Potential

Access to new hydrocarbon resources is a 
critical element for organic growth. Our exploration
success in West Africa and the deepwater Gulf 
of Mexico, combined with a huge inventory of
development projects in onshore basins of the U.S.,
creates tremendous possibilities for the future.

Expand

We extend our asset portfolio 
with selective property and corporate 
acquisitions, while our new ventures team 
searches for new opportunities worldwide. Our
acreage positions in the New Albany shale, Piceance
basin and Niobrara plays continue to build as they
develop into core areas. Exploration prospects
offshore Israel and Suriname are also 
important in broadening our portfolio.

2007 was a special year for Noble Energy in many ways. We had the opportunity to

celebrate our company’s 75th anniversary as we looked back with pride on the many

accomplishments since our founding by Lloyd Noble in 1932. We also celebrated the

many financial and operational successes of 2007. Our shareholders participated in

our success, as our share price increased 62 percent during the year. Additionally,

Noble Energy’s growth and performance resulted in our addition to the prestigious

S&P 500 index during the year.

It was clearly a year of tremendous accomplishments. We achieved record earnings

totaling approximately $944 million, a 39 percent increase over our previous record

in 2006. It was also a year of record volumes which averaged 199 thousand barrels

of oil equivalent per day (MBoepd), a 13 percent increase over 2006 after adjusting

for the company’s sale of the Gulf of Mexico shelf assets. We continued to focus on

cost efficiency throughout our business, allowing us once again to keep our unit cash

costs in the best quartile among our peers. Our proven reserves at the end of 2007

reached  a  record  of  880  million  barrels  of  oil  equivalent  (MMBoe), up  over  five

percent from the prior year. During 2007, we invested $1.7 billion in exploration and

development projects, allowing us to replace 166 percent of our volumes with new

reserves at under $15 per barrel of oil equivalent (BOE).

We achieved a number of key objectives related to our
exploration  and  production  programs. Early  in  the
year, we resumed our West Africa exploration program
after  waiting  for  over  a  year  on  the  upgrade  of  a
deepwater drillship.The 2007 exploration program in
West Africa  was  one  of  the  most  significant  in  our
company’s history and resulted in six successful wells
out  of  seven  drilled. At  the  end  of  this  program, we
not  only  appraised  our  2005  Belinda  discovery, but
also  discovered  the  Benita, Yolanda  and Yoyo  fields.
Belinda, Benita and Yolanda are located in Equatorial
Guinea  and Yoyo  is  located  just  across  the  border 
in Cameroon. These new fields will be an important 
part  of  our  growth  for  many  years  to  come.
Other  important  2007  events  that  occurred  in  our
international  business  included  initial  gas  sales  to  a
new  liquefied  natural  gas  (LNG)  plant  in  Equatorial
Guinea and the startup of the Dumbarton field in the
North Sea. In addition, our natural gas sales in Israel
grew  19  percent  in  2007  and  has  grown  every  year
since we started producing in 2004.

In the United States (U.S.), we continued a very active
investment  program  in  the  Rocky  Mountains.
Wattenberg, our  largest  onshore  field, contains  an
inventory  of  thousands  of  lower  risk  development
projects, allowing  us  to  grow  its  production  and
proven reserves. Elsewhere in the Rocky Mountains,
we accelerated the drilling programs in the Piceance
basin  and  Niobrara  plays. Both  areas  showed
significant drilling success, and we are expecting more
growth  in  2008. We  continued  our  exploration  and
development work in the deepwater Gulf of Mexico.
During the year, we carried out a number of projects
at our existing deepwater fields that not only helped
maintain  their  production, but  also  added  new
resources. With  our  partner, we  discovered  Isabela  in
the  deepwater  offshore  Louisiana. Following  the
discovery, we acquired offset acreage and are planning
additional drilling in 2008. We were also a successful

bidder in the 2007 Central Gulf lease sale, allowing us
to add several deepwater prospects to our inventory.

Our  overall  business  model  remains  unchanged. It  is
simple and designed to help Noble Energy thrive in a
variety of environments.The foundation is a portfolio
of high-quality assets that are efficient and long-lived
producers, yield  high  investment  returns, and/or
possess  large  inventories  of  future  development
opportunities. These lower risk development projects
generate  sustainable  and  durable  near-term  growth.
Our exploration program has evolved into one that is
almost entirely focused on significant and high impact
opportunities. We  supplement  our  portfolio  with
acquisitions  of  both  producing  properties  and
prospective acreage. This business model allows us to
maintain  capital  discipline, while  still  growing  our
company. In  times  of  strong  commodity  prices, it
allows  us  to  generate  free  cash  flow  to  maintain  our
financial strength and provides substantial capacity to
fund unique and unanticipated opportunities.

As we make plans to move Noble Energy to the next
level of performance, our thoughts center on how to
further  improve  our  portfolio  and  processes. The
energy  industry  is  in  a  very  dynamic  period  where
innovative ideas are constantly opening up new areas
for growth. We pursue a diversified portfolio of assets
balanced  between  U.S. and  international  operating
areas. We are also looking for opportunities to add to
this portfolio and dispose of assets that are no longer
core to us. Over the past year, we have expanded our
U.S. positions  in  the  New  Albany  shale, Piceance 
basin  and  Niobrara  plays  and  announced  the  sale  of 
our  properties  in  Argentina  –  all  changes  that  are
consistent  with  our  overall  portfolio  management
strategies. Our  exploration  processes  continue  to
evolve and improve through the application of better
techniques and new technology. This has given us the
confidence to grow our exploration program, leading

us to incredible success in West Africa this past year.We
have built a new ventures program that is designed to
leverage  our  exploration  expertise  by  identifying
growth  opportunities, sometimes  in  areas  virtually
unexplored by our industry.“Next level” thinking also
applies to new drilling techniques.We have identified
and  applied  best  drilling  practices, allowing  us  to
substantially  reduce  costs  and/or  improve  well
performance. Once  again, our  West  Africa  drilling
program  provides  a  significant  example  where  the
drilling  time  to  target  depth  was  reduced  by  50
percent, yielding substantial savings in drilling costs. In
the Wattenberg field, we began testing a new drilling
technique utilizing coiled tubing that reduced drilling
times  for  new  wells  by  almost  half. In  the  Piceance
basin, we  are  using  rigs  that  are  better  able  to  drill
multiple wells off single drill pads, thus reducing time,
cost  and  environmental  impact. We  are  also  making
significant  investments  in  new  business  systems  that
give us better efficiency and flexibility as we account
for and analyze our performance.

Our programs for 2008 are expected to build on the
solid  foundation  established  in  2006  and  2007. Our
capital  investment  program  for  2008  has  been  set  at
$1.6  billion  and  focuses  on  our  core  areas  that  have
yielded  our  growth  in  recent  years. Approximately
three-quarters of our capital will be directed towards
development projects and one-quarter to exploration.
In  the  Rocky  Mountains, we  again  plan  to  invest
heavily  in  the  Wattenberg, Piceance  and  Niobrara
areas  to  take  advantage  of  their  huge  inventories  of
lower  risk  development  projects. We  also  plan  to
further test our New Albany shale acreage in Southern
Indiana, where  we  recently  brought  new  wells  on
production. In  the  deepwater  Gulf  of  Mexico, we 
plan  to  participate  in  several  exploration  prospects 
and  bring  on  new  production  at  South  Raton 
and  Ticonderoga. We  are  planning  for  ongoing
development  work  at  our  core  Mid-continent  fields

and  for  the  expansion  of  our  drilling  programs  in 
East Texas.

Our  international  investment  program  will  remain
active  in  2008. As  a  follow-up  to  the  outstanding
exploration success we experienced in West Africa in
2007, we  are  planning  for  further  appraisal  and
exploration  drilling  this  year, as  well  as  beginning 
the important engineering work necessary to prepare
for  the  development  of  our  recent  discoveries  there.
In  addition, we  are  planning  to  test  important
exploration prospects offshore Israel and Suriname. It
will  be  Noble  Energy’s  first  well  in  Suriname. In
Equatorial  Guinea, we  expect  continued  production
growth in 2008 as a result of a full year of natural gas
sales to the LNG plant. In late 2007, we approved the
next phase of development of the Dumbarton field in
the North Sea. Israel is continuing to build its natural
gas  pipeline  infrastructure,
thus  expanding  our
customer base and increasing the demand for natural
gas. Also  scheduled  for  approval  in  2008  is  the
expansion of the Cheng Dao Xi field in the Bohai Bay
of China.This will be the first major expansion of the
field since it first started up in early 2003.

We  are  pleased  with  our  performance  and  are  truly
excited about what the future holds for Noble Energy.
Our  underlying  asset  portfolio  shows  great  strength
and  durability  as  it  provides  strong  production  and 
a  large  inventory  of  investment  opportunities. We
continue  to  build  our  exploration  inventory  by
seeking  out  new  areas  that  will  benefit  from  the
application of innovative technology and processes. At
the same time, we remain receptive to new ideas and
opportunities that will help propel us to the next level
of performance. We have come a long way in a very
short period of time, but there is tremendous potential
to further expand in the future.

Our  progress  and  performance  is  clearly  the  result 
of  incredible  dedication  and  hard  work  exhibited  by
our  employees. Noble  Energy  employees  remain
committed  to  efficiently  finding, developing  and
producing important energy supplies, while providing
superior returns to our shareholders.These employees
are  also  dedicated  to  minimizing  the  impacts  on  the
environment, preserving the safety of all involved and
complying with complex laws and regulations. I could
not be more proud of their significant achievements,
and  how  they  conduct  Noble  Energy’s  business
throughout the world.

We offer our thanks to Bruce A. Smith, who resigned
from  our  board  in  2008. Bruce  joined  the  board  in
2002  and  was  extremely  helpful  as  we  took  Noble
Energy through an important transformation in recent
years.We welcome Scott D. Urban to our board. Scott
joined  us  in  2007  and  was  previously  an  executive
with Amoco and its successor BP.

On a final note, all of us at Noble Energy mourn the
sudden  and  tragic  passing  of  Robert  K. Burleson,
our  Senior  Vice  President  of  Administration  and
Marketing. Bob is greatly missed as a friend as well as
a  significant  contributor  to  our  company. 2007  also
saw the passing of Mary Jane Noble, wife of the late
Sam  Noble. As  we  complete  our  75th  year, we  are
reminded of the immense legacy the Noble family has
left us.

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

PART I 

This  Annual  Report  on  Form 10-K  and  the  documents  incorporated  herein  by  reference  contain  forward-looking 
statements based on expectations, estimates and projections as of the date of this filing. These statements by their 
nature are subject to risks, uncertainties and assumptions and are influenced by various factors. As a consequence, 
actual results may differ materially from those expressed in the forward-looking statements. For more information, 
see Item 1A. Risk Factors—Disclosure Regarding Forward-Looking Statements of this Form 10-K. 

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  and 
natural  gas  since  1932.  In  this  report,  unless  otherwise  indicated  or  where  the  context  otherwise  requires, 
information  includes  that  of  Noble  Energy  and  its  subsidiaries.  Exploration  activities  include  geophysical  and 
geological  evaluation  and  exploratory  drilling  on  properties  for  which  we  have  exploration  rights.  We  operate 
throughout major basins in the United States (“US”) including Colorado’s Wattenberg field and Piceance basin, the 
Mid-continent  area  of  western  Oklahoma  and  the  Texas  Panhandle,  the  San  Juan  basin  in  New  Mexico,  the  Gulf 
Coast  and  the deepwater Gulf  of  Mexico.  In  addition, we  conduct  business  internationally  in  China, Ecuador,  the 
Mediterranean Sea, the North Sea, West Africa (Equatorial Guinea and Cameroon) and in other areas.     

Strategy 

We are a worldwide producer of crude oil and natural gas. Our strategy is to achieve growth in earnings and cash 
flow  through  the  development  of  a  high  quality  portfolio  of  producing  assets  that  is  balanced  between  US  and 
international projects. Strategic acquisitions (Patina Oil & Gas Corporation (“Patina”) in 2005 and U.S. Exploration 
Holdings, Inc. (“U.S. Exploration”) in 2006), along with additional capital investment  have resulted in substantial 
growth in the last five years. Acquisitions and capital investment, combined with the sale of non-core assets, have 
allowed us to achieve a strategic objective of enhancing our US asset portfolio, resulting in a company with assets 
and  capabilities  that  include  growing  US  basins  coupled  with  a  significant  portfolio  of  international  properties. 
Crude oil and natural gas sales volumes have doubled since 2003. Our reserve base, which includes both US and 
international sources at 58% US and 42% international, has almost doubled in the same period. We are now a larger, 
more  diversified  company  with  greater  opportunities  for  both  US  and  international  growth.  See  Item  6.  Selected 
Financial Data for additional financial and operating information for fiscal years 2003-2007. 

Proved Reserves 

As of December 31, 2007, we had estimated proved reserves of 3.3 Tcf of natural gas and 329 MMBbls of crude oil. 
On a combined basis, these proved reserves were equivalent to 880 MMBoe, an increase of 5% over the prior year. 
At December 31, 2007, 74% of reserves were proved developed reserves.

Proved  oil  and  gas  reserves  are  the  estimated  quantities  of  crude  oil,  natural  gas  and  natural  gas  liquids  which 
geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known 
reservoirs  under  existing  economic  and  operating  conditions,  i.e.,  prices  and  costs  as  of  the  date  the  estimate  is 
made. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not 
on escalations based upon future conditions. For additional information regarding estimates of crude oil and natural 
gas reserves, including estimates of proved and proved developed reserves, the standardized measure of discounted 
future  net  cash  flows,  and  the  changes  in  discounted  future  net  cash  flows,  see  Item  8.  Financial  Statements  and 
Supplementary  Data—Supplemental  Oil  and  Gas  Information  (Unaudited)  and  Item  7.  Management’s  Discussion 
and  Analysis  of  Financial  Condition  and  Results  of  Operations—Critical  Accounting  Policies  and  Estimates—
Reserves. 

Engineers in our Houston, Denver and London offices prepare all reserve estimates for our different geographical 
regions. These reserve estimates are reviewed and approved by senior engineering staff and division management 
with final approval by the Director of Asset Development and certain members of senior management. During each 
of the years 2007, 2006 and 2005, we retained Netherland, Sewell & Associates, Inc. (“NSAI”), independent third-
party  reserve  engineers,  to  perform  reserve  audits  of  proved  reserves.  A  “reserve  audit”,  as  we  use  the  term,  is  a 
process involving an independent third-party engineering firm’s visits, collection of any and all required geologic, 
geophysical,  engineering  and  economic  data,  and  such  firm’s  complete  external  preparation  of  reserve  estimates. 
Our use of the term “reserve audit” is intended only to refer to the collective application of the procedures which 
NSAI was engaged to perform. The term “reserve audit” may be defined and used differently by other companies. 

The reserve audit for 2007 included a detailed review of 16 of our major international, deepwater Gulf of Mexico 
and US fields, which covered approximately 71% of US proved reserves and 96% of international proved reserves 
(81%  of  total  proved  reserves).  The  reserve  audit  for  2006  included  a  detailed  review  of  14  of  our  major 
international,  deepwater  Gulf  of  Mexico  and  US  fields,  which  covered  approximately  80%  of  our  total  proved 
reserves. The reserve audit for 2005 included a detailed review of 11 of our major international, deepwater Gulf of 
Mexico and US fields, which covered approximately 72% of our total proved reserves.  

In  connection  with  the  2007  reserve  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  reserve  quantities,  future 
producing  rates,  future  net  revenue,  and  the  present  value  of  such  future  net  revenue.  NSAI  also  examined  our 
estimates with respect to reserve categorization, using the definitions for proved reserves set forth in Regulation S-X 
Rule 4-10(a) and  subsequent  Securities  and  Exchange  Commission  (“SEC”)  staff  interpretations  and  guidance.  In 
the conduct of the reserve 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,  2007,  based 
upon its evaluation. Its 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. 

The  fields  that  NSAI  audits  include  our  most  significant  fields  and  are  chosen  by  senior  engineering  staff  and 
division  management  with  final  approval  by  the  Director  of  Asset  Development  and  certain  members  of  senior 
management. We usually include all deepwater Gulf of Mexico fields, all international fields that require reports by 
requirement of the host government, all fields that require sanctioning by our Board of Directors, and other major 
fields. No significant fields were excluded from the December 31, 2007 reserve audit. 

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 21,966 
MBoe  above  to  16,882  MBoe  below  as  compared  with  our  estimates.  On  a  percentage  basis,  the  NSAI  field 
estimates ranged from 9% above our estimates to 42% 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%. At December 31, 2007, reserves differences, in the aggregate, were less than 13,200 MBoe, or 2%. 

Since January 1, 2007, no crude oil or natural gas reserve information has been filed with, or included in any report 
to any federal authority or agency other than the SEC and the Energy Information Administration (“EIA”) of the US 
Department of Energy. We file Form 23, including reserve and other information, with the EIA. 

Acquisition and Divestiture Activities 

We maintain an ongoing portfolio optimization program. 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. 

In December 2007, we entered into an agreement to sell our interest in Argentina for a sales price of $117.5 million, 
effective July 1, 2007. We expect the sale, which is subject to regulatory and partner approvals, to close in 2008. 
Crude oil reserves for the Argentina properties totaled 7 MMBbls at December 31, 2007. 

In  2006,  we  sold  all  of  our  Gulf  of  Mexico  shelf  properties  except  for  the  Main  Pass  area,  which  is  undergoing 
redevelopment studies. 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. Deepwater Gulf of Mexico and Gulf Coast 
onshore areas remain core areas and are more aligned with our long-term business strategies. See Item 8. Financial 
Statements and Supplementary Data—Note 3—Acquisitions and Divestitures. 

In 2006, we acquired U.S. Exploration, a privately held corporation, for $412 million plus liabilities assumed. U.S. 
Exploration’s  reserves  and  production  are  located  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% of the reserves were proved developed and 55% of the reserves were 
natural gas. Proved crude oil and natural gas properties were valued at $413 million and unproved properties were 
valued  at  $131 million.  See  Item  8.  Financial  Statements  and  Supplementary  Data—Note  3—Acquisitions  and 
Divestitures. 

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 provide 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% of the reserves were proved developed and 67% of the reserves were natural gas. Proved crude oil and 
natural gas properties were valued at $2.6 billion and unproved properties were valued at $1.1 billion. See Item 8. 
Financial Statements and Supplementary Data—Note 3—Acquisitions and Divestitures.

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. We also own natural gas processing plants 
and natural gas gathering and other crude oil and natural gas related pipeline systems. 

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 have  significantly  increased  the  breadth of  our onshore  operations,  especially  in  the  Rocky  Mountain 
and Mid-continent areas. These two acquisitions have provided us with a multi-year inventory of exploitation and 
development  opportunities.  In  2007,  we  continued  to  expand  our  acreage  position  with  the  acquisition  of 
approximately 290,000 net acres in the Piceance, Niobrara, and New Albany Shale areas. US operations accounted 
for  58%  of  our  2007  consolidated  sales  volumes  and  58%  of  total  proved  reserves  at  December 31,  2007. 
Approximately  60%  of  the  proved  reserves  are  natural  gas  and  40%  are  crude  oil.  Our  onshore  US  portfolio  at 
December 31, 2007 included 1,308,823 gross developed acres and 1,234,858 gross undeveloped acres. We also hold 
interests in 97 offshore blocks in the Gulf of Mexico. In 2008, we plan to invest approximately $1.2 billion, or 74%, 
of budgeted capital in the US. 

Sales of production and estimates of proved reserves for our significant US operating areas were as follows:

Northern Region—The Northern region consists of our operations in the Rocky Mountain area, which includes the 
D-J (Wattenberg field), San Juan, Wind River, and Piceance basins, as well as the Niobrara, Bowdoin and Siberia 
Ridge fields. The addition of Patina and U.S. Exploration assets, particularly in the Wattenberg field, combined with 
our legacy operations in the Bowdoin field, the Niobrara trend, the Wind River basin and Piceance basin, have made 
the  Rocky  Mountains  one  of  our  core  operating  areas.  We  are  currently  running  13  drilling  rigs  and  24 
completion/workover  units. We  plan  to  invest  approximately  $744  million,  or  62%  of  budgeted US  capital  in  the 
Northern region during 2008. 

Wattenberg  Field—The  Wattenberg  field  (approximately  97%  operated  working  interest),  our  largest  US  asset, 
continues to grow production and reserves. In 2007, sales of production from this field accounted for 36% of total 
US  sales  volumes.  Wattenberg  field  proved  reserves  accounted  for  50%  of  US  proved  reserves  at  December 31, 
2007.  

We acquired working interests in the Wattenberg field through the Patina Merger in 2005 and acquisition of U.S. 
Exploration  in  2006.  Located  in  the  D-J basin  of  north  central  Colorado,  the Wattenberg field provides us  with a 
substantial  future  project  inventory.  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, with 99.8% of the wells drilled in 2007 encountering sufficient quantities of reserves to be completed as 
economic producers. In May 1998, the Colorado Oil and Gas Conservation Commission (“COGCC”) adopted the 
“Greater Wattenberg Area Special Well Location Rule 318A” which allows all formations in the Wattenberg field to 
be drilled, produced and commingled from any or all of ten “potential drilling locations” on a 320-acre parcel. A 
“commingled” well is one which produces crude oil from two or more formations or zones through a common string 
of casing and tubing. In December 2005, the COGCC amended Rule 318A providing for an effective well density of 
one well per 20 acres in a designated portion of the Greater Wattenberg Area to more effectively drain the reservoir. 
The amendment applies only to the Niobrara, Codell and J-Sand formations and became effective in March 2006. 

We  are  currently  running  seven  drilling  rigs  and  17  completion  units  in  the  Wattenberg  field.  Our  current  field 
activities  are  focused primarily  on  the development  of  J-Sand,  Codell  and Niobrara  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. During 2007, we drilled or participated in 508 development wells, with a 99.8% success

rate,  and  added  approximately  244  Bcfe  of proved reserves  in  the Wattenberg  field.  Approximately  58%  of  these 
reserve additions were natural gas. We also grew production from an average of 227 MMcfe per day for 2006 to 240 
MMcfe  per  day  for  2007.  We  plan  to  drill  approximately  480  wells  in  2008  (of  which  337  will  be  combination 
Codell/Niobrara new drills).  We also plan to participate in 120 non-operated drilling projects in 2008.  We have a 
substantial  project  inventory  remaining  and  plan  to  perform  approximately  340  projects  including  refractures, 
trifractures, and recompletions during 2008. 

Other Rocky Mountain areas include: 

Niobrara Trend—The Niobrara trend (approximately 87% operated working interest) is located in eastern Colorado 
and  extends  into  Kansas  and  Nebraska.  During  2007,  we  expanded  our  acreage  position  with  the  acquisition  of 
160,000 net acres.  We are currently running two drilling rigs and three completion units.  During 2007, we drilled 
or participated in 125 wells with a 79% success rate, and our activity resulted in the addition of 19 Bcfe of proved 
reserves. We plan to drill 300 wells in 2008. 

Piceance Basin—The Piceance basin in western Colorado (approximately 96% operated working interest) is another 
rapidly growing area for us. During 2007, we added 10,500 net acres to our position. We are currently running four 
drilling rigs and three completion units.  We drilled or participated in 55 development wells during 2007, 100% of 
which were successful, and our activity resulted in the addition of 83 Bcfe of proved reserves. We plan to drill over 
100 wells during 2008.  

Other—We  are  also  active  in  the  Bowdoin  field  (approximately  60%  operated  working  interest),  located  in  north 
central Montana; the San Juan basin (approximately 81% operated working interest), located in northwestern New 
Mexico  and  southwestern  Colorado;  and  the  Wind  River  basin  (approximately  56%  operated  working  interest), 
located in central Wyoming. During 2007 we drilled or participated in a total of 56 development wells in these areas, 
100% of which were successful. We plan to drill approximately 60 wells and recomplete 190 wells during 2008. 

Southern Region—The Southern region includes the Gulf Coast onshore, West and East Texas, Louisiana, and the 
deepwater Gulf of Mexico, as well as the Mid-continent area (the Texas Panhandle and parts of Oklahoma, Kansas, 
Arkansas, Illinois and Indiana). The Gulf Coast and deepwater Gulf of Mexico are core US operating areas. During 
2006,  we  sold  all  of  our  Gulf  of  Mexico  shelf  properties  except  for  the  Main  Pass  area.  The  sale  of  our  shelf 
properties allows us to migrate future investments and growth from the Gulf of Mexico shelf to the deepwater Gulf 
of Mexico which we believe is an area of higher potential. We plan to invest approximately $460 million, or 38% of 
budgeted US capital, in the Southern region during 2008, with approximately 67% in the deepwater Gulf of Mexico, 
and the remainder to the Gulf Coast and the Mid-continent areas. 

Deepwater Gulf of Mexico—Deepwater Gulf of Mexico accounted for 22% of 2007 US sales volumes and 7% of US 
proved reserves at December 31, 2007. During 2007, we continued to focus on the growth of our deepwater Gulf of 
Mexico  business  highlighted  by  a  successful  exploration  discovery  at  Isabela  and  a  successful  sidetrack-appraisal 
well at our 2006 Raton discovery.  We also completed successful development drilling programs in our Ticonderoga 
and Swordfish fields. Deepwater Gulf of Mexico activity resulted in proved reserve additions of 12 MMBoe during 
2007. Participation in the 2007 Central Gulf of Mexico Outer Continental Shelf Sale resulted in our being awarded 
eight new deepwater Gulf of Mexico leases totaling $50 million. 

At  year-end,  development  planning  was  underway  for  Isabela  (Mississippi  Canyon  Block  562,  33%  working 
interest). We have also acquired an interest in adjacent acreage with additional exploration potential on Mississippi 
Canyon Blocks 519 and 563 (23.25% working interest).  We plan to drill a well on Block 519 (Santa Cruz Prospect) 
in  2008  pending  rig  availability.    In  total  there  are  three  prospects  on  the  combined  leasehold  that,  conceptually, 
would be co-developed in a subsea tieback to an existing production facility. 

Other  2007  exploration  drilling  included  the  Mississippi  Canyon  Block  568  #1  (Robusto  Prospect,  20%  working 
interest)  and  the  East  Breaks  Block  465  #1  (Lost  Ark  South  Prospect,  98.4%  working  interest),  neither  of  which 
encountered hydrocarbons in commercial quantities.   

During 2007 we saw an extremely active deepwater Gulf of Mexico development program. At our Raton project in 
Mississippi Canyon Block 248 (66.67% operated working interest), we successfully sidetracked and completed the 
248 #1 discovery well drilled in 2006.  At year-end the project had moved into the development stage and is slated 
for subsea tieback and first production in the second quarter of 2008.  

At  our  operated  Swordfish  project  (85%  working  interest),  we  drilled  and  completed  a  sidetrack  to  Viosca  Knoll 
Block 917 #1 well and began gas production from this well at year end.   At the Ticonderoga development in Green 

6 

 
Canyon Block 768 (50% working interest, non-operated),  the #3 and #1 ST4 wells were drilled and completed to 
extend and enhance production from the field.  Both are slated for first production in the first quarter of 2008. 

At  the  Lost  Ark  project  in  East  Breaks  Blocks  421  and  464  (48.4%  operated  working  interest),  the  421  #1  well, 
which had reached the end of its productive life, was plugged and abandoned, and the 464 #1 well was completed 
and put on production to develop the remaining reserves at the field.   

We  are  currently  evaluating  a  possible  sidetrack-appraisal  well  to  be  drilled  at  the  Raton  South  oil  discovery  in 
Mississippi  Canyon  Block  292  during  late  2008  (originally  drilled  in  2006).  The  Redrock  natural  gas/condensate 
discovery,  also  drilled  in  2006,  is  currently  considered  a  co-development  candidate  to  a  successful  sidetrack-
appraisal  well  at  Raton  South.  Additional  key  exploration  activity  planned  for  2008  includes  a  well  at  the 
Mississippi Canyon Block 948, Gunflint prospect, (50% working interest), in the second half of 2008.     

Mid-continent—A  significant  area  of  activity  in  Mid-continent  is  the  Granite  Wash  development,  located  in  the 
Texas Panhandle. We drilled or participated in 53 development wells in 2007, 100% of which were successful. The 
potential  for  horizontal  drilling  is  currently  being  evaluated.    Another  significant  area  in  Mid-continent  is  the 
ongoing  Southern  Oklahoma  development.  In  2007  we  drilled  or  participated  in  45  wells  resulting  in  additional 
incremental production of 1,515 Boepd.  

In  addition,  we  continue  to  selectively  increase  our  acreage  position  in  resource  plays,  including  shale  plays.  We 
have  accumulated  over  179,000  acres  in  the  New  Albany  Shale.  During  2007,  we  drilled  16  New  Albany  Shale 
wells. Currently nine are producing and seven are in the progress of pipeline connection. The Paxton facility, which 
we operate, will serve the majority of wells in the Paxton field. We plan to have an active drilling program during 
2008.  

Other Mid-continent areas include parts of Texas, Oklahoma, Kansas, Illinois, Indiana and Arkansas. During 2007, 
we drilled or participated in a total of 33 wells.  We plan to drill or participate in 60 wells in the Mid-continent area 
during 2008. 

Gulf Coast Onshore—During late 2007, we began a six well program at Oliver Creek in Shelby County, Texas to 
develop  the  Travis  Peak  reservoir  as  well  as  test  deeper  Cotton  Valley  horizons.  We  have  completed  one  Travis 
Peak well and are currently completing the second Travis Peak well.  The deeper Cotton Valley horizons are being 
tested in two additional wells currently being drilled or completed.  Two additional wells remain in the current six 
well program.  Additional drilling is planned for later in 2008. 

International 

International operations are significant to our business, accounting for 42% of consolidated sales volumes in 2007 
and  42%  of  total  proved  reserves  at  December 31,  2007.  International  proved  reserves  are  approximately  67% 
natural  gas  and  33%  crude  oil.  Operations  in  Equatorial  Guinea,  Cameroon,  Ecuador,  China  and  Suriname  are 
conducted in accordance with the terms of production sharing contracts. In 2008, we plan to invest approximately 
$392 million, or 24%, of budgeted capital in our international locations.

West  Africa  (Equatorial  Guinea  and  Cameroon)—Operations  in  West  Africa  accounted  for  46%  of  2007 
consolidated  international  sales  volumes  and  65%  of  international  proved  reserves  at  December 31,  2007.  At 
December 31,  2007,  we  held  45,203  gross  developed  acres  and  850,197  gross  undeveloped  acres  in  Equatorial 
Guinea and 1,125,000 gross undeveloped acres in Cameroon. 

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 (located on Bioko Island), and an 
onshore LPG processing plant where additional condensate is produced. The methanol plant was originally designed 
to  produce commercial  grade  methanol  at a  rate of  2,500  MTpd gross. As  a  result of various  upgrade  efforts,  the 
plant is now 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 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 northwestern Europe. We sell our share of condensate produced in the Alba field and from 
the LPG plant under short-term contracts at market-based prices.

Our exploration activities in West Africa center around Blocks O and I offshore Equatorial Guinea and the PH-77 
license offshore the Republic of Cameroon. We are the technical operator on Blocks O and I (45% and 40% working 
interest, respectively) and the operator on the PH-77 license (50% working interest). We drilled seven wells in the 
area during 2007 resulting in three new discoveries and three successful appraisal wells: 

Benita – The I-1 well, testing the Benita prospect, resulted in a new gas-condensate discovery on Block I.  

Benita appraisal – The I-2 appraisal well on Block I encountered crude oil. Testing has been deferred in order to 
secure an additional drilling rig that will be capable of further appraisal drilling downdip in the Benita oil column, 
which is in deeper water. It is expected that a rig will be available for drilling the additional Benita appraisal well in 
the first quarter of 2008. 

Yolanda – The I-3 well, testing the Yolanda prospect, resulted in another new gas-condensate discovery on Block I. 

I-4 – The I-4 well on Block I was a successful well on trend with the 2005 Belinda discovery on Block O.   

Adriana – The O-2 exploration well (the Adriana Southwest prospect) on Block O offshore Equatorial Guinea did 
not contain commercial hydrocarbons. The well was plugged and abandoned.  

Belinda appraisal – The O-3 appraisal well on Block O successfully extended the Belinda discovery by establishing 
significant downdip resources.  

YoYo – The YoYo-1 well resulted in a new gas-condensate discovery on the PH-77 license offshore the Republic of 
Cameroon.  Additional  appraisal  work  is  necessary  to  verify  the  areal  extent  of  the  discovery.  There  was  also  a 
secondary target, in which commercial hydrocarbons were not found. 

In 2008, we plan to have an active exploration and appraisal drilling program for both Blocks I and O as we assess 
our options to commercialize our discoveries in the region.  

Effective  November 2006,  the  government  of  Equatorial  Guinea  enacted  a  new  hydrocarbons  law  (the  “2006 
Hydrocarbons Law”) governing petroleum operations in Equatorial Guinea. The governmental agency responsible 
for the energy industry was given the authority to renegotiate any contract for the purpose of adapting any terms and 
conditions that are inconsistent with the new law. At this time we are uncertain what economic impact this law will 
have on our operations in Equatorial Guinea. 

North Sea—Operations in the North Sea (the Netherlands, Norway and the UK) comprise another core international 
asset,  and  we  have  been  conducting  business  there  since  1996.  We  have  working  interests  in  23  licenses  with 
working  interests  ranging  from  7%  to  100%.  We  are  the  operator  of  four  blocks,  covered  by  three  licenses.    The 
North  Sea  accounted  for  17%  of  2007  consolidated  international  sales  volumes  and  8%  of  international  proved 
reserves  at  December 31,  2007.  At  December 31, 2007,  we  held  48,230  gross  developed  acres  and  836,625  gross 
undeveloped acres. 

In January 2007, production began at the non-operated Dumbarton development (30% working interest) in Blocks 
15/20a and 15/20b in the UK sector of the North Sea. Dumbarton, a re-development of the Donan field, includes a 
subsea tie-back to the GP III, a floating production, storage and offloading vessel in which we own a 30% interest. 
We  expect  to  continue  the  development  of  Dumbarton  in  2008  with  phases  2a  and  2b.  In  addition,  we  will 
participate in the development of the Lochranza prospect, which will also consist of a subsea tie-back to the GP III. 

Exploration efforts continued in 2007 as we and our partners successfully completed an exploratory appraisal well 
on  the  Flyndre  Block  (22.5%  working  interest)  in  the  UK  sector  of  the  North  Sea.    We  also  participated  in  a 
successful exploration well at Selkirk in Block 22/22b P233 (30.5% working interest), also in the UK sector of the 
North Sea.    

Mediterranean  Sea  (Israel)—Operations  in  Israel  accounted  for  23%  of  2007  consolidated  international  sales 
volumes and 14% of international proved reserves at December 31, 2007. At December 31, 2007, we held 123,552 
gross developed  acres  and 1,183,479  gross undeveloped  acres  located between 10  and  60  miles  offshore Israel  in 
water depths ranging from 700 feet to 5,500 feet. Our leasehold position in Israel includes one preliminary permit, 
two leases and three licenses, and we are the operator. 

We have been operating in the Mediterranean Sea, offshore Israel, since 1998, and our 47% working interest in the 
Mari-B  field  is  one  of  our  core  international  assets.  The  Mari-B  field  is  the  first  offshore  natural  gas  production 
facility in the State of Israel. During 2007, we completed the Mari-B #7, which is designed to produce twice what a 

9 

 
normal  Mari-B  well  produces  in  Israel,  or  approximately  200  MMcfpd  of  natural  gas.  The  Mari-B#7  well  has 
resulted in peak field deliverability of 600 MMcfpd.   

Natural  gas  sales  began  in  2004  and  have  been  increasing  steadily  as  Israel’s  natural  gas  infrastructure  has 
developed. In 2007, our gas sales volumes increased 19% over 2006 volumes and 67% over 2005 volumes. During 
2007 we completed construction of a permanent onshore receiving terminal in Ashdod for distribution of natural gas 
from the Mari-B field to purchasers. Commissioning of the terminal is expected in early 2008. We also began selling 
natural gas to a desalinization plant and a paper mill in 2007. Additional natural gas sales in 2008 will depend on the 
timing  of  onshore  pipeline  construction  and  plant  conversion,  which  should  allow  the  Israel  Electric  Corporation 
Limited power plants at Gezer and Hagit to consume gas.  

Exploration activities continue in Israel. We are in the process of securing a rig and intend to drill one exploration 
well testing the Tamar prospect (33% working interest), offshore northern Israel, in 2008.  

Ecuador—Operations  in  Ecuador  accounted  for  5%  of  2007  consolidated  international  sales  volumes  and  8%  of 
international  proved  reserves  at  December 31,  2007.  The  concession  covers  12,355  gross  developed  acres  and 
851,771 gross undeveloped acres. 

We have been operating in Ecuador since 1996. We are currently utilizing the natural gas from the Amistad field 
(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. During 2007, power generation totaled 911,830 MW hours. 

Other International—Other international includes China, Argentina and Suriname.  

We have been engaged in exploration and development activities in China since 1996 and production began in 2003. 
We  are  operator  of  the  Cheng  Dao  Xi  field  (57%  working  interest),  which  is  located  in  the  shallow  water  of  the 
southern Bohai Bay. During 2007, activities consisted primarily of workover projects. China accounted for 5% of 
2007  consolidated  international  sales  volumes  and  2%  of  international  proved  reserves  at  December 31,  2007.  At 
December 31, 2007, we held 7,413 gross developed acres and no undeveloped acres. 

We  continue  to  work  with  our  Chinese  partner  (Shengli)  to  obtain  governmental  approval  of  the  Supplemental 
Development  Plan,  designed  to  further  develop  the  Cheng  Dao  Xi  field  through  additional  drilling  and  facilities 
construction.  

Our  producing  properties  in  Argentina  are  located  in  southern  Argentina  in  the  El  Tordillo  field  (13%  working 
interest),  which  is  characterized  by  secondary  recovery  crude  oil  production.  During  2007,  we  participated  in  the 
drilling  of  50  gross  (6.7  net)  development  wells.  Argentina  accounted  for  4%  of  2007  consolidated  international 
sales  volumes  and  2%  of  international  proved  reserves  at  December 31,  2007.  At  December 31,  2007,  we  held 
113,325 gross developed acres and no undeveloped acres in Argentina.  

In December 2007, we entered into an agreement to sell our interest in Argentina for a sales price of $117.5 million, 
effective July 1, 2007. We expect the sale, which is subject to regulatory and partner approvals, to close in 2008. 
Crude oil reserves for the Argentina properties totaled 7 MMBbls at December 31, 2007. 

Suriname, a country located on the northern coast of South America, represents a new exploration area for us. We 
have  entered  into  participation  agreements  on  non-operated  Block  30  (60%  working  interest)  and  on  Block  32 
(100%  working  interest),  which  combined  cover  approximately  7.7 million  gross  acres  offshore.  We  expect  to 
participate in the drilling of one well on the West Tapir prospect on Block 30 in 2008.

 (1)  2007  volumes  include  the  effect  of  crude  oil  sales  less  than  volumes  produced  of  165  MBbls  in  Equatorial 
Guinea, 112 MBbls in the North Sea and 48 MBbls in other international. 2006 volumes include the effect of 
crude oil sales in excess of volumes produced of 195 MBbls in Equatorial Guinea, less than volumes produced 
of  99  MBbls  in  the  North  Sea,  and  in  excess  of  volumes  produced  of  18  MBbls  in  other  international.  The 
variance  between  production  from  the  field  and  sales  volumes  is  attributable  to  the  timing  of  liquid 
hydrocarbon tanker liftings. Sales volumes equal production volumes in 2005. 

(2)  Average natural gas sales prices in the US reflect an increase of $1.12 per Mcf (2007), and reductions of $0.25 
per Mcf (2006) and $0.77 per Mcf (2005) from hedging activities. Average crude oil sales prices for the US 
reflect  reductions  of  $13.68  per  Bbl  (2007),  $11.41  per  Bbl  (2006)  and  $8.03  per  Bbl  (2005)  from  hedging 
activities. Average crude oil sales prices for West Africa reflect reductions of $2.19 (2007) and $9.93 (2005) 
from hedging activities. We did not hedge West Africa crude oil sales in 2006. 

(3)  Average production costs include oil and gas operating costs, workover and repair expense, production and ad 

valorem taxes, and transportation expense. 

(4)  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  facility.  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. For 2007 and 2006, the price on an Mcf basis has been adjusted to reflect the Btu 
content of gas sales. 

(5)  Equatorial Guinea natural gas volumes include sales to the LNG facility of 78,090 Mcfpd for 2007.  There were 

no natural gas sales to the LNG facility before 2007.  

(6)     Other International natural gas volumes include Ecuador and Argentina. Although Ecuador natural gas volumes 
are  included  in  Other  International  production,  they  are  excluded  from  average  natural  gas  sales  prices.  We 
own 100% of the natural gas-to-power project in Ecuador and intercompany natural gas sales are eliminated. 
Natural  gas  production  volumes  associated  with  the  gas-to-power  project  were  9,385  MMcf  for  2007,  8,933 
MMcf for 2006 and 8,321 MMcf for 2005. Other International oil includes China and Argentina. 

(7)  Volumes represent sales of condensate and LPG from the Alba plant in Equatorial Guinea. LPG volumes were 

2,135 MBbls in 2007, 2,297 MBbls in 2006 and 850 MBbls in 2005. 

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

At December 31, 2007, our operated properties accounted for approximately 62% 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—The  number  of  productive  crude  oil  and  natural  gas  wells  in  which  we  held  an  interest  as  of

Productive wells are producing wells and wells 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. A 
net well is deemed to exist when the sum of fractional ownership working interests in gross wells equals one. The 
number of net wells is the sum of the fractional working interests owned in gross wells expressed as whole numbers 
and fractions thereof. One or more completions in the same borehole are counted as one well in this table.

 (1)  The  North  Sea  includes  acreage  in  the  UK,  the  Netherlands  and  Norway.  In  2008,  we  entered  into  an 
agreement,  subject  to  regulatory  approval,  to  sell  our  interest  in  the  Norway  acreage  consisting  of  411,065 
gross (126,607 net) undeveloped acres. 
If production is not established, approximately 731,079 gross acres (433,236 net acres) will expire during 2008, 
424,734 gross acres (193,554 net acres) will expire during 2009, and 683,274 gross acres (367,949 net acres) 
will expire during 2010. 

(2) 

Developed  acreage  includes  leases  that  contain  wells  capable  of  production.  A  gross  acre  is  an  acre  in  which  a 
working interest is owned. A net acre is deemed to exist when the sum of fractional ownership working interests in 
gross acres equals one. The number of net acres is the sum of the fractional working interests owned in gross acres 
expressed as whole numbers and fractions thereof. Undeveloped acreage is considered to be those leased acres on 
which wells have not been drilled or completed to a point that would permit the production of commercial quantities 
of crude oil and natural gas regardless of whether or not such acreage contains proved reserves.

(1)  Does not include wells drilled but not yet completed. 

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

An exploratory well is a well drilled to find and produce crude oil or natural gas in an unproved area, to find a new 
reservoir in a field previously found to be productive of crude oil or natural gas in another reservoir, or to extend a 
known reservoir. A development well, for purposes of the table above and as defined in the rules and regulations of 
the SEC, is a well drilled within the proved area of a crude oil or natural gas reservoir to the depth of a stratigraphic 
horizon known to be productive. 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 the production of crude oil or natural gas, or in the case of a dry hole, to the reporting of 
abandonment to the appropriate agency. 

In addition to the wells drilled and completed during 2007 included in the table above, at December 31, 2007, we 
were  drilling  or  completing  2  gross  (1.0  net)  development  wells  offshore  US,  223  gross  (192.3  net)  development 
wells and 4 gross (3.3 net) exploratory wells onshore US and one gross (0.1 net) development well in Argentina. 

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 also engage 
in  the  purchase  and  sale  of  third-party  crude  oil  and  natural  gas  production.  Such  third-party  production  may  be 
purchased from non-operators who own working interests in our wells or from other producers’ properties in which 
we own no interest. 

Natural  gas  produced  in  the  US  is  sold  predominately  under  short-term  or  long-term  contracts  at  market-based 
prices.  In  Equatorial  Guinea  and  Israel,  we  sell  natural  gas  to  end-users  under  long-term  contracts  at  negotiated 
prices. During 2007, approximately 12% of natural gas sales were made pursuant to long-term contracts. 

Crude oil and condensate produced in the US and foreign locations is 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.  Crude  oil  and  condensate  are distributed  through  pipelines  and  by  trucks or 
tankers to gatherers, transportation companies and refineries.

Significant  Purchaser—Marathon  Petroleum  Supply  Company  (“Marathon”)  was  the  largest  single  non-affiliated 
purchaser of 2007 production and purchased our share of condensate from the Alba field in Equatorial Guinea. Sales 
to Marathon accounted for 18% of 2007 crude oil sales, or 10% of 2007 total oil and gas sales. No other single non-
affiliated purchaser accounted for 10% or more of crude oil and natural gas sales in 2007. 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 remained volatile during 2007 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,  to  achieve  a  more  predictable  cash  flow  by  reducing  our  exposure  to  commodity  price  fluctuations.  For 
additional  information,  see  Item  1A.  Risk  Factors—Hedging  transactions  may  limit  our  potential  gains,  Item 7A. 
Quantitative and Qualitative Disclosures About Market Risk, and Item 8. Financial Statements and Supplementary 
Data—Note 12—Derivative Instruments and Hedging Activities. 

Regulations 

Government  Regulation—Exploration  for,  and  production  and  sale  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, 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. 

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 US Environmental Protection Agency 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 US Environmental Protection Agency, 
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  with  such requirements  will  have  a  material  adverse  effect upon our  capital  expenditures,  earnings or 
competitive position. Although such requirements do have a substantial impact upon 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  and  income  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 and natural gas acquisition, exploration, development 
and  production:  United  States,  West  Africa,  North  Sea,  Israel,  and  Other  International,  Corporate  and  Marketing. 
For more information, see Item 8. Financial Statements and Supplementary Data—Note 15—Segment Information. 

Employees 

Our  total  number  of  employees  increased  during  the  year  from  1,243  at  December 31,  2006  to  1,398  at 
December 31,  2007.  The  2007  year-end  employee  count  includes  181  foreign  nationals  working  as  employees  in 
Ecuador, China, Israel, the UK, Equatorial Guinea, Cameroon and Suriname. 

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, Suriname 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  are  not  so  material  as  to  detract  substantially  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.

Manual. 

Item 1A. Risk Factors. 

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. 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 producing or natural gas 

producing regions; 

•  the level of global crude oil and natural gas inventories; 
•  the price and level of foreign imports; 
•  the price and availability of alternative fuels; 
•  the availability of pipeline capacity and infrastructure; 
•  the availability of crude oil transportation and refining capacity; 
•  weather conditions; 
•  electricity dispatch; 
•  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,  ability  to  finance  planned  capital  expenditures  and  results  of 

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 flow; 
•  reducing the carrying value of our crude oil and natural gas properties; or 
•  limiting our access to sources of capital, such as equity and long-term debt. 

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 
many 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. Our reserve estimates are 
based  on  year-end  commodity  prices;  therefore,  reserve  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; 
•  assumptions concerning future crude oil and natural gas prices; 
•  future operating costs; 
•  severance and excise taxes; 
•  development costs; and 
•  workover and remedial costs. 

17 

 
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,  reserve  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  reserve  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. 

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

Our  acquisition,  exploration,  and  development  activities  require  substantial  capital  expenditures.  Historically,  we 
have  funded  our  capital  expenditures  through  a  combination  of  cash  flows  from  operations,  our  revolving  bank 
credit facility and debt and equity issuances. Future cash flows are subject to a number of variables, such as the level 
of production from existing wells, prices of crude oil and natural gas, and our success in finding, developing and 
producing  new  reserves.  If  revenue  were  to  decrease  as  a  result  of  lower  crude  oil  and  natural  gas  prices  or 
decreased  production,  and  our  access  to  capital  were  limited,  we  would  have  a  reduced  ability  to  replace  our 
reserves, resulting in a decrease in production over time. If our cash flow from operations is not sufficient to meet 
our obligations and fund our capital budget, we may not be able to access debt, equity or other methods of financing 
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. 

A recession or an economic slowdown could have a material adverse impact on our financial position, results of 
operations and cash flows.   

The oil  and gas  industry  is  cyclical  in  nature  and  tends  to  reflect  general  economic  conditions.  Currently,  the US 
economy  is  slowing  and  may  be  headed  toward  a  recession.  A  recession  may  lead  to  significant  fluctuations  in 
demand  and  pricing  for  our  crude  oil  and  natural  gas  production.  If  we  were  to  continue  development  of  our 
property  interests  after  a  decline  in  the  prices  of  crude  oil  and  natural  gas  had  occurred,  our  profitability  may  be 
significantly  affected  by  decreased  demand  and  lower  commodity  prices.  In  addition,  our  future  access  to  capital 
could be limited due to tightening credit markets.   

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

We have significant international crude oil and natural gas operations. These operations may be adversely affected 
by political and economic developments, including the following: 

•  war, terrorist acts and civil disturbances; 
•  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; 
•  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 value of the US dollar; and 
•  other hazards arising out of foreign governmental sovereignty over areas in which we conduct operations. 

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; 

18 

 
•  fires; 
•  explosions, blowouts and cratering; 
•  formations with abnormal pressures; 
•  equipment malfunctions; 
•  hurricanes; 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. 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: 

•  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. 

We  may  be  unable  to  make  attractive  acquisitions  or  integrate  acquired  businesses  and/or  assets,  and  any 
inability to do so may disrupt our business. 

One aspect of our business strategy calls for acquisitions of businesses and assets that complement or expand our 
current business. 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  of  them  or  do  so  on  commercially  acceptable  terms.  Additionally,  if  we  acquire  another  business,  we 
could have difficulty integrating its operations, systems, management and other personnel and technology with our 
own. These difficulties could 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 would be realized. 

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 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,  and  the  Clean  Water  Act.  Environmental  laws  and  regulations  change  frequently  and  the  implementation  of 

19 

 
new, or the modification of existing, laws or regulations 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. 

Potential regulations regarding climate change  could alter the way we conduct our business.  

As awareness of climate change issues increases, governments around the world are beginning to address the issue. 
This may result in new environmental regulations that may unfavorably impact 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.  

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.  As  a  result  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 have increased. 
Additionally, these services may not be available on commercially reasonable terms. 

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. 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  prudent. 
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. 

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.  This 
highly competitive environment could have an adverse impact on our business. 

Our level of indebtedness may limit our financial flexibility. 

As  of  December 31,  2007,  we  had  long-term  indebtedness  of  $1.9 billion  (excluding  unamortized  discount),  with 
$1.2 billion drawn under our bank credit facility. Our indebtedness represented 28% of our total book capitalization 
at December 31, 2007. 

Our level of 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; 

20 

 
•  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; 

•  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  acquisition,  exploration  and  development  activities.  A  higher 
level  of  indebtedness  increases  the risk  that  we  may  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 manage our exposure to price risks in 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 four 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. In trying to manage our exposure to 
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  future  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 any decline in crude oil or natural gas prices. 

Information technology systems implementation issues could disrupt our internal operations, increase our costs 
and adversely affect our financial results or our ability to report our financial results.  

We are currently in the process of implementing a new Enterprise Resource Planning software system to replace our 
various  legacy  systems.  Our  implementation  is  based  on  a  phased  approach,  the  first  phase  of  which  was 
implemented fourth quarter 2007. We expect to implement additional phases during 2008. As a part of this effort, 
we  are  transitioning  data  and  changing  processes  and  this  may  be  more  expensive,  time  consuming  and  resource 
intensive  than  planned.  Any  disruptions  that  may  occur  in  the  implementation  or  operation  of  this  system  or  any 
future  systems  could  increase  our  expenses  and  adversely  affect  our  ability  to  report  in  an  accurate  and  timely 
manner our financial position, results of operations and cash flows and to otherwise operate our business. 

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  stockholders.  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 stockholders. 

Disclosure Regarding Forward-Looking Statements 

This  annual  report  on  Form 10-K  and  the  documents  incorporated  by  reference  in  this  report  contain  forward-
looking statements within the meaning of the federal securities laws. Forward-looking statements give our current 
expectations or forecasts of future events. These forward-looking statements include, among others, the following: 

•  our growth strategies; 
•  our ability to successfully and economically explore for and develop crude oil and natural gas resources; 

21 

 
•  anticipated trends in our business;

Item 3. 

Legal Proceedings. 

We  are  among  a  group  of  eighteen  defendants  named  in  a  lawsuit  filed  August  23,  2002  by  Dore  Energy 
Corporation under Docket Number 10-16202 in the 38th Judicial District Court, Cameron Parish, Louisiana.  The 
lawsuit alleges damage to property owned by Dore resulting from oil and gas activities dating to the 1930’s.  Our 
predecessor, Samedan Oil Corporation, operated on a portion of the property from 1989 to 1999.  Dore has delivered 
documents alleging approximately $140 million in damages. Trial is currently set for April 14, 2008. We intend to 
vigorously defend against these allegations and believe that our share of damages, if any, will not have a material 
adverse effect on our results of operations, financial condition or liquidity. 

The  Illinois  Environmental  Protection  Agency  (“IEPA”)  issued  a  notice  of  violation  to  Equinox  Oil  Company  on 
September 25, 2001 alleging violation of air emission and permitting regulations for a facility known as the Zif Gas 
Plant  located  near  Clay  City,  Illinois.    On  January  17,  2007,  the  IEPA  re-issued  written  notices  of  these  alleged 
violations  in  the  name  of  Equinox’s  successors  in  interest,  and  our  wholly-owned  subsidiaries,  Elysium  Energy, 
LLC  and  Noble  Energy  Production,  Inc.  On  March  16,  2007,  the  IEPA  accepted  our  compliance  commitment 
agreement wherein we agreed to pay a delayed permit fee, install an incineration/caustic scrubber emissions control 
system at the site, and fund a supplemental environmental project (“SEP”) in the nearby community.  At this time, 
we expect no additional monies to be expended other than these amounts for which we have fully accrued.  As of 
December 31, 2007, this matter has been concluded. 

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 consolidated financial position, results of operations or cash flows.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations. 

We  are  an  independent  energy  company  engaged  in  the  acquisition,  exploration,  development,  production  and 
marketing of crude oil and natural gas domestically and internationally. We operate throughout major basins in the 
US including Colorado’s Wattenberg field and Piceance basin, the Mid-continent area of western Oklahoma and the 
Texas Panhandle, the San Juan basin in New Mexico, the Gulf Coast and the deepwater Gulf of Mexico. We also 
conduct business internationally, in China, Ecuador, the Mediterranean Sea, the North Sea, West Africa (Equatorial 
Guinea and Cameroon) and in other areas. 

Our accompanying consolidated financial statements, including the notes thereto, contain detailed information that 
should be referred to in conjunction with the following discussion. 

EXECUTIVE OVERVIEW 

We are a worldwide producer of crude oil and natural gas. Our strategy is to achieve growth in earnings and cash 
flow  through  the  development  of  a  high  quality  portfolio  of  producing  assets  that  is  diversified  between  US  and 
international projects. The Patina Merger, purchase of U.S. Exploration and sale of Gulf of Mexico shelf properties 
have allowed us to achieve a strategic objective of enhancing our US asset portfolio. The result is a company with 
assets  and  capabilities  that  include  growing  US  basins  coupled  with  a  significant  portfolio  of  international 
properties. Our reserve base includes both US and international sources at 58% US and 42% international. We are 
now a larger, more diversified company with greater opportunities for both US and international growth. 

2007  was  a  strong  year  for  us,  both  financially  and  operationally.  Significant  financial  results  included  the 
following: 

•  net income of $944 million, a 39% increase over 2006 net income; 
•  diluted earnings per share of $5.45, a 44% increase over 2006;  
•  cash flow provided by operating activities of $2.0 billion, a 17% increase over 2006; and 
•  completion of  a $500 million common stock repurchase program begun in 2006. 

Significant operational highlights included the following: 

• eight successful exploration wells drilled internationally, six offshore West Africa and two in the North Sea; 
• deepwater Gulf of Mexico exploration success at Isabela (Mississippi Canyon Block 562);  
•  commencement  of  production  and  continued  ramp-up  at  the  Dumbarton  development  and  successful 

exploratory appraisal well drilled at the Flyndre prospect in the UK sector of the North Sea; 

•  completion of the Mari-B #7 well and record natural gas sales in Israel;  
•  continued success of development program in the US Wattenberg field;  and 
• acquisition of approximately 290,000 net acres onshore US in the Piceance basin, Niobrara trend and New 

Albany Shale areas. 

Sale  of  Argentina—In  December  2007,  we  entered  into  an  agreement  to  sell  our  interest  in  Argentina  for  a  sales 
price  of  $117.5  million,  effective  July  1,  2007.  We  expect  the  sale,  which  is  subject  to  regulatory  and  partner 
approvals, to close in 2008.  

Equatorial  Guinea  2006  Hydrocarbons  Law—Effective  November 2006,  the  government  of  Equatorial  Guinea 
enacted  the  2006  Hydrocarbons  Law  governing  petroleum  operations  in  Equatorial  Guinea.  The  governmental 
agency  responsible  for  the  energy  industry  was  given  the  authority  to  renegotiate  any  contract  for  the  purpose  of 
adapting  any  terms  and  conditions  that  are  inconsistent  with  the  new  law.  At  this  time  we  are  uncertain  what 
economic impact this law will have on our operations in Equatorial Guinea. 

2008 OUTLOOK 

We expect crude oil and natural gas production to increase in 2008 compared to 2007. Factors which may impact 
our expected year-over-year increase in production include: 

•  higher sales of natural gas from the Alba field in Equatorial Guinea; and 
•  growing production from the D-J and Piceance basins, where we are continuing active drilling programs;  

offset by: 

•  natural field decline in the Gulf Coast area. 

28 

 
 
Factors which may impact our expected production profile include: 

•  potential hurricane-related volume curtailments in the Gulf of Mexico and Gulf Coast areas; 
•  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; 

•  infrastructure development in Israel; 
•  potential downtime at the methanol, LPG and/or LNG facilities in Equatorial Guinea; 
•  seasonal variations in rainfall in Ecuador that affect our natural gas-to-power project; and 
•  timing of capital expenditures, as discussed below, which are expected to result in near-term production. 

2008 Budget—We have budgeted capital expenditures of approximately $1.6 billion for 2008. Approximately 24% 
of the 2008 capital budget has been allocated to exploration opportunities and 76% has been allocated to production, 
development and other projects. US spending is budgeted for $1.2 billion, international expenditures are budgeted 
for  $392  million  and  corporate  expenditures  are  budgeted  for  $27  million.  The  2008  budget  does  not  include  the 
impact of possible asset purchases. We expect that the 2008 capital budget will be funded primarily from cash flows 
from operations and borrowings under our revolving credit facility. 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. 

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. 

Purchase  Price  Allocation—As  a  result  of  the  Patina  Merger  in  2005  and  the  acquisition  of  U.S.  Exploration  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  reserve  quantities  acquired,  and  estimated  future 
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  merger.  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  basis  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. 

While the estimates of fair value for the assets acquired and liabilities assumed have no effect on our cash flows, 
they can have an effect on the future results of operations. Generally, higher fair values assigned to crude oil and 
natural  gas  properties  result  in  higher  future  depreciation,  depletion  and  amortization  (“DD&A”)  expense,  which 
results in decreased future net earnings. Also, a higher fair value assigned to crude oil and natural gas properties, 
based on higher estimates of future crude oil and natural gas prices, could increase the likelihood of impairment in 

29 

 
the  event  of  lower  commodity  prices  or  higher  operating  or  development  costs  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,  2007,  the  consolidated  balance  sheet  included  $760 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  also  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. 

The impairment assessment requires management to make estimates regarding the fair value of the reporting unit to 
which goodwill has been assigned. The fair value of the US reporting unit was determined using a combination of 
the income approach and the  market approach. Under the income approach, the fair value of the reporting unit is 
estimated  based  on  the  present  value  of  expected  future  cash  flows.  Under  the  market  approach,  the  fair  value  is 
estimated based on selected financial metrics. 

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, 
appropriate  discount  rates  and  other  variables.  Downward  revisions  of  estimated  reserve  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 an impairment of all or a portion of goodwill in future periods. Under the market 
approach,  we  make  certain  judgments  about  the  selection  of  comparable  companies,  comparable  recent  company 
and asset transactions and transaction premiums. Although we have based the fair value estimate on assumptions we 
believe to be reasonable, those assumptions are inherently unpredictable and uncertain and actual results could differ 
from the estimate. In 2007, no goodwill impairment was recognized. 

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.  During  2006,  we  allocated 
$100 million of US reporting unit goodwill to the carrying amount of our Gulf of Mexico shelf properties sold. 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. 

Reserves—All  of  the  reserve  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. 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 
reserve estimate is a function of the quality of available data and of engineering and geological interpretation and 
judgment. As a result, reserve estimates  may be different from the quantities of crude oil and natural gas that are 
ultimately recovered. 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  trigger  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  trigger  a  goodwill 
impairment analysis. 

Oil and Gas Properties—We account for crude oil and natural gas properties under the successful efforts method of 
accounting.  The  alternative  method of  accounting  for  crude oil  and natural  gas properties  is  the  full  cost  method. 
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  proved  reserves  and  to  drill  and  equip  development  wells  are  capitalized. 
Proved property  acquisition  costs  are  amortized  to operations by  the unit-of-production  method on  a property-by-
property 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 
operations by the unit-of-production method on a property-by-property basis. They are amortized based on proved 
developed crude oil and natural gas reserves. Application of the successful efforts method results in the expensing of 

30 

 
certain costs including geological and geophysical costs, exploratory dry holes and delay rentals, during the periods 
the costs are incurred. Under the full cost method, these costs 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 as 
this method is better aligned with our business strategy. 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  will  carry  the  costs  of  an 
exploratory  well  as  an  asset  if  the  well  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 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. 
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, 2007, the balance of property, plant and equipment included $249 million of suspended 
exploratory  well  costs,  $62 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  wells,  or  evaluating  the  potential  of  the  exploration  wells.  For  more  information,  see  Item  8. 
Financial Statements and Supplementary Data—Note 5—Capitalized Exploratory Well Costs. 

Impairment of Proved Oil and Gas Properties—We assess proved crude oil and natural gas properties for possible 
impairment  when  events  or  circumstances  indicate  that  the  recorded  carrying  value  of  the  properties  may  not  be 
recoverable. We recognize an impairment loss as a result of a triggering event and when the estimated undiscounted 
future  cash  flows  from  a  property  are  less  than  the  carrying  value.  If  impairment  is  indicated,  the  cash  flows  are 
discounted  at  a  rate  approximate  to  our  cost  of  capital  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  and  operating 
costs. Downward revisions in estimates of reserve quantities or expectations of falling commodity prices or rising 
operating costs could result in a reduction in undiscounted future cash flows and could indicate property impairment. 
We recorded approximately $4 million of impairments in 2007, primarily related to adjustment of the carrying value 
of properties to their fair values. 

Impairment of Unproved Oil and Gas Properties—We also perform periodic assessments of individually significant 
unproved  crude  oil  and  natural  gas  properties  for  impairment.  Cash  flows  used  in  the  impairment  analysis  are 
determined based upon management’s estimates of natural gas and crude oil reserves, future commodity prices and 
future  costs  to  extract  the  reserves. Downward  revisions  in  estimated  reserve 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 amounts 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 at a rate approximate to 
our cost of capital 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 price curves 
for  the  related  commodities,  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. During 2007, we 
recorded impairments of significant unproved oil and gas properties totaling approximately $3 million in exploration 
expense.

Asset  Retirement  Obligation—Our  asset  retirement  obligations  (“ARO”)  consist  of  estimated  costs  of 
dismantlement,  removal,  site  reclamation  and  similar  activities  associated  with  our  oil  and  gas  properties. 
Statement of Financial Accounting Standards (“SFAS”) No. 143, “Accounting for Asset Retirement Obligations,” 
requires that the discounted 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 must 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. 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.  See  Item  8.  Financial 
Statements and Supplementary Data—Note 6—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 
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 and Katrina.  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  during  2007.    See  Item  8. 
Financial Statements and Supplementary Data—Note 4—Effect of Gulf Coast Hurricanes. 

Derivative Instruments and Hedging Activities—We use various derivative instruments to minimize  the impact of 
commodity  price  fluctuations  on  forecasted  sales  of  crude  oil  and  natural  gas  production.  We  also  use  derivative 
instruments in connection with purchases and sales of third-party production to lock in profits or limit exposure to 
commodity price risk. 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. We account for 
derivative  instruments  under  SFAS  No. 133,  “Accounting  for  Derivative  Instruments  and  Hedging  Activities,  as 
amended”. For derivative instruments that qualify as cash flow hedges, changes in fair value, to the extent the hedge 
is  effective,  are  recognized  in  accumulated  other  comprehensive  income  or  loss  (“AOCL”)  until  the  hedged 
forecasted transaction is recognized in earnings. Therefore, prior to settlement of the derivative instruments, changes 
in the fair market value of those derivative instruments can cause significant increases or decreases in AOCL. For 
derivative instruments that do not qualify as cash flow hedges, changes in fair value are reported in current period 
net  income  and  therefore  can  result  in  significant  increases  or  decreases  in  current  period  net  income.  All  hedge 
ineffectiveness  is  recognized  in  the  current  period  in  net  income.  Ineffectiveness  is  the  amount  of gains  or  losses 
from  derivative  instruments  which  are  not  offset  by  corresponding  and  opposite  gains  or  losses  on  the  expected 
future  transaction.  Regression  analysis  is  performed  on  initial  assessment  of  the  hedge  and  subsequently  every 
quarter thereafter in order to determine that the hedge instrument will be or has been highly effective in offsetting 

32 

 
gains or losses on the future transaction. As discussed in Item 8. Financial Statements and Supplementary Data—Note 
2—Summary of Significant Accounting Policies, we voluntarily discontinued cash flow hedge accounting for our commodity 
derivative instruments, effective January 1, 2008. Such a change did not affect our net assets or cash flows at December 
31, 2007 and will not require adjustments to our previously reported financial statements. However, the use of mark-
to-market accounting for our commodity derivatives will likely add volatility to our reported earnings.  

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. See Item 8. Financial Statements and Supplementary Data—Note 
12—Derivatives and Hedging Activities.   

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. 

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. Over the last three years, we have increased the 
allowance  by  approximately  $40 million  to  cover  potentially  uncollectible  balances  related  to  the  Ecuador  power 
operations.  Certain  entities  purchasing  electricity  in  Ecuador  have  been  slow  to  pay  amounts  due  us.  We  are 
pursuing  various  strategies  to  protect  our  interests  including  international  arbitration  and  litigation.  However,  if 
estimates are inaccurate, we may incur gains or losses that could have a material effect on our results of operations. 

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 

33 

 
future value of assets will be impacted as previously deferred gains or losses are recorded. As of January 1, 2007, 
cumulative  asset  gains  of  approximately  $3 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  2007  net 
periodic benefit cost by approximately $1 million. The expected return assumption used for 2007 was 8.25%. 

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, 2007 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 2007 net periodic benefit 
cost  by  $4 million  and  decreased  the  benefit  obligation  for  the  combined  plans  by  $17 million  at  December 31, 
2007.  A  1%  decrease  in  the  discount  rate  assumption  would  have  increased  2007  net  periodic  benefit  cost  by 
$5 million and increased the benefit obligation for the combined plans by $20 million at December 31, 2007. The 
assumed discount rate used to determine net periodic benefit cost for 2007 was 5.75%. The assumed discount rate 
used  to  determine  the  benefit  obligations  at  December 31,  2007  was  6.5%  for  our  defined  benefit  pension  and 
restoration plans and 6.25% for our medical and life plans. 

Effective January 1, 2008, the defined benefit pension plan and restoration plans were amended in order to provide a 
lump sum option. Certain assumptions were made regarding the percentage of active participants who would elect 
the lump sum option upon future termination and the percentage of existing deferred vested participants who would 
elect the lump sum option during 2008. In addition, the amounts of lump sum payments are affected by mortality 
and  interest  rate  assumptions.  The  lump  sum  option  increased  the  projected  benefit  obligation  by  $5.5  million  at 
December 31, 2007 and will increase 2008 net periodic benefit cost by approximately $1 million. 

We adopted SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, 
an amendment of FASB Statements No. 87, 88, 106 and 132(R), as of December 31, 2006. See Item 8. Financial 
Statements and Supplementary Data—Note 11—Benefit Plans.

LIQUIDITY AND CAPITAL RESOURCES 

Overview 

Our primary cash needs are to fund capital expenditures related to the acquisition, exploration and development of 
crude oil and natural gas properties, to repay outstanding borrowings or to pay other contractual commitments and 
interest  payments  on debt  and  to  pay  dividends.  Our  traditional  sources  of  liquidity  are  cash  on hand,  cash  flows 
from  operations  and  available  borrowing  capacity  under  credit  facilities.  Funds  may  also  be  generated  from 
occasional sales of non-strategic crude oil and natural gas assets. We had $660 million in cash and cash equivalents 
at December 31, 2007, compared with $153 million at December 31, 2006. Substantially all of this cash is located in 
our foreign subsidiaries and would be subject to additional US income taxes if repatriated. The cash is denominated 
in US dollars and is invested in highly liquid, investment-grade securities with original maturities of three months or 
less  at  the  time  of  purchase.  We  currently  intend  to  use  our  international  cash  to  fund  international  projects, 
including the development of West Africa. 

We are monitoring the current conditions in the credit markets. We have reviewed 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  affected.  We  believe  that  losses  from 
nonperformance are unlikely to occur; however, we are not able to predict sudden changes in creditworthiness.  

34 

 
Our ratio of debt-to-book capital has decreased from 30% at December 31, 2006, to 28% at December 31, 2007. 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. Significant changes 
in our financial position causing a change in the ratio of debt-to-book capital include: 

•  a $75 million increase in total debt from the balance at December 31, 2006; 
•  a $944 million increase in shareholders’ equity from current year net income; 
•  a $102 million decrease in shareholders’ equity due to repurchase of common stock; and 
•  a  $144 million  decrease  in  shareholders’  equity  (effected  by  an  increase  in  AOCL) primarily  related  to  an 

increase in deferred hedging losses.

Operating  Activities—Net  cash  provided  by  operating  activities  increased  $286  million,  or  17%  during  2007  as 
compared with 2006. The increase was due primarily to higher average realized crude oil prices and higher average 
realized US natural gas prices. These increases were partially offset by higher exploration expense and general and 
administrative (“G&A”) expense. In addition, cash flows from operating activities in 2007 included dividends from 
equity method investments, which had been classified as investing cash flows in 2006. See Results of Operations—
Income from Equity Method Investees. 

Net cash provided by operating activities increased $490 million, or 40%, during 2006 as compared with 2005. The 
increase  was  due  primarily  to  higher  sales  volumes  and  higher  average  realized  crude  oil  prices,  offset  by  lower 
average realized US natural gas prices and increases in total production costs, G&A expense and interest expense. 

Investing Activities—The primary use of cash in investing activities is for capital spending, which may be offset by 
proceeds  from  property  sales  or  dividends  from  equity  method  investees.  Net  cash  used  in  investing  activities 
increased $305 million, or 28% during 2007 as compared with 2006. The change was due primarily to a decrease in 
divestiture activity in 2007 as compared with 2006, when we sold our Gulf of Mexico shelf properties. In addition, 
investing  cash  inflows  were  reduced  in  2007  because  distributions  received  from  equity  method  investees  were 
included in operating cash flows. See Results of Operations—Income from Equity Method Investees. 

Net  cash  used  in  investing  activities  decreased  $794  million,  or  42%  during  2006  as  compared  with  2005.  The 
decrease was due primarily to a decrease in acquisition activity in 2006 as compared to the Patina Merger in 2005 
and an increase in divestiture activity in 2006, due to the sale of our Gulf of Mexico shelf properties, which provided 
investing cash inflows in 2006.

Financing Activities—Net cash used in financing activities decreased $482 million during 2007 as compared with 
2006. The change was due to net increases in the credit facility during 2007 as compared with payments being made 
to decrease outstanding debt during 2006. In 2007 there was also a net decrease of $297 million in amounts used to 
repurchase  common  stock  as  compared  with  2006.  Cash  flows  were  provided  by  financing  activities  in  2005,  as 
compared with 2006, and totaled $583 million. In 2005, cash was provided by borrowings under the credit facility 
and exercise of stock options, partially offset by dividend payments and the repayment of debt acquired in the Patina 
Merger.

Total capital expenditures during 2007 increased $392 million, or 29%, as compared with 2006. The increase was 
due  to  lease  acquisition  in  the  US,  exploratory  activities  in  West  Africa  and  the  North  Sea,  and  increased 
development  activity  in  the  Northern  region  and  Gulf  of  Mexico  area  of  our  US  operations.  Total  capital 
expenditures during 2006 increased $457 million, or 51%, as compared with 2005. The increase was primarily due 
to development expenditures in the US and the North Sea. Capital expenditures for 2005 included $275 million of 
post-merger exploration and development-related expenditures on Patina properties.  

As  a  result  of the  U.S.  Exploration  acquisition  in  2006, we  allocated  $413  million  to proved properties  and $131 
million  to  unproved  properties.  As  a  result  of  the  Patina  Merger  in  2005,  we  allocated  $2.6  billion  to  proved 
properties and $1.1 billion to unproved properties.

Our corporate insurance program provides up to $260 million property damage coverage per loss event. However, 
our  insurance  carrier’s  aggregation  limit  for  catastrophic  windstorm  events  is  $750  million.  If  an  insured 
catastrophic  loss  event  occurs,  we  could  still  recover  less  than  our  stated  limits  should  the  total  aggregate  losses 
realized by our carrier exceed its $750 million aggregation limit applicable to any single loss event. 

We carry additional property damage and control of well coverage for our deepwater Gulf of Mexico and remaining 
Gulf  of  Mexico  shelf  properties.  This  additional  insurance  provides  coverage  only  for  claims  in  excess  of  $100 
million,  which  exceed  the  $260  million  property  damage  coverage  or  where  the  $260  million  property  damage 
coverage is reduced by application of the $750 million aggregation limit. We carry business interruption insurance 
for certain international locations. Effective June 2007, we no longer carry business interruption insurance for our 
Gulf of Mexico operations. 

Financing Activities 

Long-Term Debt—Our long-term debt totaled $1.9 billion (excluding unamortized discount) at December 31, 2007. 
Maturities range from 2009 to 2097. Our principal source of liquidity is an unsecured revolving credit facility (the 
“Credit Facility”). In November 2007, we extended the Credit Facility until 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. 

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.  At  December 31,  2007,  the  total 
debt to capitalization ratio was 28%, calculated for this purpose as total debt divided by the sum of total debt plus 
shareholders’ equity. 

The Credit Facility is with certain commercial lending institutions and is available for general corporate purposes. 
At December 31, 2007, $1.2 billion in borrowings were outstanding under the Credit Facility. The weighted average 
interest rate applicable to borrowings under the Credit Facility at December 31, 2007 was 5.28%. 

We also have $650 million of fixed-rate debt outstanding at December 31, 2007 with a weighted average interest 
rate of 6.92%. Maturities range from 2014 to 2097.  

Installment Payments Due—During 2007, we purchased working interests in oil and gas properties in the Piceance 
basin of western Colorado for $75 million. After making an initial cash payment of $25 million, we owe $50 million 
in the form of installment payments to the seller. Installments of $25 million each are due on May 12, 2008 and May 
11, 2009.  The amount due in 2008 is included in short-term borrowings and the amount due in 2009 is included in 
long-term debt in the consolidated balance sheets. Interest on the unpaid amounts is due quarterly. Interest accrues at 
a LIBOR rate plus .30%.  The interest rate was 5.53% at December 31, 2007. 

Short-Term Borrowings—Our Credit Facility 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, there were 
no short-term borrowings outstanding at December 31, 2007. 

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 which are scheduled to expire third 
quarter 2008. See Item 8. Financial Statements and Supplementary Data—Note 7—Debt. 

Cash  Interest  Payments—We  made  cash  interest  payments,  net  of  capitalized  interest,  of  $105 million  in  2007, 
$106 million in 2006 and $84 million in 2005. 

Common Stock Repurchase Program—During 2007 we completed a common stock repurchase program authorized 
by our Board of Directors in 2006. We repurchased two million shares of our common stock at an aggregate cost of 
$101  million  in  2007  and  8.4 million  shares  of  our  common  stock  at  an  aggregate  cost  of  $399 million  in  2006, 
resulting in a total of 10.4 million shares acquired at an average price of $48.17 per share. 

Dividends—We paid cash dividends totaling 43.5 cents per common share in 2007, 27.5 cents per common share in 
2006 and 15 cents per common share in 2005. On January 22, 2008, the Board of Directors declared a quarterly cash 
dividend  of  12.0  cents  per  common  share,  which  was  paid  February 19,  2008  to  shareholders  of  record  on 
February 4, 2008. 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. 

Exercise of Stock Options—Proceeds from the exercise of stock options totaled $25 million in 2007, $63 million in 
2006 and $68 million in 2005. 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.

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,  2007,  the  material  off-balance  sheet  arrangements  and  transactions  that  we  have 
entered into included drilling service contracts, operating lease agreements, undrawn letters of credit and derivative 
contracts.  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.

(1)  Based on the total debt balance outstanding at December 31, 2007, scheduled maturities and interest rates in 
effect at December 31, 2007, our cash payments for interest would be $109 million in 2008, $108 million in 
2009, $107  million  in 2010, $107 million  in  2011, $107 million  in 2012  and $990  million  for  the  remaining 
years for a total of $1.5 billion. See Item 8. Financial Statements and Supplementary Data—Note 7—Debt for 
additional information regarding our long-term debt obligations. 

(2)  Drilling  and  equipment  obligations  represent  contractual  agreements  with  third  party  service  providers  to 
procure drilling rigs and other related equipment for developmental and exploratory drilling facilities.  See Item 
8.  Financial  Statements  and  Supplementary  Data—Note  14—Commitments  and  Contingencies  for  additional 
information regarding our drilling and equipment obligations. 

 (3)  Purchase  obligations  represent  agreements  to  purchase  goods  or  services  that  are  enforceable,  are  legally 
binding  and  specify  all  significant  terms,  including  fixed  and  minimum  quantities  to  be  purchased;  fixed, 
minimum  or  variable  price  provisions;  and  the  approximate  timing  of  the  transaction.  See  Item  8.  Financial 
Statements  and  Supplementary  Data—Note  14—Commitments  and  Contingencies  for  additional  information 
regarding our purchase obligations. 
In January 2007, we entered into a five-year throughput agreement. The transporting pipeline is expected to be 
completed  and  operational  in  2009.    See  Item  8.  Financial  Statements  and  Supplementary  Data—Note  14—
Commitments and Contingencies for additional information regarding our throughput agreement.

(5)  Operating lease obligations represent non-cancelable leases for office buildings and facilities and oil and gas 
operations equipment used in our daily operations. See Item 8. Financial Statements and Supplementary Data 
—Note  14—Commitments  and  Contingencies  for  additional  information  regarding  our  operating  lease 
obligations. 

(6)  The table does not include our deferred compensation liabilities of $225 million and our accrued benefit costs 
of $51  million  as  specific  payment  dates  are  unknown. See  Item  8.  Financial  Statements  and  Supplementary 
Data—Note  11—Benefit  Plans  for  additional  information  on  our  deferred  compensation  liability  and  our 
accrued benefit costs. 

(7)  Asset retirement obligations are discounted. See Item 8. Financial Statements and Supplementary Data—Note 

6—Asset Retirement Obligations for additional information on our asset retirement obligations. 

(8)  See  Item  8.  Financial  Statements  and  Supplementary  Data—Note  12—Derivative  Instruments  and  Hedging 

Activities for additional information on our derivative instrument obligations. 

We  accrued  approximately  $12 million  as  of  December 31,  2007,  for  an  insurance  contingency  due  to  our 
membership in Oil Insurance Limited (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 $1 million at December 31, 2007. 

Other 

Contributions  to  Pension  and  Other  Postretirement  Benefit  Plans—We  made  contributions  to  the  pension, 
restoration  and  other  postretirement  benefit  plans  totaling  $12 million  during  2007,  $36 million  during  2006,  and 
$14 million during 2005. The actual return on plan assets was $13 million in both 2007 and 2006. 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  pension  plans  become  fully  funded  over  a  seven-year  period 
beginning  in  2008.  As  a  result  of  previous  contributions  made  to  the  pension  plan,  there  are  no  required 
contributions  expected  during  2008.  We  may,  however,  make  additional  contributions  to  our  pension  plan.  We 
expect  to  make  contributions  of  $4 million  to  the  unfunded  restoration  and  medical  and  life  plans  in  2008.  This 
amount is equal to the benefits expected to be paid by those plans. 

Income Taxes—We made cash payments for income taxes, net of refunds, of $149 million during 2007, $115 million 
during 2006 and $122 million during 2005. 

Contingencies—During  2007,  we  paid  a  total  of  $56  million  to  settle  legal  proceedings;  these  amounts  had  been 
accrued previously. During 2006 and 2005, no significant payments were made to settle any legal proceedings. 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. 

RESULTS OF OPERATIONS 

Net Income 

Net income for 2007 was $944 million, a 39% increase over 2006. Factors contributing to the increase in net income 
from 2006 to 2007 included: 

•  a $332 million, or 11%, increase in total revenues, due primarily to higher average realized crude oil prices 
and higher average realized US natural gas prices and an increase in income from equity method investees; 

• a  $395 million decrease in loss on derivative instruments; and  

offset by: 

•  a $208 million decrease in gains from asset sales;  
•  a $105 million increase in DD&A expense;  
•  a $51 million loss on involuntary conversion expense; and  
•  a $51 million increase in oil and gas exploration expense. 

39 

 
Net income for 2006 was $678 million, a 5% increase over 2005. Factors contributing to the increase in net income 
from 2005 to 2006 included: 

•  a $753 million, or 34%, increase in total revenues, driven primarily by a full year of Patina operations and 

nine months of U.S. Exploration operations and higher average realized oil prices; 

•  an increase of $215 million in gains from asset sales;  

offset by: 

•  an increase in loss on derivative instruments of $360 million; and 
•  a $232 million increase in DD&A expense.

(1)  Reflects an increase of $1.12 per Mcf in 2007 and reductions of $0.25 per Mcf in 2006 and $0.77 per Mcf in 

2005 from hedging activities.  

(2)  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  facility.  The  methanol  and  LPG  plants  are  owned  by  affiliated  entities 
accounted for under the equity method of accounting. The volumes sold by the LPG plant are included in the 
table below under crude oil information. Natural gas volumes include sales to an LNG facility of 78,090 Mcfpd 
2007; there were no natural gas sales to the LNG facility before 2007. The natural gas sold to the LNG facility 
and methanol plant has a lower Btu content than the natural gas sold to the LPG plant. As a result of the natural 
gas volumes sold to the LNG plant in 2007, the average price received on an Mcf basis is lower. For 2007 and 
2006, the price on an Mcf basis has been adjusted to reflect the Btu content on gas sales. 

(3)  The  natural  gas-to-power  project  in  Ecuador  is  100%  owned  by  one  of  our  subsidiaries,  and  intercompany 
natural gas sales are eliminated for accounting purposes. Electricity sales included in total revenues totaled $71 
million in 2007, $72 million in 2006 and $74 million in 2005. 

2007 Compared with 2006—Natural gas sales increased a net $60 million, or 5%, during 2007 as compared with 
2006.  The  increase  was  affected  by  both  volume  and  price  changes.  In  the  US,  natural  gas  sales  increased  $40 
million  from  the  previous  year  despite  lower  sales  volumes.  Deepwater  Gulf  of  Mexico  volumes  were  slightly 
higher  than  2006,  while  development  activity  in  the  Piceance  basin  and  a  full  year  of  production  from  U.S. 
Exploration properties acquired in 2006 resulted in increased production in the Northern region. However, the Gulf 
Coast onshore area had lower production due to natural field decline, and there was a loss of production due to the 
sale of our Gulf of Mexico shelf properties in 2006. The Northern region also experienced a temporary decline in 
production due to third party processing downtime and inclement weather. The net production decrease was more 
than offset by a 14% increase in average realized natural gas prices.

Internationally, West Africa natural gas sales increased $8 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  the  North  Sea,  natural  gas  production 
decreased 23% as compared with the prior year primarily due to natural field decline. Lower production, combined 
with lower average realized prices, resulted in a $9 million decrease in North Sea natural gas sales. In Israel, natural 
gas  sales  increased  $21  million  due  to  record  sales  volumes.  There  was  a  full  year  of  sales  to  Israeli  Electric 
Company’s Reading power plant in Tel Aviv, as well as the start up of sales to a desalinization plant and a paper 
mill. 

2006 Compared with 2005—Natural gas sales increased a net $188 million, or 18%, during 2006 as compared with 
2005.  Again,  the  change  was  caused  by  both  significant  volume  and  price  changes.  In  the  US  natural  gas  sales 
increased by $157 million from the previous year due to additional US production from Patina properties acquired in 
2005  and  from  U.S.  Exploration  properties  acquired  in  May  2006.  In  addition,  there  were  increases  in  deepwater 
Gulf of Mexico production where three new developments came on stream at Swordfish, Ticonderoga and Lorien. 
However, increases due to higher gas sales volumes were partially offset by lower average realized prices. 

Internationally, West Africa natural gas sales were flat year-to-year; however, there was a decline in sales volumes 
due to the turnaround of the AMPCO methanol plant in Equatorial Guinea. The turnaround lasted 57 days and was 
followed  by  reduced  production  levels  caused  by  35  days  of  compressor  repairs.  The  production  decline  was 
completely  offset  by  an  increase  in  average  realized  natural  gas  prices.  In  the  North  Sea,  natural  field  decline 
resulted in reduced sales volumes, but this reduction was more than offset by the increase in average realized prices. 
Israel experienced a $4 million increase in natural gas sales primarily due to increased demand from Israel Electric 
Corporation  Limited,  a  full  year  of  sales  to  Bazan  Oil  Refinery  and  commencement  of  natural  gas  sales  to  the 
Reading power plant in Tel Aviv, Israel.  

Natural Gas Hedging Activities—Natural gas sales are net of the effects of derivative contracts that are accounted 
for as cash flow hedges and included an increase of $169 million in 2007, and a reduction of $42 million in 2006 
and $97 million in 2005 from hedging activities.  Natural gas sales in 2007 include a $182 million non-cash increase 
related to hedge contracts that were redesignated at the time of the Gulf of Mexico shelf property sale in 2006 and 
settled during 2007. See Item 8. Financial Statements and Supplementary Data—Note 12—Derivative Instruments 
and Hedging Activities.

(1)   The variance between production and sales volumes is attributable to the timing of liquid hydrocarbon tanker 

liftings. 

(2)  Sales volumes equal production volumes in 2005.  
(3)  Reflects reductions of $13.68 per Bbl in 2007, $11.41 per Bbl in 2006 and $8.03 per Bbl in 2005 from hedging 

activities. 

(4)  Reflects reductions of $2.19 per Bbl in 2007 and $9.93 per Bbl in 2005 from hedging activities. We did not 

hedge West Africa crude oil sales in 2006. 

(5)  Other international includes China and Argentina.  
(6)  Volumes represent sales of condensate and LPG from the Alba plant in Equatorial Guinea. LPG sales volumes 

totaled 5,848 Bopd in 2007, 6,294 Bopd in 2006 and 2,328 Bopd in 2005. 

2007 Compared with 2006—Crude oil sales increased a net $205 million, or 14%, during 2007 as compared with 
2006.  The  increase  was  affected  by  both  volume  and  price  changes.  In  the  US,  crude  oil  sales  declined  by  $25 
million from the previous year. Deepwater Gulf of Mexico volumes were lower due to well performance, third-party 
facility restrictions and storm shut-in. The Gulf Coast onshore area had lower production due to natural field decline, 
and there was a loss of production due to the sale of our Gulf of Mexico shelf properties in 2006. Northern region 
production was negatively impacted by severe winter weather in the Rocky Mountains during the first and fourth 
quarters of 2007. However, development activity in the Wattenberg field, as well as a full year of production from 
U.S.  Exploration  properties  acquired  in  2006,  resulted  in  increased  production  in  our  Northern  region,  and  the 
overall US volume decline was partially offset by higher average realized prices. 

Internationally, West Africa crude oil sales declined by $15 million from the previous year. Volumes declined due to 
increased downtime and lower condensate yields in Equatorial Guinea, but the decline was offset by substantially 
higher average realized crude oil prices. In January 2007, production began at the Dumbarton development in the 
North Sea, and, as a result, crude oil production was more than triple that of the prior year. North Sea crude oil sales 
increased  $257  million  over  2006  due  to  the  increased  volumes  and,  to  a  lesser  extent,  higher  average  realized 
prices.  Other  international  crude  oil  sales  declined  $12  million.  China  experienced  lower  volumes  due  to  facility 
downtime and natural field decline.  

2006 Compared with 2005—Crude oil sales increased a net $547 million, or 58%, during 2006 as compared with 
2005. Again, the increase was caused by significant volume and price changes. In the US crude oil sales increased 
by $405 million from the previous year due to additional US production from Patina properties acquired in 2005 and 
from  U.S.  Exploration  properties  acquired  in  May  2006.  In  addition,  there  were  increases  in  deepwater  Gulf  of 
Mexico production where three new developments came on stream at Swordfish, Ticonderoga and Lorien. 

Internationally, higher average realized prices resulted in an increase of $132 million in West Africa crude oil sales 
and contributed to most of the $22 million increase in other international crude oil sales. The North Sea experienced 
a $12 million decrease in crude oil sales. Natural field decline and timing of tanker liftings resulted in lower sales 
volumes, the effect of which was mitigated by an increase in average realized crude oil prices. 

Crude Oil Hedging Activities—Crude oil sales are net of the effects of derivative contracts that are accounted for as 
cash flow hedges and included a reduction of $223 million in 2007, $191 million in 2006 and $140 million in 2005 
from  hedging  activities.    See  Item  8.  Financial  Statements  and  Supplementary  Data—Note  12—Derivative 
Instruments and Hedging Activities. 

Commodity Derivative Instruments and Hedging Activities 

We use various derivative instruments in connection with anticipated crude oil and natural gas sales to minimize the 
impact  of  product  price  fluctuations.  Such  instruments  include  variable  to  fixed  price  swaps,  costless  collars  and 
basis  swaps.  Although  these  derivative  instruments  expose  us  to  credit  risk,  we  monitor  the  creditworthiness  of 
counterparties and believe that losses from nonperformance are unlikely to occur. Hedging gains and losses related 
to crude oil and natural gas production are recorded in oil and gas sales. See Item 7A. Quantitative and Qualitative 
Disclosures  About  Market  Risk—Commodity  Price  Risk  and  Item  8.  Financial  Statements  and  Supplementary 
Data—Note 12—Derivative Instruments and Hedging Activities.

(1)   The variance between production and sales volumes is attributable to the timing of liquid hydrocarbon tanker 

liftings. 

Net income from AMPCO and affiliates increased substantially in 2007 relative to 2006 due to a 46% increase in 
methanol  sales  volumes  and  a  21%  increase  in  average  realized  methanol  prices.  The  increase  in  methanol  sales 
volumes was due to a 57-day shutdown of methanol production for the plant turnaround that occurred during May 
and June 2006 followed by 35 days of compressor repairs. 

Net income from AMPCO and affiliates decreased 33% in 2006 relative to 2005 due to a 32% decrease in methanol 
sales volumes offset by a 17% increase in average realized methanol prices. The decrease in methanol sales volumes 
was due to the 57-day shutdown of methanol production for the plant turnaround that occurred during May and June 
2006 followed by 35 days of compressor repairs. No such shutdown or plant turnaround occurred during 2005. 

Net income from Alba Plant increased 26% in 2007 relative to 2006 due to a 22% increase in average realized LPG 
prices and a 12% increase in average realized condensate prices.  

Net income from Alba Plant increased substantially in 2006 relative to 2005 due to an almost threefold increase in 
LPG sales volumes, an almost twofold increase in condensate sales volumes and a 19% increase in average realized 
condensate prices. The increases in LPG and condensate sales volumes reflected the completion and ramp up to full 
production of the Phase 2B liquids expansion project. 

For  2007,  $132  million  received  from  Alba  Plant  was  classified  within  operating  cash  flows  as  a  dividend  from 
equity method investee as compared with 2006 in which the distributions were classified within investing cash flows 
as a repayment of a loan. The change in classification was the result of all outstanding loans being repaid to us by 
Alba Plant in December 2006.

(1)  Oil and gas operating costs include labor, fuel, repairs, replacements, saltwater disposal and other related lifting 

costs.  

(2)  Other international includes Ecuador, China and Argentina. 

Oil and gas operating costs increased $29 million, or 11%, from 2006 to 2007. The increase is primarily the result of 
expanded operations in Equatorial Guinea and the North Sea.  

Oil and gas operating costs increased $66 million, or 33%, from 2005 to 2006 primarily as a result of our expanded 
operations. Three new deepwater Gulf of Mexico development projects came online between December 2005 and 
April 2006. Fiscal year 2006 represented a full year of Patina operations, and we acquired U.S. Exploration in 2006. 
In  addition,  the  high  commodity  price  environment  resulted  in  higher  service,  contract  labor  and  fuel  costs. 
Insurance costs were also higher in 2006 due in part to increased rates for property damage coverage combined with 
the added costs of providing business interruption coverage on deepwater Gulf of Mexico assets. 

Workover  and  repair  expense  decreased  $24  million  during  2007  as  compared  with  2006.  The  decrease  was 
primarily due to a reduction in hurricane-related repair expense, which totaled $30 million in 2006 and $1 million in 
2007.  

Workover and repair expense increased $33 million during 2006 as compared with 2005. Expense for 2006 included 
$30 million ($0.45 per BOE) of hurricane-related repair expense.

Production  and  ad  valorem  tax  expense  increased  $5  million,  or  4%,  during  2007  as  compared  with  2006  and 
increased $30 million, or 38%, during 2006 as compared with 2005. The increase reflects additional production from 
U.S. Exploration and Patina properties. These properties have proportionately more production subject to such taxes. 

Transportation expense increased $23 million, or 81%, during 2007 as compared with 2006. The increase was due 
primarily  due  to  changes  in  the  terms  of  certain  sales  contracts  for  Northern  region  production  and  increased 
production in the North Sea. Transportation expense increased $12 million, or 70%, during 2006 as compared with 
2005. The increase was primarily due to a full year of Patina operations and U.S. Exploration. 

Selected expenses on a per BOE of sales volume basis were as follows:

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

(2) Sales volumes include natural gas sales to an LNG facility in Equatorial Guinea that began late first quarter of 

2007. The inclusion of these volumes reduced the unit rate by $0.51 per BOE for 2007. 

The unit rates of total production costs per BOE, converting gas to oil on the basis of six Mcf per barrel, have been 
increasing  year-over-year  since  2005.  The  increases  are  due  to  rising  third-party  costs,  including  insurance, 
hurricane-related repair expense, and higher production taxes.

Exploration  expense  increased  $51  million,  or  30%  during  2007  as  compared  with  2006.  US  dry  hole  expense 
decreased $17 million due to a reduction in the number of dry holes drilled during 2007. Dry hole expense increased 
$40 million in West Africa and included amounts related to a dry exploratory well in Equatorial Guinea and expense 
related to a secondary target of an exploration well in Cameroon in which commercial hydrocarbons were not found. 
Seismic expense increased a net $27 million during 2007 as compared with 2006, primarily due to increases in US 
seismic expense incurred in support of the 2007 Central Gulf of Mexico Outer Continental Shelf Sale. Staff expense 
increased a net $6 million primarily due to new venture activity. 

Exploration expense decreased $11 million, or 6% during 2006 as compared with 2005. US dry hole expense was 
$30 million less due to the reduction in the number of dry holes drilled. US seismic expense increased $18 million 
due  primarily  to  the  expansion  of  our  deepwater  Gulf  of  Mexico  3D  seismic  database.  In  addition,  other 
international staff expense increased $6 million due to new venture activity. 

Exploration expense included stock-based compensation expense of $2 million in 2007 and $1 million in 2006.

(1) Consolidated unit rates exclude sales volumes and costs attributable to equity method investees.  
(2) Sales volumes include natural gas sales to an LNG facility in Equatorial Guinea that began late first quarter of 

2007. The inclusion of these volumes reduced the unit rate by $0.62 per BOE for 2007. 

Total DD&A expense has been increasing since 2005 primarily due to higher production volumes. The increase in 
the unit rate for 2007 as compared with 2006 was primarily due to higher acquisition and development costs in the 
the US and the Dumbarton North Sea development. The increase in the unit rate for 2006 as compared with 2005 
was  primarily  due  to  the  change  in  the  mix  of  our  production  volumes,  in  particular,  deepwater  Gulf  of  Mexico 
production. 

DD&A expense includes abandoned assets cost of $5 million in 2007, $1 million in 2006 and $11 million in 2005.

2007. The inclusion of these volumes reduced the unit rate by $0.21 per BOE for 2007. 

G&A expense increased $42 million, or 25%, during 2007 as compared with 2006 due to higher salaries and wages, 
including  incentive  compensation  programs,  resulting  from  an  increase  in  the  number  of  employees  and  results 
exceeding  targeted  performance  goals.  In  addition,  the  effects  of  adoption  of  SFAS  No. 123(R),  “Share-Based 
Payment” (“SFAS 123(R)”), combined with additional equity-based awards, resulted in a $14 million increase in 
stock-based compensation expense included in G&A during 2007. Stock-based compensation expense included in 
G&A totaled $25 million in 2007. 

G&A expense increased $64 million, or 64% during 2006 as compared with 2005. The increase was due to higher 
salaries and wages and the inclusion of a full year of G&A expense related to Patina operations. Salaries and wages 
also reflected wage inflation due to a tight labor market and expanded activity across the industry driven by higher 
commodity  prices.  In  addition,  the  effects  of  adoption  of  SFAS  123(R),  combined  with  additional  equity-based 
awards,  resulted  in  a  $7  million  increase  in  stock-based  compensation  expense  included  in  G&A  during  2006. 
Stock-based compensation expense included in G&A was $11 million in 2006 as compared with $4 million in 2005. 

G&A  includes  actuarially-computed  net  periodic  benefit  cost  related  to  pension  and  other  postretirement  benefit 
plans of $17 million in 2007, $19 million in 2006 and $11 million in 2005.

Interest expense, net of capitalized interest, decreased in 2007 primarily due to a declining rate of interest applicable 
to the Credit Facility from 5.69% at December 31, 2006 to 5.28% at December 31, 2007. Interest expense, net of 
capitalized interest, increased in 2006 due to additional borrowings related to the Patina Merger and acquisition of 
U.S. Exploration and to increases in the interest rate applicable to the Credit Facility from 4.82% at December 31, 
2005 to 5.69% at December 31, 2006.  

Interest is capitalized on 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 related to long lead-time projects in West Africa, the North 
Sea and deepwater Gulf of Mexico in 2007; the North Sea and deepwater Gulf of Mexico in 2006; and deepwater 
Gulf of Mexico and projects in West Africa in 2005. 

We  occasionally  enter  into  forward  contracts  or  swap  agreements  to  hedge  exposure  to  interest  rate  risk.  At 
December 31,  2007,  AOCL  included  a  deferred  loss  of  $4 million,  net  of  tax,  related  to  interest  rate  swaps.  $3 
million of 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. The remaining $1 million loss relates to interest 
rate locks that will expire in third quarter 2008. See Item 8. Financial Statements and Supplementary Data—Note 
12—Derivative Instruments and Hedging Activities.

MachalaPower  Cia.  Ltda.,  we  have  a  100%  ownership  interest  in  an  integrated  natural  gas-to-power  project.  The 
project includes the Amistad natural gas field, offshore Ecuador, which supplies fuel to the Machala power plant.

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 net increases in the allowance for doubtful accounts of $14 million in 2007, 
$15 million  in  2006  and  $11 million  in  2005.  These  increases  have  been  made  to  cover  potentially  uncollectible

balances related to the Ecuador power operations. Certain entities purchasing electricity in Ecuador have been slow 
to pay amounts due us. We are pursuing various strategies to protect our interests including international arbitration 
and litigation. 
Gathering, Marketing and Processing—We  market a portion of our US natural gas production, as well as certain 
third-party  natural gas. We  sell  natural  gas  directly  to  end-users, natural  gas  marketers,  industrial users,  interstate 
and intrastate pipelines, power generators and local distribution companies. We also market certain third-party crude 
oil. Gathering, marketing and processing (“GMP”) proceeds are included in other revenues and GMP expenses are 
included in other expense, net in the consolidated statements of operations. Gross margin from GMP activities was

We employ derivative instruments in connection with purchases and sales of third-party production to lock in profits 
or  limit  exposure  to  commodity  price  risk.  Most  of  the  purchases  we  make  are  on  an  index  basis.  However, 
purchasers  in  the  markets  in  which  we  sell  often  require  fixed  or  NYMEX-related  pricing.  We  record  gains  and 
losses on these derivative instruments using mark-to-market accounting. Gains (losses) were de minimis for 2007, 
2006  and  2005.  GMP  proceeds  for  2005  includes  a  gain  of  $11 million  for  the  sale  of  certain  gas  sales  and 
transportation contractual assets. 

Deferred Compensation Expense—In connection with the Patina Merger, 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,  2007,  45%  of  the 
market value of the assets in the rabbi trust related to our common stock. Deferred compensation expense totaled 
$34 million, $16 million and $15 million for 2007, 2006, and 2005, respectively. See Item 8. Financial Statements 
and Supplementary Data—Note 11—Benefit Plans. 

Impairment  of  Operating  Assets—We  recorded  impairments  of  $4  million  in  2007,  $9 million  in  2006  and 
$5 million  in  2005,  primarily  related  to  downward  reserve  revisions  on  proved  US  oil  and  gas  properties  and/or 
adjustment of the carrying value of properties to their fair values. Impairment expense is included in other expense, 
net in the consolidated statements of operations. 

Income Taxes—The income tax provision was as follows:

Several  factors  resulted  in  a  decrease  in  our  effective  tax  rate  for  2007.  The  major  factor  was  that,  in  2006, 
$100 million  of  goodwill  write-off  associated  with  the  sale  of  the  Gulf  of  Mexico  shelf  properties  was  not 
deductible,  which  increased  the  rate  for  2006.  Other  factors  were  an  increase  in  deferred  tax  assets  arising  from 
foreign tax credits, a decrease in the Chinese tax rate, and the realization of additional income from equity method 
investees which is a favorable permanent difference in calculating the income tax expense.   

Our effective tax rate increased significantly in 2006 from 2005 due to several factors. The most significant factor 
was the nondeductible goodwill write-off of $100 million related to the sale of the Gulf of Mexico shelf properties 
discussed in the preceding paragraph. The rate was also impacted by decreases in our US deferred tax assets arising 
from future foreign tax credits due to changes in the limitation on our ability to claim foreign tax credits. In addition, 
a  change  in UK  tax  law  increased our UK tax  expense  in 2006. Offsetting  these  increases  was  a  reduction  in  the 
effective  tax  rate  due  to  an  increase  in  earnings  from  equity  method  investees,  which  is  a  favorable  permanent 
difference in calculating income tax expense.

The 2005 effective tax rate was impacted by our ability to claim a foreign tax credit for the income taxes paid by 
foreign branch operations, as well as a benefit realized on the repatriation of foreign earnings under the American 
Jobs Creation Act of 2004. 

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. We believe that we are well positioned with our mix of crude oil and natural gas reserves to 
take advantage of future price increases that may occur. However, 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 have used 
derivative instruments as a means of managing our exposure to commodity price changes.  

At December 31, 2007, we had entered into variable to fixed price swaps, costless collars and basis swaps related to 
crude  oil  and  natural  gas  sales.  See  Item 8.  Financial  Statements  and  Supplementary  Data—Note  12—Derivative 
Instruments and Hedging Activities. 

As of December 31, 2007, we had a net unrealized loss of $408 million (pre-tax) related to crude oil and natural gas 
derivative  instruments  entered  into  for  hedging  purposes.  A  net  unrealized  loss  of  $255 million,  net  of  tax,  is 
recorded  in  AOCL  in  the  consolidated  balance  sheets.  We  will  reclassify  the  loss  to  earnings  as  adjustments  to 
revenue when future sales occur. 

Interest Rate Risk 

We are exposed to interest rate risk related to our variable and fixed interest rate debt. As of December 31, 2007, we 
had $1.9 billion (excluding unamortized discount) of long-term debt outstanding. Of this amount, $650 million was 
fixed-rate  debt  with  a  weighted  average  interest  rate  of  6.92%.  We  believe  that  anticipated  near  term  changes  in 
interest rates will not have a material effect on the fair value of our fixed-rate debt and will not expose us to the risk 
of earnings or cash flow loss. 

The remainder of our long-term debt, $1.2 billion at December 31, 2007, was variable-rate debt. We also had $25 
million of current installment payments at December 31, 2007. 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, 2007 balance of variable-rate debt would result in a change 
in annual interest expense of approximately $3 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, 2007,  AOCL  included  $4 million,  net  of  tax,  related  to  interest  rate  locks.  A 
portion  of  this  amount  is  being  reclassified  into  earnings  as  adjustments  to  interest  expense  over  the  term  of  our 
5¼% Senior Notes due April 2014. The remainder relates to interest rate locks that are scheduled to settle during 
third  quarter  2008.  See  Item 8.  Financial  Statements  and  Supplementary  Data—Note  12—Derivative  Instruments 
and Hedging Activities. 

We  are  also  exposed  to  interest  rate  risk  related  to  our  short-term  investments.  As  of  December  31,  2007, 
substantially  all  of  our  cash  was  invested  in  highly  liquid,  short-term  investment-grade  securities  with  original 
maturities  of  three  months  or  less  at  the  time  of  purchase.  A  hypothetical  25  basis  point  change  in  the  floating 
interest  rates  applicable  to  the  December  31,  2007  balance would  result  in  a  change  in  annual  interest  income  of 
approximately $2 million. 

Foreign Currency Risk 

We have not entered into foreign currency derivatives. The US dollar is considered the functional currency for each 
of our international operations. Transactions that are completed in a foreign currency are remeasured into US dollars 
and recorded in the financial statements at the prevailing currency exchange rates. We do not have any significant 
monetary  assets  or  liabilities  denominated  in  a  foreign  currency  other  than  our  foreign  deferred  tax  liabilities  in 
certain foreign tax jurisdictions. 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. However, transaction gains or losses were not material in any of the periods presented. We do not believe 
we  are  currently  exposed  to  any  material  risk  of  loss  on  this  basis.  Such  gains  or  losses  are  included  in  other 
expense, net in the consolidated statements of operations.

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, 2007,  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, 2007,  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, 2007 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,  2007  and  2006,  and  the  related  consolidated  statements  of  operations,  shareholders’  equity,  
comprehensive  income  (loss),  and  cash  flows  for  each  of  the  years  in  the  three-year  period  ended  December  31, 
2007.  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  for  the  periods  referred  to  below  of  the  Alba  Plant  LLC  (Alba)  and  the  Atlantic 
Methanol  Production  Company,  LLC  (AMPCO),  the  investments  in  which,  as  disclosed  in  Note  13  of  the 
consolidated financial statements are accounted for by the equity method of accounting.  The Company’s investment 
in Alba as of December 31, 2007 and 2006 was $142.5 million and $146.1 million, respectively, and the equity in 
earnings  in  Alba  was  $128.1  million  and  $101.3  million  for  the  years  ended  December  31,  2007  and  2006, 
respectively.  The  equity  in  earnings  for  AMPCO  was  $54.9  million  for  the  year  ended  December  31,  2005.    The 
financial statements of Alba as of December 31, 2007 and 2006 and for the years then ended and AMPCO for the 
year  ended  December  31,  2005  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 and AMPCO, is based solely on the report 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 report of the 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, 2007 and 2006, and the results of their operations and their cash flows for each of the years in 
the three-year period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.  

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2006, the Company changed its 
method  of  accounting  for  stock-based  compensation.    As  also  discussed  in  Note  2  to  the  consolidated  financial 
statements,  effective  December  31,  2006,  the  Company  changed  its  method  of  accounting  for  defined  benefit 
pension and other postretirement plans.  

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,  2007,  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 25, 2008 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, 2007, 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, 2007, based on criteria established in Internal Control—Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 

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, 2007 and 2006, 
and the related consolidated statements of operations, shareholders’ equity, comprehensive income (loss), and cash 
flows  for  each  of  the  years  in  the  three-year  period  ended  December 31,  2007,  and  our  report  dated  February 25, 
2008 expressed an unqualified opinion on those consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
(Dollar amounts in tables, unless otherwise indicated, are in thousands, except per share amounts) 

Note 1—Nature of Operations 
Noble Energy, Inc. (“Noble Energy”, “we” or “us”) is an independent energy company engaged in the acquisition, 
exploration, development, production and marketing of crude oil and natural gas. We have exploration, exploitation 
and production operations domestically and internationally. We operate throughout major basins in the US including 
Colorado’s  Wattenberg  field  and  Piceance  basin,  the  Mid-continent  area  of  western  Oklahoma  and  the  Texas 
Panhandle, the San Juan basin in New Mexico, the Gulf Coast and the deepwater Gulf of Mexico. In addition, we 
conduct business internationally in China, Ecuador, the Mediterranean Sea, the North Sea, West Africa (Equatorial 
Guinea and Cameroon) and in other areas. In 2005, we merged with Patina Oil & Gas Corporation (“Patina”) and in 
2006 we acquired U.S. Exploration Holdings, Inc. (“U.S. Exploration”). 

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. 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 reserve 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  reserve  estimate  is  a  function  of  the  quality  of 
available data and of engineering and geological interpretation and judgment. As a result, reserve estimates may be 
different from  the quantities of crude oil and natural gas that are ultimately recovered. Engineers in our Houston, 
Denver  and  London  offices  prepare  all  reserve  estimates  for  our  different  geographical  regions.  These  reserve 
estimates are reviewed and approved by senior engineering staff and division management with final approval by 
the  Director  of  Asset  Development  and  certain  members  of  senior  management.  See  Supplemental  Oil  and  Gas 
Information. 

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.  Actual  results  could  differ 
significantly from those estimates. 

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 expense, net on the statements of operations. 

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.

Amounts  charged  to  expense  include  $14 million  in  2007,  $15 million  in  2006  and  $11 million  in  2005  to  cover 
potentially  uncollectible  balances  related  to  Ecuador  power  operations.  These  amounts  are  included  in  electricity 
generation expense. Certain entities purchasing electricity in Ecuador have been slow to pay amounts due us. We are 
pursuing various strategies to protect our interests including international arbitration and litigation. The allowance 
was  also  increased  by  $2 million  in  2006  and  $1 million  in  2005  to  record  various  provisions  related  to  our  US 
business. In addition, in 2005 the allowance was decreased due to the final write-off of certain allowances recorded 
in prior years ($6 million). 

Materials and Supplies Inventories—Materials and supplies inventories, consisting principally of tubular goods and 
production equipment, are stated at the lower of cost or market. 

Property, Plant and Equipment— 
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  are  amortized  to  operations  by  the  unit-of-
production method based on proved crude oil and natural gas reserves on a property-by-property basis as estimated 
by our engineers. 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—In  accordance  with  SFAS No. 144,  “Accounting  for  the  Impairment  or  Disposal  of 
Long-Lived  Assets,”  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 reserve 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  reserves, 
future commodity prices and operating expenses, timing of future production, future capital expenditures and a risk-
adjusted  discount  rate.  We  recorded  impairments  of  approximately  $4 million  in  2007,  $9 million  in  2006  and 
$5 million  in  2005,  primarily  related  to  downward  reserve  revisions  on  US  properties  and/or  adjustment  of  the 
carrying value of properties to their fair values. 

Unproved  Property  Impairment—We  also  periodically  assess  individually  significant  unproved  properties  for 
impairment of value and recognize a loss at the time of impairment by providing an impairment allowance. 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.  We  recorded  impairments  of  individually  significant  unproved  properties  of  approximately  $3 million  in 
2007, $1 million in 2006, and $3 million in 2005 and included the amounts in exploration expense. 

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 reserve 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 

61 

 
           
           
           
             
            
            
 
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 5—Capitalized Exploratory Well Costs. 

Other Property—Other property includes autos, trucks, airplane, office furniture and computer equipment and other 
fixed assets. 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 seven years.

Goodwill—Goodwill represents the excess of the cost of an acquired entity over the net amounts assigned to assets 
acquired and liabilities assumed. We account for goodwill in accordance with SFAS No. 142, “Goodwill and Other 
Intangible  Assets”  (“SFAS  142”).  Goodwill  is  not  amortized  to  earnings  but  is  tested  annually  during  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, 2007. Changes in the carrying amount of goodwill are as

Accounting for Stock Compensation under APB Opinion No. 25 and FASB Interpretation No. 44”, we reduce the 
amount  of  goodwill  originally  recorded  for  deferred  tax  assets  associated  with  the  exercise  of  fully-vested  stock 
options  assumed  in  conjunction  with  the  Patina  Merger  to  the  extent  that  the  stock-based  compensation  expense 
reported for tax purposes does not exceed the fair value of the awards recognized as part of the total purchase price.

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  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 passed. 

Fair Value of Financial Instruments—The following methods and assumptions were used to estimate the fair values 
for each class of financial instruments. The fair value of a financial instrument is the amount at which the instrument 
could be exchanged in a current transaction between two willing parties. 

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 Funds—The fair value is based on published market prices. 

Debt—The fair value of debt is estimated based on the published market prices for the same or similar issues.  The 
carrying amounts and estimated fair values of debt instruments are as follows:

Derivative Instruments—The fair value estimates for commodity fixed price swaps, basis swaps and costless collars use 
published market prices for the underlying commodities and discount rates to determine discounted expected future 
cash flows as of the date of the estimate. See Note 12—Derivative Instruments and Hedging Activities. 

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 $17 million in 2007, $13 million in 2006 and $9 million in 2005. 

Statement of Cash Flows—For purposes of reporting cash flows, cash and cash equivalents include unrestricted cash 
on hand and investments purchased with original maturities of three months or less. 

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

Accounting  for  Uncertainty  in  Income  Taxes  –  We  adopted  FASB  Interpretation  No.  48,  “Accounting  for 
Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (“FIN 48”) as of January 1, 2007. FIN 
48  clarifies  the  accounting  for  uncertainty  in  income  taxes  recognized  in  a  company’s  financial  statements  in 
accordance  with  SFAS  No.  109,  “Accounting  for  Income  Taxes”.  FIN  48  prescribes  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.  FIN  48  also  provides  guidance  on  derecognition,  classification,  interest  and  penalties, 
accounting  in  interim  periods,  disclosure,  and  transition.  We  also  adopted  FASB  Staff  Position  No.  FIN  48-1, 
“Definition of Settlement in FASB Interpretation No. 48” (“FSP FIN 48-1”) as of January 1, 2007. FSP FIN 48-1 
provides  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. The adoption of FIN 48 and FSP FIN 48-1 had no effect on our financial position or results of 
operations. See Note 8—Income Taxes. 

Accounting  for  Stock-Based  Compensation—Through  December 31,  2005,  we  accounted  for  stock-based 
compensation  plans  under  the  intrinsic  value  recognition  and  measurement  principles  of  APB  Opinion  No. 25, 
“Accounting for Stock Issued to Employees” (“APB 25”), and related Interpretations. As of January 1, 2006, we 
adopted  SFAS  No. 123(R),  “Share-Based  Payment”  (“SFAS  123(R)”).  SFAS 123(R)  revised  SFAS  No. 123, 
“Accounting  for  Stock-Based  Compensation”  and  nullified  APB 25  and  its  related  implementation  guidance.

SFAS 123(R) requires  companies  to  measure  the  grant-date  fair  value  of  stock  options  and  other  stock-based 
compensation  issued  to  employees  and  expense  the  fair  value  over  the  requisite  service  period  of  the  award. 
SFAS 123(R) became effective for interim or annual periods beginning January 1, 2006. In accordance with the 
modified  prospective  transition  method,  prior  period  amounts  have  not  been  restated.  See  Note  9—Stock-Based 
Compensation. 

Accounting  for  Defined  Benefit  Pension  and  Other  Postretirement  Plans—In  September 2006,  the  Financial 
Accounting  Standards  Board  (the  “FASB”)  issued  SFAS  No. 158,  “Employers’  Accounting  for  Defined  Benefit 
Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 
158”).  SFAS  158  requires  plan  sponsors  of  defined  benefit  pension  and  other  postretirement  benefit  plans  to 
recognize the funded status of their postretirement benefit plans in the statement of financial position, measure the 
fair value of plan assets and benefit obligations as of the date of the fiscal year-end statement of financial position, 
and provide additional disclosures. We adopted SFAS 158 as of December 31, 2006, and the effect of adoption on 
our financial condition at December 31, 2006 was included in our consolidated balance sheets. Adoption of SFAS 
158 had no effect on our results of operations for the year ended December 31, 2006. See Note 11—Benefit Plans. 

Adoption  of  Staff  Accounting  Bulletin  No. 108—In  September 2006,  the  Securities  and  Exchange  Commission 
(“SEC”)  issued  Staff  Accounting  Bulletin  No. 108  (“SAB  108”).  SAB  108  expresses  the  SEC  staff’s  views 
regarding  the  process  of  quantifying  financial  statement  misstatements.  The  SEC  staff  believes  registrants  should 
quantify errors using both a balance sheet and an income statement approach and evaluate whether either approach 
results  in  quantifying  a  misstatement  that,  when  all  relevant  quantitative  and  qualitative  factors  are  considered,  is 
material.  SAB 108 is effective for fiscal years ending on or after November 15, 2006. We adopted SAB 108 as of 
December 31, 2006. Adoption of SAB 108 had no effect on our financial position or results of operations. 

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

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

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. We 
record  the  noncurrent  portion  of  the  liability  in  other  deferred  credits  and  noncurrent  liabilities,  and  the  current 
portion of the liability in other current liabilities. We record the noncurrent portion of the receivable in other assets 
and  the  current  portion  of  the  receivable  in  other  current  assets.  Imbalance  liabilities  were  $10  million  and 
$17 million at December 31, 2007 and 2006, respectively. Imbalance receivables were $13 million and $18 million 
at December 31, 2007 and 2006, respectively. 

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. 

Derivative  Instruments  and  Hedging  Activities—We  use  various  derivative  instruments  in  connection  with 
anticipated crude oil and natural gas sales to minimize the impact of commodity price fluctuations. Such instruments 
include variable to fixed NYMEX price swaps, costless collars and variable to fixed price basis swaps. We account 
for  derivative  instruments  and  hedging  activities  in  accordance  with  SFAS  No. 133,  “Accounting  for  Derivative 
Instruments and Hedging Activities, as amended,” (“SFAS 133”). SFAS 133 established accounting and reporting 
standards  requiring  every  derivative  instrument  (including  certain  derivative  instruments  embedded  in  other 
contracts)  to  be  recorded  on  the  balance  sheet  as  either  an  asset  or  liability  measured  at  fair  value.  SFAS  133 
requires  that  changes  in  the  derivative’s  fair  value  be  recognized  currently  in  earnings  unless  specific  hedge 
accounting criteria are met. Under cash flow hedge accounting, gains and losses are reflected in shareholders’ equity 
as  accumulated  other  comprehensive  income  or  loss  (“AOCL”)  until  the  forecasted  transaction  occurs.  The 
derivative’s  gains  and  losses are  then offset  against  related results on  the  hedged  transaction on  the  statements  of 
operations. Gains and losses from derivative instruments related to crude oil and natural gas sales and which qualify 

66 

 
for hedge accounting treatment are recorded in oil and gas sales in the consolidated statements of operations upon 
sale of the associated commodity. 

SFAS 133 also requires that a company 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. We 
assess  hedge  effectiveness  quarterly  based  on  total  changes  in  the  derivative’s  fair  value  and  using  regression 
analysis. A hedge is considered effective if certain statistical tests are met. We record hedge ineffectiveness in loss 
on derivative instruments. See Note 12—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  discontinued  cash  flow  hedge  accounting  on  all  existing  commodity 
derivative  instruments.  We  voluntarily  made  this  change  to  provide  greater  flexibility  in  our  use  of  derivative 
instruments. From January 1, 2008 forward, we will 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,  will  be 
reclassified to earnings in future periods as the original hedged transactions affect earnings. 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 
does not require adjustments to our previously reported financial statements. 

Related Party Transaction—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,  the  Board  member  served  as  a 
consultant to the combined company for a period of 12 months following the merger (May 16, 2005) in exchange 
for a monthly retainer of $50,000. We paid total consulting fees of $225,806 during 2006 and $374,194 during 2005. 
We also reimbursed his office space rent of $72,000 in 2006 and $45,000 in 2005. 

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. 

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. 

Electricity  Generation—Ecuador  Integrated  Power  Project—Through  our  subsidiaries,  EDC  Ecuador  Ltd.  and 
MachalaPower  Cia.  Ltda.,  we  have  a  100%  ownership  interest  in  an  integrated  natural  gas-to-power  project.  The 
project  includes  the  Amistad  natural  gas  field,  offshore  Ecuador,  which  supplies  natural  gas  to  fuel  the  Machala 
power plant located in Machala, Ecuador. The revenues attributable to the natural gas-to-power project are included 
in other revenues and the expenses (including DD&A) are included in other expense, net. 

Concentration of Market Risk—During 2007, Marathon Petroleum Supply Company (“Marathon”) was the largest 
single non-affiliated purchaser of production and accounted for 18% of crude oil sales, or 10% of total oil and gas 
sales.  During  2006,  Trafigura  Beheer  B.V.  was  the  largest  single  non-affiliated  purchaser  of  production  and 
accounted for 28% of crude oil sales, or 15% of total oil and gas sales. Shell Trading (US) Company accounted for 
18% of 2006 crude oil sales or 10% of 2006 total oil and gas sales. During 2005, Glencore Energy U.K., Ltd. was 
the largest single non-affiliated purchaser of production and accounted for 24% of crude oil sales, or 11% of total oil 
and gas sales. We believe the loss of any one purchaser would not have a material effect on our financial position or 
results of operation since there are numerous potential purchasers of our production. 

Concentration of Credit Risk—Certain of our financial instruments, including cash equivalents, trade receivables and 
derivative instruments, may expose us to credit risk.  Substantially all of our cash at December 31, 2007 is located in 
our foreign subsidiaries. The cash is denominated in US dollars and in invested in highly liquid, investment-grade 
securities  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. 

67 

 
Our trade receivables result primarily from sales of crude oil and natural gas production and joint interest billings to 
our  partners.  The  trade  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, 
and we continually monitor the creditworthiness of the counterparties.  

We use crude oil and 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.  We  engage  in  master  netting  arrangements  to  mitigate  credit  risk  with  counterparties  as  these 
agreements permit the amounts owed to others to be offset against amounts due us. We monitor the creditworthiness 
of our counterparties and believe that losses from nonperformance are unlikely to occur. However, we are not able 
to predict sudden changes in counterparties’ creditworthiness. 

Reclassification—Certain reclassifications have been made to the 2006 and 2005 consolidated financial statements 
to conform to the 2007 presentation. These reclassifications are not material to the financial statements. 

Note 3—Acquisitions and Divestitures 

Sale  of  Argentina—In  December  2007,  we  entered  into  an  agreement  to  sell  our  interest  in  Argentina  for  a  sales 
price  of  $117.5  million,  effective  July  1,  2007.  We  expect  the  sale,  which  is  subject  to  regulatory  and  partner 
approvals, to close in 2008. The Argentina assets had a net book value of $82 million at December 31, 2007 and are 
classified as assets held for sale in the consolidated balance sheets. The Argentina operations, financial position and 
cash flows are not material and have not been reflected as discontinued operations. 

Sale of Gulf of Mexico Shelf Properties—In 2006, we completed the sale of our Gulf of Mexico shelf properties. The 
sale included essentially all of our properties in the Gulf of Mexico shelf except for our interest in the Main Pass 
area, which we have retained. Pretax cash proceeds from the sale totaled $506 million including proceeds received 
from  parties  who  exercised  preferential  rights  to  purchase  certain  minor  properties.  We  recorded  a  pretax  gain  of 
$211 million from the sale. The net book value of properties sold totaled $229 million. Asset retirement obligations 
of  $45 million,  related  to  the  Gulf  of  Mexico  shelf  properties,  were  also  included  in  the  sale.  In  accordance  with 
SFAS 142, we allocated $100 million of our US reporting unit goodwill to the sale. The property disposition did not 
qualify  for  accounting  as  discontinued  operations,  in  accordance  with  EITF  03-13,  “Applying  the  Conditions  in 
Paragraph 42 of FASB Statement No. 144 in Determining Whether to Report Discontinued Operations”. This is due 
to the migration of our investment and operations to the deepwater Gulf of Mexico which we believe is an area of 
higher potential. 

As a result of the sale, we recognized a pretax charge of $399 million related to cash flow hedge losses which were 
reclassified  from  AOCL  to  earnings.  This  reclassification  reflected  the  mark-to-market  value  of  the  cash  flow 
hedges  that  related  to  Gulf  of  Mexico  shelf  production.  See  Note  12—Derivative  Instruments  and  Hedging 
Activities. 

Purchase  of  U.S.  Exploration  Holdings, Inc.—In  2006,  we  purchased  the  common  stock  of  U.S.  Exploration,  a 
privately  held  corporation,  for  a  cash  purchase  price  of  $412 million  plus  liabilities  assumed.  U.S.  Exploration’s 
reserves  and production  are  located  in  Colorado’s Wattenberg field.  The  total  purchase  price  was  allocated  to  the 
assets acquired and liabilities assumed based on fair values at the acquisition date as follows: 

•  $413 million to proved oil and gas properties; 
•  $131 million to unproved oil and gas properties; 
•  $34 million to goodwill; and 
•  $172 million to deferred income taxes. 

Patina Merger—In 2005, we completed the Patina Merger. Patina was an independent energy company engaged in 
the  acquisition,  development  and  exploitation  of  crude  oil  and  natural  gas  properties  within  the  continental  US. 
Patina’s  properties  and  oil  and  gas  reserves  are  located  principally  in  relatively  long-lived  fields  with  established 
production histories. The properties are concentrated primarily in the Wattenberg field of Colorado’s D-J basin, the 
Mid-continent  area  of  western  Oklahoma  and  the  Texas  Panhandle,  and  the  San  Juan  basin  in  New  Mexico.  We 
acquired the common stock of Patina for a total purchase price of approximately $4.9 billion, which was comprised 
primarily of cash and our common stock, plus liabilities assumed. In exchange for Patina’s common stock and stock 
options  held  by  Patina’s  employees,  we  issued  55.7 million  shares  of  stock  valued  at  $1.7 billion,  issued  options 
valued  at  $105 million,  paid  $1.1 billion  in  cash  to  Patina  shareholders  and  assumed  debt  of  $611 million  and 

68 

 
 
 
deferred taxes of $1.1 billion. The total purchase price was allocated to the assets acquired and liabilities assumed 
based on fair values at the merger date as follows: 

•  $2.6 billion to proved oil and gas properties; 
•  $1.1 billion to unproved oil and gas properties; 
•  $875 million to goodwill; and 
•  $1.1 billion to deferred income taxes. 

The  following  pro  forma  condensed  combined  financial  information  for  the  year  ended  December 31,  2005  was 
derived  from  our  historical  financial  statements  and  those  of  Patina  and  gives  effect  to  the  merger  as  if  it  had 
occurred  on  January 1,  2005.  The  financial  information  has  been  included  for  comparative  purposes  and  is  not 
necessarily indicative of the results that might have occurred had the merger taken place as of the dates indicated 
and is not intended to be a projection of future results.

Note 4—Effect of Gulf Coast Hurricanes 

We have completed our cleanup activities relating to damage to the Main Pass assets caused by Hurricane Ivan in 
2004 and Katrina in 2005.  During third quarter 2007, we completed the lifting and removal of the four platform 
decks that were sheared from their supporting structures during the hurricanes. During the first half of 2007, several 
factors contributed to an increase in our estimated cleanup costs for damage related to Hurricanes Ivan and Katrina.  
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  during 
2007.   

Through  December  31,  2007,  we  received  $310  million  of  insurance  recoveries  related  to  damage  caused  by 
Hurricanes Ivan and Katrina. As of December 31, 2007, we recorded probable insurance claims of $40 million. We 
are currently assessing the scope and timing of our redevelopment of the Main Pass properties. Ultimate recovery of 
our insurance claim is associated with redevelopment or possible settlement resolution with our insurance providers. 

Insurance  reimbursements  received  to date have  been for cleanup  and  repair  costs  and are  included  in  cash flows 
from operating activities.

Exploratory well costs capitalized for more than one year at December 31, 2007 included six projects, two of which 
included activity in the deepwater Gulf of Mexico.  One project relates to Raton South (Mississippi Canyon Block 
292)  and  includes  approximately  $23  million  of  suspended  exploratory  well  costs.  We  are  currently  evaluating  a

possible  sidetrack-appraisal  well  to  be  drilled  during  late  2008  or  2009.    The  other  project  relates  to  Redrock 
(Mississippi Canyon 248) and includes approximately $17 million of suspended exploratory well costs. Redrock is 
currently considered a co-development candidate to a successful sidetrack-appraisal well at Raton South. 

We also incurred exploratory well costs for projects, Block O and Block I, in West Africa. These exploratory well 
costs totaled approximately $19 million. Since drilling the initial well for the project, additional seismic work has 
been completed and appraisal wells have been drilled to further evaluate this discovery. In 2008, the West Africa 
development  team  will  proceed  with  a  program  to  further  define  the  resources  in  this  area  such  that  an  optimal 
development  program  may  be  designed.  In  addition  to  the  amount  of  exploratory  well  costs  that  have  been 
capitalized for a period greater than one year for the Block O and Block I projects, we incurred $137 million related 
to the six successful wells drilled in West Africa during 2007. 

The  remaining  two  projects,  which  total  approximately  $2  million,  continue  to  be  evaluated  by  various  means 
including additional seismic work, drilling additional wells and evaluating the potential of the exploration wells. 

Note 6—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:

changes in estimated timing of actual abandonment and overall cost increases for Gulf of Mexico assets. See Note

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  the  7¼%  Notes,  the  8%  Senior  Notes  and  the  7¼% 
Senior  Debentures  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. 

Credit  Facility—In  November  2007,  we  extended  our  bank  revolving  credit  facility  (the  “Credit  Facility”)  until 
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. 
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. 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.  Debt  issuance  costs  of  approximately  $3 million  remain  and  are  being  amortized  to 
expense over the life of the Credit Facility. 

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. 

Installment Payments Due—During 2007, we purchased working interests in oil and gas properties in the Piceance 
basin  of  western  Colorado  for  $75  million.  After  making  a  cash  payment  of  $25  million  at  closing,  we  owe  $50 
million in the form of installment payments to the seller. Installments of $25 million each are due on May 12, 2008 
and May 11, 2009.  The amount due in 2008 is included in short-term borrowings and the amount due in 2009 is 
included  in  long-term  debt  in  the  consolidated  balance  sheets.  Interest  on  the  unpaid  amounts  is  due  quarterly. 
Interest accrues at a LIBOR rate plus .30%. The interest rate was 5.53% at December 31, 2007. 

Debt  Repayments—During  2006,  we  prepaid  the  $105 million  balance  remaining  on  certain  term  loans  due  2009. 
The interest rates on the term loans were based on a Eurodollar rate plus a margin of between 60 to 130 basis points

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

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 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, 2007. The amount of the deferred 
tax  asset  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  effect  of  these 
carryforwards  decreased  from  $90 million  in  2006  to  $18 million  in  2007.  These  losses  were  incurred  on  our 
projects  in  Suriname  and  other  new  venture  activities  which  are  not  yet  commercial.  Therefore,  a  valuation 
allowance was provided against the full amount of the deferred tax asset. In 2006, we incurred a large taxable loss 
in the UK from accelerated write-offs allowed on our Dumbarton field development. No valuation allowance was 
provided against this loss carryforward, and it was fully utilized in 2007. Starting in 2005, we were able to claim a 
foreign tax credit for US federal income tax purposes and expect to be in a credit position for the next several years. 
Therefore,  we  have  recorded  a  deferred  tax  asset  for  certain  foreign  taxes  paid  in  2005  and  2006  that  cannot  be 
claimed  as  a  credit  in  those  years  because  of  limitations  imposed  by  the  Internal  Revenue  Code.  A  valuation 
allowance  of  $11 million  has  been  provided  against  this  deferred  tax  asset.  We  have  also  recorded  a  deferred  tax 
asset  of  $71 million  for  the  future  foreign  tax  credits  associated  with  deferred  tax  liabilities  recorded  by  foreign 
branch operations. A valuation allowance of $46 million has been provided against this deferred tax asset. 

Several  factors  resulted  in  a  decrease  in  our  effective  tax  rate  for  2007.  The  major  factor  was  that,  in  2006, 
$100 million  of  goodwill  write-off  associated  with  the  sale  of  the  Gulf  of  Mexico  shelf  properties  was  not 
deductible, which increased the rate for that year. Other factors were an increase in deferred tax assets arising from 
foreign tax credits, a decrease in the Chinese tax rate, and the realization of additional income from equity method 
investees which is a favorable permanent difference in calculating the income tax expense.   

The American Jobs Creation Act (“AJCA”), enacted in 2004, created a temporary incentive for US corporations to 
repatriate  accumulated  income  earned  abroad  by  providing  for  an  85%  dividends-received  deduction  for  certain 
dividends  from  controlled  foreign  corporations.  In  July 2005,  we  completed  an  evaluation  of  the  effects  of  the 
repatriation  provision,  and  our  Board  of  Directors  approved  a  plan  to  repatriate  $118 million  in  earnings  of  our 
methanol  subsidiary  during  the  third  quarter  2005.  Because  we  had  provided  US  tax  on  most  of  the  methanol 
subsidiary’s earnings at 35% through December 31, 2004, repatriation under the Act resulted in a net tax benefit of 
$35 million recorded in the third quarter 2005. 

We have not recorded US deferred income taxes on the remaining undistributed earnings of foreign subsidiaries as 
of  December 31, 2007.  As  of  December 31, 2007,  the  accumulated  undistributed  earnings  of  the  consolidated 
foreign subsidiaries were approximately $902 million. Upon distribution of these 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 estimate 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. 

During 2007, China’s legislature, the National People’s Congress, enacted the China Corporate Income Tax Law.  
This new legislation will decrease our tax rate in China from 33% to 25% starting in 2008.  The deferred tax liability 
for China as of December 31, 2006 was revised during 2007 to reflect the new rate, which decreased deferred tax 
expense by $2 million. 

Adoption of FIN 48 and FSP FIN 48-1—As discussed in Note 2—Significant Accounting Policies, we adopted FIN 
48  and  FSP  FIN  48-1  as  of  January  1,  2007.  The  adoption  had  no  effect  on  our  financial  position  or  results  of 
operations. As of January 1, 2007, the total amount of unrecognized tax benefits was $400,000, all of which would 
affect our effective tax rate if recognized. There was no change in the amount of unrecognized tax benefits through 
December 31, 2007. 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  –  2004, 
Equatorial Guinea – 2006, China – 2006, Israel – 2000, UK – 2006 and the Netherlands – 2005.

We recognize interest and penalties related to unrecognized tax benefits which have been claimed on tax returns in 
income tax expense. We did not accrue interest or penalties at December 31, 2007, 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. 

Note 9—Stock-Based Compensation 

As  discussed  in  Note  2—Summary  of  Significant  Accounting  Policies,  effective  January 1,  2006,  we  adopted  the 
fair  value  recognition  provisions  for  stock-based  awards  granted  to  employees  using  the  modified  prospective 
application  method  provided  by  SFAS  123(R).  Accordingly,  prior  period  amounts  have  not  been  restated. 
SFAS 123(R) requires  companies  to  recognize  in  the  statement  of  operations  the  grant-date  fair  value  of  stock 
options  and  other  stock-based  compensation  issued  to  employees  and  was  effective  for  interim  or  annual  periods 
beginning  January 1,  2006.  We  recognize  the  expense  of  all  stock-based  awards  on  a  straight-line  basis  over  the 
employee’s requisite service period (generally the vesting period of the award). 

We recognized total stock-based compensation expense as follows:

Stock  Option  and  Restricted  Stock  Plans  and  Incentive  Plan—Our  stock  option  and  restricted  stock  plans  (the 
“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. During 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 18,500,000 to 22,000,000 shares. At December 31, 2007, 11,229,753 shares 
of  common  stock  were  reserved  for  issuance,  including  6,063,665  shares  available  for  future  grants  and  awards, 
under the 1992 Plan. 

1992 Plan Stock Options—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. 

1992  Plan  Restricted  Stock—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 periods of one to three years. 

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 the provisions of SFAS 
123(R) which provides for the grant-date fair value of the awards to be recognized in the income statement over the 
service  period.  Our  cash  based  performance  units  are  accounted  for  under  SFAS  No. 5,  “Accounting  for 
Contingencies” and are excluded from the provisions of SFAS 123(R). 

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 common stock 
that may be issued under the 2005 Plan is 800,000. At December 31, 2007, 774,561 shares of common stock were 
reserved for issuance, including 650,306 shares available for future grants and awards under the 2005 Plan. 

2005  Plan  Stock  Options—The  2005  Plan  provides  for  the  granting  to  a  non-employee  director  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 (up to a maximum of 11,200 options 
per non-employee director granted in any one year). 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. 

2005  Plan  Restricted  Stock—The  2005  Plan  also  provides  for  the  granting  to  a  non-employee  director  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  grants  by  the  Board  of 
Directors (up to a maximum of 4,800 shares of restricted stock per non-employee director awarded in any one year). 
Restricted stock is restricted for a period of at least one year from the date of grant. 

1988 Nonqualified Stock Option Plan for Non-Employee Directors 

The  1988  Nonqualified  Stock  Option  Plan  for  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 

77 

 
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. No options can be granted under the 1988 Plan after its termination. 

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  market  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 Patina options expire five years 
from the date of grant. See Note 3—Acquisitions and Divestitures. 

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 uses the assumptions noted in the following table. The expected term 
represents the period of time that options granted are expected to be outstanding. The hypothetical midpoint scenario 
we  use  considers  the  actual  exercise  and  post-vesting  cancellation  history  of  stock-based  compensation  historical 
trends to develop expectations for future periods. Expected volatility represents the extent to which our stock price is 
expected to fluctuate between the grant date and the anticipated term of the award. We use a blended ratio of the 
historical  volatility  of  our  common  stock  for  a  period  equal  to  the  expected  term  of  the  option  and  the  implied 
volatility from exchange-traded options on our common stock. The risk-free rate is based on a weighting of five and 
seven  year  US  Treasury  securities  as  of  the  year  ended  prior  to  the  date  of  grant  to  arrive  at  an  approximated 
5.5-year  risk  free  rate  of  return.  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 assumptions used in valuing stock options are as follows:

The weighted-average grant-date fair value of options granted was $18.77 in 2007, $16.09 in 2006 and $12.17 in 
2005. The total intrinsic value of options exercised was $68 million in 2007, $118 million in 2006 and $78 million 
in 2005.

As  of  December 31,  2007,  $23 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 common stock to settle option exercises. Dividends are not paid on unexercised options. 

Restricted Stock Awards—Awards of time-vested restricted stock are valued at the price of our common stock at the 
date of award. The fair values of market-based restricted stock awards are estimated on the date of award using a 
Monte Carlo valuation model that uses the assumptions in the following table. The Monte Carlo model is based on 
random projections of stock price paths and must be repeated numerous times to achieve a probabilistic assessment. 
Expected  volatility  represents  the  extent  to  which  our  stock  price  is  expected  to  fluctuate  between  now  and  the 
award’s anticipated term. We use the historical volatility of our common stock for the three-year period ended prior 
to the date of award. The risk-free rate is based on a three-year period from US Treasury securities as of the year 
ended prior to the date of award.  The assumptions used in valuing the market based restricted stock awards are as 
follows:

The total fair value of restricted stock that vested was $6 million in 2007 and $2 million in 2006.  

As of December 31, 2007, $20 million of compensation cost related to unvested restricted stock awarded under the 
Plans  remained  to  be  recognized.  The  cost  is  expected  to  be  recognized  over  a  weighted-average  period  of  two 
years. Common stock dividends accrue on restricted stock grants and are paid upon vesting. We issue new shares of 
common stock when awarding restricted stock.

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. 

Former Patina employees began participation in the pension plan and the restoration plan on January 1, 2006, with 
vesting service from their original Patina hire date and credited service for benefit accruals starting January 1, 2006. 
Additionally,  all  former  Patina  employees  were  covered  under  the  medical  and  life  insurance  plans  effective 
January 1, 2006. 

On  December 31,  2006,  we  adopted  SFAS  158,  which  required  us  to  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 sheet, with a corresponding adjustment to AOCL, net of tax. 
The  adjustment  to  AOCL  at  adoption  represented  the  unrecognized  net  actuarial  loss,  unrecognized  prior  service 
cost, and unrecognized net transition obligation remaining from the initial adoption of SFAS No. 87, “Employers’ 
Accounting  for  Pensions”  and  SFAS  No. 106,  “Employers’  Accounting  for  Post-Retirement  Benefits  Other  Than 
Pensions”.  These  amounts  are  currently  being  recognized  as  net  periodic  benefit  cost  pursuant  to  our  historical 
accounting policy for amortizing such amounts. Further, actuarial gains and losses that arise in periods subsequent to 
adoption and are not recognized as net periodic benefit cost in the same periods are recognized as a component of 
AOCL. The adoption of SFAS 158 had no effect on our consolidated statements of operations for the year ended 
December 31, 2006, for any prior period presented, or for any periods subsequent to adoption.

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 expect pension assets will earn an average of 8.25% per annum 
over the life of the plan. No plan assets are expected to be returned to us during 2008. 

In order to determine an appropriate discount rate at December 31, 2007, 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 
$4 million in 2007. A 1% decrease in the discount rate would have resulted in an increase in net periodic benefit cost 
of $5 million in 2007. 

Assumed health care cost trend rates were as follows at December 31: 

Health care cost trend rate assumed for next year
Rate to which the cost trend rate is assumed to decline (ultimate trend rate)
Year rate reaches ultimate trend rate

2007
9%
5%
2012

2006
10%
5%

Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans. A one-
percentage-point change in assumed health care cost trend rates would have the following effects: 

Effect on total service and interest cost components for 2007
Effect on year-end 2007 postretirement benefit obligation

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. 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 $1 million in 2007. 

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, 2007, we had cumulative asset gains of approximately $3 million, which remain to be recognized in the 
calculation of the market-related value of assets.  

Contributions—As a result of previous contributions made to the pension plan, there are no required contributions 
expected during 2008. We may, however, make additional contributions to our pension plan as determined by the 
committee.  We  expect  to  make  cash  contributions  of  approximately  $4 million  to  the  unfunded  restoration  and 
medical and life plans during 2008. This amount equals expected benefit payments from those plans. (unaudited). 

Estimated Future Benefit Payments—As of December 31, 2007, the following future benefit payments are expected 
to be paid: 

2008
2009
2010
2011
2012

The  estimate  of  expected  future  benefit  payments  is  based  on  the  same  assumptions  used  to  measure  the  benefit 
obligation at December 31, 2007 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 $6 million in 2007, $4 million in 2006 and $5 million in 2005. 

Deferred  Compensation  Plan—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. We account for the deferred compensation plan 
in accordance with EITF 97-14, “Accounting for Deferred Compensation Arrangements Where Amounts Earned are 
Held in a Rabbi Trust and Invested.” Components of the rabbi trust are as follows: 

Rabbi trust assets

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 market value. We account for these investments in accordance with SFAS No. 115, “Accounting for 
Certain Investments in Debt and Equity Securities.” The mutual funds are included in the mutual funds 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 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. One million shares, or 91%, of the common stock held 
in  the  plan  at  December 31,  2007  and  2006  were  attributable  to  a  member  of  our  Board  of  Directors.  Plan 
participants sold no shares of common stock during 2007, 1,067,948 shares during 2006 and 20,434 shares during 
2005.  Proceeds  were  invested  in  mutual  funds.  Distributions  to  plan  participants  totaled  $2  million  in  2007, 
$0.5 million in 2006 and $1 million in 2005. 

In  accordance  with  EITF  97-14,  all  fluctuations  in  market  value  of  the  deferred  compensation  liability  have  been 
reflected  in  other  expense,  net  in  the  consolidated  statements  of  operations.  The  market  value  of  the  liability 
increased $41 million in 2007, $28 million in 2006 and $18 million in 2005. The increases in the liability included 
the  appreciation  in  the  market  value  of  our  common  stock  of  $34  million  in  2007,  $16  million  in  2006  and  $15 
million in 2005. The increases in the liability also included the appreciation in the market value of the rabbi trust 
mutual  fund  investments  of  $7  million  in  2007,  $12 million  in  2006  and  $3 million  in  2005.  Net  deferred 
compensation expense totaled $34 million, $16 million and $15 million in 2007, 2006 and 2005, respectively. 

Note 12—Derivative Instruments and Hedging Activities 

Cash Flow Hedges—We use various derivative instruments in connection with anticipated crude oil and natural gas 
sales  to  mitigate  the  variability  of  cash  flows  associated  with  commodity  price  fluctuations.  Such  instruments 
include  variable  to  fixed  price  swaps,  costless  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 SFAS 133 and 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, we voluntarily discontinued cash flow hedge 
accounting for our commodity derivative instruments, effective January 1, 2008. 

(Gain) loss on derivative instruments includes the following: 

Ineffectiveness (gains) losses
Reclassified from AOCL
Mark-to-market gain on derivative instruments
   not accounted for as cash flow hedges

If  it  becomes  probable  that  the  hedging  instrument  is  no  longer  highly  effective,  the  hedging  instrument  loses 
hedge  accounting  treatment.  All  current  mark-to-market  gains  and  losses  are  recorded  in  earnings  and  all 
accumulated gains or losses recorded in AOCL related to the hedging instrument are also reclassified to earnings. 
During 2006, we reclassified a pretax charge of $399 million from AOCL to earnings when it became probable that 
forecasted crude oil and natural gas sales would not occur due to the sale of Gulf of Mexico shelf properties. 2006 
also  included  a  mark-to-market  gain  of  $39  million  and  the  reclassification  a  pretax  charge  of  $25  million  from 
AOCL to earnings due to the impacts of Hurricanes Katrina and Rita on the timing of forecasted Gulf of Mexico 
production. During 2005, we recognized a mark-to-market gain of $20 million and reclassified a pretax charge of 
$52 million from AOCL to earnings due to the impact of Hurricanes Katrina and Rita on forecasted Gulf of Mexico 
production. 

Effects of cash flow hedges included in oil and gas sales were as follows:    

Decrease in crude oil sales
Increase (decrease) in natural gas sales
Total decrease in crude oil and natural gas sales

The costless collar, fixed price swap and basis swap contracts entitle us (floating price payor) to receive settlement 
from  the  counterparty  (fixed  price  payor)  for  each  calculation  period  in  amounts,  if  any,  by  which  the  settlement 
price for the scheduled trading days applicable for each calculation period is less than the fixed price or floor price. 
We would pay the counterparty if the settlement price for the scheduled trading day 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 the fixed or floor price over the floating price in respect of each calculation period. 

AOCL—As of December 31, 2007 and 2006, the balance in AOCL included net deferred losses of $255 million and 
$104 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 $153 million and $63 million, 
respectively. Approximately $206 million of these deferred losses, net of tax, will be reclassified to earnings during 
the next twelve months as the forecasted transactions occur, and will be recorded as a reduction in oil and gas sales 
of approximately $331 million before tax. All forecasted transactions currently being hedged are expected to occur 
by December 2010. 

Other Derivative Instruments—In addition to the derivative instruments described above, we may employ derivative 
instruments in connection with purchases and sales of production in order to establish a fixed margin and mitigate 
the risk of price volatility. Most of the purchases are on an index basis. However, purchasers in the markets in which 
we sell often require fixed or NYMEX-related pricing. We may use a derivative instrument to convert the fixed or 
NYMEX sale to an index basis thereby determining the margin and minimizing the risk of price volatility. 

Receivables/Payables Related to Crude Oil and Natural Gas Derivative Instruments—The fair values of derivative 
instruments included in the consolidated balance sheets are as follows: 

Crude oil and natural gas derivative instruments

Long-term asset

Interest Rate Lock—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,  2007,  AOCL  included  a

deferred loss of $4 million, net of tax, related to interest rate swaps. $3 million of 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. The remaining $1 million deferred loss relates to two $500 million notional amount interest 
rate  locks  based  on  five  and  ten  year  US  Treasury  rates  of  3.55%  and  4.15%,  respectively.  The  locks  expire  in 
September 2008.  

Note 13—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. 

Construction of the Alba Plant was funded primarily through advances by us and other owners in exchange for notes 
payable  by  the  Alba  Plant.  The  notes  were  scheduled  to  mature  on  December 31,  2011  and  bore  interest  at  the 
90-day LIBOR rate plus 3%. The notes were repaid in 2006.  

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,  2007,  our  retained  earnings  included  $151 million  related  to  the  undistributed  earnings  of  equity 
method investees. 

The  carrying  value  of  our  equity  method  investments  is  $29 million  higher  than  the  underlying  net  assets  of  the 
investees.  A  portion of  the basis  difference  is  being  amortized  into  income  over  the  remaining useful  lives  of  the 
underlying net assets and the remainder is being recovered through distributions.

Legal  Proceedings—We  are  among  a group  of  eighteen  defendants  named  in  a  lawsuit  filed  August  23, 2002  by 
Dore  Energy  Corporation  under  Docket  Number  10-16202  in  the  38th  Judicial  District  Court,  Cameron  Parish, 
Louisiana.  The lawsuit alleges damage to property owned by Dore resulting from oil and gas activities dating to the 
1930’s.  Our predecessor, Samedan Oil Corporation, operated on a portion of the property from 1989 to 1999.  Dore 
has delivered documents alleging approximately $140 million in damages. Trial is currently set for April 14, 2008. 
We intend to vigorously defend against these allegations and believe that our share of damages, if any, will not have 
a material adverse effect on our results of operations, financial condition or liquidity. 

The  Illinois  Environmental  Protection  Agency  (“IEPA”)  issued  a  notice  of  violation  to  Equinox  Oil  Company  on 
September 25, 2001 alleging violation of air emission and permitting regulations for a facility known as the Zif Gas 
Plant  located  near  Clay  City,  Illinois.    On  January  17,  2007,  the  IEPA  re-issued  written  notices  of  these  alleged 
violations  in  the  name  of  Equinox’s  successors  in  interest,  and  our  wholly-owned  subsidiaries,  Elysium  Energy, 
LLC  and  Noble  Energy  Production,  Inc.  On  March  16,  2007,  the  IEPA  accepted  our  compliance  commitment 
agreement wherein we agreed to pay a delayed permit fee, install an incineration/caustic scrubber emissions control 
system at the site, and fund a supplemental environmental project (“SEP”) in the nearby community.  At this time, 
we expect no additional monies to be expended other than these amounts for which we have fully accrued.  As of 
December 31, 2007, this matter has been concluded. 

We are involved in various 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 do not 
believe  that  the  ultimate  disposition  of  such  proceedings  will  have  a  material  adverse  effect  on  our  consolidated 
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 properties. Rental expense for office buildings and oil and gas operations equipment 
was approximately $13 million in 2007, $12 million in 2006 and $10 million in 2005.

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  natural  gas  and  crude  oil  exploration  and 
production: the United States; West Africa; the North Sea; Israel; and Other International, Corporate and Marketing. 
Other International includes Argentina, China, Ecuador and Suriname. 

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 16—Recently Issued Pronouncements 

SFAS 141(R) and SFAS 160 – In December 2007, the FASB issued SFAS 141(R), “Business Combinations” (SFAS 
141(R)”)  and  SFAS  160,  “Noncontrolling  Interests  in  Consolidated  Financial  Statements”  (SFAS  160”).  These 
statements  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.  Both  statements  are  effective  for 
periods beginning on or after December 15, 2008, and earlier adoption is prohibited. SFAS 141(R) will be applied to 
business  combinations  occurring  after  the  effective  date  and  SFAS  160  will  be  applied  prospectively  to  all 
noncontrolling  interests,  including  any  that  arose  before  the  effective  date.  We  are  currently  evaluating  the 
provisions of SFAS 141(R) and SFAS 160 and assessing the impact, if any, they may have on our financial position 
and results of operations.

SFAS  157—Statement  of  Financial  Accounting  Standards  No. 157,  “Fair  Value  Measurements”  (“SFAS 157”), 
establishes a single authoritative definition of fair value based upon the assumptions market participants would use 
when pricing an asset or liability and creates a fair value hierarchy that prioritizes the information used to develop 
those  assumptions.  Under  the  standard,  additional  disclosures  are  required,  including  disclosures  of  fair  value 
measurements  by  level  within  the  fair  value  hierarchy.  SFAS  157  is  effective  for  fair  value  measures  already 
required  or  permitted  by  other  standards  for  fiscal  years  beginning  after  November 15,  2007  and  interim  periods 
within those fiscal years. For non-financial assets and liabilities, the adoption of SFAS No. 157 has been deferred 
until  January  1,  2009.  We  are  adopting  SFAS  157  as  of  January  1,  2008  and  are  currently  in  the  process  of 
determining the effects of adoption, such as the effect of incorporating our own credit standing in the measurement 
of  certain  liabilities. We  do  not  expect  that  the  final  effects  of  adoption  will  have  a  significant  impact  on  our 
consolidated financial statements. 

SFAS 159—In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and 
Financial Liabilities” (“SFAS 159”). SFAS 159 provides companies with an option to report selected financial assets 
and liabilities at fair value. SFAS 159 is effective as of the beginning of an entity’s first fiscal year beginning after 
November 15, 2007. We adopted SFAS 159 as of January 1, 2008. Adoption 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. 

FSP FIN 39-1—In April 2007,  the FASB  issued  FSP FIN 39-1,  “An Amendment  of FASB Interpretation No. 39” 
(“FSP  FIN  39-1”).  FSP  FIN  39-1  allows  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 must arise from derivative instruments recognized at fair value that are executed 
with  the  same  counterparty  under  a  master  netting  arrangement.  A  company  must  make  an  accounting  policy 
decision  whether  or  not  to  offset  fair  value  amounts.  FSP  FIN  39-1  is  effective  for  fiscal  years  beginning  after 
November 15, 2007 and is to be applied retrospectively. We are currently evaluating the provisions of FSP FIN 39-1 
and assessing the impact it may have on our financial position and results of operations.

Supplemental Oil and Gas Information (Unaudited) 

In  accordance  with  SFAS  No. 69,  “Disclosures  about  Oil  and  Gas  Producing  Activities”  (“SFAS  69”),  and 
regulations of the SEC, we are making the following supplemental disclosures about our crude oil and natural gas 
exploration and production operations. 

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. 

Engineers in our Houston, Denver and London offices prepare all reserve estimates for our different geographical 
regions. These reserve estimates are reviewed and approved by senior engineering staff and division management 
with final approval by the Director of Asset Development and certain members of senior management. During each 
of the years 2007, 2006 and 2005, we retained Netherland, Sewell & Associates, Inc. (“NSAI”), independent third-
party reserve engineers, to perform reserve audits of proved reserves. The reserve audit for 2007 included a detailed 
review  of  16  of  our  major  international,  deepwater  Gulf  of  Mexico  and  US  fields,  which  covered  approximately 
71% of US proved reserves and 96% of international proved reserves (81% of total proved reserves). The reserve 
audit for 2006 included a detailed review of 14 of our major international, deepwater Gulf of Mexico and US fields, 
which  covered  approximately  80%  of  our  total  proved  reserves.  The  reserve  audit  for  2005  included  a  detailed 
review  of  11  of  our  major  international,  deepwater  Gulf  of  Mexico  and  US  fields,  which  covered  approximately 
72% of our total proved reserves. See Items 1 and 2. Business and Properties—Proved Reserves. 

Results  of  drilling,  testing  and  production  subsequent  to  the  date  of  the  estimate  may  justify  revision  of  such 
estimate. Accordingly, reserve estimates are often different from the quantities of crude oil and natural gas that are 
ultimately recovered. 

Our supplemental disclosures are grouped by geographic area and include the United States, West Africa (Equatorial 
Guinea  and  Cameroon),  Israel,  Ecuador,  North  Sea  and  Other  International  (Argentina,  China  and  Suriname). 
Operations  in  Equatorial  Guinea,  Cameroon,  Ecuador,  China  and  Suriname  are  conducted  in  accordance  with  the 
terms of production sharing contracts. 

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

Reserve 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. 

Reserve Audit. The process involving an independent third-party engineering firm’s visits, collection of any and all 
required  geologic,  geophysical,  engineering  and  economic  data,  and  such  firm’s  complete  external  preparation  of 
reserve estimates. 

The following definitions apply to our categories of proved reserves: 

Proved Reserves. Proved oil and gas reserves are the estimated quantities of crude oil, natural gas and natural gas 
liquids  which  geological  and  engineering  data  demonstrate  with  reasonable  certainty  to  be  recoverable  in  future 
years from known reservoirs under existing economic and operating conditions (i.e., prices and costs as of the date 
the  estimate  is  made).  Prices  include  consideration  of  changes  in  existing  prices  provided  only  by  contractual 
arrangements, but not on escalations based upon future conditions. 

Proved  Developed  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. 

94 

 
Proved  Undeveloped  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 Regulation S-X, 
Rule 4-10(a)(2), (3) and (4). 

Proved Gas Reserves (Unaudited)

2007. We expect the sale, which is subject to regulatory and partner approvals, to close in 2008. 
Increases for Ecuador are due to better than expected performance.

(3)  The increase in US proved reserves includes 57 Bcf in the Wattenberg field and 40 Bcf in the Mid-continent area, primarily 

due to infill drilling activities. 
Purchase of minerals in place is the result of the Patina Merger. See Note 3—Acquisitions and Divestitures. 
Increases for Ecuador and North Sea are due to better than expected performance. 

(4) 
(5) 
(6)  The increase in US proved reserves includes 140 Bcf in the Wattenberg field, 77 Bcf in the Piceance basin and 55 Bcf in the 

(7) 

(8) 

Mid-continent area, primarily due to infill drilling activities. 
Purchase of minerals in place includes 128 Bcf acquired in the purchase of U.S. Exploration. See Note 3—Acquisitions and 
Divestitures. 
Sale  of  minerals  in  place  is  primarily  due  to  sale  of  Gulf  of  Mexico  shelf  properties.  See  Note  3—Acquisitions  and 
Divestitures. 

(9)  The negative revisions within the US are primarily due to 103 Bcf of natural gas being reflected in the proved oil reserve 
table as NGLs, partially offset by positive revisions resulting from an increase in commodity price.  West Africa’s positive 
revisions  are  primarily  due  to  additional  production  allowances  related  to  LNG  sales.    Positive  revisions  in  Ecuador  are 
related to better than expected well performance. 

(10)  The 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.

(1)  Other  International  includes  China  and  Argentina.  We  have  entered  into  an  agreement  to  sell  our  interest  in  Argentina 
effective July 1, 2007. We expect the sale, which is subject to regulatory and partner approvals, to close in 2008. Argentina 
crude oil reserves totaled 6,759 MBbls at December 31, 2007. 

(2)  The  increase  in  total  proved  reserves  includes  6  MMBbl  in  the  US  Wattenberg  field,  primarily  due  to  infill  drilling 
activities, 3 MMBbl in the deepwater Gulf of Mexico Lorien field and 13 MMBbl in the North Sea Dumbarton field.  
Purchase of minerals in place is the result of the Patina Merger. See Note 3—Acquisitions and Divestitures. 

(3) 
(4)  The increase in US proved reserves includes 14 MMBbl in the Wattenberg field, primarily due to infill drilling activities. 
(5) 

Purchase of minerals in place includes 18 MMBbl acquired in the purchase of U.S. Exploration. See Note 3—Acquisitions 
and Divestitures. 
Sale  of  minerals  in  place  is  primarily  due  to  the  sale  of  Gulf  of  Mexico  shelf  properties.  See  Note  3—Acquisitions  and 
Divestitures. 

(7)  The positive revisions within the US are primarily due to 29 MMBls 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.   

(8)  The increase in proved reserves includes 17 MMBbl in the US Wattenberg field, primarily due to infill drilling activities, 8 

(6) 

MMBbl in the deepwater Gulf of Mexico and 10 MMBbl in the North Sea Dumbarton field area. 

(9)  West Africa production includes sales from the Alba field to the Alba LPG plant of 2,805 MBbls in 2007, 2,931 MBbls in 

2006 and 1,183 MBbls in 2005.

(1)  Other  International  includes  China  and  Argentina.  We  have  entered  into  an  agreement  to  sell  our  interest  in  Argentina 
effective  July  1,  2007.  We  expect  the  sale,  which  is  subject  to  regulatory  and  partner  approvals,  to  close  in  2008. 
Argentina’s standardized measure of discounted future net cash flows totaled $66 million at December 31, 2007.

Future cash inflows are computed by applying year-end prices, adjusted for location and quality differentials on a 
property-by-property  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 China and Argentina. 

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  year-end  prices  at  December 31,  2007  would  change  the  discounted  future  net  cash 
flows before income taxes by approximately $176 million or $154 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 
$671 million in 2008, $715 million in 2009 and $408 million in 2010. 

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 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  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 effective. 

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 

During  the  fourth  quarter  of 2007,  we  implemented  the  first  phase of  a  new  Enterprise  Resource  Planning  (ERP) 
software system to replace our various legacy systems.  As appropriate, we modified the design and documentation 
of internal control processes and procedures relating to the new system.  We believe that the new ERP system has 
strengthened and will continue to fortify our internal controls over financial reporting as additional phases are put to 
use; however, there are inherent risks in implementing any new system that could impact our financial reporting. See 
Item  1A.  Risk  Factors—Information  technology  systems  implementation  issues  could  disrupt  our  internal 
operations, increase our costs and adversely affect our financial results or our ability to report our financial results.  

In the event that issues arise, we have manual procedures in place which would facilitate our continued recording 
and  reporting  of  results  from  the  new  ERP  system.  However,  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. 

We will continue to monitor, test, and appraise the impact and effect of the new ERP system on our internal controls 
and procedures as additional phases and features of the system are implemented. 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, except as described above.
