Contrary to the assertion in the letter, Pioneer's activities did not create any environmental damage and our operations did not disregard environmental practices to protect the Beaufort Sea. The incident, as referred to in Mr. Hamel's letter, occurred on March 28, 2003 during operations to drill an exploration well from a grounded ice pad in the shallow waters of the Beaufort Sea approximately four miles from shore near the mouth of the Colville River. In this area, the sea is only about ten feet deep. During the winter months, sea ice forms to a depth of about four to six feet. On top of the sea ice, an ice pad approximately thirty feet thick covering an area of about five acres was constructed to provide a stable platform for a drilling rig and associated equipment. The weight of the ice pad pushed the existing sea ice to the sea floor leaving the top of the pad approximately twenty feet above sea level. As with a natural island, the ice pad creates a drilling island entirely grounded on the sea bed with sufficient strength necessary to safely support the drilling unit and support facilities. After drilling the well, scientific logging tools were used to evaluate the existence and quantity of hydrocarbons. The well was drilled for information purposes only and 700 G STREET. STE, 600 . ANCHORAGE, ALASKA 99501 . MAIN: (907) 277-2700 ) ) The Honorable Pete Domenici May 16, 2005 Page 2 following evaluation, operations were undertaken to plug and abandon the well. During the abandonment operations, approximately 480 gallons of water containing a de minims concentration of potassium chloride was accidentally spilled into the well cellar while cutting off the conductor pipe. The well cellar on an ice pad is a hole cut into the ice to allow installation of blow out preventers. The well cellar is about six feet deep with a bottom about fourteen feet above sea level. The well cellar is lined with galvanized steel material to protect the integrity of the hole. Immediately after the spill, the water was recovered from the well cellar with a vacuum hose and was properly disposed. Following removal of the rig, a backhoe was brought in to clean out and properly dispose of ice that became dirty from the spilled water. None of the spilled liquid was released to the environment. Pioneer erred in not imlnediately reporting the spill. It was the opinion of experienced personnel on site, including a contract environmental specialist, that the spill, contained within the cellar and immediately recovered, was not reportable under Alaska state guidelines. This assessment proved to be incorrect, and when the error was discovered, the spill was reported and investigated by the Alaska Department of Environmental Conservation (ADEC). An ADEC inspector visited the site and provided the enclosed written assessment. Pioneer was reprimanded for its failure to timely report the spill, but the ADEC assessment concluded that the liquid was properly cleaned up with no impact to the marine environment. Mr. Hamel's allegation that Pioneer willfully disposed of toxic fluids into the Beaufort Sea to save the cost of disposal is incorrect in the following ways: 1) The cost to dispose of 480 gallons of water is less than $100, a tiny fraction of the $30 million Pioneer expended on its Beaufort Sea exploration program in early 2003. In addition, the 480 gallons of water spilled represents less than 0.5% of the fluids used in the operation. All fluids were properly disposed at the end of the operation. 2) The well cellar was a hole cut into a massive ice pad above sea level with no conduit to seawater. In fact, the entire area around the ice pad consisted of frozen seawater. 3) Water with small concentrations of potassium chloride, an inorganic salt, is not toxic and when disposed properly is considered a non-hazardous waste. Pioneer is committed to environmentally responsible development and strives to be a good steward in our operating areas around the world. Pioneer and its predecessor companies have operated in environmentally sensitive areas such as the Gulf of Mexico ) ) The Honorable Pete Domenici May 16, 2005 Page 3 for more than 25 years. We consider the environmental standards and level of regulatory scrutiny in Alaska to be the most stringent of any area in which we operate worldwide. Be~r¿;Y /f;/Ijõ£ IÆh~~{þ¡ .

According to Tom, the drilling occurred without any discharge. All potential discharges were collected and disposed of in a nearby class 2 injection well. Without a discharge, NPDES would not apply, which explains why they are not covered by an NPDES permit.

Pioneer Natural Resources Co. said all three wells it drilled in shallow water northwest of the Kuparuk oil field struck sandstone filled with oil but the sands were "too thin to be considered commercial." Pioneer added, however, that it found Jurassic rocks, which are deeper and older, and one well flowed at a sustained rate of 1,300 barrels of oil per day. The well will undergo a pressure buildup test to determine whether the find is worth developing, the company said.

This permit to redrill does not exempt you from obtaining additional pennits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test.

Drill 20 ft of new hole and circulate the hole clean with consistent mud weight in/out. Pull up into the casing shoe. 3. Perform a Leak Off Test: · Shut the well in. RU cement pump. · Record the fluid volume in the cement unit's tanks. · The estimated Leak Off surface pressure with 9.5 ppg mud is = 608 psi. · As a guide, use the data from the casing test to determine the approximate volume of mud required to reach 608 psi on the LOT. · Bring the pump on line at 0.1 - 0.2 bpm & keep the rate constant. · Record the pressure for every tenth of a bbl pumped. · Continue pumping until the pressure breaks over plus 1 bbl. · Plot the data to determine the Leak off pressure at the shoe as EMW. · Repeat the test if needed. Cementinf,1 Program: (attached) Well Control: / Surface hole will be drilled with a diverter.

H25: / H2S has not been seen/reported on any of the offset wells: Kalubik #1, Kalubik #2, Kalubic #3, E. Harrison Bay #1 & Thetis Island #1. As a precaution, however, H2S monitors will be used at all times and 30-minute air packs will be available. Ooogaruk #1 Drilling Program Page 4 DRILL AND COMPL .fION PROCEDURE -) Pre-RiQ Work: 1. The 13-3/8" non-insulated conductor will be driven to ± 115' RKB. 2. NU the multi-bowl casing head on the 13-3/8" conductor. 3. Spot and fill the reserve fuel tank with spill containment. 4. Spot and fill the reserve water tank with spill containment. 5. Stockpile mud and cement materials on/near locati.on. 6. Stockpile casing and tubing on/near location. 7. Ensure communications are up and running. 8. Ensure the permits are in order. 9. Ensure all training requirements have been met. 10. Establish polar bear perimeter and watch. 11. Notify the AOGCC 24 hours prior to spud and BOP test. 12. Notify ACS prior to MIRT. DrillinQ Hazzards: 1. The shallow hazard survey indicates the presents of no discernable hazards. In addition, none of the offset wells reported any hazardous conditions while drilling near surface. 2. Gas generated from drilling through "hydrates" is expected to be minimal. Again, 'offset wells reported only minor volumes of gas while drilling the surface hole. The reduced hole size planned for this well with minimize the volume of gas generated while drilling. 3. Gumbo and other reactive formations constitute potential hazards from surface to TD. The planned use of inhibitive drilling fluid should minimize this problem, however, caution should be used at all times brause swabbing and packing off could occur at any depth. 4. No H2S is expected in this well, howeyer, H2S monitors will be used at all times and the crews should be made ware of this potential hazard. 5. No abnormal pressure is expected based upon offset data. The maximum expected mud weight is 9.8 ppg, however, the crews should be alert to this potential hazard as well. BOP tests "kick drill" will be conducted in accordance with AOGCC regulations. 6. Lost circulation represents a potential hazard in this area. An adequate supply of LCM will be stockpiled on location for use if needed. The drilling fluid will be maintained to minimize ECD, surge and swab pressures. Lost circulation is considered to be a low potential hazard and little if any losses were reported on the offset wells. RiQ Operati'ons: 1. MIRU Drilling Rig, camp and ball mill with berms and herculite as required. 2. Take on water and mix spud mud. Make sure all solids control equipment is operating at capacity. Set the solids control van/skid (if used) and be sure it's operational. Set the cutting tank, etc. / 3. NU the BOP's on the wellhead with the diverter and diverter spool. RU the diverter lines (10" minimum) as per AOGCC regulations. Function test the diverter system. Use a test plug; test the rams, casing head and flanges to 2000 psi before the rig is accepted. 4. Clean out the 13-3/8" drive pipe. PU the 9-7/8" BHA with MWD/GRlRES and a performance (straight hole) motor. While drilling the surface hole, stop and circulate the hole clean at 1000' and at 2000'. Try not to out drill the solids control equipment: control drill if necessary. Record MWD surveys every 300 ft. Drill the surface hole to +/- 3000'. Drill the hole to fit the casing including 10-15' of rat hole. Ooogaruk #1 Drilling Program Page 5 5. At casing point, circuL ) the hole clean. Rotate the drill strir, )t ~ 120 rpm to help clean the hole. Make a 20 stand wiper trip. Circulate bottoms up again. Drop a magnetic multi- shot and POOH. LD BHA. 'If th~ole is "tight", pump out of the hole using the top drive. 6. NU and test 7-5/8" casing rams. RU casing tools. Make up the "Combo Tool" on a stand of drill pipe and stand it back. Run and cement the 7-5/8", 29.7# surface casing. A port collar will be run in the casing string one full joint below the mandrel hanger (±'25' below the mud line). Use PDC drill-able float equipment and centralizers on every third joint to surface. Run a cement basket 1 joint below the port collar. Land the fluted hanger. 7. Circulate at least one full casing volume and adjust the rheology of the mud as needed. Pump a "marker pill" and record the pump strokes (bbls) shoe to surface.

Ooogaruk #1 Drilling Fluids Program This exploration well will be drilled from an off-shore ice island west of Oliktok Point on the North Slope of Alaska. The well will· be drilled as "slim hole" to minimize waste. The well will be spudded with a 9-7/8" bit and drilled to the surface casing point of ± 3000' TMD where 7-5/8" casing will be run and c'emented to surface. A 6-3/4" hole will then be drilled to a final well TD of ± 7500' TMD. At TD, a 5-112" x 3-112" tapered liner will be run and cemented. Primary targets for this well will include the middle Brookian sands, Torok sand and Kuparuk sands with other possible oil bearing sands being present. An inhibited KCI/Polymer mud will be used to drill this well from spud to the core point on this well which is ± 4250' (the middle Brookian target). At the core point, a specially fonnulated 9.8 ppg core fluid (BaraDril-N System) will be used to core the well. After coring the well, the BaraDril-N system will be run and maintained as an inhibited KCI/Polymer mud to the final TD of the well. As a general drilling fluids plan, spud the well with inhibited 9.0 ppg KCI/Polymer mud. The mud weight will then be held between 9.0-10.0 ppg to the surface casing point unless hole conditions dictate otherwise. Our primary focus for surface hole drilling operations will be adequate mud weight for well control and sufficient mud viscosity for hole cleaning. This spud mud is fonnulated with several mechanisms to provide effective wellbore stabilization and to reduce drilling waste, i.e., ionic inhibition (KCI), polymer encapsulation (PHP A) and anionic bonding (Clayseal). From the surface shoe to TD, the continued use of the inhibited KCI/Polymer mud is suggested with again the primary focus being to provide effective wellbore stabilization and the reduction of drilling wastè. . When drilling this interval of the well a certain amount of new mud will be required coming out of the surface casing to re-adjust the low gravity solids content to acceptable limits for continued drilling operations. The mud weight for this interval will range from 9.6 ppg at drill-out of the surface casing to 9.8 ppg by 4000' (middle Brookian target) and to 9.8-10.3 ppg by the top of the Kuparuk sands. This current mud plan would put the mud filtrate salinity in the 60K-90K ppm range for drilling the pay-zones.

Maintain a sufficient quantity of Driltreat (lecithin) to accomplish a 2 ppb treatment in the event gas hydrates are noted. 2. Lime and zinc carbonate should be on location for H2S contingency. 3. Maintain an adequate supply of barite to increase the mud weight by 1.5 ppg at all times. 4. Due to the remote nature of this location, maintain an adequate supply of LCM and the other mud additives, which may be required to support this drilling program. Surface Interval (9-7/8'''' Hole to 3,,000' TVD/TMD) The surface interval of this well will be drilled with a KCI/Polymer mud as fonnulated below: 9.0 Ppg Fonnulation Fresh Water KCI NaCI EZ Mud DP Clayseal P AC-L/R Barazan-D KOH Aldacide-G Baroid Baracor 700 .95 bbl 44 lbs o .75 lbs .84 gal .5lbs 1-21bs .1lbs .2lbs o 1.0 , (ionic inhibition) (polymer encapsulation) (anionic bonding) (API filtrate of6-12 cc's) (as required for an initial 35 YP) (pH = 8.5-9) (X-Cide 207 for rig maintenance) (as needed) (corrosion inhibitor) Spud the well with maximum flow rates (550-650 gpm assuming 9-7/8" hole w/3-l/2" drill pipe) to ensure good cuttings transport. Target an initial yP in the 45 range then adjust as dictated by the actual hole cleaning requirements of the well (minimum gravel is anticipated - mostly clays and sand). Reduce viscosity as allowed (previous wells in the area have TD'd the surface hole with a ± 25 YP). However, if hole cleaning appears to be inadequate, do not hesitate to quickly raise the viscosity as required. Polymer viscosity in the fonn of Barazan-D additions should be utilized to provide rheological support as needed. Utilize high viscosity sweeps to supplement the hole cleaning capabilities of the system. Circulate while rotating at ~ 120 rpm for maximum hole cleaning. With an initial mud density of 9.0 ppg, please note the other issues of concern as listed below: 1. Alert all members of the drilling team of the potential of encountering gas hydrates. 2. A mud weight of ± 9.6 ppg is currently programmed for drilling the gas hydrate interval of the well, if encountered. Note: offset wells encountered only minimal gas hydrates. 3. If gas hydrates are encountered, treat the system with 2.0 ppb of Driltreat (Lecithin) and Y2% by volume BDF-263. Also, control drill if necessary. 4. Maintain the mud as cool as possible (under 50°F if possible). Efforts to keep the fluid cool include mudding up with cold water and diluting the mud with cold water. The freeze point of the base fluid is less than 20° F. The Baroid mud plant in Prudhoe Bay can be utilized to supply the initial volume of fluid for the spud. Make every effort to maintain the system as clean as possible through the nonnal dilution process and maximization of solids control equipment application. As this mud will be fonnulated with soluble salts for the mud density requirement, the Baroid Solids Van should be considered for use to enhance/support the overall solids control efforts. Mud maintenance issues for this interval of the well are as follows: Ooogaruk. #1 Page 2 11/21/2002 ) ) 1. If possible, use pre-mixed KCl water to maintain volume while drilling ahead. The density of the KCl solution should be based upon mud weight requirements at any given point of the well. 2. Use PAC's for API filtration control. Target 6-12 cc's initially, dropping the fluid loss to the 6 cc range prior to running casing at the surface casing point. 3. Hold the pH in the 8.5 - 9.0 range with KOH. 4. By material balance, maintain the Clayseal concentration in the 2% by volume range. 5. By material balance, maintain the EZ Mud DP in the .75 - 1.0 ppb range. 6. Control penetration rates based upon the ability of the surface system to process the drilling mud. Use as "fine mesh" shaker screens as possible. 7. Daily additions of X-Cide 207 are needed to control bacterial action. 8. Corrosion inhibitors should be run (1 ppb Baracor 700 / .5 ppb Barascav D). 9. Keep MBT as low as possible (generally <12 ppb). Heavy amounts of clay may be present and may require additions of ConDet and BDF-263 to reduce BHA balling and screen blinding. Sweeping the hole with high viscosity sweeps prior to the short trip at TD and again prior to coming out of the hole to run the surface casing is recommended. If possible, reduce the fluids rheology to <20 yP after the casing is on bottom prior to starting the cement job.

Increase the mud weight as needed with KCl so as to allow maximum application of centrifuge support to optimize solids control efforts. KCl will be used for ionic inhibition and for the basic density requirements of the system. CaC03 -may be used as necessary. Initially, target a mud density of± 9.6 ppg with a yP in the 10 to 20 range and maintain until out of the sticky clays often found within this interval of the well. Then, adjustYP as required with Barazan-D polymer as needed for efficient hole cleaning. If screen blinding from heavy clays is a problem, use ConDet and BDF-263 treatments. Once through the sticky clays, increase the yP to the 15-25 range with Barazan-D to ensure good hole cleaning support. Flow rates of 250 - 275 GPM will provide an annular velocity of 200' /min which should suffice in this near vertical hole. Maintain the 9.6 ppg mud weight down to 4000'. Increase the density as needed (9.8 ppg) prior to drilling the middle Brookian target. Minimize LGS's through the constant/efficient use of solids control equipment and dilution as required. Below 4000', maintain the API filtrate ~ 6 with PAC's. Use KCl brine for daily volume additions (the brine density should be based on the mud weight objectives at the time). Daily additions of X-Cide 207 should be made to control bacterial action. KOH should be used for pH control. Keep MBT as low as possible « 12 ppb), however, do not revert to "dump & dilute" practices unless absolutely necessary. Middle Brookian Coring (4200') A specifically designed core fluid (BaraDril-N System) will be prepared to satisfy the coring objectives of the middle Brookian target on this well. The fluid will be very similar in chemical design to the KClIPolymer muds used to drill to core point and should be compatible with the displacement objectives Ooogaruk #1 Page 3 11/21/2002 ) of the well. The core fluid design will include KCI for ionic inhibition, starch and· "specially" sized calcium carbonates for effective filtration control and bridging and "clean" hio-polymers for effective rheological support. For fluid density on this well, the sized calcium carbonates will be sufficient. After drilling to the core point, circulate the hole clean. Make a wiper trip to the shoe, circulate bottoms up and then displace the hole with core fluid as follows: 1 Barrel (9.8 ppg) 7% KCI Core Fluid Water, Soda Ash Aldacide G Aquagel Dextrid " PAC L N-Vis KCI Baracarb KOH Baroid .891 bbls .1 ppb .25 ppb (X-Cide 207 for rig maintenance) 5 ppb 8ppb 1.75 ppb .5-.75 ppb (as required for a 15-25 YP) 23.6 ppb (35K ppm salinity) 76 ppb (blending specific to target sand perm) as needed for an 8.0 pH. as needed Target Properties Density HTHP (200 deg.

Just above the HRZ, treat the mud with 4-6 ppb of Baranex to drop the 2000 F. HTHP to 10-12 cc's to provide effective wellbore stability through the lower portion of the well. Then at some point just above the Kuparuk D shale, increase the mud weight to 10.0 ppg and drill ahead to TD adjusting the mud weight as dictated by hole conditions.

Interpretation of these data suggests that no prohibitive condition exists at this location that could pose a potential shallow drilling hazard. The OOOGURUK #1 well will be drilled from an ice pad located approximately 1.75 miles south of Thetis Island. The ice pad will be located in shallow state waters approximately 7.2 miles west of Oliktok Point in the eastern portion of Harrison Bay. The proposed drillwell will be located 1550' SNL & 2050' WEL of Section 31, Township 14 North by Range 8 East (70.526966 . degrees latitude north by 150.168608 degrees longitude west). Geol°I!Y Throughout Quaternary and possibly late Tertiary time sedimentation in this region has been dominated by the Colville River Delta. Thetis Island, located 1.75 miles to the north, is part of the Jones Island chain. These islands are the last reworked remnants of the drowned Pleistocene coastal plain. Superficial sediments include coarse sand, gravel, and boulder lag deposits of Quaternary age. The underlying Pleistocene section, referred to onshore as the Gubik Formation, consists of channelized marine and nonmarine muds, sands, gravels, and low grade coals. Locally the entire Quaternary sequence is less than 900'thick. Underlying the Gubik formation is the Sagavanirktok Formation, which ranges in age from Upper Cretaceous through Tertiary. The Sagavanirktok Formation consists of complexly interbedded marine and nonmarine shelf and delta plain deposits composed of sandstone, shale, and conglomerate. Locally the Sagavanirktok Formation is approximately 3,000' thick and gently dips to the northeast at 10 to 20. The lowermost Sagavanirktok Formation includes a sandstone sequence informally named the U gnu and West Sak sands. This Late Cretaceous to Early Tertiary sandstone sequence is approximately 1,000' thick. These sands bear heavy oil and natural gas in the Kuparuk River and Milne Point Units to the east and southeast. The Sagavanirktok Formation overlies the Schrader Bluff and Torok Formations. These formations collectively referred to as the Colville Group, include fluvial-deltaic sands and shales and marine prodelta deep-water shales. Locally the Colville Group is approximately 2,000' thick. Geophvsics A Conoco/Phillips acquired 3-D seismic grid covering the proposed Oooguruk #1 and Western Geophysical acquired 2-D seismic reflection profiles proximal to the well location were analyzed for potential shallow and intermediate depth drilling hazards (see enclosed seismic/well base map). These same data were correlated with all publicly available shallow hole log data to produce an integrated shallow hazards assessment for the Oooguruk # 1. Specifically as part of this analysis correlations have been made with the Kalubik #1, Kalubik #3, Palm 3W-07, East Harrison Bay # 1 , West Sak # 16 and the Thetis Island # 1 wells which directly offset and surround the Ivik #1 location. Illustrated in line 1541, crossline 835(both intersect the Oooguruk #1) and a reconstruction line that intersects the Kalubik # 1 well, the Oooguruk # 1 location and Thetis Island # 1 well are enclosed for your reference. An Oooguruk # 1 interval velocity/pressure profile exhibit, constructed by integrating all available offset logs, subsurface pressures and seismic data is also attached for reference. Potential Shallow Drilline: Hazards Permafrost Seismic reflection data in proximity to the Oooguruk # 1 well show a unique response to the laterally varying permafrost thickness in the near subsurface from the mainland and , across Harrison Bay. This response is manifested by high quality reflection continuity onshore where permafrost thickness is at a maximum; in contrast to the shallow offshore areas of Harrison Bay where reflection quality degrades laterally due to permafrost deterioration. This differential thinning is caused by the influx of relatively warm sea water since the latest Holocene sea level transgression. Resultant permafrost thinning within Harrison Bay has been recorded to as little as 683 ft in the East Harrison Bay # 1 well. The velocity effect seen in the seismic data is a pronounced broad "pull-down" of reflection time coincident with the coastline. Conversely seismic reflections show a uniform "pull-up" directly beneath the shoreline indicating permafrost thickening as you move back onshore, as evidenced by the 1563 ft thick permafrost layer in the West Sak #16 well. Interpretation of all available seismic and well log data translates to an expected permafrost thickness of 900 ft and an anticipated permafrost base at the Oooguruk # 1 location of approximately -975 ft to -925 ft subsea. The nearest offset well, the Thetis Island # 1 (1.75 miles north northeast), base of permafrost is interpreted to be at -660 ft subsea. This well is the nearest direct offset and represents the best geographic analog for anticipated permafrost thickness and levels from an offshore ice pad. Shallow Gas/Oil Accumulations There is no geophysical evidence for any significant accumulations of shallow gas beneath the Oooguruk #1 location. No amplitude anomalies, velocity sag or frequency attenuation indicators are present from 3-D seismic covering the location. There is an interpreted gas hydrates layer beneath the permafrost that has been penetrated by exploration wells surrounding the location. On mudlogs, elevated gas readings through C5 were recorded on the chromatograph, but gas amounts through the hydrates layer never reached levels in any of the offset wells that presented any drilling hazards in the operations of these wells. Specifically, the Kalubik #1 and East Harrison Bay #1 were both drilled in areas of indicated higher hydrates concentration from the 3-D (higher amplitude response), but neither well encountered any significant amounts of gas or experienced any notable drilling operational issues. Hydrates thicknesses were interpreted in the Kalubik #1 (460 ft thick, hydrates base -1617 subsea) and Thetis Island #1 (450 ft thick, base hydrates -1516 subsea) and should be present in the Oooguruk #1 at a thickness of 540 ft and an interpreted base of hydrates at -1540 subsea. For the purposes of well planning a partial gas hydrates and free gas column was planned for in our well design and subsequent drilling operational plan development. Having noted the interpreted hydrates layer, there are no other velocity density indicators of any significant free gas beneath the well. Two minimal faults are revealed in the CDP reflection data within 2000 feet of the well; however they terminate at a minimum depth of -6,000' subsea and are not the likely source for the shallow gas hydrates noted in the offset wells. However, CDP reflection data also reveal several listric normal faults southwest and northeast of this well. These faults are interpreted to extend into the shallow sedimentary , section and are the most likely migration pathways for minor shallow gas/hydrates accumulations seen at the base of permafrost. Minor elevated background gas within the permafrost interval is anticipated and planned for in the proposed Oooguruk # 1 well. The Ugnu-West Sak sand interval is present in the East Harrison Bay #1 (2,220' to 3340' MD, -2187' to -3,307 subsea), Kalubik #1 (2220 to 2990 MD, -1881 to -2957 subsea), and Palm 3W-07 (2675 to 3265 MD, -2152 to -2425 subsea). Minor background gas and no oil shows are seen in association with these sands. This is consistent with the known limit ofUgnu and West Sak oil bearing sands to southeast in the Kuparuk River Unit. This interval or its' equivalent, is anticipated to occur at a depth ranging from approximately -2100 to -3250 subsea in the Oooguruk well and any sands present will most likely be water bearing or contain only minor accumulations of solution gas. The previously referenced vertical pressur~ profile, which incorporates all pertinent engineering, geological and geophysical data, served as the basis for design and development of all operational and safety plans for the Oooguruk # 1 well. Summary As a result of this shallow hazards interpretation, we have not identified from seismic or surrounding offset well data any conditions beneath the Oooguruk # 1 location, which could pose a prohibitive shallow or intermediate depth drilling hazard to the planned drilling operations. A copy of all pertinent data to shallow geological and drilling safety conditions has been supplied to operations and engineering personnel in the preparation of the Oooguruk # 1 well design and operational plan. /7 ~~ /" / M¡X. Furin Yice President of Geoscience November 14,2002 Well Site Survey Abnormal Formation Pressure Evaluation State Lease ADL 389954 WELL SITE SURVEY ABNORMAL FORMATION PRESSURE EVALUATION OOOGURUK #1 LOCATION ALASKA STATE LEASE ADL389954 HARRISON BAY, ALASKA Pursuant to 20AAC 25.033 (e) (1) .available geophysical data and proximal offset well data have been examined and evaluated for potential overpressure strata. Examination and interpretation of these data suggest that formation pore pressure increases at a normal gradient with depth and abnormal formation pressure is not anticipated to the proposed total depth of7,500'. Reference is hereby made to the proposed Oooguruk #1 seismic/well base rp.ap, 3-D seismic reflection profiles and the interval velocity/pressure gradient exhibit previously submitted to the DNR Oil and Gas Conservation Commission November 2002. The seismic/well base map highlights the area of 3 - D coverage, 2-D coverage, attached reference seismic lines, the locations of all key offset wells proximal to the Oooguruk # 1 well location. The referenced pressure/interval velocity exhibit integrates all available geologic, petrophysical, engineering and geophysical information used in our abnormal pressure analysis for the Oooguruk # 1. The exhibit has two plots imbedded in it which display interval velocity and formation pressure on the corresponding "x" axis versus a common increasing depth scale on the "y" axis. Examination of all available velocity, density and pressure data show a general increase of interval velocity and pressure with depth to the limit of penetrated formations below 9800 ft within the area. Short discrete velocity reductions on an overall increasing trend are observed and are interpreted to represent local variations in formation density, velocity, and lithology. No correlative velocity reversal, "breakback", or "flattening" is observed that could be related to overpressure within any formations above the proposed total depth of 7500 ft. This overpressure evaluation is supported by all seismic and offsetting exploratory well data. The key offset wells for planning purposes are highlighted on the aforementioned seismic/well base map. These wells are: Arco-Kalubik #1, Arco-Kalubik #3, Unocal- East Harrison Bay # 1, Exxon-Thetis Island # 1, Arco- Palm 3 W -07, and Arco- West Sak #16. The total depth of these wells ranged from 6166 ft to 9809 ft TVD. All six of these wells were drilled with maximum mud weights ranging from 9.5 ppg to 10.6 ppg. As it is general practice to drill slightly overbalanced, in situ pore pressures are likely less. Bottom-hole formation pressure data collected in these wells from within the Ivishak and Lisbourne Formations show a range of equivalent mud weights from 9.3 ppg to 9.6 ppg, which represent a normal pressure gradient to depths greater than 8000'MD. 1 Well Site Survey Abnormal Formotion Pressure Evaluation State Lease ADL 389954 In summary, abnormal formation pressure is not anticipated at the proposed Oooguruk # 1.

Oooguruk #1 is located offshore west of Oliktok Point and south-southwest of Thetis Island on the North Slope of Alaska. The well was drilled as a straight hole with a 9 7/8" bit to surface casing at 3010' MD and 6 %" hole size to TO at 6900' MD. Clays washing out were a minor problem before surface casing was set. The hole packed off with clays and circulation was briefly lost at 3898' MD and 5129' after making connections. In both cases, slow backreaming of two stands while slowly bringing the pumps back up, then pumping sweeps, corrected the problem. No other significant drilling problems were encountered. The targets of interest for this well were the Middle Brookian, Torok, Kuparuk "C", and Nuiqsut Sand. The Middle Brookian did not yield any more than a trace of sand in cuttings samples, however, C1 through C5 were present with a high gas value of 261 u at 4530' MD. The Torok target yielded moderate gas and a modest show in samples, but only trace sand and abundant siltstone. Maximum gas was 484u at 5394' MD with the following chromatography in ppm: C1 89516, C2 5097, C3 2134, C4 907, C5345. ( The next significant hydrocarbon show was encountered at 6250' to 6263' MD. This was a thin section of the Kuparuk "C" sand. Maximum gas was 664u at 6258' MD with the following chromatography in ppm: C1 92570, C26639, C3 3867, C4 1785, C5 929. Samples yielded 100% moderate intensity yellow-gold sample fluorescence; very fast moderate intensity light yellow cut fluorescence; none to pale straw visible cut; none to faint light tan residual ring; and moderate intensity light yellow to pale orange residual ring fluorescence. A good show was encountered from 6530' to 6620' MD in the Nuiqsut / Nechelik Sands. Maximum gas was 816u at 6538' MD with the following chromatography in ppm: C 1 127068, C2 9328, C3 5414, C4 2511, C5 1124. Samples yielded 100% moderate intensity yellow-gold to orange sample fluorescence; instant moderate intensity bright yellow to white cut; pale straw to straw visible cut; medium to dark brown residual ring; and very bright yellow to yellow orange residual ring fluorescence. There was moderate hydrocarbon odor, oily sheen, and free oil in the mud at the shakers. The well reached a total depth of 6900' MD on March 21, 2003. Epoch Well Services provided RIGWA TCH 2000™ Drilling Monitoring services and DML TM Mudlogging Service.
