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. 19316easD2R3.p5.ps 3/7/08 9:54 AM Page 5 In October 2007, Standard & Poor’s added Noble Energy to the S&P 500, a group of leading companies in numerous U.S. industries. 19316easD2R2.qxp 3/5/08 8:06 PM Page 6 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. 19316easD2R2.qxp 3/5/08 8:06 PM Page 7 L E T T E R T O S H A R E H O L D E R S 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). 19316easD2R2.qxp 3/5/08 8:06 PM Page 8 2007 SALES VOLUMES Rocky Mountains 26% Deepwater U.S. 12% Other U.S. 17% West Africa 23% North Sea/Israel 16% Other International 6% 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 19316easD2R2.qxp 3/5/08 8:06 PM Page 9 - 2007 RESERVES U.S. Liquids 23% U.S. Gas 35% International Liquids 14% International Gas 28% 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. 19316easD2R3.p10.ps 3/7/08 7:39 AM Page 10 ANNUAL NET INCOME (in millions) ANNUAL SALES VOLUMES (MMBoe) 1000 800 600 400 200 0 80 70 60 50 40 30 20 10 0 03 04 05 06 07 03 04 05 06 07 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. CHARLES D.

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. 1 Proved reserves estimates at December 31, 2007 were as follows: United States Natural gas (Bcf) Crude oil (MMBbls) Total US (MMBoe) International Natural gas (Bcf) Crude oil (MMBbls) Total International (MMBoe) Worldwide Natural gas (Bcf) Crude oil (MMBbls) Total Worldwide (MMBoe) Proved Developed Reserves December 31, 2007 Proved Undeveloped Reserves Total Proved Reserves 1,259 129 339 1,297 100 316 2,556 229 655 581 78 175 170 22 50 751 100 225 1,840 207 514 1,467 122 366 3,307 329 880 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 2 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. 3 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: Year Ended December 31, 2007 Sales Volumes Natural Gas Crude Oil (MBbls) (MMcf) Total (MBoe) Natural Gas (Bcf) December 31, 2007 Proved Reserves Crude Oil (MMBbls) Total (MMBoe) Northern Region Wattenberg Piceance Niobrara Other Total Southern Region Deepwater Gulf of Mexico Mid-continent Gulf Coast onshore and other Total Total United States 59,670 7,797 7,897 9,392 84,756 18,722 30,760 16,219 65,701 150,457 4,674 7 - 53 4,734 5,847 3,340 1,530 10,717 15,451 14,619 1,307 1,316 1,618 18,860 8,967 8,467 4,233 21,667 40,527 893 183 98 139 1,313 79 341 107 527 1,840 109 - - 1 110 21 51 25 97 207 258 31 16 24 329 34 108 43 185 514 4 Additional information for our significant US operating areas is as follows: Northern Region Wattenberg Piceance Niobrara Other Total Southern Region Deepwater Gulf of Mexico Mid-continent Gulf Coast onshore and other Total Total United States Year Ended December 31, 2007 Gross Wells Drilled/ Participated in December 31, 2007 Gross Productive Wells 508 55 125 56 744 6 147 38 191 935 5,161 112 744 1,239 7,256 13 3,981 457 4,451 11,707 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 5 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. 7 Additional information for our significant international operating areas is as follows: Year Ended December 31, 2007 Sales Volumes Natural Gas Crude Oil (MBbls) (MMcf) Total (MBoe) Natural Gas (Bcf) December 31, 2007 Proved Reserves Crude Oil (MMBbls) Total (MMBoe) International West Africa North Sea Israel Ecuador China Argentina Total consolidated Equity investees: Condensate (MBbls) LPG (MBbls) Total Equity investee share of methanol sales (Kgal) 48,349 2,276 40,449 9,385 - - 100,459 - - 100,459 5,500 4,564 - - 1,402 1,034 12,500 670 2,135 15,305 13,558 4,943 6,742 1,564 1,402 1,034 29,243 670 2,135 32,048 160,540 941 19 319 188 - - 1,467 82 25 - - 8 7 122 239 28 53 31 8 7 366 Wells drilled in 2007 and productive wells at December 31, 2007 in our international operating areas were as follows: International West Africa North Sea Israel Ecuador China Argentina Total International Year Ended December 31, 2007 Gross Wells Drilled/Participated in December 31, 2007 Gross Productive Wells 7 2 1 - - 50 60 20 22 8 5 16 732 803 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. 8 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. 10 Sales Volumes, Price and Cost Data—Sales volumes, price and cost data are as follows: Sales Volumes (1) Average Sales Price Production Cost Average Natural Gas Crude Oil Natural Gas Crude Oil Per Bbl (2) Per Mcf (2) MBbls MMcf Per BOE (3) Year Ended December 31, 2007 United States West Africa (4) (5) North Sea Israel Other International (6) Total Consolidated Operations Equity Investee (7) Total Year Ended December 31, 2006 United States West Africa (4) (5) North Sea Israel Other International (6) Total Consolidated Operations Equity Investee (7) Total Year Ended December 31, 2005 United States West Africa (4) (5) North Sea Israel Other International (6) Total Consolidated Operations Equity Investee (7) Total 150,457 15,451 $ 7.51 $ 53.22 $ 8.49 48,349 2,276 40,449 9,385 250,916 - 250,916 5,500 4,564 - 2,436 27,951 2,805 30,756 0.29 6.54 2.79 - 5.26 71.27 76.47 - 53.69 60.61 - 5.26 $ 55.09 60.10 $ 2.89 9.81 1.14 12.06 6.99 164,875 16,715 $ 6.61 $ 50.68 $ 8.12 16,579 2,967 33,906 9,041 227,368 - 227,368 6,519 1,357 - 2,752 27,343 2,931 30,274 0.37 8.00 2.72 0.96 5.55 62.51 67.43 - 52.05 54.47 - 5.55 $ 45.83 53.64 $ 2.86 10.08 1.60 9.74 6.97 125,543 9,468 $ 7.43 $ 46.67 $ 7.39 23,938 3,394 24,228 8,389 185,492 - 185,492 6,492 1,964 - 2,866 20,790 1,183 21,973 0.25 5.93 2.68 1.10 5.78 42.51 52.68 - 42.37 45.35 - 5.78 $ 43.43 45.25 $ 2.93 7.54 2.11 7.15 6.06 (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 11 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 December 31, 2007 is as follows: United States - Onshore United States - Offshore West Africa North Sea Israel Ecuador China Argentina Total Crude Oil Wells Net Gross Natural Gas Wells Net Gross Total Gross Net 7,055 28 1 15 - - 16 732 7,847 5,997.8 26.1 0.4 2.7 - - 9.1 95.4 6,131.5 4,609 15 19 7 8 5 - - 4,663 3,134.5 8.1 7.2 0.7 3.8 5.0 - - 3,159.3 11,664 43 20 22 8 5 16 732 12,510 9,132.3 34.2 7.6 3.4 3.8 5.0 9.1 95.4 9,290.8 Multiple Completions 8 5.9 14 3.6 22 9.5 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. 12 Developed and Undeveloped Acreage—Developed and undeveloped acreage (including both leases and concessions) held at December 31, 2007 was as follows: United States Onshore Offshore Total United States Equatorial Guinea Cameroon North Sea (1) Israel China Ecuador Argentina Suriname Total International Total Worldwide (2) Developed Acreage Net Gross Undeveloped Acreage Gross Net 1,308,823 147,945 1,456,768 45,203 - 48,230 123,552 7,413 12,355 113,325 - 350,078 1,806,846 835,445 94,963 930,408 15,727 - 5,671 58,142 4,225 12,355 15,548 - 111,668 1,042,076 1,234,858 485,258 1,720,116 850,197 1,125,000 836,625 1,183,479 - 851,771 - 7,740,328 12,587,400 14,307,516 786,391 227,627 1,014,018 379,026 562,500 339,151 532,818 - 851,771 - 6,362,884 9,028,150 10,042,168 (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. 13 Drilling Activity—The results of crude oil and natural gas wells drilled and completed for each of the last three years were as follows: Net Exploratory Wells Net Development Wells Productive Dry Total Productive (1) Dry Total Year Ended December 31, 2007 United States West Africa North Sea Israel Argentina Total Year Ended December 31, 2006 United States West Africa North Sea Argentina Total Year Ended December 31, 2005 United States West Africa North Sea Argentina Total 14.2 2.6 0.5 - - 17.3 6.3 - - - 6.3 4.7 - - - 4.7 4.5 0.5 - - 0.1 5.1 9.0 0.4 - - 9.4 10.7 - 0.2 - 10.9 18.7 3.1 0.5 - 0.1 22.4 15.3 0.4 - - 15.7 15.4 - 0.2 - 15.6 757.6 - - 0.4 6.7 764.7 666.6 1.8 1.1 7.6 677.1 488.1 0.3 - 7.7 496.1 27.6 - - - - 27.6 5.5 - - - 5.5 25.9 - - - 25.9 785.2 - - 0.4 6.7 792.3 672.1 1.8 1.1 7.6 682.6 514.0 0.3 - 7.7 522.0 (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. 14 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. 15 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.

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; • our future results of operations; • our liquidity and ability to finance our acquisition, exploration and development activities; • market conditions in the oil and gas industry; • our ability to make and integrate acquisitions; and • the impact of governmental regulation. Forward-looking statements are typically identified by use of terms such as “may,” “will,” “expect,” “anticipate,” “estimate” and similar words, although some forward-looking statements may be expressed differently. These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements. You should consider carefully the statements under Item 1A. Risk Factors and other sections of this report, which describe factors that could cause our actual results to differ from those set forth in the forward-looking statements. Item 1B. Unresolved Staff Comments. None. 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.

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. 31 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.

Financial Statements and Supplementary Data—Note 16—Recently Issued Pronouncements. 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. Cash Flows Summary cash flow information is as follows: Total cash provided by (used in): Operating activities Investing activities Financing activities Increase (decrease) in cash and cash equivalents 2007 Year Ended December 31, 2006 (in thousands) 2005 $ 2,016,573 (1,403,089) (107,029) 506,455 $ $ 1,730,306 (1,098,339) (588,880) 43,087 $ $ 1,239,878 (1,892,488) 583,137 (69,473) $ 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. 35 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. Acquisition, Capital and Other Exploration Expenditures Expenditure information (on an accrual basis) is as follows: 2007 Year Ended December 31, 2006 (in thousands) 2005 Acquisition, Capital and Other Exploration Expenditures Lease acquisition of unproved property Exploration expenditures Development expenditures Corporate and other expenditures Total consolidated capital expenditures Our share of equity investee development costs Total $ 145,326 371,758 1,185,385 36,361 1,738,830 516 1,739,346 $ $ 53,652 203,035 1,054,780 35,069 1,346,536 580 1,347,116 $ $ 16,793 161,515 662,585 21,478 862,371 27,639 890,010 $ 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. Insurance Recoveries See Item 8. Financial Statements and Supplementary Data—Note 4—Effect of Gulf Coast Hurricanes. 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 36 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. 37 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. Contractual Obligations The following table summarizes certain contractual obligations that are reflected in the consolidated balance sheets and/or disclosed in the accompanying notes. See Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements. Total 2008 Payments Due by Period 2009 and 2010 (in thousands) 2011 and 2012 2013 and Beyond Long-term debt (excludes interest) (1) Drilling and equipment obligations (2) : United States drilling and equipment International drilling and equipment Purchase obligations (3) Throughput agreement (4) Operating lease obligations (5) : Office buildings and facilities Oil and gas operations equipment Other long-term liabilities (6) : Asset retirement obligations (7) Derivative instruments (8) Total contractual obligations $ 1,880,000 $ 25,000 $ 25,000 $ 1,180,000 $ 650,000 462,759 68,170 194,419 95,000 52,894 12,074 181,337 68,170 194,419 - 173,935 - - 38,000 7,289 5,467 14,495 6,607 107,487 - - 38,000 13,247 - - - - 19,000 17,863 - 144,288 603,133 3,512,737 $ 13,332 525,159 1,020,173 $ 12,443 77,974 348,454 $ 13,034 - 1,351,768 $ 105,479 - 792,342 $ (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. (4) 38 (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. Natural Gas Information 2007 Year Ended December 31, 2006 (in thousands) 2005 Natural gas sales $ 1,271,866 $ 1,211,782 $ 1,023,644 Average daily natural gas sales volumes and average realized sales prices were as follows: 2007 Year Ended December 31, 2006 2005 Mcfpd $/Mcf Mcfpd $/Mcf Mcfpd $/Mcf North America (1) West Africa (2) North Sea Israel Ecuador (3) Other International 412,212 132,464 6,235 110,820 25,713 - $ 7.51 451,712 $ 6.61 343,953 $ 7.43 0.29 6.54 2.79 - - 45,422 8,130 92,894 24,475 294 0.37 8.00 2.72 - 0.96 65,581 9,299 66,377 22,795 190 0.25 5.93 2.68 - 1.10 Total 687,444 $ 5.26 622,927 $ 5.55 508,195 $ 5.78 (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. 40 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. Crude Oil Information 2007 Year Ended December 31, 2006 (in thousands) 2005 Crude oil sales $ 1,694,233 $ 1,489,459 $ 942,778 Average daily crude oil sales volumes and average realized sales prices were as follows: 2007 Year Ended December 31, 2006 Production (1) Bopd Sales Bopd $/Bbl Production (1) Bopd Sales 2005 Sales (2) Bopd $/Bbl Bopd $/Bbl United States (3) West Africa (4) North Sea Other International (5) Total Consolidated Operations Equity Investees (6) Total 42,332 15,523 12,813 6,806 77,474 8,014 85,488 42,332 15,070 12,505 6,674 76,581 7,684 84,265 53.22 71.27 76.47 53.69 60.61 55.09 60.10 45,798 17,326 3,988 7,491 74,603 7,531 82,134 45,798 17,860 3,717 7,540 74,915 8,032 82,947 50.68 62.51 67.43 52.05 54.47 45.83 53.64 25,941 17,786 5,380 7,851 56,958 3,240 60,198 46.67 42.51 52.68 42.37 45.35 43.43 45.25 $ $ $ $ $ $ 41 (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. 42 Income from Equity Method Investees We own a 45% interest in AMPCO, which owns and operates a methanol plant and related facilities and a 28% interest in Alba Plant, which owns and operates an LPG processing plant. The plants and related facilities are located in Equatorial Guinea. We account for investments in entities that we do not control but over which we exert significant influence using the equity method of accounting. Our share of operations of equity method investees was as follows: Net income (in thousands): AMPCO and affiliates Alba Plant Distributions/dividends (in thousands): AMPCO and affiliates Alba Plant Sales volumes (1): Methanol (Kgal) Condensate (Bopd) LPG (Bpd) Production volumes (1): Condensate (Bopd) LPG (Bpd) Average realized prices: Methanol (per gallon) Condensate (per Bbl) LPG (per Bbl) Year Ended December 31, 2006 2005 2007 $ 82,877 128,051 $ 38,024 101,338 $ 56,896 33,916 96,483 132,251 37,350 155,158 59,625 - 160,540 1,836 5,848 109,942 1,738 6,294 162,446 912 2,328 1,860 6,154 1,730 5,801 912 2,328 $ 1.09 74.87 48.87 $ 0.90 66.60 40.10 $ 0.77 55.76 38.63 (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. 43 Costs and Expenses Production Costs—Production costs were as follows: Total United States West North Africa Sea (in thousands) Israel Other Int'l/ Corporate (2) Year Ended December 31, 2007 Oil and gas operating costs (1) Workover and repair expense Lease operating expense Production and ad valorem taxes Transportation expense Total production costs Year Ended December 31, 2006 Oil and gas operating costs (1) Workover and repair expense Lease operating expense Production and ad valorem taxes Transportation expense Total production costs Year Ended December 31, 2005 Oil and gas operating costs (1) Workover and repair expense Lease operating expense Production and ad valorem taxes Transportation expense Total production costs $ 299,622 22,830 322,452 113,547 51,699 487,698 $ 190,723 22,516 213,239 91,225 39,542 344,006 $ $ $ $ 270,136 46,951 317,087 108,979 28,542 454,608 $ $ $ $ 205,348 46,793 252,141 85,960 20,728 358,829 203,833 14,027 217,860 78,703 16,764 313,327 $ 136,087 13,734 149,821 65,428 9,350 224,599 $ $ $ $ $ $ $ $ $ 39,222 - 39,222 - - 39,222 26,557 - 26,557 - - 26,557 30,661 - 30,661 - - 30,661 $ $ $ $ 37,987 - 37,987 - 10,523 48,510 11,655 - 11,655 - 7,010 18,665 12,244 259 12,503 - 6,562 19,065 $ $ $ $ 7,712 - 7,712 - - 7,712 9,066 - 9,066 - - 9,066 8,504 - 8,504 - - 8,504 $ $ $ $ 23,978 314 24,292 22,322 1,634 48,248 17,510 158 17,668 23,019 804 41,491 16,337 34 16,371 13,275 852 30,498 $ $ $ $ (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. 44 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: Oil and gas operating costs Workover and repair expense Lease operating costs Production and ad valorem taxes Transportation expense Total production costs (1) (2) 2007 $ Year Ended December 31, 2006 $ 2005 $ 4.29 0.33 4.62 1.63 0.74 4.14 0.72 4.86 1.67 0.44 3.94 0.27 4.21 1.52 0.33 $ 6.99 $ 6.97 $ 6.06 (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. 45 Oil and Gas Exploration Expense—Exploration expense was as follows: Total United States West Africa North Sea Other Int'l/ Corporate (1) Israel (in thousands) Year Ended December 31, 2007 Dry hole expense Unproved lease amortization Seismic Staff expense Other Total exploration expense Year Ended December 31, 2006 Dry hole expense Unproved lease amortization Seismic Staff expense Other Total exploration expense Year Ended December 31, 2005 Dry hole expense Unproved lease amortization Seismic Staff expense Other Total exploration expense $ $ $ 90,210 16,013 64,856 45,030 2,973 219,082 70,325 18,836 37,676 38,861 2,226 167,924 98,015 17,855 21,761 34,945 5,850 178,426 $ $ 49,473 15,176 55,258 11,900 2,423 134,230 $ $ $ 40,399 - 939 2,106 100 43,544 5 $ 103 8,184 8,318 340 16,950 $ $ $ $ $ $ 66,150 18,823 29,320 12,710 1,083 128,086 95,678 17,855 11,631 16,255 4,974 146,393 $ $ 46 - 4,204 2,887 192 7,329 1,403 - 316 3,760 (16) 5,463 $ $ 4,129 13 685 4,816 879 10,522 932 - 1,544 2,690 819 5,985 - $ - 691 645 82 1,418 $ - $ - 3 250 33 286 $ 2 $ - - 189 32 223 $ $ 333 734 (216) 22,061 28 22,940 $ - $ - 3,464 18,198 39 21,701 $ - $ - 8,270 12,051 41 20,362 $ $ $ $ $ (1) Other international includes Ecuador, China, Argentina and Suriname. 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. 46 Depreciation, Depletion and Amortization Expense—DD&A expense was as follows: United States West Africa North Sea Israel Other international, corporate, and other Total DD&A expense Unit rate of DD&A per BOE (1) (2) 2007 Year Ended December 31, 2006 (in thousands) $ 543,431 23,620 8,123 13,947 33,487 622,608 $ 574,001 25,315 79,450 17,842 31,373 727,981 $ $ 2005 $ 311,153 27,121 9,888 11,188 31,194 390,544 $ $ 10.43 $ 9.54 $ 7.55 (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. General and Administrative Expense—General and administrative (“G&A”) expense was as follows: Year Ended December 31, 2006 2005 2007 General and administrative expense (in thousands) Unit rate per BOE (1) (2) $ 206,378 $ 164,541 $ 100,125 $ 2.96 $ 2.52 $ 1.94 (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 $0.21 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. 47 Interest Expense and Capitalized Interest—Interest expense and capitalized interest were as follows: Interest expense, net Capitalized interest 2007 $ 112,957 16,595 Year Ended December 31, 2006 (in thousands) $ 117,045 12,515 2005 $ 87,541 8,684 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. (Gain) Loss on Derivative Instruments—See Item 8.

Financial Statements and Supplementary Data—Note 3—Acquisitions and Divestitures. Loss on Involuntary Conversion—See Item 8. Financial Statements and Supplementary Data—Note 4—Effect of Gulf Coast Hurricanes. Electricity Sales—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 fuel to the Machala power plant. Electricity sales are included in other revenues and electricity generation expense is included in other expense, net in the consolidated statements of operations. Operating data is as follows: Electricity sales (in thousands) Electricity generation expense (in thousands) Operating income (in thousands) Power generation (MW) Average power price ($/Kwh) Year Ended December 31, 2006 2005 2007 $ 70,916 56,552 14,364 911,830 $ 0.078 $ 71,603 59,494 12,109 865,983 $ 0.083 $ 74,228 53,137 21,091 799,160 $ 0.093 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 48 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 as follows: Year Ended December 31, 2007 2006 (in thousands) 2005 GMP proceeds GMP expenses Gross margin $ $ $ 24,087 17,539 6,548 27,876 18,664 9,212 $ $ $ 55,261 28,067 27,194 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: Income tax provision (in thousands) Effective rate Year Ended December 31, 2006 2005 2007 $ 423,697 31.0% $ 417,789 38.1% $ 322,940 33.3% 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. 49 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. 50 Item 8. Financial Statements and Supplementary Data.

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. Noble Energy, Inc. 52 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. KPMG LLP Houston, Texas February 25, 2008 53 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.

(“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. 60 Changes in the allowance for doubtful accounts are as follows: 2007 Year Ended December 31, 2006 (in thousands) 2005 Balance at beginning of period Charged to expense Deductions and other Balance at end of period $ $ $ 34,535 14,183 1,089 49,807 18,644 19,404 (3,513) 34,535 13,093 14,688 (9,137) 18,644 $ $ $ 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. Balance Sheet Information—Additional balance sheet information is as follows: December 31, 2007 2006 (in thousands) $ $ $ $ $ $ $ $ 15,058 60,479 24,981 100,518 357,129 123,779 37,475 4,829 33,457 556,669 206,435 18,059 224,494 225,098 50,972 61,597 337,667 $ $ $ $ $ $ 35,242 46,973 44,809 127,024 373,372 116,314 46,500 2,862 28,984 568,032 219,885 15,507 235,392 173,253 58,491 42,976 274,720 $ $ Other Current Assets Derivative instruments Materials and supplies inventories Prepaid expenses and other Total Other Noncurrent Assets Equity method investments Mutual fund investments Probable insurance claims Derivative instruments Other assets Total Other Current Liabilities Accrued and other current liabilities Interest payable Total Other Noncurrent Liabilities Deferred compensation liabilities Accrued benefit costs Other noncurrent liabilities Total 62 Statement of Operations Information—Other revenues and other expense, net consist of the following: 2007 Year Ended December 31, 2006 (in thousands) 2005 Other Revenues Electricity sales Gathering, marketing and processing Total Other Expense, net Electricity generation (1) Gathering, marketing and processing Deferred compensation expense Impairment of operating assets Other Total (1) See Allowance for Doubtful Accounts above. $ $ 70,916 24,087 95,003 $ $ 71,603 27,876 99,479 $ $ 74,228 55,261 129,489 $ $ $ 56,552 17,539 33,526 3,661 (6,068) 105,210 59,494 18,664 15,936 8,525 30,933 133,552 $ $ $ 53,137 28,067 14,980 5,368 5,855 107,407 Supplementary Disclosures of Cash Flow Information—Additional cash flow information is as follows: Cash paid during the year for: Interest (net of amount capitalized) Income taxes paid, net Non-cash financing and investing activities: Issuance of notes for property interests Issuance of common stock and options and liabilities assumed in Patina Merger 2007 Year Ended December 31, 2006 (in thousands) 2005 $ 104,910 149,058 $ 105,769 115,398 $ 83,860 121,687 50,000 - - - - 3,783,306 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 follows: Year Ended December 31, 2007 2006 (in thousands) Balance at beginning of period Goodwill associated with acquisitions Goodwill associated with sale of Gulf of Mexico shelf properties Tax benefits on stock options exercised Balance at end of period $ $ 781,290 (15,091) - (5,703) 760,496 862,868 27,711 (100,000) (9,289) 781,290 $ $ In accordance with Emerging Issues Task Force (“EITF”) Abstract Issue No. 00-23, “Issues Related to the 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. 63 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: December 31, 2007 2006 Carrying Amount Fair Value Carrying Amount Fair Value (in thousands) Total debt, net of discount $ 1,876,087 $ 1,919,990 $ 1,800,810 $ 1,852,890 See Note 7—Debt. 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. 64 The calculation of basic and diluted EPS is as follows: Net income available to common shareholders Basic EPS Net income available to common shareholders Effect of dilutive stock options and restricted stock awards Adjusted net income and shares Diluted EPS 2007 Year Ended December 31, 2006 2005 Income Shares Income Shares Income Shares (in thousands, except per share amounts) 943,870 $ $ 5.52 171,078 $ $ 678,428 3.86 175,707 $ $ 645,720 4.20 153,773 $ 943,870 171,078 $ 678,428 175,707 $ 645,720 153,773 - 943,870 5.45 $ $ 2,266 173,344 - 678,428 3.79 $ $ 3,337 179,044 - 645,720 4.12 $ $ 2,986 156,759 Options, restricted stock and shares of our common stock held in a rabbi trust excluded from the EPS calculation above as they were antidilutive are as follows: Weighted Outstanding Awards and Shares Weighted Average Exercise Price (in thousands, except per share amounts) Year Ended December 31, 2007 Stock options Noble Energy common stock held in rabbi trust and shares of restricted stock Total excluded from diluted EPS calculation Year Ended December 31, 2006 Stock options Noble Energy common stock held in rabbi trust and shares of restricted stock Total excluded from diluted EPS calculation Year Ended December 31, 2005 Stock options Noble Energy common stock held in rabbi trust Total excluded from diluted EPS calculation 1,014 1,102 2,116 675 1,276 1,951 48 1,360 1,408 $ 52.41 - - $ 45.19 - - $ 41.47 - 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. 65 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. Revenues Net income Earnings per share: Basic Diluted Year Ended December 31, 2005 (in thousands, except per share amounts) $ 2,434,677 693,091 $ 4.03 3.98 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. 69 Note 5—Capitalized Exploratory Well Costs We capitalize exploratory well costs until a determination is made that the well has found proved reserves or is deemed noncommercial, in which case the well costs are immediately charged to exploration expense. Changes in capitalized exploratory well costs are as follows and exclude amounts that were capitalized and subsequently expensed in the same period: 2007 Year Ended December 31, 2006 (in thousands) 2005 Capitalized exploratory well costs, beginning of period Additions to capitalized exploratory well costs pending determination of proved reserves Reclassified to property, plant and equipment based on determination of proved reserves Capitalized exploratory well costs charged to expense $ 80,359 $ 35,228 $ 62,724 182,271 62,580 33,671 (7,143) (16,762) (52,138) (6,454) (687) (9,029) Capitalized exploratory well costs, end of period $ 249,033 $ 80,359 $ 35,228 The following table provides an aging of capitalized exploratory well costs (suspended well costs) based on the date the drilling was completed and the number of projects for which exploratory well costs have been capitalized for a period greater than one year since the completion of drilling: Capitalized exploratory well costs that have been capitalized for a period of one year or less Capitalized exploratory well costs that have been capitalized for a period greater than one year after completion of drilling Balance at end of period 2007 December 31, 2006 (in thousands) 2005 $ 187,101 $ 58,493 $ 35,228 61,932 21,866 - $ 249,033 $ 80,359 $ 35,228 Number of projects that have exploratory well costs that have been capitalized for a period greater than one year after completion of drilling 6 4 - The following table provides a further aging of those exploratory well costs that have been capitalized for a period greater than one year since the completion of drilling as of December 31, 2007: Project: Raton South (Deepwater Gulf of Mexico) Redrock (Deepwater Gulf of Mexico) Blocks O and I (West Africa) Other Total capitalized exploratory well costs that have been capitalized for a period greater than one year after completion of drilling Total Suspended Since 2005 2006 (in thousands) $ 23,374 17,133 19,039 2,386 $ 23,374 17,133 - 2,386 - $ - 19,039 - $ 61,932 $ 42,893 $ 19,039 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 70 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: Year Ended December 31, 2007 (in thousands) Asset retirement obligations, beginning of period Liabilities incurred in current period Liabilities settled in current period Revisions Accretion expense Asset retirement obligations, end of period Current portion Noncurrent portion $ 196,189 8,927 (176,961) 108,008 8,125 144,288 $ $ 13,332 130,956 Approximately $125 million of liabilities settled and $64 million of revisions related to hurricane damage to the Gulf of Mexico Main Pass assets. The remainder of the liabilities settled and revisions resulted primarily from changes in estimated timing of actual abandonment and overall cost increases for Gulf of Mexico assets. See Note 4—Effect of Gulf Coast Hurricanes. 71 Note 7—Debt Our debt consists of the following: $2.1 billion Credit Facility 5 ¼% Senior Notes, due April 2014 7 ¼% Notes, due October 2023 8% Senior Notes, due April 2027 7 ¼% Senior Debentures, due August 2097 Installment payments, due May 2009 Long-term debt Installment payments - current portion Total debt Unamortized discount Total debt, net of discount December 31, 2007 2006 Debt Interest Rate Debt Interest Rate (in thousands, except percentages) 5.28 5.25 7.25 8.00 7.25 5.53 5.53 $ 1,180,000 200,000 100,000 250,000 100,000 25,000 1,855,000 25,000 1,880,000 (3,913) $ 1,876,087 $ 1,155,000 200,000 100,000 250,000 100,000 - 1,805,000 - 1,805,000 (4,190) $ 1,800,810 5.69 5.25 7.25 8.00 7.25 - - 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 72 depending upon our credit rating. Interest was payable periodically based on the tenor of the underlying Eurodollar rate selected at the time of a rate reset. Annual Maturities—Annual maturities of outstanding debt are as follows: 2008 2009 2010 2011 2012 Thereafter Total (in thousands) $ 25,000 25,000 - - 1,180,000 650,000 1,880,000 $ Short-Term Borrowings—Our credit agreement is supplemented by short-term borrowings under various uncommitted credit lines used for working capital purposes. Uncommitted credit lines may be offered by certain banks from time to time at rates negotiated at the time of borrowing. Other than the installment payments discussed above, no short-term borrowings were outstanding at December 31, 2007 or 2006. Note 8—Income Taxes Components of income before income taxes are as follows: Domestic Foreign Total The income tax provision consists of the following: Current taxes: Federal State Foreign Total current Deferred taxes: Federal State Foreign Total deferred Total income tax provision 2007 2005 Year Ended December 31, 2006 (in thousands) $ $ 480,200 887,367 1,367,567 $ 402,111 694,106 1,096,217 $ $ 426,756 541,904 968,660 $ 2007 Year Ended December 31, 2006 (in thousands) 2005 $ 6,409 506 124,901 131,816 185,503 6,283 100,095 291,881 423,697 $ $ 79,680 5,577 138,271 223,528 144,143 4,641 45,477 194,261 417,789 $ $ 48,293 - 90,877 139,170 119,953 14,073 49,744 183,770 322,940 $ 73 A reconciliation of the federal statutory tax rate to the effective tax rate is as follows: Federal statutory rate Effect of: Earnings of equity method investees State taxes, net of federal benefit Difference between US and foreign rates Nondeductible goodwill AJCA repatriation benefit Other, net Effective rate Deferred tax assets and liabilities resulted from the following: 2007 Year Ended December 31, 2006 (amounts in percentages) 2005 35.0 (5.4) 0.5 1.6 - - (0.7) 31.0 35.0 (4.2) 1.3 2.2 3.1 - 0.7 38.1 35.0 (3.2) 1.3 3.5 - (3.7) 0.4 33.3 Deferred tax assets: Loss carryforwards Accrued expenses Allowance for doubtful accounts Fair value of derivative contracts Postretirement benefits Deferred compensation Foreign tax credits Other Total deferred tax assets Valuation allowance - foreign losses Valuation allowance - foreign tax credits Net deferred tax assets Deferred tax liabilities: Property, plant and equipment, principally due to differences in depreciation, amortization, lease impairment and abandonments Other Total deferred tax liability Net deferred tax liability December 31, 2007 2006 (in thousands) $ 20,571 26,227 3,566 176,750 10,233 60,993 82,037 14,037 394,414 (18,174) (56,619) 319,621 $ 90,387 34,083 2,917 185,667 14,578 55,880 63,707 3,577 450,796 (9,876) (63,708) 377,212 (2,183,950) 11,067 (2,172,883) (1,853,262) $ (2,034,877) (952) (2,035,829) (1,658,617) $ Net deferred tax liabilities were classified in the consolidated balance sheet as follows: December 31, 2007 2006 Deferred income tax asset Deferred income tax liability Net deferred tax liability (in thousands) 130,571 (1,983,833) (1,853,262) $ $ 99,835 (1,758,452) (1,658,617) $ $ 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 74 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. 75 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: 2007 Year Ended December 31, 2006 (in thousands) 2005 Stock-based compensation expense included in: General and administrative expense Exploration expense and other Total stock-based compensation expense $ $ $ $ 25,136 1,689 26,825 10,720 1,096 11,816 $ $ 4,008 - 4,008 Tax benefit recognized $ 10,086 $ 4,443 $ 1,403 Pro Forma Information—The following table illustrates the effect on net income and earnings per share if we had applied the fair value recognition provisions of SFAS 123(R) to stock-based employee compensation in all periods presented. The actual and pro forma net income and earnings per share for 2007 and 2006 below are the same since we adopted SFAS 123(R) as of January 1, 2006. The 2007 and 2006 amounts are presented for comparison to the prior year. Year Ended December 31, 2006 (actual) 2007 (actual) 2005 (pro forma) (unaudited) Net income, as reported Add: Stock-based compensation cost recognized, net of tax Deduct: Stock-based employee compensation expense determined under fair value based method for all awards, net of tax Pro forma net income Earnings per share: Basic - as reported Basic - pro forma Diluted - as reported Diluted - pro forma (in thousands, except per share amounts) $ 943,870 16,739 $ 678,428 7,373 $ 645,720 2,605 (16,739) 943,870 $ (7,373) 678,428 $ (6,150) 642,175 $ $ 5.52 5.52 5.45 5.45 $ 3.86 3.86 3.79 3.79 $ 4.20 4.18 4.12 4.10 Total stock-based compensation expense determined under the fair value based method for all awards for 2005 has been recalculated using revised expected term assumptions.

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: 2007 Year Ended December 31, 2006 (weighted averages) 2005 Expected term (in years) Expected volatility Risk-free rate Expected dividend yield Stock option activity was as follows: Outstanding at December 31, 2006 Granted Exercised Forfeited/Canceled Outstanding at December 31, 2007 Exercisable at December 31, 2007 5.5 29.6% 4.7% 0.6% 5.5 31.8% 4.7% 0.8% 5.5 21.5% 4.6% 0.4% Weighted Average Exercise Price (per share) $ 24.24 53.79 16.66 49.21 32.98 24.29 $ $ Options 6,211,750 1,557,919 (1,479,040) (115,568) 6,175,061 4,083,097 Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) 5.5 3.8 $ $ 287,768 225,499 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. 78 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: Number of simulations Expected volatility Risk-free rate Restricted stock activity was as follows: Year Ended December 31, 2006 2005 100,000 28.4% 4.4% 100,000 29.6% 3.3% Shares Subject to Service Conditions Weighted Average Grant Date Fair Value (per share) $ Outstanding at December 31, 2006 Granted Vested Forfeited Outstanding at December 31, 2007 73,095 547,818 (37,475) (15,848) 567,590 35.85 53.92 42.99 53.42 52.33 $ Shares Subject to Market Conditions 204,250 - (75,325) (4,788) 124,137 Weighted Average Grant Date Fair Value (per share) 29.27 $ - 22.23 40.51 33.11 $ 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. 79 Note 10—Additional Shareholders’ Equity Information Activity in shares of our common stock and treasury stock was as follows: Common stock shares issued Shares at beginning of period Exercise of common stock options Restricted stock awards, net of forfeitures Shares at end of period Treasury stock Shares at beginning of period Shares repurchased Rabbi trust shares sold Shares at end of period Year Ended December 31, 2006 2007 188,808,087 1,479,040 527,182 190,814,309 184,893,510 3,848,521 66,056 188,808,087 16,574,384 2,006,481 - 18,580,865 9,268,932 8,373,400 (1,067,948) 16,574,384 During 2007, we completed a $500 million common stock repurchase program begun in 2006.

Note 11—Benefit Plans Pension Plan and Other Postretirement Benefit Plans—We have a noncontributory, tax-qualified defined benefit pension plan covering employees who were hired prior to May 1, 2006. The benefits are based on an employee’s years of service and average earnings for the 60 consecutive calendar months of highest compensation. Our funding 80 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. 81 Changes in the benefit obligation and plan assets of the pension, restoration and other postretirement benefit plans are as follows at December 31: Retirement and Restoration Plan Medical and Life Plan 2006 2007 2006 (in thousands) Change in benefit obligation Benefit obligation at beginning of year Service cost Interest cost Plan participants' contributions Amendments Benefits paid Actuarial (gain) loss Benefit obligation at end of year Change in plan assets Fair value of plan assets at beginning of year Actual return on plan assets Employer contributions Plan participants' contributions Benefits paid Fair value of plan assets at end of year Funded status Funded status at end of year Net amount recognized in consolidated balance sheets (after adoption of FAS 158) Amounts recognized in consolidated balance sheets consist of: Current liabilities Noncurrent liabilities Net amount recognized in consolidated balance sheets (after adoption of FAS 158) Amounts not yet reflected in net periodic benefit cost and included in AOCL Transition obligation Prior service (cost) credit Accumulated loss AOCL Cumulative employer contributions in excess of net periodic benefit cost Net amount recognized in consolidated balance sheet (after adoption of FAS 158) Change in AOCL due to adoption of FAS 158 Additional minimum liability (before FAS 158) Intangible asset (before FAS 158) AOCL (before FAS 158) Net increase in AOCL 2007 $ 175,154 11,671 9,978 - 7,836 (6,513) (10,633) 187,493 136,890 12,982 11,395 - (6,513) 154,754 $ 168,301 11,781 9,550 - (8,327) (6,169) 18 175,154 94,832 12,593 35,634 - (6,169) 136,890 $ 22,373 1,962 1,191 332 - (830) (2,640) 22,388 $ 27,223 2,207 1,377 272 (5,711) (795) (2,200) 22,373 - - 498 332 (830) - - - 523 272 (795) - (32,739) (38,264) (22,388) (22,373) (32,739) (38,264) (22,388) (22,373) (2,958) (29,781) (32,739) (614) (2,981) (34,051) (37,646) 4,907 (1,205) (37,059) (1,197) (21,191) (941) (21,432) (38,264) (22,388) (22,373) (854) 5,372 (49,978) (45,460) - 5,746 (13,691) (7,945) - 6,672 (17,384) (10,712) 7,196 (14,443) (11,661) $ (32,739) (38,264) $ (22,388) (22,373) (2,708) 65 (2,643) (42,817) $ - - - (10,712) $ 82 Net periodic benefit cost recognized for the pension, restoration and other postretirement benefit plans is provided in the table below.

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% 2012 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 1% Increase 1% Decrease (in thousands) $ 390 2,270 $ (341) (2,025) 84 Weighted-average asset allocations for the tax-qualified defined benefit pension plan are as follows: Asset Category Equity Securities Fixed income Other Total Target Allocation 2008 70% 30% - 100% Plan Assets 2007 70% 30% - 100% 2006 70% 28% 2% 100% 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 Years 2013 to 2017 Retirement and Restoration Plan Medical and Life Plan (in thousands) $ 25,049 12,000 13,586 16,722 18,507 99,516 $ 1,197 1,370 1,499 1,914 2,198 14,280 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 85 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 Mutual fund investments Noble Energy common stock (at market value) Total rabbi trust assets Liability under Patina deferred compensation plan Number of shares of Noble Energy common stock held by rabbi trust December 31, 2007 2006 (in thousands) $ 106,581 87,554 194,135 $ 194,135 1,101,032 $ 100,767 54,027 154,794 $ 154,794 1,101,032 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 (Gain) loss on derivative instruments 2007 Year Ended December 31, 2006 (in thousands) $ $ (2,520) - 9,502 423,910 $ 930 51,750 2005 - (2,520) $ (41,045) 392,367 $ (20,000) 32,680 $ 86 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 2007 Year Ended December 31, 2006 (in thousands) (190,730) (41,698) (232,428) $ 2005 (140,486) (97,206) (237,692) $ (223,347) 169,242 (54,105) $ As of December 31, 2007, we had entered into, and designated as cash flow hedges, the following variable to fixed price swap derivative instruments related to natural gas and crude oil sales as follows: Production Period 2008 (NYMEX) 2008 (Brent) 2009 (NYMEX) 2009 (Brent) Natural Gas Crude Oil MMBtupd Average Price per MMBtu Bopd Average price per Bbl 170,000 $ 5.66 16,500 $ 38.23 - - - - - - 2,000 7,000 2,000 88.18 86.67 87.98 On January 2, 2008, we entered into additional NYMEX variable to fixed price swap derivative instruments for 1,000 Bpd of crude oil at an average price per Bbl of $90.50 for 2009. As of December 31, 2007, we had entered into the following basis swap derivative instruments related to natural gas sales. These basis swaps were combined with NYMEX variable to fixed swaps and designated as cash flow hedges: Production Period 2008 (CIG (1) vs. NYMEX) 2008 (ANR (2) vs. NYMEX) 2008 (PEPL (3) vs. NYMEX) (1) Colorado Interstate Gas – Northern System (2) ANR Oklahoma Pipeline (3) Panhandle Eastern Pipe Line Average Differential per MMBtu $ 1.66 1.01 0.98 MMBtupd 100,000 40,000 10,000 87 As of December 31, 2007, we had entered into, and designated as cash flow hedges, the following costless collar derivative instruments related to crude oil and natural sales as follows: Natural Gas Average Price per MMBtu Crude Oil Average Price per Bbl Production Period MMBtupd Floor Ceiling Bopd Floor Ceiling 2008 (NYMEX) 2008 (CIG) 2008 (Brent) 2009 (NYMEX) 2009 (CIG) 2009 (Brent) 2010 (NYMEX) 2010 (CIG) - 14,000 - - 15,000 - - 15,000 $ - 6.75 - - 6.00 - - 6.25 $ - 8.70 - - 9.90 - - 8.10 3,100 - 4,074 3,700 - 3,074 3,500 - $ 60.00 - 45.00 60.00 - 45.00 55.00 - $ 72.40 - 66.52 70.00 - 63.04 73.80 - 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 Current asset Long-term asset Current liability Long-term liability December 31, 2007 2006 (in thousands) $ 15,058 4,829 (540,217) (82,803) $ 35,242 2,862 (254,625) (328,875) 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 88 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. Equity method investments are as follows: December 31, 2007 2006 (in thousands) $ $ 199,605 142,540 14,984 357,129 $ 211,325 146,051 15,996 $ 373,372 Equity method investments AMPCO Alba Plant Other Total equity method investments 89 Summarized, 100% combined financial information for equity method investees is as follows: Balance sheet information Current assets Noncurrent assets Current liabilities Noncurrent liabilities Statements of operations information Operating revenues Less cost of goods sold Gross margin Less other expense Less income tax expense Net income Note 14—Commitments and Contingencies December 31, 2007 2006 (in thousands) $ 408,000 813,601 273,164 31,278 $ 252,201 857,465 171,028 2,385 2007 Year Ended December 31, 2006 (in thousands) 2005 $ $ $ 934,419 220,101 714,318 36,486 44,150 633,682 702,556 202,304 500,252 47,487 23,451 429,314 $ $ $ 464,000 136,508 327,492 35,798 67,142 224,552 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. 90 Minimum commitments as of December 31, 2007 consist of the following: $ $ $ $ Drilling and Equipment, and Purchase Obligations 443,926 94,444 79,491 65,715 41,772 - 725,348 Throughput Agreement $ - 19,000 19,000 19,000 19,000 19,000 $ 95,000 Office Buildings and Facilities (in thousands) Oil and Gas Operations Equipment Total 7,289 7,426 7,069 6,736 6,511 17,863 52,894 5,467 4,448 2,159 - - - 12,074 456,682 125,318 107,719 91,451 67,283 36,863 885,316 $ $ $ $ 2008 2009 2010 2011 2012 2013 and thereafter Total Note 15—Segment Information We have operations throughout the world and manage our operations by country.

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. 91 Year Ended December 31, 2007 Revenues from third parties Intersegment revenue Income from equity method investees Total Revenues DD&A Gain on derivative instruments Loss on involuntary conversion Income (loss) before taxes Investments in equity method investees Additions to long-lived assets Total assets at December 31, 2007 (1) Year Ended December 31, 2006 Revenues from third parties Intersegment revenue Income from equity method investees Total Revenues DD&A Loss on derivative instruments Income (loss) before taxes Investments in equity method investees Additions to long-lived assets Total assets at December 31, 2006 (1) Year Ended December 31, 2005 Revenues from third parties Intersegment revenue Income from equity method investees Total Revenues DD&A Loss on derivative instruments Loss on involuntary conversion Income (loss) before taxes Investments in equity method investees Additions to long-lived assets Total assets at December 31, 2005 (1) Total United States West Africa North Sea Israel (in thousands) Other Int'l, Corporate & Marketing $ 3,061,102 - 210,928 3,272,030 $ 1,609,626 342,809 - 1,952,435 $ 405,988 - 210,928 616,916 $ 727,981 (2,520) 51,406 1,367,567 357,129 990,861 574,001 (2,520) 51,406 809,806 357,129 877,941 25,315 - - 517,450 - 23,155 363,886 - - 363,886 79,450 - - 220,779 - 40,969 $ 113,001 - - 113,001 $ 568,601 (342,809) - 225,792 17,842 - - 86,022 - 24,716 31,373 - - (266,490) - 24,080 727,995 10,830,896 7,917,771 1,354,604 562,140 268,386 $ 2,800,720 - 139,362 2,940,082 $ 1,510,689 425,901 - 1,936,590 $ 413,682 - 139,362 553,044 $ 115,232 - - 115,232 $ 92,373 - - 92,373 $ 668,744 (425,901) - 242,843 622,608 392,367 1,096,217 373,372 1,916,139 9,588,625 543,431 392,367 631,087 - 1,615,435 7,224,920 23,620 - 493,777 373,372 35,121 960,357 $ 2,095,911 - 90,812 2,186,723 $ 913,564 460,808 - 1,374,372 $ 281,902 - 90,812 372,714 $ 390,544 32,680 1,000 968,660 311,153 32,680 1,000 585,988 420,362 4,382,005 8,878,033 - 4,345,604 6,577,853 27,121 - - 309,239 420,362 2,738 877,409 8,123 - 72,803 - 234,877 343,236 123,584 - - 123,584 9,888 - - 88,524 - 15,287 146,311 13,947 - 71,318 - 841 256,913 33,487 - (172,768) - 29,865 803,199 $ 65,050 - - 65,050 $ 711,811 (460,808) - 251,003 11,188 - - 46,468 - 5,928 266,312 31,194 - - (61,559) - 12,448 1,010,148 (1) The US reporting unit includes goodwill of $760 million at December 31, 2007, $781 million at December 31, 2006 and $863 million at December 31, 2005. 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. 92 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. 93 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) The following reserve schedule was developed by our reserve engineers and sets forth the changes in estimated quantities of proved natural gas reserves: United States West Africa Natural Gas and Casinghead Gas (MMcf) Israel Ecuador North Sea Other Int'l (1) Proved reserves as of: December 31, 2004 Revisions of previous estimates (2) Extensions, discoveries and other additions (3) Purchase of minerals in place (4) Sale of minerals in place Production December 31, 2005 Revisions of previous estimates (5) Extensions, discoveries and other additions (6) Purchase of minerals in place (7) Sale of minerals in place (8) Production December 31, 2006 Revisions of previous estimates (9) Extensions, discoveries and other additions (10) Purchase of minerals in place Sale of minerals in place Production December 31, 2007 Proved developed reserves as of: December 31, 2004 December 31, 2005 December 31, 2006 December 31, 2007 519,735 18,644 144,335 1,083,959 - (125,543) 1,641,130 (82,371) 314,140 141,610 (110,486) (164,830) 1,739,193 (67,003) 315,687 2,957 (1) (150,457) 1,840,376 917,409 7,732 - - - (23,938) 901,203 57,543 - 2,532 - (16,579) 944,699 44,256 - - - (48,349) 940,606 417,293 481 - - - (24,228) 393,546 260 - - - (33,906) 359,900 (52) - - - (40,449) 319,399 119,341 32,800 - - - (8,321) 143,820 32,927 - - - (8,933) 167,814 29,872 - - - (9,385) 188,301 430,513 1,278,788 1,255,271 1,259,331 447,347 431,142 359,691 830,191 360,428 336,681 303,035 262,534 119,341 143,820 167,814 188,301 11,714 3,200 - - - (3,394) 11,520 10,485 - - - (2,967) 19,038 (1,062) 3,086 - - (2,276) 18,786 11,714 11,520 19,038 15,700 Total 1,986,861 61,556 144,335 1,083,959 - (185,492) 3,091,219 19,122 314,140 144,142 (110,486) (227,323) 3,230,814 5,841 318,773 2,957 (1) (250,916) 3,307,468 1,369 (1,301) - - - (68) - 278 - - (108) 170 (170) - - - - - 1,118 - 170 - 1,370,461 2,201,951 2,105,019 2,556,057 (1) Other International includes Argentina.

Increases for Ecuador are due to better than expected performance. (2) (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. 95 Proved Oil Reserves (Unaudited) The following reserve schedule was developed by our reserve engineers and sets forth the changes in estimated quantities of proved crude oil reserves: Crude Oil, Condensate and NGLs (MBbls) North Sea Other Int'l (1) West Africa United States Proved reserves as of: December 31, 2004 Revisions of previous estimates Extensions, discoveries and other additions (2) Purchase of minerals in place (3) Sale of minerals in place Production (9) December 31, 2005 Revisions of previous estimates Extensions, discoveries and other additions (4) Purchase of minerals in place (5) Sale of minerals in place (6) Production (9) December 31, 2006 Revisions of previous estimates (7) Extensions, discoveries and other additions (8) Purchase of minerals in place Sale of minerals in place Production (9) December 31, 2007 Proved developed reserves as of: December 31, 2004 December 31, 2005 December 31, 2006 December 31, 2007 55,066 4,192 11,272 90,594 - (9,468) 151,656 (193) 23,037 19,328 (6,971) (16,715) 170,142 27,998 26,634 - (1,903) (15,451) 207,420 108,730 (120) - - - (7,675) 100,935 (1,327) - 138 - (9,450) 90,296 229 - - - (8,305) 82,220 32,390 114,223 114,505 128,879 108,730 100,935 90,296 71,409 9,336 278 12,955 - - (1,964) 20,605 (396) - - - (1,357) 18,852 776 10,094 - - (4,564) 25,158 9,336 7,650 18,852 15,064 Total 193,464 4,518 24,227 90,594 - (21,973) 290,830 (1,792) 24,831 19,466 (6,971) (30,274) 296,090 28,871 36,728 - (1,903) (30,756) 329,030 20,332 168 - - - (2,866) 17,634 124 1,794 - - (2,752) 16,800 (132) - - - (2,436) 14,232 18,040 15,623 15,936 13,688 168,496 238,431 239,589 229,040 (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. (2) The standardized measure of discounted future net cash flows for 2007, 2006 and 2005 does not include cash flows relating (3) to anticipated future methanol or power sales. Production costs include oil and gas operations expense, production and ad valorem taxes, transportation costs and general and administrative expense supporting oil and gas operations. 101 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: December 31, 2007 Average crude oil price per Bbl Average natural gas price per Mcf December 31, 2006 Average crude oil price per Bbl Average natural gas price per Mcf December 31, 2005 Average crude oil price per Bbl Average natural gas price per Mcf United States West Africa Israel Ecuador North Sea Other Int'l (1) Total $ 88.00 6.78 $ 81.26 0.27 $ - 2.69 $ - 3.74 $ 93.79 7.07 $ 61.72 - $ 85.62 4.36 $ 57.02 5.32 $ 51.49 0.27 $ - 2.70 $ - 3.75 $ 57.81 7.11 $ 48.04 0.85 $ 54.87 3.48 $ 58.20 8.59 $ 51.62 0.25 $ - 2.62 $ - 3.75 $ 58.47 5.39 $ 49.23 - $ 55.39 5.16 (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. Imbalance receivables and liabilities are as follows: Imbalance receivables Imbalance liabilities 2007 Year Ended December 31, 2006 (in thousands) 2005 $ 12,640 10,288 $ 18,389 16,750 $ 18,100 34,600 Imbalance receivables and imbalance liabilities have been excluded from the standardized measure of discounted future net cash flows. 102 Sources of Changes in Discounted Future Net Cash Flows (Unaudited) Principal changes in the aggregate standardized measure of discounted future net cash flows attributable to proved crude oil and natural gas reserves are as follows: 2007 Year Ended December 31, 2006 (in millions) 2005 Standardized measure of discounted future net cash flows at the beginning of the year Changes in standardized measure of dicounted future net cash flows: Sales of oil and gas produced, net of production costs Net changes in prices and production costs Extensions, discoveries and improved recovery, less related costs Changes in estimated future development costs Development costs incurred during the period Revisions of previous quantity estimates Purchases of minerals in place Sales of minerals in place Accretion of discount Net change in income taxes Change in timing of estimated future production and other Aggregate change in standardized measure of discounted future net cash flows Standardized measure of discounted future net cash flows at the end of the year $ 6,887 $ 8,771 $ 3,342 (2,427) 5,266 1,635 (775) 1,189 1,276 6 (95) 1,006 (1,900) (417) (2,177) (2,788) 769 (558) 1,076 (92) 573 (579) 1,274 777 (159) (1,563) 2,160 1,173 (912) 751 273 4,720 - 519 (2,099) 407 4,764 (1,884) 5,429 $ 11,651 $ 6,887 $ 8,771 103 Supplemental Quarterly Financial Information (Unaudited) Supplemental quarterly financial information is as follows: 2007 (1) Revenues Income before taxes Net income Earnings per share: Basic Diluted 2006 (2) Revenues Income before taxes Net income Earnings per share: Basic Diluted Quarter Ended March 31, June 30, September 30, December 31, Total (in thousands except per share amounts) $ 742,545 303,852 211,812 $ 794,213 293,101 209,105 $ 813,811 343,277 222,675 $ 921,461 427,337 300,278 $ 3,272,030 1,367,567 943,870 1.24 1.22 1.22 1.21 1.30 1.28 1.75 1.73 5.52 5.45 $ 711,997 349,353 226,087 $ 772,580 (44,865) (30,705) $ 741,319 544,966 318,064 $ 714,186 246,763 164,982 $ 2,940,082 1,096,217 678,428 1.28 1.26 (0.17) (0.17) 1.80 1.75 0.95 0.94 3.86 3.79 (1) First quarter 2007 includes a loss on involuntary conversion of $13 million and second quarter 2007 includes a loss on involuntary conversion of $38 million.

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. 104 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.
