The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all, other required permitting determinations are made. 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. Annular disposal has not been requested as part of the Permit to Drill application for Sakonowyak River Unit #1. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

ILX Drilling - Sak River #1 Well Plan .Drillina Hazards Shallow Gas Shallow Gas is not expected. Offset wells show no indications of shallow gas. Seismic analysis using seismic stacking velocities also show no indications of shallow gas. A full explanation of the seismic work is attached. Hvdrates Hydrates are not expected. Offset wells show no indications of gas hydrates. GPB Aurora S-Pad (located 4.8 miles to the SW) has encountered some gas hydrates. Several wells have reported gas cut mud while drilling below the base of the permafrost. Standardized gas hydrate drilling practices have minimized the impact to overall operations. Sak River mud returns will be monitored to determine if hydrates are encountered on this well. In the event of encountering gas hydrates, the GPB S-Pad Aurora gas hydrate drilling procedures will be undertaken. Abnormal Pressures Abnormally pressured zones are not expected. The pore pressure gradient is estimated to be 9.0 ppg EMW from surface to the base of the HRZ. From the base of the HRZ to TD the gradient is expected to be 9.6 ppg EMW. This pore pressure profile is based on review of offset exploration wells Gwydyr Bay State Unit #1, Gwydyr Bay State A #1, Long Insland #1, Gwydyr Bay South #1, and West Gwydyr #1. All 5 exploration wells showed no signs of well flows or well kicks. Kuparuk development wells drilled from GPB Aurora S-Pad were also reviewed. Current Kuparuk BHP's range from 6.9 to 9.6 ppg EMW. Pore pressure predictions were also made utilizing localized 3D seismic stacking velocities and sonic log interval transit times. This analysis shows a normal pressure gradient with no evidence of abnormally pressured zones. A full explanation of the seismic work is attached. Hvdroaen Sulfide The six offset wells listed below were reviewed for potential exposure to H2S. Of these six wells, none reported evidence of H2S during drilling (see Table below). GPB Aurora S-Pad development wells (Kuparuk Formation) were also reviewed for H2S. The latest readings from producing wells show an H2S level of 8 ppm from one well. PVT analysis of GPB Aurora S-Pad crude shows negligible H2S content. H2S is not anticipated during the drilling of Sak River #1, however Standard Operating Procedures for H2S detection will be in place on the rigsite and H2S precautions will be observed at all times. BPXA has not included an H2S contingency plan with this Application and requests an exemption from the H2S requirements found in 20 AAC 25.065. subpart (c).

MD Intersect TVD Intersect Estimated Throw Throw Direction 3377' 2843' <50' West Stuck Pipe In the surface hole, gravel sections and unconsolidated intervals may cause hole cleaning problems. Mud properties will be adjusted accordingly to clean the hole. Lower in the surface hole, SV sands can pose differential sticking problems. Again mud properties will be adjusted accordingly. In the production hole, potential shale instability in the HRZ poses the main stuck pipe mechanism. Established shale drilling Recommended Practices will be observed to minimize the risk of stuck pipe: mud weights may be raised, mud properties adjusted, and shale inhibition added.

Final packer setting depth (to be determined from log data) will be set 200' above the uppermost interval that may be production tested. See attached completion schematic. The well will be perforated and flow tested after the drilling rig has moved off. Well TestinQ This exploratory well targets one prospective producing interval, the Kuparuk C sands. Well testing will utilize a portable test separator, flare and portable tank battery. The tank battery will be bermed to contain 110% of the tank battery volume. Total estimated well test duration is 7-10 days. If the well will not flow to surface on it's own, Nitrogen will be used to "kick off" the well. If the interval is capable of producing >500 bopd, the well test will continue as planned. If the well is incapable of producing >500 bopd, the interval will be stimulated with a hydraulic fracture treatment. Following the fracture stimulation, the well will be flowed clean, and then tested as planned. Surface samples will be collected from the test separator periodically during any flow test. Any produced liquids brought to surface will be either collected and hauled to an existing facility in Prudhoe Bay or Milne Point or the fluids will be re-injected back into the producing formation. Any produced gas brought to the surface will be flared. Abandonment/Suspension In the event the well cannot be tested during the current drilling season, it will be suspended in a manner consistent with the AOGCC requirements. If the decision is made to abandon the well, it will be abandoned in a manner consistent with AOGCC requirements. If the flow testing is successful, the well will be suspended in a manner consistent with the AOGCC requirements and later used in field development operations. 9 (' ILX Drilling - Sak River #1 Well Plan Sak River #1 Summary of Drilling Hazards POST THIS NOTICE IN THE RIG FLOOR DOGHOUSE 1. No Abnormal Pressures are anticipated. 2. No Shallow Gas is expected. 3. Gas Hydrates are not expected. However, Standard Gas Hydrate drilling procedures will be followed in the surface hole. 4. H2S is not expected. Standard Operating procedures for H2S detection will be in place on the rigsite and H2S precautions will be observed at all times. Note wind direction and Muster areas at the beginning of each tour and any time changes are observed/made. 5. Lost Circulation is not expected. LC Material will be on location at all times. 6. One Fault will be crossed in the surface hole. Lost Circulation is not expected. 7. Stuck Pipe risk will be low to moderate while in the SV sands due to differential sticking, while in the Ugnu due to coal intervals, and while in the HRZ due to shale instability. 8. Coal Sections may be encountered in the Upper and Lower Ugnu. 9. There are no Close Approach issues. 10. Potential hyrdrocarbon bearing intervals are: Ugnu Top 5376' MD/4132' TVD Schrader Top 8279' MD/6003' TVD Kuparuk Top 11841 'MD/8463' TVD Consult the final well plan for additional information 10 (.

With regard to the cement amount, the convention I am familiar with has the same cement volume throughout the permit paperwork. In your case I would have expected to see the 206 sx on the face of the permit. Good news on the consistency review. You aré correct with regard to the regulation on casing test pressure. Personally I don't like the way that is stated, since 500/0 of the rating of the BOP doesn't necessarily have anything to do with the pressure design of the casing string. I guess I look at our requirement as a minimum. The way you stated the planned casing test pressure was different than I have seen before. You are correct in testing to the calculated MASP at a minimum. Some of the other permit applications I have seen test to 4000 or higher if a stimulation is 10f2 1/1810211:03AM RE: Sak River Permit f possible. You might check with the gUys drilling on S or L pad and see what , they do. I know stimulations have been performed on S. Thanks for the clarification on the downhole jewelry. Not really critical, but there was a discrepancy between the text and drawing. Again, thanks for the response. Have you started packing the ice road/trail yet?? When do you anticipate spud??

Chet Paris and Odd Fuglestad (BP Exploration Alaska Inc.) Drilling Hazard and Risk analysis of the Sak River No.1 well December 6, 2001 Steve, This letter documents BPXA's drilling hazard and risk analysis for the proposed Sak River No.1 well scheduled to spud January, February, or early March of 2002. The analyses of both the 3D seismic data and the offset well show no indications of drilling hazards or risks. The analyses of this data are not definitive, therefore, BP Exploration will work on the assumption that the possibility of encountering drilling hazards exist and establish processes to mitigate the associated risks. As usual, BPXA make every attempt to conduct our drilling operations in a safe and environmentally responsive manner. In our drilling hazard and risk analysis of this well we used our interpretation of the 3D seismic data obtained over the well location, the data collected from the nearby wells, which include the Cities Gwydyr Bay State A-01 (6,500' from BHL), the Mobil Gwydyr Bay State Unit-01 (14,000' from BHL), the Conoco Gwydyr Bay State-01 (15,000' from BHL), the Mobil Gwydyr Bay South (15,000' from the BHL), Amerada Hess Northstar-03 (16,000' from the BHL) and the Sohio Long Island-01 (20,000' from the BHL), along with field data from the Northstar Field (4 miles northeast from the BHL), the Aurora Field (4 miles south of the BHL), and the Milne Pt. K pad development (9 miles west of the BHL). The following is a summary of our analysis of the potential hazards and risks of drilling the Sak River #1 well: . Our analysis of the nearby wells and oil fields indicates that the risk of encountering gas hydrates in this well is low. As shown in the nearby Milne Pt. Field oil field, gas hydrates are not detectable with conventional seismic data due to their composition. The mud and wireline logs from the nearby wells give no clear indication of gas hydrates. Maps published by the USGS indicate that the Sak River well location is northeast of the Eileen gas hydrate accumulation. BP has documented to the AOGCC that there are no gas hydrates in the Northstar field which is in a similar geological setting to Sak River #1. . Interpretation of the 3D seismic data and the data from the nearby wells indicate a low probability of encountering significant shallow gas in the Sak River #1 well. The brightest amplitudes observed in the 3D data are at the SV4 and SV6levels and appear to be due to stratigraphic variations and not gas. The mud log data from the nearby wells have only a few weak gas shows in the Sagavanirktok and U gnu Formations due to low concentrations of gas in water and coal gas. The wireline logs from the nearby wells indicate no gas sands but several coal gas intervals, the thickest being a 20' section in the Long Island-01 well below -4,289' TVDss. This analysis agrees with the more extensive shallow gas analysis of the Northstar Field presented to the AOGCC. . Interpretation of the 3D seismic data indicates that the proposed Sak River #1 borehole crosses only one small north-south trending fault « 50') at approximately -2,800' TVDss that dips to the west. . Analysis of the 3D seismic data and the nearby well data indicate that the Sale River #1 well will penetrate a normally pressured section to its final TD. The geopressure gradient that the Sale River #1 well will encounter was estimated using the sonic log interval transit times and mud weights from the nearby wells and the 3D seismic stacking velocities along the planned well path. Well plots of the sonic transit times from the nearby wells indicate that the shales show a normally pressured, hydrostatic gradient through the TD of the well just below the Kuparuk interval. The notable deviations are the organic-rich basal Brookian and HRZ shales which are lower velocity due to their composition. The mud weights from the nearby wells also indicate that the Sale River #1 well will encounter a normally pressured section. Most of the mud weights range between 9 ppg and 10 ppg, with none exceeding 10.5 ppg. The seismic stacking velocities along the Sale River #1 well path also follow a hydrostatic gradient and correspond to the nearby checks hot surveys but with a lower resolution. Please contact either Chet Paris at 907-564-4219 or Bill Bredar at 907-564-5348 if you would like a presentation regarding our analysis of the hazards and risks of drilling the Sale River #1 well or if you have any questions or further issues regarding this well.

Hydrates have normally appeared below the base of the permafrost, typically at a depth of 2000-2300 ftss but may be present as deep as 3000 ftss. Free gas occurs below the hydrates. The closest wells, surrounding the Sak River-01 well, GwydyrA-01, Gwydyr-01, GwydyrS-Ol and GwydyrU-Ol appear not to have any of these problems (1.5 - 3 miles away). Hydrates/shallow gas from seismic Due to its composition, hydrates are not detectable on conventional seismic. Only the free gas below the hydrates can be seen in the Milne area. Thus for the Sak River-01 well only the risk for shallow gas can be assessed using seismic data. In general the seismic data is focused to image deeper targets and are noisy in the upper 400 msec due to low fold and permafrost. Base permafrost, which is the most likely seal of potential shallow gas, is poorly imaged on seismic due to its transitional character. Sak River-Ol Figure 1 shows the shallow section of the planed Sak River-01 on Fullsail 3D line 1214. The most likely position of base permafrost is shown. These correspond to a permafrost thickness of around 1500 ft in the well (12000ft/s velocity). The two brightest horizons below base permafrost, Intra SV6 and Top SV4, have been interpreted to get an idea about potential traps and amplitude variation. The well will penetrate a fault at 520 ms, corresponding to around 3000 ft. Figure 2 shows a TWT structure map of horizon Intra SV6 (location of seismic line in figure 1 is indicated). Potential truncation with the base permafrost is shown in white. The twt contours are generally parallel to the truncation line, indicating no local trap around the Sak River-Ol well. A larger trap might exist, but then GwydyrS-Ol seams to already have penetrated it. Figure 3 is an amplitude trough map of the interpreted Intra SV6 horizon. A weak amplitude anomaly is shown in red around the Sak River-O 1 well. The nearby wells show the SV6 interval to comprise of fluvial sediments, on the contrary to the deeper SVl-SV5 sequences which are marine in origin. The anomaly probably represents a slightly sandier channel facies then seen in surrounding wells. Although very unlikely, the channel ( feature could contain shallow gas trapped against the permafrost to the southwest. The depth of this interval is around base permafrost, 1500-1800 ft. Figure 4 shows a TWT structure map of horizon Top SV 4 (location of seismic line in figure 1 is indicated). This horizon truncates the permafrost outside the map area (around the Cascade-01 well) and no trap is evident around the Sak River-01 well. Figure 5 is an amplitude peak map of the interpreted Top SV 4. High amplitudes (red color) are evident in the Sak River well but also in GwydyrA-01 and Gwydyr-Ol. Conclusion Presence of gas hydrates cannot be evaluated from seismic data. Presence of shallow gas in the 0-3000 ft section of the Sak River-Ol well is considered low, but cannot be completely ruled out. Highest potential seams to be related to mapped Intra SV6 horizon, just below the permafrost from 1500 to 1800 ft. The risk is considered low since no robust trap has been identified and the weak amplitude anomaly has the character of lateral lithology variation rather then shallow gas.

INTRODUCTION AND BACKGROUND On June 1, 2001, A VCG LLC (A VCG) filed the Sakonowyak River Unit application (Application) with the Division of Oil and Gas (Division) on behalf of BP Exploration (Alaska) Inc. (BPXA), the designated unit operator. The proposed unit is located in Gwydyr Bay Alaska, at the mouth of the Sakonowyak River, south of the Northstar Unit and north of the Prudhoe Bay Unit. The proposed unit area covers approximately 11,520 acres within five individual State of Alaska oil and gas leases. A VCG submitted the Application for approval by the State of Alaska, Department of Natural Resources (DNR). Approval of the proposed Unit Agreement (Agreement) would confonn and modify the lease contracts to be consistent with the Agreement. tv ~ / . r:/I- /...ð., ~ Four of the leas~.as in the proposed unit area were offered in Sta!i of AJaska L~ Sale 80)íéld on December 5, ~~ DNR issued oil and gas leases ADL 38519'8, ADL 385i§9~ADL 385201, and ADL 375202~ effective February 1, 1996, on State of Alaska lease fonn number DOG 9208. The seven-year primary lease tenn of these leases expires on January 31, 2003. The remaining lease in the proposed unit area was offered in State of Alaska Lease Sale 65, held on June 4, 1991. DNR issued ADL 377051, effective August 1, 1991, on State of Alaska lease fonn number DNR 10-4037 (Revised September, 1990), which provides for a ten-year primary tenn. Without unitization, lease ADL 377051 expires July 31, 2001. BPXA initially purchased the four Sale 80 leases, and then assigned 25% of the working interest in each to Arco (Alaska), Inc. (AAI). AAI changed its name to Phillips (Alaska), Inc. (PAl) effective Apri127, 2000. Earlier this year, PAl assigned its 25% working interest in the leases to A VCG. ADL 377051 was originally issued to AAI in Sale 65. Less than a year hter, AAI assigned Phillips Petroleum Company and Texaco Exploration Alaska each a one-tlllrd working interest in the lease. AAI late~".,~./"_"~"-"----'" assigned an 81/3% working interest ownership in the lease to Exxon Corporation, thus retaining a 28% I . Z ~ -0 ''Z- working interest. h December 2000, Texaco Explomtion Alaska assigned its wotking in+ to /d .':f; Phillips Petroleum Company, which became the property of PAl following the BP-ARCO fner~ 'cJ ~ \ Earlier this year, Exxon Corporation agreed to assign its working interest in the lease to A V~,. and W Phillips Petroleum Company has agreed to do the same for its working interest in the propos unit. / Upon approval of these pending assignments, BPXA and A VCG will have 62% and 38%) effec' ~ .--- working interests in the unit area, respectively. The Agreement, if approved, will extend the tenn of the leases for as long as they are subject to the Agreement. 11 AAC 83.190. II. APPLICATION FOR THE FORMATION OF THE SAKONOWYAK RIVER UNIT A VCG submitted the Application on June 1, 2001, and simultaneously paid the $5,000.00 unit application filing fee, in accordance with 11 AAC 83.306 and 11 AAC 05.010 (a)(10)(D), respectively. The Application includes: the Agreement; Exhibit A legally describing the proposed unit area, its leases, and ownership interest; Exhibit B, a map of the proposed unit; and Exhibit G, the proposed Plan of Exploration (Initial POE).
