ABOUT POGO PRODUCING COMPANY Pogo is an independent oil and gas exploration and production company with a well-balanced portfolio of domestic and international properties. Over the 31 years of our existence, Pogo has established a proven track record of growth through exploration and acquisition. On March 14, 2001, we acquired North Central Oil Corporation, a privately held oil and gas company, for consideration of 12,615,816 shares of Pogo common stock, $344,711,000 in cash and the assumption of $78,600,000 in debt. The North Central acquisition added 537.2 Bcfe to complement Pogo's existing reserves base and provides Pogo with new core areas with growth potential. The Pogo common stock being offered through this prospectus are some of the shares that were paid as consideration in the North Central transaction. In this discussion about Pogo, terms such as "we", "our" and "us" refer to Pogo and its subsidiaries. Our proven hydrocarbon reserves have increased each year since 1991, principally through exploration and development of our properties and, to a lesser extent, selective corporate acquisitions, such as the acquisition of North Central, and the acquisition of producing properties in our core areas. An important measure of our success is our record for replacing the oil and gas which we produce each year. The charts on the inside front cover illustrate the areas in which we operate and our successful track record in increasing our reserves and oil and gas production. During the third quarter of 2001, our properties produced approximately 56% natural gas and 44% liquids. Currently, approximately 75% of our proved reserves are located in North America and approximately 25% are located in the Kingdom of Thailand. We concentrate our exploration efforts in areas where we believe that our technical and operating expertise, competitive acreage position, or ability to quickly take advantage of new opportunities offers us the possibility of superior rates of return. We currently have five significant operating areas: - GULF OF MEXICO -- we have explored for oil and gas and owned leases in the outer continental shelf area of the Gulf of Mexico since the first federal government lease sale over 30 years ago. We currently have interests in 86 lease blocks offshore Louisiana and Texas. Most of our current offshore production is concentrated in five producing areas, principally off the Louisiana coast. We expect the following three large new projects to begin producing oil and gas by the end of the year. - MAIN PASS BLOCKS 61/62 FIELD, which we operate and own 100%, is one of the largest oil discoveries on the U.S. continental shelf in recent years. We plan to complete two large capacity platforms, plus related wells and water injection facilities, one by the end of this year and the other by year-end 2002. - MISSISSIPPI CANYON BLOCKS 661/705 FIELD, which we also operate and have an ownership interest that varies between 50% and 100%, is currently projected to come on-stream in the fourth quarter of 2001 after we finish the tie-in of two wells to a subsea completion. - EWING BANK BLOCK 871 FIELD, in which we own a 50% working interest, has three wells and two subsea completions completed. Final facilities construction is scheduled to be completed in the fourth quarter of 2001 with first production expected by the end of the year. Pogo expects significant new oil and natural gas production in 2002 and 2003 from these fields. S-2 - MADDEN FIELD -- we own between 10% and 13% of the federal units within the large Madden Field in the Wind River Basin of Wyoming, which, net to our interest, contain over 192 Bcfe of proved reserves. This field consists of two distinct pay zones. The shallower zone consists of productive intervals in the Lance, Fort Union, Mesaverde and Cody formations, while the deeper zone, located at depths of more than 25,000 feet, consists of the prolific Madison formation. During the third quarter, Pogo and its industry partners drilled three successful wells in the upper zone, and a fourth well is currently drilling to this objective. Simultaneously, two giant rigs are drilling to the deeper Madison formation. These two deep wells should reach their objectives in April and July of 2002, respectively. - PERMIAN BASIN -- we own interests in approximately 191,000 gross (131,000 net) acres in the Southeastern New Mexico and West Texas portions of the Permian Basin. Commencing in late 1989 and continuing through September 30, 2001, we and our partners drilled 476 wells in the Permian Basin area, including six in the third quarter of 2001. During this 12-year period, 96% of the wells drilled were completed as productive. We have generally achieved rapid cost recovery on our Permian Basin wells because of relatively low capital costs and high initial rates of production. According to the most recently published annual figures, we are the seventh largest producer of crude oil in the State of New Mexico. - GULF COAST ONSHORE -- we currently own interests in 215,430 gross (123,059 net) acres in Louisiana and Texas, including approximately 31,000 gross acres in the Los Mogotes and Hundido Fields, located in South Texas, and 17,000 gross acres in the Thibodaux, Louisiana project area, all of which we operate. - In the LOS MOGOTES FIELD, where we have a 65% working interest, we recently completed two successful wells and currently are operating three rigs, with a fourth rig scheduled to begin drilling in late October 2001. - In our HUNDIDO FIELD, where we have a 99% working interest, we recently completed an eight well drilling program with no dry holes. - Our THIBODAUX, LOUISIANA project area is based on a 17,000 acre state-of-the-art 3-D seismic survey that we recently acquired. We have drilled three successful wells without a dry hole in this area and we are currently drilling another well. We currently expect production from our Gulf Coast onshore properties to rise as a result of production from our newly drilled wells and our active drilling program that we have planned for the fourth quarter of this year. - KINGDOM OF THAILAND -- we own a 47% working interest in a 714,000 gross acre Block B8/32 concession license in the Gulf of Thailand that includes the Benchamas, Tantawan, Maliwan and Jarmjuree Fields. During the third quarter of 2001, our net share of sales from the Benchamas and Tantawan Fields was 63.2 MMcf per day of natural gas and 16,310 Bbls per day of liquids. As a result of a preliminary agreement that we recently reached with PTT Public Company Limited, the purchaser of Pogo's natural gas production in Thailand, Pogo anticipates that its natural gas volumes could increase over the next several months by 15 to 30 MMcf per day. During the third quarter, Pogo and its industry partners continued to enhance the crude oil capabilities of Block B8/ 32. Development drilling resulted in seven new producing wells in the "A" platform area of Benchamas Field. Five new platforms have been constructed and are en route to the Benchamas Field. When fitted with platform decks, drilled and connected, at least four dozen new wells will begin producing by about mid-year 2002. Meanwhile, the jacket and deck for the first Maliwan Field production platform are in place and drilling is now underway. Initial production is expected from the Maliwan Field in early November 2001. We believe that significant exploratory potential may still exist on the concession. For example, an important exploration discovery that was drilled during the third quarter, the Jarmjuree No. 8 well located in the northernmost portion of our S-3 123,000-acre Jarmjuree Field production license area, logged approximately 210 feet of net pay, of which approximately 99 feet are crude oil, and the balance is natural gas. In addition to these core operating areas, Pogo is exploring the potential of our approximately 778,000 acre exploration license located on two blocks in Hungary's prospective Pannonian Basin. We have acquired approximately 140,000 acres of proprietary 3-D seismic data on our license within the last year using state-of-the-art acquisition and processing techniques. Processing of the seismic data is still underway on this complex structural area with initial interpretation of the data indicating a number of promising preliminary leads. Pogo currently expects that it will devote much or all of 2002 to carefully evaluating the 3-D seismic and other data available to us. COMPETITIVE STRENGTHS We believe we are well positioned to continue to build upon our historical success by capitalizing on our strengths, including the following: - We have a diversified portfolio of core properties. We benefit from a portfolio of existing properties that provides geographic diversification while being of sufficient size and potential to enable us to concentrate our resources and regional expertise. This portfolio of core properties permits us to maintain a focused exploration and development program by using the substantial geological and operating expertise that we have gained over years of operating in these areas. We also use our experience to evaluate new opportunities in areas with similar characteristics. - Our existing properties have significant further potential. We believe that our existing properties have significant further potential for increased production and the discovery of additional reserves. We currently expect to spend approximately $385,000,000 during 2001 to develop our existing properties, including drilling approximately 139 gross wells and the installation of over $138,000,000 in net platforms, pipelines and other production facilities. - We try to maintain a balanced risk profile. We try to manage our risk exposure by maintaining a prudent level of participation in our projects. We prefer to operate properties where we believe that our working interest percentage, expertise or ability to control the timing or cost of a project provides a competitive advantage to us and our partners. Currently, we operate all or a portion of 30 of the 86 lease blocks in which we own interests in the Gulf of Mexico. On properties where we are not the operator, we try to have a meaningful working interest so that we can influence operating and development decisions. Generally, we try to obtain a higher level of participation in projects that we view as having potentially high rates of return and relatively low anticipated exploration and development costs, such as our operations in Southeastern New Mexico. Conversely, we will generally seek a lower level of participation in projects that have high drilling or development costs, a long lead time until production can come onstream, or wells that are unusually deep or are considered high risk, such as in the Madden Field. - We possess significant technical expertise. We have an experienced staff of engineers and geoscientists that comprise over 40% of our total full-time personnel. Our personnel's expertise, augmented by data from over 832 gross wells drilled since December 31, 1993, more than 8,200,000 acres of 3-D seismic data, creates a knowledge base which we use to establish our drilling priorities and associated capital budget. S-4 BUSINESS STRATEGY Our business strategy is to maximize profitability and shareholder value by: - increasing hydrocarbon production levels, leading to increased revenues, cash flow and earnings; - replacing and expanding our proven hydrocarbon reserves base; - maintaining appropriate levels of debt and interest expense, and controlling overhead and operating costs; and - expanding exploration and production activities into new and promising geographic areas consistent with our expertise. ---------------------- THE OFFERING Common stock offered by the selling shareholders.......... 6,135,664 shares.

WE ENCOURAGE YOU TO OBTAIN CURRENT MARKET PRICE QUOTATIONS FOR POGO COMMON STOCK. SELLING SHAREHOLDERS In March 2001, we completed the acquisition of North Central through the merger of its parent company, NORIC Corporation, into Pogo. In connection with the merger, we paid $344,711,000 in cash to the former shareholders of NORIC, issued them 12,615,816 shares of our common stock, and assumed approximately $78,600,000 of North Central's debt. In a registration rights agreement we entered into with the former shareholders of NORIC in connection with the merger, we agreed that we would register for resale under the Securities Act of 1933 the 12,615,816 shares of common stock received by them in the merger. This prospectus supplement covers the offer and sale of 6,135,664 shares of our common stock by the former NORIC shareholders and certain of their transferees named in the table below, as well as the 920,349 shares that are subject to the underwriters' overallotment option. In the registration rights agreement, we have agreed to indemnify the selling shareholders against liabilities arising out of any actual or alleged material misstatements or omissions in the registration statement that we have filed relating to this offering or in this prospectus supplement or the accompanying prospectus, other than liabilities arising from information supplied by the selling shareholders for use in the registration statement, this prospectus supplement or the accompanying prospectus. Each selling shareholder, severally but not jointly, has agreed in the registration rights agreement to indemnify us against liabilities arising out of any actual or alleged material misstatements or omissions in the registration S-9 statement or in this prospectus supplement or the accompanying prospectus to the extent that the misstatements or omissions were made in reliance upon written information furnished to us by that selling shareholder expressly for use in the registration statement, this prospectus supplement or the accompanying prospectus. The indemnification by each selling shareholder is limited to the proceeds received by that shareholder from the sale of shares of common stock in this offering. In the registration rights agreement, we have also agreed to pay the costs and fees of registering the shares of common stock covered by the accompanying prospectus, but the selling shareholders have agreed to pay the underwriting discounts and commissions or brokerage commissions incurred in connection with the sale of the shares and the fees and expenses of their counsel. Under a standstill and voting agreement, the former NORIC shareholders have agreed not to acquire any additional shares of our common stock and not to propose any merger, tender or exchange offer, restructuring or other business combination involving Pogo. The standstill and voting agreement also provides that the former NORIC shareholders will not participate in any election contest with respect to Pogo and will vote all their Pogo shares either in accordance with the recommendation of the board of directors, or in equal proportion to the votes cast by other Pogo shareholders. The standstill and voting agreement further provides that, except as provided in the registration rights agreement, the former NORIC shareholders will transfer their shares only to a person who will own, after the transfer, less than 5% of Pogo's voting securities. The shares sold in this offering will no longer be subject to these restrictions when sold to a person other than a party to this standstill and voting agreement.

(1) Based on 53,634,752 shares outstanding as of September 30, 2001. According to a Schedule 13D filed by all of the former NORIC shareholders, these shareholders and RGG Limited Partnership are members of a "group" within the meaning of Section 13(d)(3) of the Securities Exchange Act. The ownership shown for each selling shareholder does not include shares held by the other shareholders that the selling shareholder may be deemed to beneficially own for purposes of Section 13(d). (2) RGG Limited Partnership is the transferee of shares of Pogo common stock acquired in the merger of NORIC into Pogo by three individual former shareholders of NORIC. (3) Mr. Kerlin made charitable gifts of the shares currently held by Wave Hill Incorporated, Bank Street College of Education, Putney School and the Trustees of Columbia University. (4) The total number of shares beneficially owned by the selling shareholders excludes 325,204 shares originally acquired by Mr. Kerlin in the merger that were transferred by him to a third party, which is not participating in this offering. Mr. Kerlin has agreed to provide 151,604 of the shares subject to the underwriters' over-allotment option, representing the over-allotment shares attributable to the shares being sold by Windward Oil & Gas Corporation, of which he is the sole stockholder, and by his charitable donees, Wave Hill Incorporated, Bank Street College of Education, Putney School and the Trustees of Columbia University. The balance of the shares subject to the over-allotment option will be provided by the remaining selling shareholders on a pro rata basis. In connection with the merger of NORIC into Pogo, the former NORIC shareholders provided us a letter of credit from a bank to indemnify us with respect to possible losses we could incur in connection with the merger. The letter of credit was obtained from the bank under a reimbursement agreement among the bank and a number of the selling shareholders. Henrietta Goelet and Robert S. Rich, as trustees of the Trust under Agreement dated December 17, 1976 for the benefit of grandchildren of John S-12 Goelet (the "1976 Trust") is one of the parties to the bank reimbursement agreement. The 1976 Trust pledged all of our shares owned by it to secure its obligations under the bank reimbursement agreement. All of the security interests created by the 1976 Trust's pledge of our shares that will be sold in this offering will be released prior to their sale. Under a shareholder reimbursement agreement, all of the former NORIC shareholders that are not parties to the bank reimbursement agreement are obligated to reimburse the former NORIC shareholders that are parties to the bank reimbursement agreement for a portion of any payments they are required to make to the bank. All 747,546 shares of our common stock currently owned by Gilbert Kerlin and 5,734 of the 14,355 shares of our common stock owned by Arthur Field have been pledged to secure their reimbursement obligations under the shareholder reimbursement agreement. All of the security interests created by Mr. Kerlin's and Mr. Field's pledges of our shares that will be sold in this offering will be released prior to their sale.

Incorporated in 1970, we have, in recent years, established a record of increasing our proven hydrocarbon reserves, principally through exploration, exploitation and development of our properties and the selective acquisition of additional interests in producing properties. Through a portfolio of domestic and international properties, we concentrate our efforts on a mix of both offshore and onshore opportunities that provide a balanced exposure to oil and natural gas production. In recent years, we have concentrated our efforts in selected areas where we believe that our expertise, competitive acreage position, or ability to quickly take advantage of new opportunities offer the possibility of relatively high rates of return. Domestically, we have an extensive Gulf of Mexico reserve and acreage position and we are also active in the Permian Basin of Southeast New Mexico and West Texas and in other areas of Texas and Louisiana. Internationally, through our subsidiary Thaipo Limited, we own an interest in the Block B8/32 concession license in the Gulf of Thailand. We also own interests in Hungary, and in the United Kingdom and Danish sectors of the North Sea. On March 14, 2001, we acquired North Central Oil Corporation ("North Central") for cash and stock through a merger of its parent company, NORIC Corporation, with and into Pogo. North Central's properties are concentrated in four core areas: South Texas, the Rocky Mountains, South Louisiana and the Texas Gulf Coast. You should consider carefully the information under the caption "Risk Factors." Our principal executive offices are located at the following address: Pogo Producing Company 5 Greenway Plaza, Suite 2700 Houston, Texas 77046 (713) 297-5000 (telephone) (713) 297-5100 (facsimile) Additional information concerning Pogo and our subsidiaries, including North Central, is included in our reports and other documents incorporated by reference in this prospectus. See "Where You Can Find More Information." 1 RISK FACTORS Your investment in our common stock involves risks inherent in our business. The value of your investment may decrease. You should carefully consider the following Risk Factors and those in the accompanying prospectus supplement before deciding whether an investment in our common stock is suitable for you. NATURAL GAS AND OIL PRICES FLUCTUATE WIDELY, AND LOW PRICES COULD HAVE A MATERIAL ADVERSE IMPACT ON OUR BUSINESS. Our revenues, profitability and future growth depend substantially on prevailing prices for natural gas and oil. Oil and natural gas market prices have historically been seasonal, cyclical and volatile. The average prices that we currently receive for our production are higher than their historic average, but significantly lower than what we received in early 2001. A future drop in oil and/or gas prices, such as the decline that occurred in 1998, could have a material adverse effect on our cash flow and profitability. A sustained period of low prices could have a material adverse effect on our operations and financial condition. This could also result in a reduction in funds available under our bank credit agreement. Lower prices may also reduce the amount of natural gas and oil that we can economically produce. Among the factors that can cause oil and gas price fluctuation are: - the level of consumer product demand; - weather conditions; - domestic and foreign governmental regulations; - the price and availability of alternative fuels; - political conditions in natural gas and oil producing regions; - the domestic and foreign supply of natural gas and oil; - the price of foreign imports; and - overall economic conditions. THE NATURAL GAS AND OIL BUSINESS INVOLVES MANY OPERATING RISKS THAT CAN CAUSE SUBSTANTIAL LOSSES OR HINDER MARKETING EFFORTS. Numerous risks affect our drilling activities, including the risk of drilling non-productive wells or dry holes. The cost of drilling, completing and operating wells and of installing production facilities and pipelines is often uncertain. Also, our drilling operations could diminish or cease because of any of the following: - title problems; - weather conditions; - fires; - explosions; - blow-outs and surface cratering; - uncontrollable flows of underground natural gas, oil and formation water; - natural disasters; - pipe or cement failures; - casing collapses; - embedded oilfield drilling and service tools; 2 - abnormally pressured formations; - environmental hazards such as natural gas leaks, oil spills, pipeline ruptures and discharges of toxic gases; - noncompliance with governmental requirements; or - shortages or delays in the delivery or availability of equipment or fabrication yards. Offshore operations are also subject to a variety of operating risks peculiar to the marine environment, such as capsizing, collisions and damage or loss from hurricanes or other adverse weather conditions. These conditions can cause substantial damage to facilities and interrupt production. As a result, we could incur substantial liabilities that could reduce or eliminate the funds available for exploration, development or leasehold acquisitions, or result in loss of equipment and properties. Moreover, effective marketing of our natural gas production depends on a number of factors, such as the following: - existing market supply of and demand for natural gas; - the proximity of our reserves to pipelines; - the available capacity of such pipelines; and - government regulations. The marketing of oil and gas production similarly depends on the availability of pipelines and other transportation, processing and refining facilities, and the existence of adequate markets. As a result, even if hydrocarbons are discovered in commercial quantities, a substantial period of time may elapse before commercial production commences. If pipeline facilities in an area are insufficient, we may have to wait for the construction or expansion of pipeline capacity before we can market production from that area. WE MAY NOT BE ABLE TO OBTAIN SUFFICIENT DRILLING EQUIPMENT AND EXPERIENCED PERSONNEL TO CONDUCT OUR OPERATIONS. The recent increase in drilling activity throughout the world has increased the demand for drilling rigs, drilling vessels, supply boats and personnel experienced in the oil and gas industry in general, and the offshore oil and gas industry in particular. Recently we have experienced difficulty and delays in consistently obtaining services and equipment from vendors, obtaining drilling rigs and other equipment at favorable rates, and scheduling equipment fabrication at factories and fabrication yards. In addition, the costs of such services, equipment and personnel have recently risen significantly. No assurance can be given that such services, equipment and personnel will be available in a timely manner, or that operational and fabrication costs will not increase significantly. OUR FOREIGN OPERATIONS SUBJECT US TO ADDITIONAL RISKS. Our ownership and operations in Thailand, Hungary, the North Sea and any other foreign areas where we do business are subject to the various risks inherent in foreign operations. These risks may include the following: - currency restrictions and exchange rate fluctuations; - loss of revenue, property and equipment due to expropriation, nationalization, war, insurrection and other political risks; - risks of increases in taxes and governmental royalties, renegotiation of contracts with governmental entities, and quasi-governmental agencies; 3 - changes in laws and policies governing operations of foreign-based companies; and - other uncertainties arising out of foreign government sovereignty, and inability to fund foreign operations from the United States. United States laws and policies on foreign trade, taxation and investment may also adversely affect international operations. In addition, if a dispute arises from foreign operations, foreign courts may have exclusive jurisdiction over the dispute, or we may not be able to subject foreign persons to the jurisdiction of United States courts. We seek to manage these risks by concentrating our international operations in areas where we believe that the existing government is stable and favorably disposed towards United States oil and gas companies. WE CANNOT CONTROL THE ACTIVITIES ON PROPERTIES WE DO NOT OPERATE; OPERATORS OF THOSE PROPERTIES MAY ACT IN WAYS THAT ARE NOT IN OUR BEST INTERESTS. Other companies operate a significant percentage of the oil and gas properties in which we have an interest. As a result, we have limited influence over operations on some of those properties or their associated costs. Our limited influence on non-operated properties could result in the following: - the operator may initiate exploration or development projects on a different schedule than we prefer; - the operator may propose to drill more wells or build more facilities on a project than we have funds for, which may mean that we cannot participate in those projects or share in a substantial share of the revenues from those projects; and - if the operator refuses to initiate an exploration or development project, we may not be able to pursue the project. Any of these events could significantly affect our anticipated exploration and development activities and the economic value of those properties to us. IF OUR PARTNERS HAVE LIQUIDITY AND CASH FLOW PROBLEMS, WE MAY HAVE DIFFICULTY FINANCING AND DEVELOPING OUR PROJECTS. If oil and gas prices were to decline significantly, some of our partners, particularly the smaller ones, may undergo liquidity and cash flow problems. These problems may lead to their attempting to delay or slow down the pace of drilling or project development to a point that we believe is detrimental to the project. In most cases, we have the ability to influence the pace of capital expenditures and field development through our joint operating agreements. In addition, some partners may be unwilling or unable to pay their share of the costs of projects as they become due. At worst, a partner may declare bankruptcy and refuse or be unable to pay its share of the costs of a project. We could then be required to pay that partner's share of the project costs. MAINTAINING RESERVES AND REVENUES IN THE FUTURE DEPENDS ON SUCCESSFUL EXPLORATION AND DEVELOPMENT. We must continually acquire or explore for and develop new oil and natural gas reserves to replace those produced and sold. Our hydrocarbon reserves and revenues will decline if we are not successful in our drilling, acquisition or exploration activities. Although we have historically maintained our reserves base primarily through successful exploration and development operations, we cannot assure you that our future efforts will be similarly successful. OUR OFFSHORE AND ONSHORE OPERATIONS ARE SUBJECT TO CASUALTY RISKS AGAINST WHICH WE CANNOT FULLY INSURE. Our operations are subject to inherent casualty risks such as blowouts, fires, explosions and marine hazards. If any such event occurred, we could be subject to substantial financial losses due to personal injury, property damage, environmental discharge, or suspension of operations. Because we are a relatively small oil and gas company, the impact on us of one of these events could be significant. Although we 4 purchase customary insurance, we are not fully insured against all risks incident to our business. For some risks, we may not obtain insurance if we believe the cost of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks generally are not fully insurable. If a significant accident or other event occurs and is not fully covered by insurance, it could adversely affect our operations. WE HAVE SUBSTANTIAL CAPITAL REQUIREMENTS. We require substantial capital to replace our reserves and generate sufficient cash flow to meet our financial obligations. If we cannot generate sufficient cash flow from operations or raise funds externally in the amounts and at the times needed, we may not be able to replace our reserves or meet our financial obligations. Our ongoing capital requirements consist primarily of the following items: - funding the remainder of our 2001 capital and exploration budget; - other allocations for acquisition, development, production, exploration and abandonment of oil and gas reserves; and - future dividend payments. Our 2001 capital and exploration budget as established by our board of directors is $350 million (excluding purchased reserves and interest capitalized). We plan to finance anticipated ongoing expenses and capital requirements with funds generated from the following sources: - available cash and cash investments; - cash provided by operating activities; - funds available under our bank credit agreement and banker's acceptance agreement; - capital we believe we can raise through debt and equity offerings; and - asset sales. We believe the funds provided by these sources will be sufficient to meet the remainder of our 2001 cash requirements. However, the uncertainties and risks associated with future performance and revenues, as described in these Risk Factors, will ultimately determine our liquidity and ability to meet our anticipated capital requirements. WE MAY NOT BE ABLE TO PROFITABLY MARKET AND SELL ALL OF THE PRODUCTION FROM OUR CONCESSION IN THAILAND. We may not be able to successfully and profitably process, transport and market all the oil and gas we find and produce on our concession in the Gulf of Thailand. Currently, the only buyer for the natural gas we produce is the Petroleum Authority of Thailand, which maintains a monopoly over gas transmission and distribution in Thailand. Our current gas contract with the Petroleum Authority limits us to delivering approximately 145 million cubic feet of gas per day. Due to an abundance of natural gas under contract to the Petroleum Authority, the Petroleum Authority has generally not taken significantly more than its contractual minimum. Although there are no direct contractual limitations on our ability to produce and market crude oil from our Thailand concession, because a significant portion of the oil we produce from our Thailand concession is associated with natural gas, limits on natural gas production could limit our oil production as well. OUR GAS SALES AGREEMENT IN THAILAND REQUIRES US TO SELL A PORTION OF OUR THAILAND PRODUCTION AT A REDUCED PRICE IF WE DO NOT MEET OUR MINIMUM DELIVERY REQUIREMENTS. We are currently receiving the full contract price on our current production in Thailand. However, if we and our partners fail to deliver the minimum quantities under the gas sales agreement, the Petroleum 5 Authority has the right to reduce the purchase price on an equivalent amount of subsequent deliveries to 75% of the contract price. ECONOMIC CONDITIONS IN SOUTHEAST ASIA CAN HURT OUR CASH FLOW. During 1997 and 1998, Southeast Asia in general, and the Kingdom of Thailand in particular, experienced severe economic difficulties. These problems included sharply reduced economic activity, illiquidity, highly volatile foreign currency exchange rates and unstable stock markets. Although Southeast Asian markets have recovered somewhat, they remain below their recent historic highs. Economic difficulties in Thailand and the volatility of the Thai Baht, Thailand's currency, against the U.S. dollar will continue to have a material impact on our Thailand operations and the prices we receive for our oil and gas production there. YOU SHOULD NOT PLACE UNDUE RELIANCE ON OUR RESERVE DATA BECAUSE THEY ARE ESTIMATES. No one can measure underground accumulations of oil and gas in an exact way. Projecting future production rates and the timing of development expenditures is also an uncertain process. Accuracy of reserve estimates depends on the quality of available data and on economic, engineering and geological interpretation and judgment. As a result, our reserve estimates often differ from the quantities of oil and gas we ultimately recover. To estimate economically recoverable reserves, we make various assumptions regarding future oil and gas prices, production levels, and operating and development costs that may prove incorrect. Any significant variance from those assumptions could greatly affect our estimates of economically recoverable reserves and future net revenues. You should not assume that the present value of future net cash flows from our proved reserves included or incorporated by reference in this prospectus is the current value of our estimated natural gas and oil reserves. In accordance with Securities and Exchange Commission requirements, we base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the net present value estimate. WE FACE SIGNIFICANT COMPETITION, AND WE ARE SMALLER THAN MANY OF OUR COMPETITORS. The oil and gas industry is highly competitive. We compete with major and independent natural gas and oil companies for corporate and property acquisitions. We also compete for the equipment and labor required to operate and develop properties. Many of our competitors have substantially greater financial and other resources than we do. As a result, those competitors may be better able to withstand sustained periods of unsuccessful drilling. In addition, larger competitors may be able to absorb the burden of any changes in federal, state and local laws and regulations more easily than we can, which would adversely affect our competitive position. These competitors may be able to pay more for exploratory prospects, corporate acquisitions, and productive natural gas and oil properties and may be able to define, evaluate, bid for and purchase a greater number of properties and prospects than we can. Our ability to explore for natural gas and oil prospects, make strategic corporate acquisitions, and to acquire additional properties in the future will depend on our ability to conduct operations and to evaluate and select suitable properties and transactions in this highly competitive environment. Moreover, the oil and gas industry itself competes with other industries in supplying the energy and fuel needs of industrial, commercial and other consumers. Increased competition causing oversupply or depressed prices could greatly affect our operational revenues. OUR COMPETITORS MAY USE SUPERIOR TECHNOLOGY. Our industry is subject to rapid and significant advancements in technology, including the introduction of new products and services using new technologies. As our competitors use or develop new technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to implement new technologies at a substantial cost. In addition, our competitors may have greater financial, technical 6 and personnel resources that allow them to enjoy technological advantages and may in the future allow them to implement new technologies before we can. We cannot be certain that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. One or more of the technologies that we currently use or that we may implement in the future may become obsolete, and we may be adversely affected. For example, marine seismic acquisition technology has been characterized by rapid technological advancements in recent years and further significant technological developments could substantially impair our 3-D seismic data's value. WE ARE SUBJECT TO LEGAL LIMITATIONS THAT MAY ADVERSELY AFFECT THE COST, MANNER OR FEASIBILITY OF DOING BUSINESS. We and our subsidiaries are subject to various foreign and domestic laws and regulations on taxation, exploration and development, and environmental and safety matters in countries where we own or operate properties. Many laws and regulations require drilling permits and govern the spacing of wells, the prevention of waste, rates of production and other matters. These statutes and regulations, and any others that are passed by the jurisdictions where we have production, could limit the total number of wells drilled or the total allowable production from successful wells, which could limit revenues. WE ARE SUBJECT TO VARIOUS ENVIRONMENTAL LIABILITIES. We could incur liability to governments or third parties for any unlawful discharge of oil, gas or other pollutants into the air, soil or water, including responsibility for remedial costs. We could potentially discharge oil or natural gas into the environment in any of the following ways: - from a well or drilling equipment at a drill site; - leakage from storage tanks, pipelines or other gathering and transportation facilities; - damage to oil or natural gas wells resulting from accidents during normal operations; and - blowouts, cratering or explosions. Environmental discharges may move through soil to water supplies or adjoining properties, giving rise to additional liabilities. Some laws and regulations could impose liability for failure to notify the proper authorities of a discharge and other failures to comply with those laws. Environmental laws may also affect our costs to acquire properties. We do not believe that our environmental risks are materially different from those of comparable companies in the oil and gas industry. However, we cannot assure you that environmental laws will not, in the future, result in decreased production, substantially increased operational costs or other adverse effects to our combined operations and financial condition. Pollution and similar environmental risks generally are not fully insurable. HEDGING TRANSACTIONS MAY NOT COMPLETELY MITIGATE DECLINES IN OIL AND GAS PRICES. We cannot predict future oil and gas prices with certainty. To reduce our exposure to price fluctuations, at times we enter into contracts to hedge against future market price changes on a portion of our production. Historically, we have not entered into hedging transactions exceeding 50 percent of our total oil and gas production on an energy equivalent basis for any given period. As of August 3, 2001, we had purchased options to sell 70 million cubic feet of natural gas production per day through December 2002. These contracts give us the right, but not the obligation, to sell natural gas at a sales price of $4.25 per Mcf through March 2002 and $4.00 per Mcf for the period from April 2002 through December 2002. These contracts are designed to guarantee us a minimum "floor" price for the contracted volumes of production without limiting our participation in price increases during the covered period. 7 FORWARD-LOOKING STATEMENTS Certain of the statements contained or incorporated by reference in this prospectus are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

All subsequent written and oral forward-looking statements attributable to Pogo or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. Pogo's actual results could differ materially from those anticipated in these forward-looking statements as a result of the risk factors set forth below and other factors set forth in or incorporated by reference in this prospectus. These factors include: - the cyclical nature of the oil and natural gas industries - our ability to successfully and profitably find and produce oil and gas - uncertainties associated with the United States and worldwide economies - current and potential governmental regulatory actions in countries where Pogo owns an interest - substantial competition from larger companies - Pogo's ability to implement cost reductions - operating interruptions (including leaks, explosions, fires, mechanical failure, unscheduled downtime, transportation interruptions, and spills and releases and other environmental risks) - fluctuations in foreign currency exchange rates in areas of the world where Pogo owns an interest, particularly Southeast Asia, and - covenant restrictions in Pogo's indebtedness. Many of those factors are beyond Pogo's ability to control or predict. We caution you not to put undue reliance on forward-looking statements or to project any future results based on such statements or on present or prior earnings levels. All subsequent written and oral forward-looking statements attributable to Pogo and persons acting on our behalf are qualified in their entirety by the cautionary statements contained in this section and elsewhere in this prospectus. USE OF PROCEEDS We will not receive any proceeds from sales of common stock by the selling shareholders. SELLING SHAREHOLDERS In March 2001, we completed the acquisition of North Central Oil Corporation through the merger of its parent company, NORIC Corporation, with and into Pogo. In connection with the merger, Pogo paid former shareholders of NORIC $344,711,000 in cash and issued them 12,615,816 shares of Pogo common stock covered by this prospectus. 8 In a registration rights agreement we entered into with the selling shareholders in connection with the merger, we agreed that we would register for resale under the Securities Act of 1933 the 12,615,816 shares of common stock received by the selling shareholders in the merger. This prospectus covers the offer and sale of the shares of common stock by each of the selling shareholders set forth in the table below or their donees of 500 shares or less. In the registration rights agreement, we have agreed to indemnify the selling shareholders against liabilities arising out of any actual or alleged material misstatements or omissions in the registration statement that we have filed relating to this offering or any related prospectus or prospectus supplement, other than liabilities arising from information supplied by the selling shareholders for use in the registration statement, prospectus or supplement. Each selling shareholder, severally but not jointly, has agreed in the registration rights agreement to indemnify us against liabilities arising out of any actual or alleged material misstatements or omissions in the registration statement or any related prospectus or prospectus supplement to the extent that the misstatements or omissions were made in reliance upon written information furnished to us by the selling shareholder expressly for use in the registration statement, prospectus or supplement. The indemnification by any selling shareholder is limited to the proceeds received by that shareholder from the sale of shares of common stock under this prospectus. In the registration agreement, we also have agreed to pay the costs and fees of registering the shares of common stock covered by this prospectus, but the selling shareholders have agreed to pay underwriting discounts and commissions or brokerage commissions incurred in connection with the sale of the shares and fees and expenses of their counsel. Except for their ownership of shares of our common stock, the contractual relationships provided in the registration agreement and the transactions described above, the selling shareholders have held no position or office with Pogo and have had no material relationship with us or with any of our predecessors or affiliates within the past three years. The following table presents the name of each selling shareholder, the number of shares of common stock that each selling shareholder owns, the number of shares of common stock that may be offered for resale by each selling shareholder under this prospectus and the percent of outstanding shares of common stock each selling shareholder owned prior to this offering. Since the selling shareholders may sell all, some or none of their shares, no estimate can be made of the aggregate number of shares of common stock that will be sold or that will be owned by each selling shareholder upon completion of this offering. If a selling shareholder transfers more than 500 shares of common stock by gift, pledge or other non-sale transfer after the effective date of the registration statement of which this prospectus is a part, the donee, pledgee or transferee may make no offer or sale under this prospectus until such person has notified us and a supplement to this prospectus has been filed or an amendment to the related registration statement has become effective. Subject to contractual restrictions on transfer in the registration rights agreement and a related standstill and voting agreement, we will supplement or amend this prospectus to include additional selling shareholders upon request and upon provision to us of all required information. We prepared this table based on information contained in public filings made by the selling shareholders named in this table or provided separately to us by such selling shareholders, and we have not sought to verify the information.

(2) RGG Limited Partnership is the transferee of shares of Pogo common stock acquired in the merger of NORIC Corporation into Pogo by three individual former shareholders of NORIC Corporation. The selling shareholders listed above and their permitted transferees under the terms of the registration rights agreement may sell up to all of the shares of the common stock shown above under the heading "Shares Offered" pursuant to this prospectus in one or more transactions from time to time as described below under "Plan of Distribution." Permitted transferees under the registration rights agreement may include affiliates of or successors in interest to the selling shareholders or persons or entities obtaining common stock from the selling shareholders as a gift, on foreclosure of a pledge, in a distribution or dividend of assets by an entity to its equity holders or in another private transaction. However, the selling shareholders are not obligated to sell any of the shares of common stock offered by this prospectus. TRADING LIMITATIONS AND RESTRICTIONS Pogo entered into a registration rights agreement with the selling shareholders in connection with Pogo's acquisition of North Central. The following summary of that agreement and provisions of the related standstill and voting agreement is qualified by reference to those agreements itself, which are incorporated by reference into this document. Initial restriction on trading; registration of shares. The selling shareholders are generally prohibited from publicly selling any Pogo shares until September 11, 2001, which is 181 days after the effective date of the North Central acquisition. Pogo agreed to use its reasonable best efforts to register for resale the shares of common stock held by the selling shareholders by September 11, 2001. Pogo must also use its reasonable best efforts to keep the registration statement covering such resales effective until March 14, 2003. Sale of registered shares; Limitations on volume with respect to registered shares other than in underwritten public offerings. This prospectus may be used to sell the shares of the selling stockholders from time to time in open market and private transactions, subject to a limitation of 1,000,000 shares during any period of 90 consecutive days during the period that begins on September 11, 2001 and ends on September 10, 2002. In addition, until March 14, 2003 and for as long as the selling shareholders are considered "affiliates" of Pogo, they will also be subject to volume limitations under Rule 144 of the Securities Act of 1933. Underwritten public offerings; Limitations on volume with respect to registered shares. In addition to the shares that may be sold by the selling shareholders as discussed above, the selling shareholders may sell their shares in underwritten public offerings. The registration rights agreement provides for one underwritten public offering. At the discretion, and upon the request, of holders of at least 50% of the shares offered hereby, selling shareholders may sell not less than 4,000,000 shares nor more than 7,000,000 shares offered hereby as part of an underwritten public offering that results in a broad distribution of the selling shareholders' shares. Pogo has agreed to assist the selling shareholders and to pay 11 its own expenses (but not the underwriter's discount, if any) in connection with such an offering. Additional information regarding any underwritten offering made at the request of the selling shareholders will be contained in a supplement to this prospectus. In addition to the one underwritten public offering that the selling shareholders may initiate, at the selling shareholders' request, Pogo has agreed to include the selling shareholders shares in any registration statement Pogo files for itself or for the account of any other shareholders. The selling shareholders' ability to "piggyback" on other public offerings is subject to the maximum number of shares which the managing underwriter of that offering considers appropriate, with registered shares to be allocated first to Pogo or the shareholders for whose account the offering is being conducted, and then to the selling shareholders requesting to participate in the offering. "Lock-up agreements." Each selling shareholder participating in an underwritten offering must enter into a customary lock-up agreement under which the seller agrees not to sell Pogo shares for a period up to 90 days after the closing of the relevant offering. Other agreements. The registration rights agreement also contains customary provisions relating to procedures for registration, blackout periods and indemnification. PLAN OF DISTRIBUTION The selling shareholders have advised us that they may offer and sell the shares of common stock offered by this prospectus from time to time in one or more of the following transactions: - through the New York Stock Exchange, the Pacific Exchange, or any other securities exchange that quotes the common stock; - in the over-the-counter market; - in transactions other than on such exchanges or in the over-the-counter market (including negotiated transactions and other private transactions); - in short sales of the common stock, in transactions to cover short sales or otherwise in connection with short sales; - by pledge to secure debts and other obligations or on foreclosure of a pledge; - through put or call options, including the writing of exchange-traded call options, or other hedging transactions related to the common stock; or - in a combination of any of the above transactions. The selling shareholders also have advised us that the hedging transactions that may be entered into by the selling shareholders from time to time may include one or more of the following transactions, in which a selling shareholder may: - enter into transactions with a broker-dealer or any other person in connection with which such broker-dealer or other person will engage in short sales of the common stock under this prospectus, in which case such broker-dealer or other person may use shares of common stock received from the selling shareholder to close out its short positions; - sell common stock short itself and redeliver shares offered by this prospectus to close out its short positions or to close out stock loans incurred in connection with their short positions; - enter into option or other types of transactions that require the selling shareholder to deliver common stock to a broker-dealer or any other person, who will then resell or transfer the common stock under this prospectus; or - loan or pledge the common stock to a broker-dealer or any other person, who may sell the loaned shares or, in an event of default in the case of a pledge, sell the pledged shares under this prospectus. 12 The selling shareholders have advised us that they may use broker-dealers or other persons to sell their shares in transactions that may include one or more of the following: - a block trade in which a broker-dealer or other person may resell a portion of the block, as principal or agent, in order to facilitate the transaction; - purchases by a broker-dealer or other person, as principal, and resale by the broker-dealer or other person for its account; or - ordinary brokerage transactions and transactions in which a broker solicits purchasers. Broker-dealers or other persons may receive discounts or commissions from the selling shareholders, or they may receive commissions from purchasers of shares for whom they acted as agents, or both. Broker-dealers or other persons engaged by the selling shareholders may allow other broker-dealers or other persons to participate in resales. The selling shareholders may agree to indemnify any broker-dealer or agent against certain liabilities related to the selling of the shares, including liabilities arising under the Securities Act of 1933. If a broker-dealer purchases shares as a principal, it may resell the shares for its own account under this prospectus. A distribution of the common stock by the selling shareholders may also be effected through the issuance by the selling shareholders or others of derivative securities, including warrants, exchangeable securities, forward delivery contracts and the writing of options. The selling shareholders have advised us that they may sell their shares at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices and that the transactions listed above may include cross or block transactions. The aggregate proceeds to the selling shareholders from the sale of the shares of common stock will be the purchase price of the shares less the aggregate agents' discounts or commissions, if any, and other expenses of the distribution not borne by us. The selling shareholders and any agent, broker or dealer that participates in sales of common stock offered by this prospectus may be deemed "underwriters" under the Securities Act of 1933 and any commissions or other consideration received by any agent, broker or dealer may be considered underwriting discounts or commissions under the Securities Act of 1933. The selling shareholders have advised us that they may agree to indemnify any agent, broker or dealer that participates in sales of common stock against liabilities arising under the Securities Act of 1933 from sales of common stock. Instead of selling common stock under this prospectus, the selling shareholders have advised us that they may sell common stock in compliance with the provisions of Rule 144 under the Securities Act of 1933, if available. We have informed the selling shareholders that the anti-manipulation provisions of Regulation M under the Securities Exchange Act of 1934 may apply to their sales of common stock. The term "selling shareholders" also includes affiliates of and successors in interest to the selling shareholders and persons and entities who obtain common stock from selling shareholders as a gift, on foreclosure of a pledge, in a distribution or dividend of assets by an entity to its equity holders or in another private transaction, subject to the contractual restrictions on transfers in the registration rights agreement and standstill and voting agreement. Additional information related to the selling shareholders and the plan of distribution may be provided in one or more prospectus supplements.
