As the attached AOGCC Diverter Systems Inspection Report shows the system function tested and was installed properly. I requested that an additional 20' of line be added to the vent line to get the end farther away for the rig. This was being done as I departed the location. Summary: i witnessed the diverter test and inspected the system for correct installation. The system was installed properly, with the exception of line length which was corrected, and tested OK.

A drilling permit is not valid at a location where the applicant does not have a fight to drill for, produce, and remove oil and gas. This approval is expressly conditioned upon conformance with the operating agreement in effect between BP Exploration (Alaska) Inc., and the owners of ADL 355016, Maxus Exploration Company and Amerada Hess Corporation, and not on the proposed total depth of the well as represented on the enclosed form 10-40 I. Any penetration of strata in the North Milne Point No. 1 well, for which BP Exploration (Alaska) Inc. has not been designated operator, will be a violation of this approval. 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. 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 wimess the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

In the event commercial hydrocarbons are not found, the well will be P&Aed as per North Milne Point #1 Dry Hole P&A Diagram and Proposed Summary of Operations-- see Attachment Nos. 1 and 2, respectively. The reason of abandonment in this circumstance is obvious. el) If the well finds commercial hydrocarbons, BP proposes to P&A/Suspend the well according to North Milne Point #1 P&A/Suspend Diagram and Proposed Summary of Operations -- see Attachment Nos. 3 and 4, respectively. The reason to P&A/Suspend this appraisal well in this circumstance is to prevent damage to the tree from ice encroachment onto Levitt Island while BP further evaluates the reservoir and facility designs alternatives. The P&A/Suspend proposal suggests a design that would both meet suspension and P&A criteria through the use of an FMC mudline suspension system (SD-l). This is a win/win approach whereby the well is still accessible in future years should BP decide and receive approval to construct a facility in this location. In the event the decision is reached or approval is not granted to construct a facility at this location, then the well would already meet P&A status eliminating the need to spend future moneys on access and further P&A operations. e2A) Porous and Abnormally GeoPressured Strata: The Schrader Bluff Sands which are expected to be wet and are normally prelssured at 8.6 Ppg will come in with the Na Top prognosed at 4200' sstvd and thelOB Base at 4600' sstvd. The primary target is the Kuparuk Sands which are prognosed at 9.6 ppg (based on MPF-38 Kuparuk intercept in the same fault block). The top prognosed sand is the C Sand at 7684' sstvd and the base sand will be the A1 at 7795' sstvd. · There are no other porous or abnormally pressured sands expected. e2B) The kind, size, and location, by measured depth of proposed of proposed plugs is depicted on the P&A diagrams. e2C) There are no plans to perforate or perform well tests for this well.

Please find the attached request for Permit to Drill the North Milne Point #1 Well. Similar to NMP#2 well, BP is handling this as an exploration well for permitting purposes. It is actually an appraisal well in regard to geology, geopressures, and engineering. It is being drilled from the Levitt Island to a BHL which lies in the same stratagraphic structure from which the Milne Point F Pad wells are currently producing from. In fact, the North Milne Point #1 well will intercept the Kuparuk reservoir down dip in the same fault block the MPF- 38 well recently drilled into. The intent of this well is to determine if there is an oil/water contact associated with this fault block. There are no plans to core or perform a flow test on this well. SUMMARY: Casing Design- Variance is requested to 20AAC25.030 Section (1) structural casing must be set by driving, jetting, or drilling to minimum depth of 100 feet below the mud line. (2) conductor casing must be set at least 300 feet, but not more than 1000 feet, below the mud line; the casing must cemented with a quantity of cement sufficient to fill the annular space up to the mud line or to the top of the casing when the blowout prevention stack is placed in an excavation or glory hole. Cement fill must be verified by observation or-other means approved by the commission. Upon approval of the commission, cement may be washed out to a depth not exceeding the depth of the structural casing shoe, to facilitate casing removal upon well abandonment. BP submits proposal to eliminate the structural casing and set a conductor casing 100' below the mudline. Since this well is in the expanded Milne Point Unit and BP is confident that we have sufficient offset data and seismic data to eliminate the chances of shallow gas and abnormal geopressures, we are submitting a standard Milne Point casing design which is the Ultra Slimhole 9-5/8" surface casing and 7" Iongstring into the Kuparuk reservoir. We are proposing to set 20" conductor pipe +_100' below the mudline as was done by Conoco on the Northwest Milne Point #1 well and the NMP#2 currently being drilled. The 9-5/8" surface Casing is proposed for a deep set below the Schrader Bluff Sands into the Seabee Shale. This is the standard practice in the both the Milne Point and Kuparuk Units. Furthermore, the Schrader Bluff sands are wet in the Northwest Milne Point well and in all the wells drilled north of the Milne Point F and L Pads -- the northern portion of the Milne Point Unit lies within the water leg of the Schrader Bluff structure. The 7" casing will then be run as a long string across the Kuparuk reservoir into the rathole in the Miluveach Shale. A detailed casing design is included in the permit package. Spacing and Deviation Exceptions: There should not be any Spacing or Deviation Exceptions required for this well. As stated, the North Milne Point #1 well will drill to a bottom hole location of 2009 FSL and 1017 FEL Section 18 Township 14 North and Range 10 East. This BHL lies within the expanded Milne Point Unit boundary for which the operators are BPE&O 64.38, BPX 26.81, and OXY USA 8.81 down to 7526' sstvd. The 7526' md boundary is a stratagraphic reference to the rathole drilled into the Miluveach Sand below the Kuparuk reservoir in the Northwest Milne Point #1 well-- the 7526' md equates to a tvd depth 241'tvd below the top of the Miluveach Shale. The proposed TD in the NMP#1 well is 230' tvd below the top of the Miluveach Shale and Logging While Drilling tools will be used to ensure we do not drill beyond this datum (which has an 11' tvd safety factor included). Also, the geological prognosis shows no faults present at TD. The operators for strata below 7526' are Maxus 50.00 and Amerada Hess 50.00. Conoco negotiated a Farmout Agreement between Maxus Exploration Company and Amerada Hess Corporation pertaining to the State of Alaska Leases to include 355016, 355017, and 335018. Conoco earned designation as Operator as per that agreement by drilling the Northwest Milne Point #1 well. The farmors (Maxus and Amerada Hess) now have overriding royalty interests as per the Farmout Agreement. BP assumes all rights as Farmee in this agreement. A P&A/Suspension proposal is included in the permit package. Please call me should you have any questions -- 564-5713.

Approval is requested for Annular Pumping into the NMP#1, 9-5/8" x 7" casing annulus. 2. The base of the Permafrost for all wells located in the Milne Point Unit is +_1,850' TVD. Aquifers in the Milne Point Unit have been exempted from Class II injection activities by the AOGCC by Aquifer Exemption Order #2 as referenced in Area Injection Order #10. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 9-5/8" casing shoe will be set at 5102' md (4756' tvd) which is a minimum of 500' tvd below the Permafrost and into the Seabee/Colville formation which has an established history of annular pumping at Milne Point. 4. There are no domestic or industrial water use wells located within one mile of the project area. 5. The wastes to be disposed of during drilling operations can be defined as "DRILLING WASTES". 6. The burst rating (80%) for the 9-5/8" 40# L80 casing is 4600 p$ig while the collapse rating (80%) of the 7" 29# L80 casing is 5616 psig. The break down pressure of the Schrader Bluff formation is 12.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping regardless of fluid density is 2000 psi as per Shared Services Drilling "Recommended Cuttings Injection Procedure". 7. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. 8. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.

GENERAL DISCUSSION -- North Milne Point #1 Objective: The North Milne Point #1 well is planned as an appraisal well into the MPF-38 fault block. The geological prognosis includes the Kuparuk C, B, A3, A2, and A1 Kuparuk sands. The primary target is the KUPARUK 'A' Sands with additional potential in overlying 'B' and 'C' sands. it is hoped a full oil column will be found; however, an Oil/Water contact could be encountered. If the well encounters commercial hydrocarbons, the well will be suspended utilizing an FMC SD-1 mudline suspension system as per the attached 10-403 request. Otherwise, the 8.5" open hole section will be plugged and the wellbore abandoned as per 20 ACC 25.105. Drilling Hazards and Risks: The Kuparuk reservoir sands are expected to be a maximum of 3853 psig or 9.6 ppg. The closest well is MPF-38 which was recently drilled by Nabors Rig# 27E. Obtain the MPF-38 work file from Nabors Rig# 27E and review same. This well is expected to drill very much like the development wells currently drilled in the Milne Point Unit; however, this well is located on the north most edge of the Milne Point Unit boundary and the unexpected may happen -- BE 'ALERT!!!!!!!!!!!!!!!!! There will be no close approach wells associated with the drilling of the North Milne Point #1 well. An IN-HOLE REFERENCE GYRO will NOT be required for this well. Lost Circulation' The MPF-38 did experience losses due to what has been termed the breathing phenomena. The well takes fluid and then gives some of it back for instance when the pumps are shut down. The recent efforts by Nabors 27E to combat this problem have been to drill to TD with a 9.9 ppg MW versus the standard 10.2 ppg previously used in Kuparuk wells -- the MW is increased as required to drill the Kuparuk interval. Lost returns while running and cementing the 7" production casing in this portion of the Milhe Point Unit is quite common. A lost circulation zone has been verified to exist in what are called the Colville sands which are sometimes encountered at or near the base of the Coiville Shale formation near the top of the HRZ. Have the LCM materials outlined in the Drilling Fluid Program on location and recommended pills ready to address the Lost Circulation Problem when drilling into the Kuparuk Sand. Stuck Pipe Potential: The F Pad Data Sheet prepared by Pete Van Dusen will be utilized to drill this well. There was one stuck pipe incident on MPF-53 in the surface hole when running gravels were encountered, The immediate reaction to combat running gravels is to immediately raise the Funnel Viscosity to 150 seconds/quart. There were three stuck pipe incidents on L Pad and one while drilling the No. Point #1 exploration well-- these incidents have been and can continue-to be avoided by ensuring good hole cleaning and short tripping techniques. Gas hydrates: Although hydrates were encountered on E, H, and I Pads located in the southern portion of the Milne Point Unit, no hydrates have been encountered while drilling the J, C, L, or F Pads which are located in the northern portion of the unit -- NO HYDRATES ARE EXPECTED WHILE DRILLING THIS WELL WHICH IS LOCATED IN THE UNIT'S NORTHERN PORTION. Neither the Northwest Milne Point #1 and Arno Jones Island #1 wells experienced hydrates. No other drilling hazards or risks have been identified for this well. Hydrogen Sulfide-- H2S (20 AAC 25.065) There is no evidence of H2S being encountered in any of the offset wells. Specifically, The Proposed North Milne Point #1 Kuparuk target is located 1.5 miles northeast along a 23° azimuth from where the recently drilled MPF-38 well penetrated the Kuparuk reservoir -- these Kuparuk targets are in the same fault block and the MPF-38 well did not experience any signs of H2S. The surface location for the proposed North Milne Point #1 well is located only 2.5 miles northeast along an azimuth of 40° from the surface location of the Northwest Milne Point #1 Exploration well -- Mud logs from this well indicate no presence of H2S. The nearby Arco Jones Island #1 Exploration well was drilled with no sign of H2S. Furthermore, in reference to Arco's permit to drill the Jones Island #1 Exploration well, research was conducted for the following exploration wells for which there was no evidence of H2S at any of these wells: Sand Piper #1 Well Long Island #1 Well Phlagm Beechey Point Well Seal Island Wells (four) Northstar Wells Since nearby offset well data indicates H2S is not present in any of the formations to be drilled in the North Milne Point #1 well, Shared Services Drilling asks for exemption from items c2B, c2C, and c3 in 20 ACC 25.065 and plans to comply with the following items: clA) clB) clC) c2A) c2D) The mudlogging unit will be equipped with a combination visual and audible alarm system located where it can be seen or head form all parts of the location; The automatic hydrogen sulfide monitor will have a minimum of two probes, one at the shale shaker and one at the bell nipple; and In addition to the automatic hydrogen sulfide monitor, at least three manual detectors will be available at the rig site -- if the manual detectors require tubes, an adequate supply of detector tubes will be available at the rig site. As stated, we do not expect to encounter H2S. In the unlikely event H2S were encountered, the effects would be minimal for the following reasons: · Since our seismic analysis does not indicate any abnormal pore pressure and our MW program is consistent with the offset wells, H2S would be encountered in an overbalance situation and effects would be minimized. · Upon detection, adequate supplies of Caustic Soda are maintained at the rig site to initiate treatments. · Furthermore, since this location is not remote, Baroid could provide adequate supplies of Zinc Carbonate from the mud plant inventory to treat the mud. Furthermore, the Nabors 22E Rig is equipped with six Scott Air-Packs available at the rig floor as standard equipment. All personnel on location are trained in H2S and the use of Self Contained Breathing Apparatus. NORTH MILNE POINT #1 WELL WELL SITE SURVEY and PRESSURE ANALYSIS (20 ACC 25.005c8 and 20AAC 25.061a and c) Site-specific seismic data and offset well information have been utilized to perform a pressure analysis for the drilling of this well. The North Milne #1 Well will TD 300' md past the base of the Kuparuk reservoir into the Miluveach Shale formation -- planned total measured depth is 9204' (8038' sstvd). The seismic data indicates that no abnormally pressured zones should be encountered while drilling the North Milne Point Cf1 well-- see the Attached 2D Seismic Shallow Hazard Assessment prepared by BPX geophysicist Eric Dixon complete with three ITT vs Depth Charts numbered 14, 15, and 16. Based on these results and the absence of shallow gas or abnormally pressured zones in nearby offset wells, we do not feel a shallow hazard survey is necessary. The proposed North Milne Point #1 Kuparuk target is located 1.5 miles northeast along a 23° azimuth from where the recently drilled MPF-38 well penetrated the Kuparuk reservoir-- these Kuparuk targets are in the same fault block and the MPF-38 well did not experience any signs of H2S. The surface location for the proposed North Milne Point cf1 well is located only 2.5 miles northeast along an azimuth of 40° from the surface location for the Northwest Milne Point cf1 Exploration well-- See Attachment No. 3 for a MW vs TVD plot. Again, all these wells showed no signs of abnormal geopressure. BP EXPLORATION Memorandum To: From: Subjeot: Tim $chofield Eric Dixon Milne Point Unit North Milne #1 & #2 2D Seismic Shallow Hazard Assessment Date: January 16, 1996 An analysis to detect shallow abnormally high geopressure has been conducted in the area surrounding the surface locations of North Milne #1 and #2. Results from the analysis predict that no abnormally high geopressures will be encountered while drilling the North Milne wells. This analysis utilized stacking velocities from two nearby 2D seismic lines to derive interval transit time yrs. depth curves. This method is not as accurate at predicting shallow over pressure zones as a high resolution shallow hazard survey, but it is a good gross indicator of abnormal geopressure conditions. No significant velocity inversions were observed in the data. The I'1-1' curve trends are typical of seismic velocities observed in shallow water and near shore environments throughout the Milne Point unit. Chart 15 displays data from five shot points on line S82HB4; acquired in 1982. Chart 14 shows two shot points from a much older line AIG-25 shot in 1977. Chart 18 displays the two closest shot points to the North Milne surface locations. Based on nearby well control, the following shallow subsurface conditions are predicted: Depth ss -2 to 6 6 to 70 Frozen ground composed of sand silts and gravel Unfrozen sandy silts and clays grading into sand and gravel at about 28 ft.._- 70 to 1650 1650 to 3500 Permafrost UnfroZen sands silts and mud stone of the Gubik and Sagavanirktok. Because no shallow gas or strongly over pressured zones have been encountered in nearby wells we do not feel that a shallow hazard survey is needed.

The Casing Design Summary, Calculations, and a sketch of the proposed casing strings and cement coverage are enclosed. The proposed casing design is in exception to b4) pertaining to wells drilled from a historically shifting natural island. BP makes a formal request that the commission grant the variance to approve the following casing design. BP is confident that shallow gas and abnormal geopressures will not be encountered for drilling this well based on review of seismic data and offset well data as presented in those specific sections of this permit package. Conductor Casing: 20" 91.1# H-40 Welded proposed to be set at +100' md below the mudline similar to the Northwest Milne Point #1 which Conoco drilled from the manmade gravel island. Surface Casing: 9-5/8" 40# L80 Btrc proposed to be set at the Base of the Schrader Bluff Sands into the Seabee Shale at 5102' md (4756' tvd). The Schrader Bluff formation is watered out in the Northern portion of the Milne Point Unit as is evident in the Northwest Milne Point well data and those wells drilling north of Milne Point Unit L and F pads. The 9-5/8" surface casing will provide an adequate shoe to drill through the Kuparuk formation and set 7" into the Miluveach Shale. This standard practice for drilling Kuparuk wells in both the BP operated Milne Point Unit and the Arco operated Kuparuk Unit. Burst Calculations were performed for: 1. Displace Cement with 8.6 ppg EMW on the back side. 2. Bump Plug with 3000 psig with 8.6 ppg EMW on back side. 3. Casing tested to 3000 psig with 8.34 ppg EMW on back side. 4.

Total lost circulation while drilling with 9.6 ppg MW above Cement of backside. A 8.34 ppg emw lost circulation zone at 7000' sstvd allows the fluid level to drop to 1387'. 2. Cementing the casing with 15.8 ppg tail cement channeling to surface and fresh water used to bump the plug. 3. Well Suspended -- Permafrost Freeze Back (see calculation). 4. Total Evacuation was also considered for this string with 9.6 ppg mud on the back side. III. Tensile Calculations were performed for: 1. Running casing with two times the planned dogleg and 9.6 ppg MW. 2. Displacing Cement with 500 psig back pressure. 3. Bumping the Cement Plug with 3000 psig and 9.0 ppg mud. Production Casing: 7" 28# L80 Btrc proposed to be set through the Kuparuk Sands into the Miluveach Shale at 9204' md (8072' tvd). The 7" Iongstring is the standard casing design for Kuparuk wells in both the BP operated Milne Point Unit and the Arco operated Kuparuk Unit. · 2. 3. 4.

In the annulus above the previous casing shoe Pe is defined as follows: a) If inclination exceeds 30 degrees, OR the time since casing installation at potential exposure to the burst loading exceeds 6 months Pe is as for casing expose( via and uncemetned section. b) If inclinat~on less than 30 degrees AND the time since casing installation at potential exposure to the burst loading is less thant 6 months Pe can be taken as mud weight to the top of cement with zero surface pressure. This porvialon which in some circumstances may result in less onerous burst requirements should only be used where there is high confidence in both an adequate cement job, and that mL properties will adequately inhibit settling for this period. 4) No external structural support form the cemnt sheath and formation is to be assumed during design, this requirement reflects uncertainty regarding the presence of voids and micro annuli. 5) The external pressure profile for burst differs from that assumed for collapse. This is because the more onerous requirement in collapse is to assume that mud does not settle out, while in burst it is more onerous to assume it does settle. 6) The time and inclination limits above can be modified if appropriate using specialist advice on mud properties.
