a deferred tax asset valuation allowance 
would impact net income through offsetting changes in income tax expense.  

As of December 31, 2009, the accumulated undistributed earnings of our foreign subsidiaries on which no US taxes 
have been recorded totaled approximately $1.2 billion. Management must consider numerous factors in determining 
timing and amounts of possible future distribution of these earnings to the parent company and whether a US 
deferred tax liability should be recorded for these earnings. These factors include the future operating and capital 
requirements of both the parent company and the subsidiaries, remittance restrictions imposed by foreign 
governments or financial agreements and tax consequences of the remittance, including possible application of US 
foreign tax credits and limitations on foreign tax credits that may be imposed by the Internal Revenue Service (IRS) or 
IRS regulations.  

In first quarter 2009, we repatriated $180 million of accumulated earnings of foreign subsidiaries and used the 
proceeds for debt repayment and general corporate purposes. The repatriation increased US tax expense by $13 
million, of which $9 million was recorded in 2008. Repatriation of additional earnings in the future could result in a 
decrease in our net income and cash flows due to the payment of additional taxes. We currently intend to use a 
majority of our international cash to fund international projects, including the development of our properties in West 
Africa and Israel. However, we estimate that a repatriation of $1 billion as of December 31, 2009, if we had elected 
not to use the cash to fund international development, would have had a net cash tax impact of approximately $195 
million. This amount is net of estimated foreign tax credits. 

Allowance for Doubtful Accounts   We assess the recoverability of all material trade and other receivables to 
determine their collectibility on a quarterly basis. We accrue a reserve on a receivable when, based on 
management’s judgment, it is probable that a receivable will not be collected and the amount of such reserve may be 
reasonably estimated. In determining the amount of the reserve, management must analyze the aging of accounts 
receivable at the date of the consolidated financial statements and assess collectibility based on historic results, 
current collection trends and an evaluation of economic conditions. If estimates are inaccurate, we may incur gains or 
losses that could have a material effect on our results of operations. 

In 2008, we reduced the carrying value of a receivable from SemCrude, L.P., a crude oil purchaser, by $38 million. 
We reduced the carrying value by an additional $12 million in 2009 when a settlement was reached and we received 
a distribution from SemCrude. See Item 8. Financial Statements and Supplementary Data – Note 17.  Commitments 
and Contingencies.   

Through December 31, 2008, we had recorded an allowance for doubtful accounts of $57 million related to our 
Ecuador power operations. The allowance was necessary to cover potentially uncollectible balances, as certain 
entities purchasing electricity in Ecuador have been slow to pay amounts due us. As a result of pursuing various 
strategies to protect our interests, including international arbitration and litigation, we reached a settlement in fourth 

61 

 
quarter 2008. In March and April 2009, we received total payments of $60 million in accordance with the terms of the 
settlement, against which a reserve of $46 million had previously been recorded.  Accordingly, we reduced the 
allowance for doubtful accounts by $46 million and included the amount as a reduction in electricity generation 
expense in first quarter 2009.  

The allowance for doubtful accounts totaled $31 million at December 31, 2009. See Item 8. Financial Statements and 
Supplementary Data – Note 2. Summary of Significant Accounting Policies – Allowance for Doubtful Accounts. 

Benefit Plans   We sponsor a qualified defined benefit pension plan, a non-qualified defined benefit pension plan 
(restoration plan), and other postretirement benefit plans. The actuarial determination of the projected benefit 
obligations and related benefit expense requires that certain assumptions be made regarding such variables as 
expected return on plan assets, discount rates, rates of future compensation increases, estimated future employee 
turnover rates and retirement dates, distribution election rates, mortality rates, retiree utilization rates for health care 
services and health care cost trend rates. The selection of assumptions requires considerable judgment concerning 
future events and has a significant impact on the amount of the obligations recorded in the consolidated balance 
sheets and on the amount of expense included in the consolidated statements of operations. 

We base our determination of the asset return component of pension expense on a market-related valuation of 
assets, which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses 
over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the 
difference between the expected return calculated using the market-related value of assets and the actual return 
based on the fair value of assets. Since the market-related value of assets recognizes gains or losses over a five-
year period, the future value of assets will be impacted as previously deferred gains or losses are recorded. As of 
January 1, 2010, cumulative asset gains (losses) of approximately $(16) million remained to be recognized in the 
calculation of the market-related value of assets. 

In selecting the assumption for expected long-term rate of return on assets, we consider the average rate of earnings 
expected on the funds invested or to be invested to provide for plan benefits included in the projected benefit 
obligations. This includes considering the returns being earned by the plan assets and the rates of return expected to 
be available for reinvestment. We assume that the long-term asset mix will be consistent with the target asset 
allocation of 70% equity and 30% fixed income, with a range of plus or minus 10% acceptable degree of variation in 
asset allocation. A 1% decrease in the expected return on plan assets assumption would have increased 2009 net 
periodic benefit cost by approximately $2 million. The fair value of plan assets was $172 million at December 31, 
2009. The expected return assumption used in the calculation of 2009 net periodic benefit cost was 8.00%. The 
assumption will be reduced to 7.50% for the calculation of 2010 net periodic benefit cost. 

In selecting a discount rate, employers may look to rates of return on high quality fixed-income investments available 
as of the year-end measurement date and expected to be available during the period to maturity of the pension 
benefits. In order to determine an appropriate December 31, 2009 discount rate, we performed an analysis of the 
Citigroup Pension Discount Curve (the CPDC) for each of our plans. The CPDC uses spot rates that represent the 
equivalent yield on high quality, zero coupon bonds for specific maturities. We used these rates to develop an 
equivalent single discount rate based on our plans’ expected future benefit payment streams and duration of plan 
liabilities. A 1% increase in the discount rate assumption would have decreased 2009 net periodic benefit cost by 
$2 million and decreased the benefit obligation for the combined plans by $22 million at December 31, 2009. A 1% 
decrease in the discount rate assumption would have increased 2009 net periodic benefit cost by $2 million and 
increased the benefit obligation for the combined plans by $24 million at December 31, 2009. The assumed discount 
rate used to determine net periodic benefit cost for 2009 was 6.00% for the defined benefit pension and 6.25% for the 
restoration and medical and life plans. The assumed discount rate used to determine the benefit obligations at 
December 31, 2009 was 6.00% for the defined benefit pension and restoration plans and 5.50% for the medical and 
life plans. The total accrued benefit obligation for the defined benefit pension, restoration and medical and life plans 
was $251 million at December 31, 2009. 

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk 

Commodity Price Risk 

Derivative Instruments Held for Non-Trading Purposes   We are exposed to market risk in the normal course of 
business operations, and the uncertainty of crude oil and natural gas prices continues to impact the oil and gas 
industry. Due to the volatility of crude oil and natural gas prices, we continue to use derivative instruments as a 
means of managing our exposure to price changes.  

At December 31, 2009, we had entered into variable to fixed price commodity swaps, collars and basis swaps related 
to future crude oil and natural gas sales. Our open commodity derivative instruments were in a net payable position 
with a fair value of $103 million. Based on the December 31, 2009 published forward commodity price curves, a price 
increase of $1.00 per Bbl for crude oil would increase the fair value of our net commodity derivative payable by 
approximately $9 million. A price increase of $0.10 per MMBtu for natural gas would increase the fair value of our net 
commodity derivative payable by approximately $12 million.  Our derivative instruments are executed under master 
agreements which allow us, in the event of default, to elect early termination of all contracts with the defaulting 

62 

 
 
counterparty. If we choose to elect early termination, all asset and liability positions with the defaulting counterparty 
would be net settled at the time of election. See Item 8. Financial Statements and Supplementary Data – Note 6. 
Derivative Instruments and Hedging Activities. 

As of December 31, 2009, a net unrealized loss of $12 million, net of tax, is recorded in AOCL in the consolidated 
balance sheets.  We will reclassify all of the remaining deferred loss to earnings during 2010 as adjustments to 
revenue when the associated production occurs.   

Interest Rate Risk 

Changes in interest rates affect the amount of interest we pay on borrowings under our revolving credit facility and 
the amount of interest we earn on our short-term investments. 

At December 31, 2009, we had $2 billion (excluding unamortized discount) of long-term debt outstanding. Of this 
amount, $1.6 billion was fixed-rate debt with a weighted average interest rate of 7.73%. Although near-term changes 
in interest rates may affect the fair value of our fixed-rate debt, they do not expose us to the risk of earnings or cash 
flow loss.  

The remainder of our long-term debt, $382 million at December 31, 2009, was variable-rate debt. Variable-rate debt 
exposes us to the risk of earnings or cash flow loss due to increases in market interest rates. We estimate that a 
hypothetical 25 basis point change in the floating interest rates applicable to the December 31, 2009 balance of our 
variable-rate debt would result in a change in annual interest expense of approximately $1 million. 

We occasionally enter into forward contracts or swap agreements to hedge exposure to interest rate risk. Changes in 
fair value of interest rate swaps or interest rate “locks” used as cash flow hedges are reported in AOCL, to the extent 
the hedge is effective, until the forecasted transaction occurs, at which time they are recorded as adjustments to 
interest expense. At December 31, 2009, AOCL included $2 million, net of tax, related to interest rate locks. This 
amount is currently being reclassified into earnings as adjustments to interest expense over the term of our 5¼% 
Senior Notes due April 2014. See Item 8. Financial Statements and Supplementary Data – Note 6. Derivative 
Instruments and Hedging Activities. 

We are also exposed to interest rate risk related to our interest-bearing cash and cash equivalents balances. As of 
December 31, 2009, our cash and cash equivalents totaled $1 billion with investments in money market funds and 
short-term deposits with major banking institutions. A hypothetical 25 basis point change in the floating interest rates 
applicable to the amount invested as of December 31, 2009 would result in a change in annual interest income of 
approximately $2.5 million. 

Foreign Currency Risk 

The US dollar is considered the functional currency for each of our international operations. Substantially all of our 
international crude oil, natural gas and NGL production is sold pursuant to US dollar denominated contracts. 
Transactions, such as operating costs and administrative expenses that are paid in a foreign currency, are 
remeasured into US dollars and recorded in the financial statements at prevailing currency exchange rates. Certain 
monetary assets and liabilities, such as foreign deferred tax liabilities in certain foreign tax jurisdictions, are 
denominated in a foreign currency. An increase in exchange rates between the US dollar and the currency of the 
foreign tax jurisdiction in which these liabilities are located could result in the use of additional cash to settle these 
liabilities. Transaction gains or losses were not material in any of the periods presented and are included in other 
non-operating (income) expense, net in the consolidated statements of operations.  

In the UK sector of our North Sea operations, significant future capital commitments and certain operating expenses 
are expected to be denominated in British pounds and/or the Euro. Therefore, our cash flows could be impacted by 
future changes in the exchange rate between the US dollar and the British pound and/or the Euro. We currently have 
no foreign currency derivative instruments outstanding. However, we may enter into foreign currency derivative 
instruments (such as forward contracts, collars or swap agreements) in the future in order to mitigate our foreign 
currency exchange risk.

Management’s Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. 
Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer 
and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the 
preparation of consolidated financial statements for external purposes in accordance with accounting principles 
generally accepted in the United States of America. 

Because of its inherent limitations, internal control over financial reporting may not detect or prevent misstatements. 
Projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or processes may 
deteriorate. 

As of December 31, 2009, our management assessed the effectiveness of our internal control over financial reporting 
based on the criteria for effective internal control over financial reporting established in Internal Control – Integrated 
Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the 
assessment, management determined that we maintained effective internal control over financial reporting as of 
December 31, 2009, based on those criteria. Management included in its assessment of internal control over financial 
reporting all consolidated entities. 

KPMG LLP, the independent registered public accounting firm that audited our consolidated financial statements 
included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of internal control 
over financial reporting as of December 31, 2009 which is included herein.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Shareholders 
Noble Energy, Inc.: 

We have audited the accompanying consolidated balance sheets of Noble Energy, Inc. and subsidiaries as of 
December 31, 2009 and 2008, and the related consolidated statements of operations, shareholders’ equity, 
comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2009. 
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to 
express an opinion on these consolidated financial statements based on our audits. We did not audit the financial 
statements of the Alba Plant LLC (Alba), the investment in which, as discussed in Note 11 of the consolidated 
financial statements, is accounted for by the equity method of accounting. The Company’s investment in Alba at 
December 31, 2009 and 2008 was $111 million and $106 million, respectively, and its equity in earnings of Alba was 
$66 million, $118 million, and $128 million for the years ended December 31, 2009, 2008, and 2007, respectively. 
The financial statements of Alba were audited by other auditors whose reports have been furnished to us, and our 
opinion, insofar as it relates to the amounts included for Alba, is based solely on the reports of the other auditors. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the 
accounting principles used and significant estimates made by management, as well as evaluating the overall financial 
statement presentation. We believe that our audits and the reports of other auditors provide a reasonable basis for 
our opinion. 

In our opinion, based on our audits and the reports of the other auditors, the consolidated financial statements 
referred to above present fairly, in all material respects, the financial position of Noble Energy, Inc. and subsidiaries 
as of December 31, 2009 and 2008, and the results of their operations and their cash flows for each of the years in 
the three-year period ended December 31, 2009, in conformity with U.S. generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), Noble Energy, Inc.’s internal control over financial reporting as of December 31, 2009, based on criteria 
established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO), and our report dated February 18, 2010 expressed an unqualified opinion on the 
effectiveness of the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Shareholders 
Noble Energy, Inc.: 

We have audited Noble Energy, Inc.’s internal control over financial reporting as of December 31, 2009, based on 
criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO). Noble Energy, Inc.’s management is responsible for maintaining effective 
internal control over financial reporting and for its assessment of the effectiveness of internal control over financial 
reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our 
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects. Our audit included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed 
risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We 
believe that our audit provides a reasonable basis for our opinion. 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles. A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that receipts and expenditures of the company are being made 
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 
assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate. 

In our opinion, Noble Energy, Inc. maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2009, based on criteria established in Internal Control – Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the consolidated balance sheets of Noble Energy, Inc. and subsidiaries as of December 31, 2009 and 2008, 
and the related consolidated statements of operations, shareholders’ equity, comprehensive income, and cash flows 
for each of the years in the three-year period ended December 31, 2009, and our report dated February 18, 2010 
expressed an unqualified opinion on those consolidated financial statements.

Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

Note 1.  Nature of Operations 

Noble Energy, Inc. (Noble Energy, we or us) is an independent energy company engaged in worldwide crude oil, 
natural gas and natural gas liquids (NGLs) exploration and production. We operate primarily in the Rocky Mountains, 
Mid-continent, and deepwater Gulf of Mexico areas in the US, with key international operations offshore Israel and 
West Africa.   

Note 2.  Summary of Significant Accounting Policies 

Basis of Presentation and Consolidation   Accounting policies used by us and our subsidiaries conform to 
accounting principles generally accepted in the US. Significant policies are discussed below. Our consolidated 
accounts include our accounts and the accounts of our wholly-owned subsidiaries. We use the equity method of 
accounting for investments in entities that we do not control but over which we exert significant influence. We carry 
equity method investments at our share of net assets of the equity investees plus our loans and advances. 
Differences in the basis of the investment and the separate net asset value of the investee, if any, are amortized into 
income over the remaining useful life of the underlying assets. See Note 11. Equity Method Investments.  All 
significant intercompany balances and transactions have been eliminated upon consolidation. 

Use of Estimates   The preparation of consolidated financial statements in conformity with accounting principles 
generally accepted in the US (GAAP) requires us to make a number of estimates and assumptions relating to the 
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the 
consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. 

Estimates of crude oil and natural gas reserves are the most significant of our estimates. All of the reserves data in 
this Form 10-K are estimates. Reservoir engineering is a subjective process of estimating underground 
accumulations of crude oil and natural gas. There are numerous uncertainties inherent in estimating quantities of 
proved crude oil and natural gas reserves. The accuracy of any reserves estimate is a function of the quality of 
available data and of engineering and geological interpretation and judgment. As a result, reserves estimates may be 
different from the quantities of crude oil and natural gas that are ultimately recovered. Qualified petroleum engineers 
in our Houston, Denver and London offices prepare all reserves estimates for our different geographical regions. 
These reserves estimates are reviewed and approved by senior engineering staff and division management with final 
approval by the Vice President - Strategic Planning, Environmental Analysis & Reserves and certain members of 
senior management. See Supplemental Oil and Gas Information (Unaudited). 

Other items subject to estimates and assumptions include the carrying amounts of property, plant and equipment and 
goodwill, asset retirement obligations, valuation allowances for receivables and deferred income tax assets, valuation 
of derivative instruments, and obligations related to employee benefits, among others. Management evaluates 
estimates and assumptions on an ongoing basis using historical experience and other factors, including the current 
economic and commodity price environment. Current credit market conditions combined with volatile commodity 
prices have resulted in increased uncertainty inherent in such estimates and assumptions. As future events and their 
effects cannot be determined accurately, actual results could differ significantly from our estimates. 

Reclassification   Certain reclassifications have been made to the 2008 and 2007 consolidated financial statements 
to conform to the 2009 presentation. These reclassifications were not material to the financial statements. 

Property,  Plant  and  Equipment      Significant  accounting  policies  for  our  property,  plant  and  equipment  are  as 
follows: 
Successful Efforts Method   We account for crude oil and natural gas properties under the successful efforts method 
of accounting. Under this method, costs to acquire mineral interests in crude oil and natural gas properties, to drill 
and equip exploratory wells that find proved reserves and to drill and equip development wells are capitalized. 
Capitalized costs of producing crude oil and natural gas properties, along with support equipment and facilities, are 
amortized to expense by the unit-of-production method based on proved crude oil and natural gas reserves on a field-
by-field basis as estimated by our engineers. Our policy is to use quarter-end reserves and add back current period 
production to compute quarterly DD&A expense. Costs of certain gathering facilities or processing plants serving a 
number of properties or used for third-party processing are depreciated using the straight-line method over the useful 
lives of the assets ranging from five to 14 years. Upon sale or retirement of depreciable or depletable property, the 
cost and related accumulated DD&A are eliminated from the accounts and the resulting gain or loss is recognized. 
Repairs and maintenance are expensed as incurred. 

Proved Property Impairment   We review proved oil and gas properties and other long-lived assets for impairment 
when events and circumstances indicate a decline in the recoverability of the carrying value of such properties, such 
as a downward revision of the reserves estimates or sustained decrease in commodity prices. We estimate the future 
cash flows expected in connection with the properties and compare such future cash flows to the carrying amount of 
the properties to determine if the carrying amount is recoverable. When the carrying amounts of the properties 
exceed their estimated undiscounted future cash flows, the carrying amount of the properties is reduced to their 
estimated fair value. The factors used to determine fair value include, but are not limited to, estimates of proved 

73 

 
 
Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

reserves, available market data associated with the property or similar properties, future commodity prices and 
operating expenses, timing of future production, future capital expenditures and a risk-adjusted discount rate.  

Due to the declines in commodity prices which occurred during fourth quarter 2008 and continued in first quarter 
2009, we assessed the recoverability of our proved oil and gas properties and other long-lived assets and recorded 
impairment charges. Additional impairment charges were recorded at December 31, 2009. See Note 3.  Asset 
Impairments. In 2007, we recorded impairment charges of $4 million, primarily related to downward reserve revisions 
on US properties and/or adjustment of the carrying value of properties to their fair values. It is reasonably possible 
that other proved oil and gas properties or long-lived assets could become impaired in the future if commodity prices 
decline. 

Unproved Property Impairment   We assess individually significant unproved properties for impairment of value on a 
quarterly basis and recognize a loss at the time of impairment by providing an impairment allowance. In determining 
whether a significant unproved property is impaired we consider numerous factors including, but not limited to, 
current exploration plans, favorable or unfavorable exploratory activity on the property being evaluated and/or 
adjacent properties, our geologists' evaluation of the property, and the remaining months in the lease term for the 
property.  

When we have allocated fair values to a significant unproved property as the result of a business combination or 
other purchase of proved and unproved properties, we use a future cash flow analysis to assess the property for 
impairment. Cash flows used in the impairment analysis are determined based on management’s estimates of crude 
oil and natural gas reserves, future commodity prices and future costs to extract the reserves. Cash flow estimates 
related to probable and possible reserves are reduced by additional risk-weighting factors. Other individually 
insignificant unproved properties are amortized on a composite method based on our experience of successful drilling 
and average holding period.  

During fourth quarter 2008, due to declines in commodity prices, we assessed the recoverability of our individually 
significant unproved oil and gas properties and recorded impairment charges. See Note 3.  Asset Impairments. In 
2009, no impairment charges were recorded. In 2007, we recorded $3 million of impairment charges for individually 
significant unproved properties and included the amounts in exploration expense. It is reasonably possible that other 
individually significant unproved oil and gas properties could become impaired in the future if commodity prices 
decline. 

Properties Acquired in Business Combinations   In determining the fair values of proved and unproved properties 
acquired in business combinations, we prepare estimates of crude oil and natural gas reserves. We estimate future 
prices to apply to the estimated reserves quantities acquired, and estimate future operating and development costs, 
to arrive at estimates of future net cash flows. For the fair value assigned to proved reserves, the future net cash 
flows are discounted using a market-based weighted average cost of capital rate determined appropriate at the time 
of the business combination. To compensate for the inherent risk of estimating and valuing unproved reserves, the 
discounted future net cash flows of probable and possible reserves are reduced by additional risk-weighting factors. 

Exploration Costs   Geological and geophysical costs, delay rentals, amortization of unproved leasehold costs, and 
costs to drill exploratory wells that do not find proved reserves are expensed as oil and gas exploration. We carry the 
costs of an exploratory well as an asset if the well finds a sufficient quantity of reserves to justify its capitalization as a 
producing well and as long as we are making sufficient progress assessing the reserves and the economic and 
operating viability of the project. For certain capital-intensive deepwater Gulf of Mexico or international projects, it 
may take us more than one year to evaluate the future potential of the exploration well and make a determination of 
its economic viability. Our ability to move forward on a project may be dependent on gaining access to transportation 
or processing facilities or obtaining permits and government or partner approval, the timing of which is beyond our 
control. In such cases, exploratory well costs remain suspended as long as we are actively pursuing access to 
necessary facilities and access to such permits and approvals and believe they will be obtained. We assess the 
status of suspended exploratory well costs on a quarterly basis. See Note 7. Capitalized Exploratory Well Costs. 

Other Property   Other property includes automobiles, trucks, airplane, office furniture and computer equipment and 
other fixed assets such as building and leasehold improvements. These items are recorded at cost and are 
depreciated on the straight-line method based on expected lives of the individual assets or group of assets, which 
range from three to ten years. 

Capitalization of Interest   We capitalize interest costs associated with the development and construction of significant 
properties or projects to bring them to a condition and location necessary for their intended use, which for crude oil 
and natural gas assets is at first production from the field. Interest is capitalized using an interest rate equivalent to 
the average rate we pay on long-term debt, including the credit facility and bonds. Capitalized interest is included in 
the cost of oil and gas assets and amortized with other costs on a unit-of-production basis. Capitalized interest totaled 
$45 million in 2009, $33 million in 2008, and $17 million in 2007. 

Revenue Recognition and Imbalances   We record revenues from the sales of crude oil, natural gas and NGLs 
when the product is delivered at a fixed or determinable price, title has transferred and collectibility is reasonably 
assured. 

74 

 
Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

When we have an interest with other producers in properties from which natural gas is produced, we use the 
entitlements method to account for any imbalances. Imbalances occur when we sell more or less product than we are 
entitled to under our ownership percentage. Revenue is recognized only on the entitlement percentage of volumes 
sold. Any amount that we sell in excess of our entitlement is treated as a liability and is not recognized as revenue. 
Any amount of entitlement in excess of the amount we sell is recognized as revenue and a receivable is accrued. 

Revenues derived from electricity generation are recognized when power is transmitted or delivered, the price is fixed 
and determinable and collectibility is reasonably assured. 

We also engage in the purchase and sale of third-party crude oil and natural gas. We record third-party sales, net of 
cost of goods sold, as gathering, marketing and processing revenues when the product is delivered or the contract is 
net settled at a fixed or determinable price, title has transferred and collectibility is reasonably assured. Gathering, 
marketing and processing revenues are included in other revenues in the consolidated statements of operations. 

Fair Value Measurements   US GAAP for fair value measurements establishes a fair value hierarchy which 
prioritizes the inputs to valuation techniques used to measure fair value into three levels. The fair value hierarchy 
gives the highest priority to quoted market prices (unadjusted) in active markets for identical assets or liabilities (Level 
1) and the lowest priority to unobservable inputs (Level 3). Level 2 inputs are inputs, other than quoted prices 
included within Level 1, which are observable for the asset or liability, either directly or indirectly. We use Level 1 
inputs when available as Level 1 inputs generally provide the most reliable evidence of fair value. See Note 5. Fair 
Value Measurements and Disclosures. 

Derivative Instruments and Hedging Activities   In order to reduce commodity price uncertainty and increase cash 
flow predictability relating to the marketing of our crude oil and natural gas, we enter into crude oil and natural gas 
price hedging arrangements with respect to a portion of our expected production. The derivative instruments we use 
include variable to fixed price commodity swaps, collars and basis swaps. We account for derivative instruments and 
hedging activities in accordance with US GAAP for derivative instruments and hedging activities. All derivative 
instruments (including certain derivative instruments embedded in other contracts) must be recorded on the balance 
sheet as either an asset or liability measured at fair value. Changes in a derivative instrument’s fair value must be 
recognized currently in earnings unless the derivative instrument has been designated as a cash flow hedge and 
specific cash flow hedge accounting criteria are met. Under cash flow hedge accounting, unrealized gains and losses 
are reflected in shareholders’ equity as AOCL until the forecasted transaction occurs. The derivative’s gains or losses 
are then offset against related results on the hedged transaction in the statements of operations. Gains and losses 
from derivative instruments related to future crude oil and natural gas sales and which qualify for hedge accounting 
treatment are recorded in oil and gas sales in the consolidated statements of operations upon sale of the associated 
commodity. 

A company must formally document, designate and assess the effectiveness of transactions that receive hedge 
accounting. Only derivative instruments that are expected to be highly effective in offsetting anticipated gains or 
losses on the hedged cash flows and that are subsequently documented to have been highly effective can qualify for 
hedge accounting. Effectiveness must be assessed both at inception of the hedge and on an ongoing basis. Any 
ineffectiveness in hedging instruments whereby gains or losses do not exactly offset anticipated gains or losses of 
hedged cash flows is measured and recognized in earnings in the period in which it occurs. When using hedge 
accounting, we assess hedge effectiveness quarterly based on total changes in the derivative instrument’s fair value 
and using regression analysis. A hedge is considered effective if certain statistical tests are met. We record hedge 
ineffectiveness in (gain) loss on commodity derivative instruments. See Note 6. Derivative Instruments and Hedging 
Activities. 

Through December 31, 2007, we elected to designate the majority of our crude oil and natural gas derivative instruments as 
cash flow hedges. Effective January 1, 2008, we voluntarily discontinued cash flow hedge accounting on all existing 
commodity derivative instruments. We voluntarily made this change to simplify the accounting for our commodity 
hedge program as well as to add more transparency in related disclosures for the benefit of our investors.  From 
January 1, 2008 forward, we recognize all gains and losses on such instruments in earnings in the period in which they 
occur. Net derivative losses that were deferred in AOCL as of December 31, 2007, as a result of previous cash flow hedge 
accounting, are reclassified to earnings in future periods as the original hedged transactions occur. The discontinuance of cash 
flow hedge accounting for commodity derivative instruments did not affect our net assets or cash flows at December 31, 2007 
and did not require adjustments to our previously reported financial statements. 

Goodwill   Goodwill represents the excess of the cost of an acquired entity over the net amounts assigned to assets 
acquired and liabilities assumed. Goodwill is not amortized to earnings but is tested annually in the fourth quarter or 
whenever events or changes in circumstances indicate that the carrying value may not be recoverable. No goodwill 
impairment was indicated as of December 31, 2009. However, it is reasonably possible that goodwill could become 
impaired in the future if commodity prices or other economic factors become less favorable.  

We reduced the amount of goodwill originally recorded by $1 million in 2009 and $2 million in 2008 for deferred tax 
assets associated with the exercise of fully-vested stock options assumed in conjunction with the Patina Merger. 
Reductions are recorded to the extent that the stock-based compensation expense reported for tax purposes does 

75 

 
Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

not exceed the fair value of the awards recognized as part of the total purchase price. In 2010, the remainder of these 
options will expire and will no longer have an impact on our goodwill. 

Stock-Based Compensation   We recognize the grant-date fair value of stock options and other stock-based 
compensation issued to employees in the statement of operations. Expense is recognized on a straight-line basis 
over the employee’s requisite service period (generally the vesting period of the award). See Note 13. Stock-Based 
Compensation. 

Income Taxes   Income taxes are accounted for under the asset and liability method. Deferred tax assets and 
liabilities are recognized when items of income and expense are recognized in the financial statements in different 
periods than when recognized in the applicable tax return. Deferred tax assets arise when expenses are recognized 
in the financial statements before the tax returns or when income items are recognized in the tax return prior to the 
financial statements. Deferred tax assets also arise when operating losses or tax credits are available to offset tax 
payments due in future years. Deferred tax liabilities arise when income items are recognized in the financial 
statements before the tax returns or when expenses are recognized in the tax return prior to the financial statements. 
Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the 
years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets 
and liabilities of a change in tax rates is recognized in income in the period that includes the date when the change in 
the tax rate was enacted.

Refund of Deepwater Gulf of Mexico Royalties   On October 5, 2009, the US Supreme Court denied a petition filed 
by the US Department of the Interior (DOI) in a case styled Dept. of Interior, et al v. Kerr-McGee Oil and Gas Corp. 
(09-54).  This case involved the payment of royalties attributable to federal leases acquired by Kerr-McGee Oil and 
Gas Corporation (Kerr-McGee) pursuant to Section 304 of the Outer Continental Shelf Deep Water Royalty Relief Act 
of 1995 (DWRRA).  As a result of the Supreme Court’s decision, lower court rulings from the US District Court of the 
Western District of Louisiana and US Court of Appeals for the Fifth Circuit, which were in favor of Kerr-McGee, were 
left to stand.  Those courts ruled that the DOI did not have the authority to impose price thresholds that required the 
payment of royalties before minimum royalty suspension volumes imposed by Section 304 of the DWRRA were 
produced. 

Based upon our analysis of the Kerr-McGee case, we believe that the Supreme Court’s decision impacts other 
companies, including us, who were not directly involved in the case but, like Kerr-McGee, acquired leases issued 
pursuant to Section 304 of the DWRRA.  As a result, we believe that we are entitled to a refund of approximately $86 
million plus interest of $11 million. The refund is attributable to royalties that we previously paid on production of 
approximately 900 MBbls of crude oil and 3,000 MMcf of natural gas that were produced from January 1, 2003 
through July 31, 2009. We have requested a refund from the MMS and anticipate receiving the refund in 2010.

Allowance for Doubtful Accounts   We routinely assess the recoverability of all material trade and other 
receivables to determine their collectibility. We accrue a reserve on a receivable when, based on management’s 
judgment, it is probable that a receivable will not be collected and the amount of such reserve may be reasonably 
estimated. Changes in the allowance for doubtful accounts were as follows:

For a discussion of the SemCrude matter, see Note 17. Commitments and Contingencies.  

Through December 31, 2008, we had recorded an allowance for doubtful accounts of $57 million related to our 
Ecuador power operations. The allowance was necessary to cover potentially uncollectible balances, as certain 
entities purchasing electricity in Ecuador have been slow to pay amounts due us. As a result of pursuing various 
strategies to protect our interests, including international arbitration and litigation, we reached a settlement in fourth 
quarter 2008. In March and April 2009, we received total payments of $60 million in accordance with the terms of the 
settlement, against which a reserve of $46 million had previously been recorded.  Accordingly, we reduced the 
allowance for doubtful accounts by $46 million and included the amount as a reduction in electricity generation 
expense in first quarter 2009. We recorded an additional allowance of $14 million related to current period electricity 
sales in 2009. 

Inventories    Inventories consist primarily of tubular goods and production equipment used in our oil and gas 
operations and crude oil produced but not yet sold. Materials and supplies inventories are stated at the lower of 
average cost or market. The cost of crude oil inventory includes production costs and DD&A expense.

Basic and Diluted Earnings Per Share   Basic earnings per share (EPS) of our common stock have been computed 
on the basis of the weighted average number of shares outstanding during each period. The diluted EPS of  our 
common stock includes the effect of outstanding common stock equivalents. See Note 14. Earnings Per Share. 

Related Party Transactions   Following the Patina Merger in 2005, we entered into a consulting agreement with a 
former officer of Patina who now serves as a member of our Board of Directors. Pursuant to the consulting 
agreement, we reimbursed his office space rent of $42,000 in 2007.  

Contingencies   We are subject to legal proceedings, claims and liabilities that arise in the ordinary course of 
business. We accrue for losses associated with legal claims when such losses are considered probable and the 
amounts can be reasonably estimated. See Note 17. Commitments and Contingencies. 

We self-insure the medical and dental coverage provided to certain employees, certain workers’ compensation and 
the first $1 million of general liability coverage. Liabilities are accrued for self-insured claims, or when estimated 
losses exceed coverage limits, and when sufficient information is available to reasonably estimate the amount of the 
loss. 

Concentration of Market Risk   In 2009, Glencore Energy UK Ltd was the largest single non-affiliated purchaser of 
production and accounted for 25% of crude oil sales, or 16% of total oil, gas and NGL sales. In 2008, Suncor Energy 
Marketing was the largest single non-affiliated purchaser of production and accounted for 22% of crude oil sales, or 
13% of total oil, gas and NGL sales. In 2007, Marathon Petroleum Supply Company was the largest single non-
affiliated purchaser of production and accounted for 18% of crude oil sales, or 10% of total oil, gas and NGL sales. 
We believe the loss of any one purchaser would not have a material effect on our financial position or results of 
operations since there are numerous potential purchasers of our production.

Notes to Consolidated Financial Statements 

Concentration of Credit Risk   Certain of our financial instruments, including cash equivalents, trade and joint 
interest receivables and derivative instruments, may expose us to credit risk.  Substantially all of our cash at 
December 31, 2009 is located in our foreign subsidiaries. The cash is denominated in US dollars and invested in 
highly liquid money market funds and short term deposits with original maturities of three months or less at the time of 
purchase. Although our cash and cash equivalents are deposited with major international banks and financial 
institutions, concentrations of cash in certain foreign locations may increase credit risk. We monitor the 
creditworthiness of the banks and financial institutions with which we invest and review the securities underlying our 
investment accounts. We believe that losses from nonperformance are unlikely to occur; however, we are not able to 
predict sudden changes in creditworthiness. 

Our accounts receivable result  from sales of crude oil, natural gas and NGL production, and electricity, and joint 
interest billings to our partners. The receivables reflect a broad national and international customer base, which limits 
our exposure to concentrations of credit risk.  The majority of these receivables have payment terms of 30 days or 
less. We continually monitor the creditworthiness of the counterparties, some of which are not as creditworthy as we 
are and may experience liquidity problems.  We have obtained credit enhancements from some parties in the way of 
parental guarantees or letters of credit, including our largest international crude oil purchaser. However, we do not 
have all of our trade credit protected through guarantees or credit support. Nonperformance by a trade creditor could 
result in losses. In third quarter 2008, we reduced the carrying value of a receivable from SemCrude and recognized 
a pre-tax charge of $38 million for a probable loss. We recorded an additional reduction in the carrying value of the 
SemCrude receivable, and corresponding pre-tax charge, of $12 million in 2009. See Note 17. Commitments and 
Contingencies. See also Allowance for Doubtful Accounts, above, for a discussion of accounts receivable from sales 
of electricity. 

We use crude oil and natural gas derivative instruments to mitigate the effects of commodity price fluctuations and 
these derivative instruments expose us to counterparty credit risk. Our counterparties are major banks or financial 
institutions. Our derivative instruments are executed under master agreements which allow us, in the event of default, 
to elect early termination of all contracts with the defaulting counterparty. If we choose to elect early termination, all 
asset and liability positions with the defaulting counterparty would be net settled at the time of election.  

We monitor the creditworthiness of our counterparties. However, we are not able to predict sudden changes in 
counterparties’ creditworthiness. In addition, even if such changes are not sudden, we may be limited in our ability to 
mitigate an increase in counterparty credit risk. Possible actions would be to transfer our position to another 
counterparty or request a voluntary termination of the derivative contracts resulting in a cash settlement. Should one 
of these financial counterparties not perform, we may not realize the benefit of some of our derivative instruments 
under lower commodity prices as well as incur a loss. See Note 6. Derivative Instruments and Hedging Activities. 

Treasury Stock   We record treasury stock purchases at cost, which includes incremental direct transaction costs. 
Amounts are recorded as reductions in shareholders’ equity. 

Foreign Currency   The US dollar is considered the functional currency for each of our international operations. 
Transactions that are completed in foreign currencies are remeasured into US dollars and recorded in the financial 
statements at prevailing foreign exchange rates. Transaction gains or losses were not material in any of the periods 
presented and are included in other non-operating (income) expense, net in the consolidated statements of 
operations. 

Recently Adopted Standards The following standards have been adopted: 

Recent SEC Rule-Making Activity   In December 2008, the SEC announced that it had approved revisions designed 
to modernize the oil and gas company reserves reporting requirements. The most significant amendments to the 
requirements included the following: 

•  Commodity Prices – Economic producibility of reserves and discounted cash flows is now based on a 12-
month average commodity price unless contractual arrangements designate the price to be used. 

•  Disclosure of Unproved Reserves – Probable and possible reserves may be disclosed separately on a 

voluntary basis. 

•  Proved Undeveloped Reserves Guidelines – Reserves may be classified as proved undeveloped if there is a 
high degree of confidence that the quantities will be recovered and they are scheduled to be drilled within 
the next five years. 

•  Reserves Estimation Using New Technologies – Reserves may be estimated through the use of reliable 

technology in addition to flow tests and production history. 

•  Reserves Personnel and Estimation Process – Additional disclosure is required regarding the qualifications 
of the chief technical person who oversees the reserves estimation process.  We are also required to 
provide a general discussion of our internal controls used to assure the objectivity of the reserves estimate. 

80 

 
 
Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

•  Disclosure by Geographic Area – Reserves in foreign countries or continents must be presented separately 

if they represent more than 15% of our total oil and gas proved reserves. 

•  Non-Traditional Resources – The definition of oil and gas producing activities has expanded and focuses on 

the marketable product rather than the method of extraction. 

We adopted the rules effective December 31, 2009. See Supplemental Oil and Gas Information (Unaudited) for 
impact of adoption on oil and gas reserves.  

In addition, in January 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 
(Update) 2010-03, “Oil and Gas Reserve Estimation and Disclosures”, to provide consistency with the new SEC 
rules. The Update amends existing standards to align the reserves calculation and disclosure requirements under US 
GAAP with the requirements in the SEC rules. We adopted the new standards effective December 31, 2009. The new 
standards are applied prospectively as a change in estimate. See also Supplemental Oil and Gas Information 
(Unaudited). 

Postretirement Benefit Plan Asset Disclosures   In December 2008, the FASB issued new standards which require 
employers to make additional disclosures about plan assets for defined benefit pension and other postretirement 
benefit plans beginning with annual periods ending after December 15, 2009. Disclosures must provide an 
understanding of how investment allocation decisions are made, the major categories of plan assets, the inputs and 
valuation techniques used to measure the fair value of plan assets, the effect of fair-value measurements using 
significant unobservable inputs on changes in plan assets for the period, and significant concentrations of risk within 
plan assets. We adopted the new standards as of December 31, 2009. Adoption of the new standards had no impact 
on our financial position or results of operations.  See Note 12. Benefit Plans. 

Business Combinations and Noncontrolling Interests in Consolidated Financial Statements   In 2007, the FASB 
issued new standards regarding the accounting for business combinations and noncontrolling interests in 
consolidated financial statements. These standards require most identifiable assets, liabilities and noncontrolling 
interests to be recorded at full fair value and require noncontrolling interests to be reported as a component of equity. 
We adopted the new standards as of January 1, 2009. There were no non-controlling interests at adoption date. 
Adoption of the new standards had no impact on our financial position or results of operations. 

Fair Value Measurements   The FASB’s fair value measurement standards establish a single authoritative definition 
of fair value based upon the assumptions market participants would use when pricing an asset or liability and create a 
fair value hierarchy that prioritizes the information used to develop those assumptions. The standards require 
additional disclosures, including disclosures of fair value measurements by level within the fair value hierarchy. As of 
January 1, 2008, we adopted the new standards as they related to our financial assets and liabilities. As of January 1, 
2009, we adopted the new standards as they related to our nonfinancial assets and liabilities, including nonfinancial 
assets and liabilities measured at fair value in a business combination; impaired property, plant and equipment; 
goodwill impairment; and initial recognition of asset retirement obligations. Adoption of the new standards did not 
have a significant impact on our consolidated financial statements.  

In April 2009, the FASB issued additional guidance clarifying the application of US GAAP for fair value measurements 
in the current economic environment, modifying the recognition of other-than-temporary impairments of debt 
securities, and requiring companies to disclose the fair value of financial instruments in interim periods. The revised 
guidance was effective for interim and annual periods ending after June 15, 2009. The guidance: 

 • describes how to determine the fair value of assets and liabilities in the current economic environment and 

reemphasizes that the objective of a fair value measurement remains the price that would be received to sell 
an asset or paid to transfer a liability at the measurement date;       

•  modifies the requirements for recognizing other-than-temporarily impaired debt securities and significantly 
changes the existing impairment model for such securities. It also modifies the presentation of other-than-
temporary impairment losses and increases the frequency of and expands already required disclosures about 
other-than-temporary impairment for debt and equity securities; and  

•  requires disclosures of the fair value of financial instruments in interim financial statements, the method or 

methods and significant assumptions used to estimate the fair value of financial instruments, and a discussion 
of changes, if any, in the method or methods and significant assumptions during the period.    

We adopted this new guidance for the quarter ended June 30, 2009. Adoption of the new guidance had no impact on 
our financial position or results of operations.  

In August 2009, the FASB issued Accounting Standards Update 2009-5, “Measuring Liabilities at Fair Value” in order 
to provide further guidance on how to measure the fair value of a liability. The Update clarifies that, in circumstances 
in which a quoted price in an active market for the identical liability is not available, a reporting entity is required to 
measure fair value using one or more prescribed techniques. We adopted the new guidance as of October 1, 2009. 
Adoption of the new guidance had no impact on our financial position or results of operations. 

81 

 
 
Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

See Note 5. Fair Value Measurements and Disclosures. 

Fair Value Option   Under US GAAP for fair value measurements, companies have an option to report selected 
financial assets and liabilities at fair value. We adopted the new guidance for optional fair value measurements as of 
January 1, 2008. Adoption of the new guidance had no effect on our financial position or results of operations as we 
made no elections to report selected financial assets or liabilities at fair value. 

Derivative Instruments and Hedging Activities   In March 2008, the FASB issued new standards which amended and 
expanded previous disclosure requirements related to derivative instruments and hedging activities. The new 
standards require qualitative disclosures about objectives and strategies for using derivative instruments, quantitative 
disclosures about fair value amounts of derivative instruments and related gains and losses, and disclosures about 
credit risk-related contingent features in derivative agreements. We adopted the new standards as of January 1, 
2009. They provide only for enhanced disclosures, and adoption of the new standards had no impact on our financial 
position or results of operations. See Note 6. Derivative Instruments and Hedging Activities. 

Subsequent Events   In May 2009, the FASB issued new standards which establish the accounting for and disclosure 
of events that occur after the balance sheet date but before financial statements are issued. In particular, the new 
standards set forth: 

•  the period after the balance sheet date during which management of a reporting entity should evaluate events 
or transactions that may occur for potential recognition or disclosure in the financial statements (through the 
date that the financial statements are issued or are available to be issued); 

•  the circumstances under which an entity should recognize events or transactions occurring after the balance 

sheet date in its financial statements; and 

•  the disclosures that an entity should make about events or transactions that occurred after the balance sheet 

date. 

We adopted the new standards as of June 30, 2009. We have evaluated subsequent events after the balance sheet 
date of December 31, 2009 through the time of filing with the SEC on February 18, 2010, which is the date the 
financial statements were issued. See Note 4. Acquisitions and Divestitures – Pending Asset Acquisition and Note 6. 
Derivative Instruments and Hedging Activities – Interest Rate Hedges. 

Accounting Standards Codification   In June 2009, the FASB established the FASB Accounting Standards 
Codification (Codification), which officially commenced July 1, 2009, to become the source of authoritative US GAAP 
recognized by the FASB to be applied by nongovernmental entities.  Rules and interpretive releases of the SEC 
under authority of federal securities laws are also sources of authoritative US GAAP for SEC registrants.  Generally, 
the Codification is not expected to change US GAAP.  All other accounting literature excluded from the Codification 
will be considered nonauthoritative.  The Codification is effective for financial statements issued for interim and 
annual periods ending after September 15, 2009.  We adopted the new standards for our quarter ending September 
30, 2009.  All references to authoritative accounting literature are now referenced in accordance with the Codification. 

Equity Method Investments   In November 2008, the FASB issued new guidance in accounting for equity method 
investments. The new guidance was issued to address questions that arose regarding the application of the equity 
method subsequent to the issuance of new business combination standards. The new guidance concluded that 
equity method investments should continue to be recognized using a cost accumulation model, thus continuing to 
include transaction costs in the carrying amount of the equity method investment. In addition, it clarified that an 
impairment assessment should be applied to the equity method investment as a whole, rather than to the individual 
assets underlying the investment. We adopted the new guidance as of January 1, 2009. Adoption of the new 
guidance had no impact on our financial position or results of operations. 

Offsetting of Amounts Related to Certain Contracts    As of January 1, 2008 we adopted guidance allowing 
companies to offset fair value amounts recognized for derivative instruments and the fair value amounts recognized 
for the right to reclaim cash collateral or the obligation to return cash collateral. The cash collateral (commonly 
referred to as a “margin”) must arise from derivative instruments recognized at fair value that are executed with the 
same counterparty under a master netting arrangement. Upon adoption of the new guidance, we elected to offset the 
right to reclaim cash collateral or the obligation to return cash collateral against our net derivative positions for which 
master netting agreements exist. As of December 31, 2009 and 2008, we had no significant cash collateral 
obligations. 

Accounting for Uncertainty in Income Taxes   As of January 1, 2007, we adopted new standards which clarified the 
accounting for uncertainty in income taxes recognized in a company’s financial statements. The new standards 
prescribed a recognition threshold and measurement attribute for the financial statement recognition and 
measurement of a tax position taken or expected to be taken in a tax return. They also provided guidance on 
derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Also as 
of January 1, 2007, we adopted related guidance regarding the definition of “settlement”. This guidance provided that 
a company’s tax position will be considered settled if the taxing authority has completed its examination, the company 
does not plan to appeal, and it is remote that the taxing authority would reexamine the tax position in the future.

Note 3.  Asset Impairments 

2009 Asset Impairments    Pre-tax (non-cash) impairments for 2009 totaled $604 million and related to the following 
proved oil and gas properties and investments: 

•  $389 million related to Granite Wash, an onshore US development;  
•  $48 million related to Main Pass, our remaining operated Gulf of Mexico shelf asset; 
•  $44 million related to Paxton, an onshore US development;  
•  $23 million related to Raton, a deepwater Gulf of Mexico development; and 
•  $100 million related to our investment in Ecuador.  

US Oil and Gas Assets    As a result of a significant decline in the forward natural gas price curve at March 31, 2009, 
we reviewed our oil and gas properties that are sensitive to natural gas price decreases for impairment. We 
determined that the carrying amount of Granite Wash, an onshore US area where we have significantly reduced 
investments beginning in 2007, was not recoverable from future cash flows and, therefore, was impaired at March 31, 
2009.  We reduced Granite Wash to its fair value, using a discounted cash flow method, as comparable market data 
was not available.  We also impaired our Main Pass asset in the Gulf of Mexico, which had been reclassified from 
held-for-sale to held-and-used.  

At December 31, 2009, we reviewed our significant properties for impairment and recorded impairment charges on 
two additional properties.  We determined that Paxton, an onshore US development was impaired primarily due to 
decreases in the forward natural gas price curve.  We also impaired Raton, a deepwater Gulf of Mexico development 
primarily due to well performance issues.  We reduced these properties to their fair values, using a discounted cash 
flow method, as comparable market data was not available.   

Our US proved properties (including our Main Pass asset) were tested for impairment in 2009 in accordance with US 
GAAP for impairment or disposal of long-lived assets. The assets were written down to their estimated fair values 
which were determined using discounted cash flow models. The discounted cash flow models included 
management’s estimates of future oil and gas production, commodity prices based on forward commodity price 
curves as of the date of the estimate, operating and development costs, and discount rates. 

Investment in Ecuador    As a result of the increasingly unsettled economic and political environment in Ecuador, we 
also reviewed our investment in Ecuador for impairment as of December 31, 2009. We are aware that the 
Government of Ecuador is taking steps to renegotiate contracts or, in some cases, remove international oil and gas 
companies from its borders.  In recent years, certain international companies have been subject to expropriation, 
forced to abandon their oil and gas assets, or bought out of their government contracts.  On August 24, 2009, 
Ecuador’s National Bureau of Hydrocarbons (DNH) rejected our third and most recent proposed plan of development 
for the Amistad field in Block 3, offshore Ecuador and noted that it was treating the plan of development as if it had 
not been received.  We appealed the decision of the DNH, and it dismissed our appeal on November 11, 2009.  On 
November 12, 2009, Empresa Estatal Petroleos Del Ecuador (Petroecuador) initiated the procedure of caducidad (or 
termination) by providing us with a notice that alleged 15 instances of non-compliance with the production sharing 
contract for Block 3 (PSC).  On November 24, 2009, we responded to Petroecuador noting that its allegations had 
previously been resolved in our favor or otherwise addressed.  Nevertheless, on December 31, 2009, Petroecuador 
requested that Ecuador’s Minister of Non-Renewable Natural Resources commence termination of the PSC on the 
basis of the foregoing allegations and because a plan of development had not been approved. On February 11, 2010, 
the Minister notified us of Petroecuador’s request, by delivering to us a copy of a letter of non-compliance dated 
December 31, 2009.  The Minister provided us with 60 business days to respond to the allegations contained in the 
letter.  We intend to vigorously act to protect our interests, and are evaluating appropriate action.  

We determined that the carrying value of our investment in Ecuador exceeded its fair value by $100 million and we 
recorded an impairment charge for this amount in fourth quarter 2009. At December 31, 2009, we estimated the fair 
value of our investment in Ecuador using a probability-weighted discounted cash flow model that considered the 
likelihood of possible outcomes of (1) the event of continued operation of the assets in contemplation of resolving the 
dispute and in accordance with the existing contract, (2) the event of a sale of our investment to a third party, and (3) 
the event of arbitration with varying degrees of award and collection. The use of alternative judgments and/or 
assumptions could have resulted in the recognition of an impairment charge that was significantly different.  Future 
estimates of fair value may change, which could result in additional impairment charges.  Our investment in Ecuador 
had a net book value of approximately $72 million after the December 31, 2009 impairment. 

See also Note 5. Fair Value Measurements. 

2008 Asset Impairments   As a result of the depressed economic environment, coupled with a severe decrease in 
commodity prices during the fourth quarter of 2008, we assessed the recoverability of our proved and unproved oil 
and gas properties and other investments as of December 31, 2008. As a result, we determined that certain of our 
assets were impaired. In addition, during third quarter 2008, we recorded an impairment charge related to our Main 

83 

 
 
Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

Pass asset based on anticipated sales proceeds less costs to sell. Total pre-tax (non-cash) impairment charges for 
2008 were $294 million, as follows:   

•  $111 million related to various US proved oil and gas properties; 
•  $70 million related to our investment in Ecuador; 
•  $75 million related to various US unproved properties; and 
•  $38 million related to the Main Pass asset held for sale. 

The impairments of unproved US oil and gas properties in 2008 were primarily related to allocated fair values 
attributable to probable and possible reserves acquired in previous business combinations. We assessed these 
properties using discounted cash flow models based on management’s assumptions of future production, commodity 
prices, operating and development costs, and discount rates.   

Our US proved properties and investment in Ecuador were tested for impairment in 2008 in accordance with US 
GAAP for impairment or disposal of long-lived assets. The assets were written down to their estimated fair values 
which were determined using discounted cash flow models. The discounted cash flow models included 
management’s estimates of future oil and gas production, commodity prices based on forward commodity price 
curves as of the date of the estimate, operating and development costs, and discount rates.  

Note 4.  Acquisitions and Divestitures 

Mid-continent Acquisition   In July 2008, we acquired producing properties in western Oklahoma for $292 million. The 
total purchase price was allocated to the proved and unproved properties acquired based on fair values at the 
acquisition date. Approximately $254 million was allocated to proved properties and $38 million to unproved 
properties. 

Sale of Argentina Assets   In February 2008, effective July 1, 2007, we sold our interest in Argentina for a sales price 
of $117.5 million. The sale was subject to Argentine government approval. The $24 million gain on sale was deferred 
in other current liabilities until second quarter 2009 when the Argentine government approved the sale. 

Main Pass Asset   In 2008, we initiated a process to sell our remaining operated non-core Gulf of Mexico shelf asset 
located at Main Pass. Numerous parties expressed an interest in purchasing the asset. However, due to difficulties in 
obtaining appropriate insurance, bonding or financing, none of the potential buyers were able to close on the sale. As 
a result, the asset was reclassified from held-for-sale to held-and-used in first quarter 2009.  Due to significant 
increases in insurance costs and exposure to further windstorm damage, we are in the process of abandoning the 
Main Pass asset.  See Note 3.  Asset Impairments.  

Pending Asset Acquisition     On December 31, 2009, we entered into a definitive agreement to acquire substantially 
all of the US Rocky Mountain assets of Petro-Canada Resources (USA) Inc. and Suncor Energy (Natural Gas) 
America Inc. for $494 million. The acquisition is expected to close late in the first quarter 2010 and is subject to 
customary closing conditions. Funding is expected to be provided through our existing credit facility.  

Note 5.  Fair Value Measurements and Disclosures 

Assets and Liabilities Measured at Fair Value on a Recurring Basis   Certain assets and liabilities are measured 
at fair value on a recurring basis in our consolidated balance sheets.  The following methods and assumptions were 
used to estimate the fair values:  

Cash, Cash Equivalents, Accounts Receivable and Accounts Payable   The carrying amounts approximate fair value 
due to the short-term nature or maturity of the instruments.  

Mutual Fund Investments   Our mutual fund investments, which primarily include assets held in a rabbi trust, consist 
of various publicly-traded mutual funds that include investments ranging from equities to money market instruments. 
The fair values are based on quoted market prices for identical assets. 

Commodity Derivative Instruments   Our commodity derivative instruments consist of variable to fixed price 
commodity swaps, collars and basis swaps. We estimate the fair values of these instruments based on published 
forward commodity price curves as of the date of the estimate. The discount rate used in the discounted cash flow 
projections is based on published LIBOR rates, Eurodollar futures rates and interest swap rates. The fair values of 
commodity derivative instruments in an asset position include a measure of counterparty nonperformance risk, and 
the fair values of commodity derivative instruments in a liability position include a measure of our own 
nonperformance risk, each based on the current published credit default swap rates. In addition, for collars, we 
estimate the option value of the contract floors and ceilings using an option pricing model which takes into account 
market volatility, market prices and contract terms. See Note 6. Derivative Instruments and Hedging Activities. 

Patina Deferred Compensation Liability   The value is dependant upon the fair values of mutual fund investments and 
shares of our common stock held in a rabbi trust. See Mutual Fund Investments above.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis   Certain assets and liabilities are 
measured at fair value on a nonrecurring basis in our consolidated balance sheets. As of January 1, 2009, we 
adopted US GAAP fair value measurement standards as they related to our nonfinancial assets and liabilities.  

The following methods and assumptions were used to estimate the fair values for nonrecurring measurements made 
in 2009:  

Proved Property Impairments   In accordance with US GAAP for the impairment or disposal of long-lived assets, we 
review a proved oil and gas property for impairment when events and circumstances indicate a possible decline in the 
recoverability of the carrying value of such property. We estimate the future cash flows expected in connection with 
the property and compare such future cash flows to the carrying amount of the property to determine if the carrying 
amount is recoverable. If the carrying amount of the property exceeds its estimated undiscounted future cash flows, 
the carrying amount of the property is reduced to its estimated fair value. Fair value may be estimated using 
comparable market data, a discounted cash flow method, or a combination of the two. In the discounted cash flow 
method, estimated future cash flows are based on management’s expectations for the future and include estimates of 
future oil and gas production, commodity prices based on published forward commodity price curves as of the date of 
the estimate, operating and development costs, and a risk-adjusted discount rate.

Additional Fair Value Disclosures  

Debt   The fair value of fixed-rate debt is estimated based on the published market prices for the same or similar 
issues.  The fair value of floating-rate debt is estimated using the carrying amounts because the interest rates paid on 
such debt are set for periods of three months or less. See Note 8. Debt.

Note 6.  Derivative Instruments and Hedging Activities 

Objective and Strategies for Using Derivative Instruments   In order to reduce commodity price uncertainty and 
enhance the predictability of cash flows relating to the marketing of our crude oil and natural gas, we enter into crude 
oil and natural gas price hedging arrangements with respect to a portion of our expected production. The derivative 
instruments we use include variable to fixed price commodity swaps, collars and basis swaps. While these 
instruments mitigate the cash flow risk of future reductions in commodity prices they may also curtail benefits from 
future increases in commodity prices. We account for derivative instruments and hedging activities in accordance with 
US GAAP for derivative instruments and hedging activities, and all derivative instruments are reflected at fair value in 
our consolidated balance sheets. We elected to designate the majority of our commodity derivative instruments as 
cash flow hedges through December 31, 2007. As discussed in Note 2. Summary of Significant Accounting Policies – 
Derivative Instruments and Hedging Activities, we voluntarily discontinued cash flow hedge accounting for our 
commodity derivative instruments effective January 1, 2008. See Note 5. Fair Value Measurements and Disclosures 
for a discussion of methods and assumptions used to estimate the fair values of our commodity derivative 
instruments. See Note 2. Summary of Significant Accounting Policies – Concentration of Credit Risk for a discussion 
of counterparty credit risk. 

Accounting for Commodity Derivative Instruments   During 2009 and 2008, we accounted for our commodity 
derivative instruments using mark-to-market accounting, and we recognized all gains and losses on such instruments 
in earnings during the period in which they occur.  Prior to January 1, 2008, we elected to designate certain of our 
commodity derivative instruments as cash flow hedges. Net derivative gains and losses that were deferred in AOCL 
as of January 1, 2008, as a result of previous cash flow hedge accounting, are reclassified to earnings in future 
periods as the original hedged transactions occur.  See Derivative Instruments in Previously Designated Cash Flow 
Hedging Relationships table below.

the counterparty if the settlement price for the scheduled trading days applicable for each calculation period is more 
than the fixed price or ceiling price. The amount payable by us, if the floating price is above the fixed or ceiling price, 
is the product of the notional quantity per calculation period and the excess, if any, of the floating price over the fixed 
or ceiling price in respect of each calculation period. The amount payable by the counterparty, if the floating price is 
below the fixed or floor price, is the product of the notional quantity per calculation period and the excess, if any, of

(1) 

Includes effect of commodity derivative instruments previously accounted for as cash flow hedges. Net derivative 
gains and losses that were deferred in AOCL as of January 1, 2008, as a result of previous cash flow hedge 
accounting, are reclassified to earnings in future periods as the original hedged transactions occur. 

(2)  The amount of (gain) loss on derivative instruments reclassified from AOCL is recognized in oil, gas and NGL 

sales within our consolidated statements of operations. 

AOCL   As of December 31, 2009 and 2008, the balance in AOCL included net deferred losses of $12 million and $48 
million, respectively, related to the fair value of crude oil and natural gas derivative instruments accounted for as cash 
flow hedges. The net deferred losses are net of deferred income tax benefits of $7 million and $29 million, 
respectively. The net deferred losses (net of tax) related to the fair values of the commodity derivative instruments 
previously designated as cash flow hedges and remaining in AOCL at December 31, 2009 will be reclassified to 
earnings during the next 12 months as the forecasted transactions occur, and will be recorded as a reduction in oil 
and gas sales of approximately $20 million before tax. All forecasted commodity transactions currently being hedged 
are expected to occur by December 2010. 

Interest Rate Hedges   We occasionally enter into forward contracts or swap agreements to hedge exposure to 
interest rate risk. Changes in fair value of interest rate swaps or interest rate “locks” used as cash flow hedges are 
reported in AOCL, to the extent the hedge is effective, until the forecasted transaction occurs, at which time they are 
recorded as adjustments to interest expense over the term of the related notes. At December 31, 2009 and 2008, 
AOCL included deferred losses, net of tax, of $2 million and $3 million, respectively, related to interest rate swaps. 
This amount is being reclassified into earnings, at the rate of $0.8 million per year, as an adjustment to interest 
expense over the term of our 5¼% senior notes due 2014.  

In 2007, we entered into two additional interest rate locks, each in the notional amount of $500 million. The locks 
were based on five and ten year US Treasury rates of 3.55% and 4.15%, respectively, and were scheduled to expire 
in September 2008. We settled the locks in July 2008 at a total cost of $0.2 million.  

In January 2010, in anticipation of a long-term debt issuance, we entered into an interest rate forward starting swap to 
effectively fix the cash flows related to interest payments on the anticipated debt issuance. We are accounting for the 
instrument as a cash flow hedge against the variability of interest payments attributable to changes in interest rates 
on the forecasted issuance of fixed-rate debt. The swap is in the notional amount of $500 million and is based on a 
30-year LIBOR swap rate.

Blocks O and I (West Africa)   The West Africa project includes Blocks O and I offshore Equatorial Guinea and the 
YoYo mining concession and Tilapia production sharing contract offshore Cameroon. Since drilling the initial well for 
this project, additional seismic work has been completed and exploration and appraisal wells have been drilled to 
further evaluate our discoveries. The West Africa development team is proceeding with a program to further define 
the resources in this area such that an optimal development program may be designed.  

On July 22, 2009, we announced that the Plan of Development for the Aseng field (formerly Benita) on Block I has 
been sanctioned by us, our partners, and the Ministry of Mines, Industry, and Energy of the Republic of Equatorial 
Guinea.  As a result, we reclassified $76 million of capitalized costs relating to the Aseng field out of capitalized 
exploratory well costs and into proved oil and gas properties.  

We have evaluated the potential for additional liquids and gas projects, and expect that the next development will be 
at the Belinda field.  Belinda project sanction is currently scheduled to occur in 2010 with production beginning in 
2013. We are also evaluating future oil projects at Diega and Carmen and are currently scheduling first production for 
2014, subject to sanctioning. In Cameroon, we will acquire a 3-D seismic survey over YoYo and portions of Tilapia 
during 2010, and exploration drilling is currently planned in Tilapia for 2011.

Notes to Consolidated Financial Statements 

In addition to the remaining exploratory well costs that have been capitalized for a period greater than one year for 
the West Africa project, we have incurred $27 million in suspended costs related to additional drilling activity in West 
Africa through December 31, 2009. 

Gunflint (Deepwater Gulf of Mexico)   Gunflint (Mississippi Canyon Block 948) was a 2008 crude oil discovery and is 
our largest deepwater Gulf of Mexico discovery to date. We have acquired additional seismic information and are 
preparing to drill one or two appraisal wells in 2010. 

Redrock (Deepwater Gulf of Mexico)   Redrock (Mississippi Canyon Block 204) was a 2006 natural gas/condensate 
discovery and is currently considered a co-development candidate with South Raton (Mississippi Canyon Block 292). 
The anticipated development plan consists of tying South Raton back through the Gemini system to a host platform at 
Viosca Knoll Block 900 for processing and then connecting Redrock into this gathering system. Tie-back of Redrock 
is anticipated to occur following the development of South Raton. 

Flyndre (North Sea)   The Flyndre project is located in the UK sector of the North Sea and we successfully completed 
an exploratory appraisal well in 2007.  We are currently working with the project operator and other partners to 
finalize the field development plan and relevant operating agreements. 

Selkirk (North Sea)   The Selkirk project is also located in the UK sector of the North Sea. Capitalized costs to date 
primarily consist of the cost of drilling an appraisal well which was then sidetracked to the original discovery well 
location, to ensure presence of effective reservoir, and suspended as a future producer. We are currently working 
with our partners on an alternative host and to reduce costs.

(1)   We expect to use the credit facility to fund our planned $494 million acquisition of US Rocky Mountain assets in 

the first quarter 2010. See Note 4. Acquisitions and Divestitures – Pending Asset Acquisition. 

(2)  Amount reported is based on percentage of FPSO construction activities completed as of December 31, 2009 
and therefore does not reflect future minimum lease obligations. See Obligation Under FPSO Lease below. 

All of our long-term debt is senior unsecured debt and is, therefore, pari passu with respect to the payment of both 
principal and interest. The indenture documents of each of our notes provide that we may prepay the instruments by 
creating a defeasance trust. The defeasance provisions require that the trust be funded with securities sufficient, in 
the opinion of a nationally recognized accounting firm, to pay all scheduled principal and interest due under the 
respective agreements. Interest on each of these issues is payable semi-annually. Debt issuance costs of 
approximately $13 million remain and are being amortized to expense over the life of the related debt issues. 

Credit Facility   Our bank revolving credit facility (the credit facility) is committed in the amount of $2.1 billion until 
December 9, 2011 at which time the commitment reduces to $1.8 billion. The credit facility (i) provides for credit 
facility fee rates that range from 5 basis points to 15 basis points per year depending upon our credit rating, 
(ii) makes available short-term loans up to an aggregate amount of $300 million and (iii) provides for interest rates 
that are based upon the Eurodollar rate plus a margin that ranges from 20 basis points to 70 basis points depending 
upon our credit rating and utilization of the credit facility. The credit facility requires that our total debt to capitalization 
ratio (as defined in the credit agreement), expressed as a percentage, not exceed 60% at any time. A violation of this 
covenant could result in a default under the credit facility, which would permit the participating banks to restrict our 
ability to access the credit facility and require the immediate repayment of any outstanding advances under the credit

facility. As of December 31, 2009, we were in compliance with our debt covenants. The credit facility is with certain 
commercial lending institutions and is available for general corporate purposes. 

Certain lenders that are a party to the credit facility have in the past performed investment banking, financial advisory, 
lending or commercial banking services for us, for which they have received customary compensation and 
reimbursement of expenses.  

The credit facility does not restrict the payment of dividends on our common stock, except, if after giving effect 
thereto, an Event of Default shall have occurred and be continuing or been caused thereby. 

Debt Offering   On February 27, 2009, we closed an offering of $1 billion senior unsecured notes receiving net 
proceeds of $989 million, after deducting the discount and underwriting fees. The notes are due March 1, 2019, and 
pay interest semi-annually at 8¼%. Debt issuance costs of approximately $2 million were incurred and are being 
amortized to expense over the life of the debt issue. Substantially all of the net proceeds from the offering were used 
to repay outstanding indebtedness under our revolving credit facility maturing 2012. The notes are senior unsecured 
debt and rank pari passu with any of our other senior unsecured indebtedness with respect to the payment of both 
principal and interest.  

Obligation Under FPSO Lease   On October 6, 2009, we entered into an agreement with an unrelated offshore 
technology provider for the construction and lease of a floating production, storage and offloading vessel (FPSO) to 
be used for the development of the Aseng field, offshore Equatorial Guinea. We serve as technical operator of the 
development project with a 40% working interest. 

Construction of the FPSO is scheduled to be completed in 2012, at which time the FPSO will be delivered to Block I, 
offshore Equatorial Guinea, for the start-up of the Aseng field. The initial term of the lease is for a period of 15 years. 
We expect to account for the lease agreement as a capital lease. As a result, the FPSO will be included in oil and gas 
properties and the associated long-term obligation will be included in our balance sheet.  We expect that the lease 
obligation will total approximately $340 million, net to our 40% interest.  This amount represents our share of the 
expected present value of the future minimum lease payments, excluding executory costs, and is subject to change 
based on change orders implemented during the construction period, final accounting treatment and other factors. 

Throughout the construction phase, we will include both the FPSO asset and associated long-term obligation in our 
balance sheet, based upon the percentage of construction completed at the end of each reporting period. 

Monthly lease payments will exclude regular maintenance and operational costs, and will begin when the FPSO 
initiates producing operations.  Annual lease payments, net to our 40% interest, are expected to total approximately 
$69 million per year for years 1-4 of the lease agreement, $43 million per year for years 5-7; and $8 million per year 
for the remaining years of the initial 15-year lease term.  These payments are also subject to change based on 
change orders implemented during the construction period and other factors. 

Installment Payment Due 2009   On May 11, 2009, we made the final $25 million installment payment to the seller of 
properties we purchased in 2007. Interest on the unpaid amount was due quarterly and accrued at a LIBOR rate plus 
.30%. The interest rate was 1.51% at the date of payment. 

Debt Repurchases   In 2009, we repurchased $5 million of our 7¼% Senior Debentures due August 1, 2097, 
recognizing a debt extinguishment gain of $1 million. In 2008, we repurchased $11 million of the same notes, 
recognizing a debt extinguishment gain of $4 million. 

Annual Maturities   Annual maturities of outstanding debt, excluding FPSO lease payments, are as follows:

Short-Term Borrowings   Our credit agreement is supplemented by short-term borrowings under various uncommitted 
credit lines used for working capital purposes. Uncommitted credit lines may be offered by certain banks from time to 
time at rates negotiated at the time of borrowing. Other than the installment payments discussed above, no short-
term borrowings were outstanding at December 31, 2009 or 2008.

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or 
all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon 
the generation of future taxable income in the appropriate tax jurisdictions during the periods in which those 
temporary differences become deductible. We consider the scheduled reversal of deferred tax liabilities, projected 
future taxable income and tax planning strategies in making this assessment. Based upon the level of historical 
taxable income and projections for future taxable income over the periods in which the deferred tax assets are 
deductible, we believe it is more likely than not that we will realize the benefits of these deductible differences at 
December 31, 2009. The amount of the deferred tax assets considered realizable could be reduced in the future if 
estimates of future taxable income during the carryforward period are reduced. 

We have recognized deferred tax assets associated with foreign loss carryforwards. The tax effects of these 
carryforwards totaled $18 million in 2007, increased to $35 million in 2008, and increased to $47 million in 2009. 
Losses continue to be incurred on our projects in Equatorial Guinea and other new venture activities which are not 
yet commercial, and we also incurred a small loss in the UK. Therefore, a valuation allowance was provided 
against $45 million of the deferred tax assets, excluding the UK loss which we expect to utilize in 2010. In 2007, 
we fully utilized a loss carryforward that arose in the UK in 2006 from accelerated write-offs allowed on our 
Dumbarton field development. No valuation allowance had been provided against this loss carryforward.   

We have recorded a deferred tax asset of $28 million for the future foreign tax credits associated with deferred tax 
liabilities recorded by foreign branch operations. A valuation allowance of $28 million has been provided against this 
deferred tax asset.

Noble Energy, Inc. 
Notes to Consolidated Financial Statements 

Our effective tax rate increased to 50% in 2009 as compared with 35% in 2008 and is the result of a tax benefit 
divided by a pre-tax loss.  In the case of a loss, our favorable permanent differences, such as income from equity 
method investees, have the effect of increasing the tax benefit which, in turn, increases the effective rate.  

Our effective tax rate increased to 35% in 2008 as compared with 31% in 2007 primarily due to the fact that pre-tax 
earnings increased by a proportionately greater amount than our excludible permanent differences. In addition, there 
was a rate increase due to (1) a partial shift of taxable income from lower rate jurisdictions such as Equatorial Guinea 
and Israel to higher rate jurisdictions, (2) the recording of US deferred taxes on the anticipated repatriation of foreign 
earnings as described below, and (3) the recording of an impairment of a foreign asset on which the tax benefit was 
offset by a valuation allowance. 

During first quarter 2009, we repatriated $180 million of accumulated earnings of foreign subsidiaries and used the 
proceeds for debt repayment and general corporate purposes. The repatriation increased US tax expense by $13 
million, of which $9 million was recorded in 2008. Repatriation of additional earnings in the future could result in a 
decrease in our net income and cash flows. As of December 31, 2009, the accumulated undistributed earnings of the 
foreign subsidiaries on which no US taxes have been recorded were approximately $1.2 billion. Upon distribution of 
additional earnings in the form of dividends or otherwise, we would likely be subject to US income taxes and foreign 
withholding taxes. It is not practicable, however, to determine precisely the amount of taxes that may be payable on 
the eventual remittance of these earnings because of the possible application of US foreign tax credits. Although we 
are currently claiming foreign tax credits, we may not be in a credit position when any future remittance of foreign 
earnings takes place, or the limitations imposed by the Internal Revenue Code and IRS Regulations may not allow 
the credits to be utilized during the applicable carryback and carryforward periods. However, if full use of tax credits is 
assumed, we estimate that the future US taxes on eventual remittance would be approximately $230 million. 

In 2007, China’s legislature, the National People’s Congress, enacted the China Corporate Income Tax Law.  This 
new legislation decreased our tax rate in China from 33% to 25% starting in 2008, resulting in a $2 million reduction 
in deferred tax expense. 

Adoption of US GAAP for Accounting for Uncertainty in Income Taxes   As discussed in Note 2—Significant 
Accounting Policies, we adopted US GAAP for accounting for uncertainty in income taxes, including unrecognized tax 
benefits as of January 1, 2007. The adoption had no effect on our financial position or results of operations. We did 
not have significant unrecognized tax benefits resulting from differences between positions taken in tax returns and 
amounts recognized in the financial statements as of December 31, 2008 or 2009. Our policy is to recognize any 
interest and penalties related to unrecognized tax benefits in income tax expense. However, we did not accrue 
interest or penalties at December 31, 2008 or 2009, because the jurisdiction in which we have unrecognized tax 
benefits does not currently impose interest on underpayments of tax and we believe that we are below the minimum 
statutory threshold for imposition of penalties. We do not expect that the total amount of unrecognized tax benefits 
will significantly increase or decrease during the next 12 months.  

In our major tax jurisdictions, the earliest years remaining open to examination are as follows: US – 2006, Equatorial 
Guinea – 2007, China – 2006, Israel – 2000, UK – 2007 and the Netherlands – 2005. 

Note 10.  Asset Retirement Obligations 

Asset retirement obligations consist of estimated costs of dismantlement, removal, site reclamation and similar 
activities associated with our oil and gas properties. An asset retirement obligation and the related asset 
retirement cost are recorded when an asset is first constructed or purchased. The asset retirement cost is 
determined and discounted to present value using a credit-adjusted risk-free rate. After initial recording the liability 
is increased for the passage of time, with the increase being reflected as accretion expense in the statement of 
operations. Subsequent adjustments in the cost estimate are reflected in the liability and the amounts continue to be 
amortized over the useful life of the related long-lived asset. 

Changes in asset retirement obligations are as follows:

in the Main Pass and Viosca Knoll areas of the Gulf of Mexico.  Revisions relate to the Main Pass asset and a 
deepwater Gulf of Mexico property. 

For the year ended December 31, 2008, liabilities settled related primarily to onshore US and Gulf of Mexico assets. 
Revisions include $15 million related to our Main Pass asset held for sale at December 31, 2008. The remaining 
revisions resulted from changes in estimated timing of actual abandonment and overall cost increases for the North 
Sea assets ($18 million), onshore US and Gulf of Mexico assets ($38 million) and Israel and other locations ($4 
million).  

Accretion expense is included in depreciation, depletion and amortization expense in the consolidated statements 
of operations. 

Note 11.  Equity Method Investments 

Investments accounted for under the equity method consist primarily of the following: 

•  45% interest in Atlantic Methanol Production Company, LLC (AMPCO), which owns and operates a methanol 

plant and related facilities in Equatorial Guinea; and 

•  28% interest in Alba Plant LLC (Alba Plant), which owns and operates a liquefied petroleum gas processing 

plant in Equatorial Guinea. 

Equity method investments are included in other noncurrent assets in the consolidated balance sheets, and our share 
of earnings is reported as income from equity method investees in the consolidated statements of operations. Our 
share of income taxes incurred directly by the equity method investees is reported in income from equity method 
investments and is not included in our income tax provision in our consolidated statements of operations. At 
December 31, 2009, our retained earnings included $123 million related to the undistributed earnings of equity 
method investees. 

The carrying value of our AMPCO investment is $24 million higher than the underlying net assets of the investee.  
$12 million of the difference relates to capitalized interest which is being amortized into earnings over the remaining 
useful life of the plant.  The remaining $12 million relates to a note receivable from our funding a portion of the local 
government’s share of the plant’s development.  The note receivable is being recovered through distributions from 
AMPCO.

Note 12.  Benefit Plans 

Pension Plan and Other Postretirement Benefit Plans   We have a noncontributory, tax-qualified defined benefit 
pension plan covering employees who were hired prior to May 1, 2006.  The benefits are based on an employee’s 
years of service and average earnings for the 60 consecutive calendar months of highest compensation. Our funding 
policy has been to make annual contributions equal to at least the minimum required contribution, but no greater than 
the maximum deductible for federal income tax purposes. We also have an unfunded, nonqualified restoration plan 
that provides the pension plan formula benefits that cannot be provided by the qualified pension plan because of pay 
deferrals and the compensation and benefit limitations imposed on the pension plan by the Internal Revenue Code of 
1986, as amended. We sponsor other plans for the benefit of our employees and retirees, which include medical and 
life insurance benefits. We use a December 31 measurement date for the plans. 

We recognize the funded status (the difference between the fair value of plan assets and the benefit obligation) of our 
defined benefit pension, restoration and other postretirement benefit plans in the consolidated balance sheets, with a 
corresponding adjustment to AOCL, net of tax. The amount remaining in AOCL at December 31, 2009 represents 
unrecognized net actuarial loss, unrecognized prior service cost, and unrecognized net transition obligation remaining 
from the initial adoption of US GAAP for employers’ accounting for pensions and other postretirement benefits. These 
amounts are currently being recognized as net periodic benefit cost pursuant to our historical accounting policy for 
amortizing such amounts. Any actuarial gains and losses that arise during the plan year, but which are not required to 
be recognized as net periodic benefit cost in the same period, are recognized as a component of AOCL.

In selecting the assumption for expected long-term rate of return on assets, we consider the average rate of earnings 
expected on the funds to be invested to provide for plan benefits. This includes considering the plan’s asset 
allocation, historical returns on these types of assets, the current economic environment and the expected returns

likely to be earned over the life of the plan. We assume the long-term asset mix will be consistent with a target asset 
allocation of 70% equity and 30% fixed income, with a range of plus or minus 10% acceptable degree of variation in 
the plan’s asset allocation. Based on these factors we assumed an average of 8.00% per annum over the life of the 
plan for the calculation of 2009 net periodic benefit cost. The assumption will be reduced to 7.50% for the calculation 
of 2010 net periodic benefit cost. No plan assets are expected to be returned to us in 2010. 

In order to determine an appropriate discount rate at December 31, 2009, we performed an analysis of the Citigroup 
Pension Discount Curve (the CPDC) as of that date for each of our plans. The CPDC uses spot rates that represent 
the equivalent yield on high quality, zero coupon bonds for specific maturities. We used these rates to develop an 
equivalent single discount rate based on our plans’ expected future benefit payment streams and duration of plan 
liabilities. A 1% increase in the discount rate would have resulted in a decrease in net periodic benefit cost of 
approximately $2 million in 2009. A 1% decrease in the discount rate would have resulted in an increase in net 
periodic benefit cost of approximately $2 million in 2009.

The investment policy for the tax-qualified defined benefit pension plan is determined by an employee benefits 
committee (the committee) with input from a third-party investment consultant. Based on a review of historical rates of 
return achieved by equity and fixed income investments in various combinations over multi-year holding periods and 
an evaluation of the probabilities of achieving acceptable real rates of return, the committee has determined the 
target asset allocation deemed most appropriate to meet the immediate and future benefit payment requirements for 
the plan and to provide a diversification strategy which reduces market and interest rate risk. The fixed income 
allocation is expected to directionally track a portion of the plan’s liabilities, thus reducing overall plan interest rate 
risk.  A 1% increase (decrease) in the expected return on plan assets would have resulted in a (decrease) increase, 
respectively, in net periodic benefit cost of approximately $2 million in 2009. 

We base our determination of the asset return component of pension expense on a market-related valuation of 
assets, which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses 
over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the 
difference between the expected return calculated using the market-related value of assets and the actual return 
based on the fair value of assets. Since the market-related value of assets recognizes gains or losses over a five-
year period, the future value of assets will be impacted as previously deferred gains or losses are recorded. As of 
January 1, 2010, we had cumulative asset gains (losses) of approximately $(16) million, which remain to be 
recognized in the calculation of the market-related value of assets.

Additional information about plan assets, including methods and assumptions used to estimate the fair values of plan 
assets, is as follows:  

Federal Money Market Funds    Investments in federal money market funds consist of portfolios of high quality fixed 
income securities (such as US Treasury securities) which, generally, have maturities less than one year.  The fair 
value of these investments is based on quoted market prices for identical assets as of the measurement date.     

Mutual Funds   Investments in mutual funds consist of diversified portfolios of common stocks and fixed income 
instruments.  The common stock mutual funds are diversified by market capitalization and investment style as well as 
economic sector and industry.  The fixed income mutual funds are diversified primarily in government bonds, 
mortgage backed securities, and corporate bonds, most of which are rated investment grade.  The fair values of 
these investments are based on quoted market prices for identical assets as of the measurement date.   

Common Collective Trust Funds    Investments in common collective trust funds consist of common stock 
investments in both US and non-US equity markets.  Portfolios are diversified by market capitalization and investment 
style as well as economic sector and industry. The investments in the non-US equity markets are used to further 
enhance the plan’s overall equity diversification which is expected to moderate the plan’s overall risk volatility.  In 
addition to the normal risk associated with stock market investing, investments in foreign equity markets may carry 
additional political, regulatory, and currency risk which is taken into account by the committee in its deliberations. The 
fair value of these investments is based on quoted prices for similar assets in active markets. All of the investments in 
Common Collective Trust Funds represent exchange-traded securities with readily observable prices.   

Contributions   As a result of previous contributions made to the pension plan, there are no required contributions 
expected in 2010. In January 2010, we made a voluntary contribution of $2 million to the pension plan. We may make 
additional contributions to our pension plan during the year. We expect to make cash contributions of approximately 
$2 million to the unfunded restoration plan and $1 million to the medical and life plans in 2010. The amounts 
expected to be contributed to the unfunded restoration and medical and life plans equal expected benefit payments 
from those plans. (unaudited). 

Estimated Future Benefit Payments   As of December 31, 2009, the following future benefit payments are expected to 
be paid:

The  estimate of expected future benefit payments is based on the same assumptions used to measure the benefit 
obligation at December 31, 2009 and includes estimated future employee service. 

401(k) Plan      We  sponsor  a  401(k) savings  plan.  All  regular  employees  are  eligible  to  participate.  We  make 
contributions to match employee contributions up to the first 6% of compensation deferred into the plan, and certain 
profit  sharing  contributions  for  employees  hired  on  or  after  May  1,  2006,  based  upon  their  ages  and  salaries. We 
made cash contributions of $9 million in 2009, $7 million in 2008, and $6 million in 2007.

Deferred Compensation Plans   In connection with the Patina Merger, we acquired the assets and assumed the 
liabilities related to a Patina shareholder-approved non-qualified deferred compensation plan. This plan was available 
to officers and certain managers of Patina and allowed participants to defer all or a portion of their salary and annual 
bonuses (either in cash or common stock). Participant-directed investments are held in a rabbi trust and are available 
to satisfy the claims of our creditors in the event of bankruptcy or insolvency. Participants may elect to receive 
distributions in either cash or shares of our common stock. Components of the rabbi trust are as follows:

balance sheets. 

Assets of the rabbi trust, other than our common stock, are invested in certain mutual funds that cover an investment 
spectrum ranging from equities to money market instruments. These mutual funds have published market prices and 
are reported at fair value. See Note 5. Fair Value Measurements and Disclosures. The mutual funds are included in 
the mutual fund investments account in other noncurrent assets in the consolidated balance sheets.  

Shares of our common stock held by the rabbi trust are accounted for as treasury stock (recorded at cost) in the 
shareholders’ equity section of the consolidated balance sheets. The amounts payable to the plan participants are 
included in other noncurrent liabilities in the consolidated balance sheets and include the market value of the shares 
of our common stock. Approximately one million shares, or 95%, of our common stock held in the plan at 
December 31, 2009 were attributable to a member of our Board of Directors. Plan participants sold 1,892 shares of  
our common stock in 2009, 50,000 shares in 2008, and no shares in 2007. Proceeds were invested in mutual funds. 
Distributions to plan participants totaled $1 million in 2008 and $2 million in 2007. Distributions to plan participants 
were de minimis in 2009. 

All fluctuations in market value of the deferred compensation liability have been reflected in other non-operating 
(income) expense, net in the consolidated statements of operations. We recognized deferred compensation expense 
of $23 million in 2009, deferred compensation income of $32 million in 2008, and deferred compensation expense of 
$33 million in 2007. 

We also maintain an unfunded deferred compensation plan for the benefit of certain of our employees. Deferred 
compensation liabilities of $45 million and $36 million were outstanding at December 31, 2009 and 2008, 
respectively, under the unfunded plan.

Stock Option and Restricted Stock Plans and Incentive Plan   Our stock option and restricted stock plans and 
incentive plan are described below. 

1992 Stock Option and Restricted Stock Plan      Under the Noble Energy, Inc. 1992 Stock Option and Restricted 
Stock Plan, as amended (the 1992 Plan), the Compensation, Benefits and Stock Option Committee of the Board of 
Directors (the Committee) may grant stock options and award restricted stock to our officers or other employees and 
those of our subsidiaries. In 2007, our stockholders approved an amendment to the 1992 Plan that increased the 
maximum number of shares of our common stock that may be issued from 18 million to 22 million shares. In 2009, 
our stockholders approved an amendment to the 1992 Plan that increased the maximum number of shares of our 
common stock that may be issued from 22 million to 24 million shares. At December 31, 2009, 12,263,457 shares of 
our common stock were reserved for issuance, including 4,706,057 shares available for future grants and awards, 
under the 1992 Plan. 

Stock options are issued with an exercise price equal to the market price of our common stock on the date of grant, 
and are subject to such other terms and conditions as may be determined by the Committee. Unless granted by the 
Committee for a shorter term, the options expire ten years from the grant date. Option grants generally vest ratably 
over a three-year period. 

Restricted stock awards made under the 1992 Plan are subject to such restrictions, terms and conditions, including 
forfeitures, if any, as may be determined by the Committee. Restricted stock awards generally vest over three years. 
In 2009, we began making grants of restricted stock under the 1992 Plan that time-vest 20% after year one, an 
additional 30% after year two and the remaining 50% after year three. 

2004 Long-Term Incentive Plan    Under the Noble Energy, Inc. 2004 Long-Term Incentive Plan (the 2004 LTIP), the 
Committee may make incentive awards to our key employees and those of our subsidiaries. Incentive compensation 
is based upon the attainment of specific market and performance goals established by the Committee. Awards may 
be in the form of stock options or restricted stock or in the form of performance units or other incentive measurements 
providing for the payment of bonuses in cash, or in any combination thereof, as determined by the Committee in its 
discretion. Stock options granted and restricted stock awarded under the 2004 LTIP are granted and awarded 
pursuant to the terms of the 1992 Plan. These awards are accounted for in accordance with US GAAP for stock-
based compensation, which provides for the grant-date fair value of the awards to be recognized in the statement of 
operations over the service period. Our cash based performance units, which were issued in 2006 and vested in 
2009, were accounted for in accordance with US GAAP for contingencies. 

2005 Stock Plan for Non-Employee Directors   The 2005 Stock Plan for Non-Employee Directors of Noble 
Energy, Inc. (the 2005 Plan) provides for grants of stock options and awards of restricted stock to our non-employee 
directors. The 2005 Plan superseded and replaced the 1988 Nonqualified Stock Option Plan for Non-Employee 
Directors. The total number of shares of our common stock that may be issued under the 2005 Plan is 800,000. At 
December 31, 2009, 730,349 shares of our common stock were reserved for issuance, including 568,841 shares 
available for future grants and awards under the 2005 Plan. 

The 2005 Plan provides for the granting to a non-employee director of up to a maximum of 11,200 stock options on 
the date of election to the Board of Directors, annual grants of 2,800 options per non-employee director on 
February 1 of each year, and discretionary grants by the Board of Directors (with the February 1 annual and the 
discretionary grants made to a non-employee director during any calendar year being limited to a combined 
maximum of 11,200 options). Options are issued with an exercise price equal to the market price of our common 
stock on the date of grant and may be exercised one year after the date of grant. The options expire ten years from 
the date of grant. 

The 2005 Plan also provides for the awarding to a non-employee director of up to a maximum of 4,800 shares of 
restricted stock on the date of election to the Board of Directors, annual awards of 1,200 shares of restricted stock 
per non-employee director on February 1 of each year, and discretionary awards by the Board of Directors (with the 
February 1 annual and the discretionary awards made to a non-employee director during any calendar year being 
limited to a combined maximum of 4,800 shares of restricted stock). Restricted stock is restricted for a period of at 
least one year from the date of award.

Non-Employee Directors of Noble Energy, Inc., as amended, (the 1988 Plan) provided for the issuance of stock 
options to our non-employee directors. Options issued under the 1988 Plan may be exercised one year after grant 
and expire ten years from the grant date. The 1988 Plan provided for the granting of a fixed number of stock options 
to each non-employee director annually (10,000 stock options for the first calendar year of service and 5,000 stock 
options for each year thereafter) on February 1 of each year. The 1988 Plan was terminated in 2005, and no 
additional options can be granted thereunder. 

Patina Stock Option Plans   Patina maintained a shareholder approved stock option plan for employees (the Patina 
Employee Plan) that provided for the issuance of options at prices not less than fair value at the date of grant. Patina 
also maintained a shareholder approved stock grant and option plan for non-employee directors (the Patina Directors’ 
Plan). The Patina Directors’ Plan provided for stock options to be granted to each non-employee director upon 
appointment and upon annual re-election thereafter. Upon completion of the Patina Merger, all unvested stock 
options outstanding under the Patina Employee Plan and the Patina Directors’ Plan became fully vested, and all 
outstanding options were converted into options to purchase our common stock. The remaining Patina options expire 
in 2010. 

Stock Option Grants   The fair value of each stock option granted was estimated on the date of grant using a Black-
Scholes-Merton option valuation model that used the assumptions described below: 

•  Expected term   The expected term represents the period of time that options granted are expected to be 
outstanding, which is the grant date to the date of expected exercise or other expected settlement for 
options granted. The hypothetical midpoint scenario we use considers our actual exercise and post-vesting 
cancellation history and expectations for future periods, which assumes that all vested, outstanding options 
are settled halfway between their vesting date and their expiration date.  

•  Expected volatility   The expected volatility represents the extent to which our stock price is expected to 

fluctuate between the grant date and the expected term of the award. We use the historical volatility of our 
common stock for a period equal to the expected term of the option prior to the date of grant. We believe 
that historical volatility produces an estimate that is representative of our expectations about the future 
volatility of our common stock over the expected term. 

•  Risk-free rate   The risk-free rate is the implied yield available on US Treasury securities with a remaining 
term equal to the expected term of the option. We base our risk-free rate on a weighting of five and seven 
year US Treasury securities as of the date of grant to arrive at an approximated 5.5-year risk free rate of 
return.  

•  Dividend yield   The dividend yield represents the value of our stock’s annualized dividend as compared to 
our stock’s average price for the three-year period ended prior to the date of grant. It is calculated by 
dividing one full year of our expected dividends by our average stock price over the three-year period ended 
prior to the date of grant.

The  weighted-average  grant-date  fair value  of options  granted  was  $19.14 in  2009, $20.40 in  2008,  and  $18.77 in 
2007. The total intrinsic value of options exercised was $19 million in 2009, $67 million in 2008, and $68 million in 
2007. 

As  of  December 31,  2009,  $29 million  of  compensation  cost  related  to  unvested  stock  options  granted  under  the 
Plans  remained  to  be  recognized.  The  cost  is  expected  to  be  recognized  over  a  weighted-average  period  of  1.4 
years. We issue new shares of our common stock to settle option exercises. Dividends are not paid on unexercised 
options.

The total fair value of restricted stock that vested was $4 million in 2009, $10 million in 2008, and $6 million in 2007.  

Awards of time-vested restricted stock (shares subject to service conditions) were valued at the price of our common 
stock at the date of award. 

In 2006, we awarded restricted stock with market-based vesting criteria. The fair value of the market-based restricted 
stock awards was estimated on the date of award using a Monte Carlo valuation model that used an expected 
volatility assumption of 28.4% and a risk free rate assumption of 4.4%. The Monte Carlo model is based on random 
projections of stock price paths and must be repeated numerous times to achieve a probabilistic assessment. The 
number of simulations used was 100,000. Expected volatility represents the extent to which our stock price is 
expected to fluctuate between the award date and the award’s anticipated term. We used the historical volatility of our 
common stock for the three-year period ended prior to the date of award. The risk-free rate was based on a three-
year period from US Treasury securities as of the year ended prior to the date of award.  These awards vested in 
2009. 

As of December 31, 2009, $33 million of compensation cost related to all of our unvested restricted stock awarded 
under the Plans remained to be recognized. The cost is expected to be recognized over a weighted-average period of 
1.4 years. Common stock dividends accrue on restricted stock grants and are paid upon vesting. We issue new 
shares of our common stock when awarding restricted stock. 

Note 14.  Earnings Per Share 

Basic earnings per share of our common stock is computed using the weighted average number of shares of 
common stock outstanding during each period. The diluted earnings per share of our common stock may include the 
effect of our shares held in a rabbi trust, outstanding stock options or shares of restricted stock, except in periods in 
which there is a net loss. The following table summarizes the calculation of basic and diluted earnings per share:

Notes to Consolidated Financial Statements 

(1)  The diluted earnings per share calculation for 2008 includes a decrease to net income of $20 million (net of tax) 
related to a deferred compensation gain from shares of our common stock held in a rabbi trust. When dilutive, 
the deferred compensation gain or loss (net of tax) is excluded from net income while the shares of our common 
stock held in the rabbi trust are included in the outstanding diluted share count. 

The effect of stock options and unvested shares of restricted stock outstanding has not been included in the 
calculation of weighted average shares outstanding for diluted earnings per share for the year ended December 31, 
2009 as their effect would have been antidilutive. Had we recognized net income for this period, incremental shares 
attributable to the assumed exercise of outstanding options and shares of restricted stock would have increased 
diluted weighted average shares outstanding by 2 million shares for the year ended December 31, 2009. 

A total of 3.7 million, 1.2 million, and 2.1 million weighted average stock options, shares of restricted stock and shares 
of our common stock held in a rabbi trust were antidilutive for the years ended December 31, 2009, 2008 and 2007, 
respectively, and were excluded from the calculation of diluted earnings per share.  The weighted average exercise 
prices of the antidilutive stock options were $60.40 per share, $67.64 per share, and $52.41 per share for the years 
ended December 31, 2009, 2008 and 2007, respectively. 

Note 15.  Segment Information 

We have operations throughout the world and manage our operations by country. The following information is 
grouped into five components that are all primarily in the business of crude oil and natural gas exploration, 
development, and acquisition: the United States; West Africa (Equatorial Guinea and Cameroon); Eastern 
Mediterranean (Israel and Cyprus); the North Sea (UK and the Netherlands); and Other International, Corporate and 
Marketing. Other International includes China, Ecuador and Argentina (through February 2008) operations and the 
gain on sale of Argentina (in 2009). 

Accounting policies for geographical segments are the same as those described in the summary of significant 
accounting policies. Transfers between segments are accounted for at market value. We do not consider interest 
income and expense or income tax benefit or expense in our evaluation of the performance of geographical 
segments.

Note 17.  Commitments and Contingencies 

Purchaser Bankruptcy   We had an exposure from crude oil sales for the months of June and July 2008 to 
SemCrude, L.P. (SemCrude), a subsidiary of SemGroup, L.P. (SemGroup).  On July 22, 2008, SemGroup, including 
SemCrude, filed a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code under Case Number 
08-11525 (BLS) in the United States Bankruptcy Court for the District of Delaware. During 2008, we determined that 
the carrying value of our receivable of $71 million should be reduced by $38 million. Based upon the confirmation of 
SemCrude's plan for reorganization on October 26, 2009, and further based upon a settlement reached with 
SemCrude on October 27, 2009, we further reduced the carrying value of our receivable by $12 million. We have 
received distributions of approximately $12 million from SemCrude and believe the disposition of this matter to be 
finally determined. 

Legal Proceedings   We are involved in various other legal proceedings in the ordinary course of business.  These 
proceedings are subject to the uncertainties inherent in any litigation.  We are defending ourselves vigorously in all 
such matters and we believe that the ultimate disposition of such proceedings will not have a material adverse effect 
on our financial position, results of operations or cash flows. 

Non-Cancelable Leases and Other Commitments   We hold leases and other commitments for drilling rigs, buildings, 
equipment and other property. Rental expense for office buildings and oil and gas operations equipment was 
approximately $22 million in 2009, $20 million in 2008, and $13 million in 2007.

Noble Energy, Inc. 
Supplemental Oil and Gas Information 
(Unaudited) 

In accordance with US GAAP for disclosures about oil and gas producing activities, and SEC rules for oil and gas 
reporting disclosures, we are making the following disclosures about our crude oil and natural gas reserves and 
exploration and production activities. 

Reserves 

There are numerous uncertainties inherent in estimating quantities of proved crude oil and natural gas reserves. 
Crude oil and natural gas reserve engineering is a subjective process of estimating underground accumulations of 
crude oil and natural gas that cannot be precisely measured. The accuracy of any reserve estimate is a function of 
the quality of available data and of engineering and geological interpretation and judgment. Results of drilling, testing 
and production subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserves 
estimates are often different from the quantities of crude oil and natural gas that are ultimately recovered. 

Recent SEC and FASB Rule-Making Activity   In December 2008, the SEC announced that it had approved 
revisions designed to modernize the oil and gas company reserves reporting requirements. See Note 2. Summary of 
Significant Accounting Policies – Recently Adopted Standards. We adopted the rules effective December 31, 2009 
and the rule changes, including those related to pricing and technology, are included in our reserves estimates.  

In addition, in January 2010 the FASB issued Accounting Standards Update 2010-03, “Oil and Gas Reserve 
Estimation and Disclosures”, to provide consistency with the SEC rules. See Note 2. Summary of Significant 
Accounting Policies – Recently Adopted Standards.  

Application of the new rules resulted in the use of lower prices at December 31, 2009 for both oil and gas than would 
have resulted under the previous rules. Use of 12-month average pricing at December 31, 2009 as required by the 
new rules resulted in a decrease in proved reserves of approximately 27 MMBoe. Use of year-end prices as required 
by the old rules would have resulted in an increase in proved reserves of approximately 34 MMBoe at December 31, 
2009.  Therefore, the total impact of the new price methodology was negative reserves revisions of 61 MMBoe.  In 
addition, the new proved undeveloped reserves rules resulted in a reduction of proved reserves of approximately 18 
MMBoe due to limiting proved undeveloped reserves locations to those scheduled to be drilled within the next five 
years. The majority of the reserves reclassified out of proved reserves were associated with the Wattenberg field, 
where we maintain an extensive multi-year development program. 

Because we use quarter-end reserves and add back current period production to calculate quarterly DD&A, adoption 
of the new standards had an impact on fourth quarter 2009 DD&A expense. We estimate the impact of using 12-
month average commodity prices, as required by the new standards, instead of year-end commodity prices, to be an 
increase in fourth quarter 2009 DD&A expense of approximately $16 million (or $0.06 per share). 

Reserves Estimates    Qualified petroleum engineers in our Houston, Denver and London offices prepare all 
reserves estimates for our different geographical regions. These reserves estimates are reviewed and approved by 
regional management and senior engineering staff with final approval by the Vice President - Strategic Planning, 
Environmental Analysis & Reserves and certain members of senior management. For additional information 
regarding our reserves estimation process and internal controls see Items 1. and 2. Business and Properties – 
Proved Reserves Disclosures –  Internal Controls Over Reserves Estimates and Technologies Used in Reserves 
Estimation. 

Third-Party Reserves Audit   We retained Netherland, Sewell & Associates, Inc. (NSAI), independent, third-party 
reserves engineers, to perform a reserves audit of proved reserves as of December 31, 2009. The reserves audit 
included a detailed review of 20 of our major international, deepwater Gulf of Mexico and US onshore fields, which 
covered approximately 78% of US proved reserves and 96% of international proved reserves (86% of total proved 
reserves). For additional information regarding reserves audits for the years 2009, 2008, and 2007, see Items 1. and 
2. Business and Properties – Proved Reserves Disclosures. 

Geographic Areas   Our supplemental disclosures are grouped by geographic area and include the United States, 
Equatorial Guinea, Israel and Other International. Other International includes Ecuador, North Sea, China, and 
Argentina (through February 2008). Operations in Equatorial Guinea, Ecuador, China, Cyprus and Suriname are 
conducted in accordance with the terms of production sharing contracts. Operations in Cameroon are conducted in 
accordance with the terms of a production sharing contract and a mining concession. Operations in other foreign 
locations are conducted in accordance with concession agreements or licenses. 

Definitions   The following definitions apply to the terms used in the paragraphs above: 

Reserves Estimate   The determination of an estimate of a quantity of oil or gas reserves that are thought to exist at a 
certain date, considering existing prices and reservoir conditions. 

Reserves Audit   The process of reviewing certain of the pertinent facts interpreted and assumptions underlying a 
reserves estimate prepared by another party and the rendering of an opinion about the appropriateness of the 
methodologies employed, the adequacy and quality of the data relied upon, the depth and thoroughness of the 
reserves estimation process, the classification of reserves appropriate to the relevant definitions used, and the 
reasonableness of the estimated reserves quantities.

Noble Energy, Inc. 
Supplemental Oil and Gas Information 
(Unaudited) 

The following definitions apply to our categories of proved reserves: 

Proved Oil and Gas Reserves  Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of 
geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a 
given date forward, from known reservoirs, and under existing economic conditions, operating methods, and 
government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence 
indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for 
the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably 
certain that it will commence the project within a reasonable time. 

Developed Oil and Gas Reserves   Proved developed oil and gas reserves are reserves that can be expected to be 
recovered through existing wells with existing equipment and operating methods or in which the cost of the required 
equipment is relatively minor compared with the cost of a new well. 

Undeveloped Oil and Gas Reserves  Proved undeveloped oil and gas reserves are reserves that are expected to be 
recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required 
for recompletion. 

For complete definitions of proved natural gas, natural gas liquids and crude oil reserves, refer to SEC Regulation 
S-X, Rule 4-10(a)(6), (22) and (31).

(1)  Other International includes the North Sea, China and Argentina. We sold our Argentina assets in February 

2008.  

(2)  The 2007 positive revisions within the US are primarily due to 29 MMBbl of NGLs, previously recorded in proved 
natural gas reserves, being reflected in proved oil reserves, partially offset by negative revisions within the US 
Southern region related to less than expected well performance. The 2008 negative revisions within the US are 
primarily due to lower year-end prices (28 MMBbl), partially offset by the recording of NGLs which had 
previously been recorded in proved natural gas reserves. The 2009 negative revisions within the US are 
primarily due to performance revisions, the majority of which related to Main Pass (10 MMBbl) and 
reclassifications of proved undeveloped reserves to probable reserves as a result of the SEC’s new five year 
development rule (5 MMBbl), partially offset by higher year-end prices (10 MMBbl). 

(3)  The 2007 increase in proved reserves includes 17 MMBbl in the US Wattenberg field, primarily due to infill 
drilling activities, 8 MMBbl in the deepwater Gulf of Mexico and 10 MMBbl in the North Sea Dumbarton field 
area. The 2008 increase in proved reserves includes 13 MMBbl in the US Wattenberg field, primarily due to infill 
drilling activities, and 9 MMBbl in China. The 2009 increase in proved reserves includes 20 MMBbl related to the 
ongoing development of the US Wattenberg field, 11 MMBbl in the deepwater Gulf of Mexico for the Santa Cruz, 
Isabela and Swordfish fields, and 26 MMBbl in Equatorial Guinea for the Aseng field.         

(4)  Equatorial Guinea production includes sales from the Alba field to the Alba LPG plant of 3 MMBbl in 2009, 3 

MMBbl in 2008, and 3 MMBbl in 2007. 

 (5)  The decrease is due to sale of our Argentina assets. See Note 4. Acquisitions and Divestitures.

impairment charges related to our investment in Ecuador.  

(2)  The 2007 negative revisions within the US are primarily due to 103 Bcf of natural gas being reflected in the 

proved oil reserves table as NGLs, partially offset by positive revisions resulting from an increase in commodity 
price. The 2008 negative revisions in the US are primarily due to lower year-end prices (109 Bcf), as well as 
additional natural gas volumes being reflected in the proved oil reserves table as NGLs. The 2009 negative 
revisions in the US are primarily due to lower year-end prices (224 Bcf), reclassifications of proved undeveloped 
reserves to probable reserves as a result of the SEC’s new five year development rule (75 Bcf), and increased 
lease operating expense and various well performance issues (98 Bcf). Equatorial Guinea’s positive revisions in 
2007, 2008 and 2009 are primarily due to additional production allowances related to LNG sales. The 2007 
positive revisions in Ecuador are related to better than expected well performance. 

 (3)  The 2007 increase in US proved reserves includes 142 Bcf in the Wattenberg field, 83 Bcf in the Piceance basin 
and 19 Bcf in the Niobrara trend, primarily due to infill drilling activities. The 2008 increase in US proved reserves 
includes 106 Bcf in the Wattenberg field and 173 Bcf in the Rocky Mountain area, primarily in the Piceance basin 
and Niobrara trend, primarily due to infill drilling activities. The remaining increase is due to other development 
programs in the US Northern and Southern regions. The 2009 increase in US proved reserves is primarily due to 
ongoing low-risk development programs onshore in the Wattenberg field, the Rocky Mountain area, and East 
Texas. 

(4)  Purchase  of  minerals  in  place  is  primarily  due  to  the  Mid-continent  acquisition.  See  Note 4.  Acquisitions  and 

Divestitures.

Prices and Other Assumptions in Discounted Future Net Cash Flows (Unaudited)   Future cash inflows are 
computed by applying a 12-month average commodity price, adjusted for location and quality differentials on a field-
by-field basis, to year-end quantities of proved reserves, except in those instances where fixed and determinable 
price changes are provided by contractual arrangements at year-end. The discounted future cash flow estimates do 
not include the effects of derivative instruments. Average prices per region are as follows:

(1)  Other International includes the North Sea, Ecuador, and China at December 31, 2009, 2008 and 2007 and also 

(2) 

includes Argentina at December 31, 2007. 
  The new SEC and FASB reserves reporting rules require the use of 12-month average commodity prices instead 
of year-end commodity prices.  

We estimate that a $1.00 per Bbl change in the average price of crude oil or a $.10 per Mcf change in the average 
price of natural gas from the 12-month average prices for 2009 would change the discounted future net cash flows 
before income taxes by approximately $188 million or $150 million, respectively. 

Future production and development costs, which include dismantlement and restoration expense, are computed by 
estimating the expenditures to be incurred in developing and producing the proved crude oil and natural gas reserves 
at the end of the year, based on year-end costs, and assuming continuation of existing economic conditions. 

Future development costs include amounts that we expect to spend to develop proved undeveloped reserves of 
$900 million in 2010, $800 million in 2011 and $500 million in 2012. 

Future income tax expense is computed by applying the appropriate year-end statutory tax rates to the estimated 
future pretax net cash flows relating to proved crude oil and natural gas reserves, less the tax bases of the properties 
involved. Future income tax expense gives effect to tax credits and allowances, but does not reflect the impact of 
general and administrative costs and exploration expenses of ongoing operations.

Item 9.   Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

None. 

Item 9A.  Controls and Procedures 

Evaluation of Disclosure Controls and Procedures 

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed 
by us in the reports we file or furnish to the SEC under the Securities Exchange Act of 1934, as amended, is 
recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms, and 
that information is accumulated and communicated to management, including our principal executive officer and 
principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. 

Our principal executive officer and principal financial officer have evaluated the effectiveness of our “disclosure 
controls and procedures,” as such term is defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 
1934, as amended, as of the end of the period covered by this Annual Report on Form 10-K. Based upon their 
evaluation, they have concluded that our disclosure controls and procedures are designed and effective to ensure 
that information required to be disclosed in the reports that we file or furnish under the Securities Exchange Act of 
1934, as amended, is recorded, processed, summarized and reported within the time periods specified by the SEC's 
rules and forms and that information is accumulated and communicated to management, including our principal 
executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. 

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and 
procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance 
that the objectives of the control system will be met. In addition, the design of any control system is based in part 
upon certain assumptions about the likelihood of future events and the application of judgment in evaluating the cost-
benefit relationship of possible controls and procedures. Because of these and other inherent limitations of control 
systems, there is only reasonable assurance that our controls will succeed in achieving their goals under all potential 
future conditions. 

Management’s Annual Report on Internal Control over Financial Reporting 

The management report called for by Item 308(a) of Regulation S-K is incorporated herein by reference to 
Management’s Report on Internal Control over Financial Reporting, included in Item 8. Financial Statements and 
Supplementary Data. 

The independent auditor’s attestation report called for by Item 308(b) of Regulation S-K is incorporated herein by 
reference to Report of Independent Registered Public Accounting Firm (Internal Control Over Financial Reporting), 
included in Item 8. Financial Statements and Supplementary Data. 

Changes in Internal Control over Financial Reporting 

Our management is also responsible for establishing and maintaining adequate internal controls over financial 
reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended. Our 
internal controls were designed to provide reasonable assurance as to the reliability of our financial reporting and the 
preparation and presentation of the consolidated financial statements for external purposes in accordance with 
accounting principles generally accepted in the United States. 

Because of its inherent limitations, internal control over financial reporting may not detect or prevent misstatements. 
Projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate. 

Our management has assessed the effectiveness of our internal controls over financial reporting as of December 31, 
2009. Based on our assessment, our internal controls over financial reporting were effective. There were no changes 
in internal controls over financial reporting that occurred during the most recent fiscal quarter that have materially 
affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
