Supervisor Chuck Schev~, Petroleum Inspector DATE: August 10, 2000 SUBJECT: Location Clearance West Gwydyr #1 PTD #199-121 Thursday, August 10, 2000; I made a Location Clearance Inspection on the abandoned exploratory well West Gwydyr~l. I was accompanied today by Scott Grieve (BPX) and Ned Arey (North Slope Borough). We flew to the location via Air Logistics helicopter West Gwydy~l was drilled and abandoned this last winter exploratory season. We circled the location several times at a Iow altitude before landing. Other than the mound of clean gravel over the cellar there were no indications of any drilling activity at this location. A walk around the area revealed a small oily spot (approximately l-foot square) on the tundra. This oily spot was roughly 100 yards from the well cellar in the direction of the ice road. Mr. Grieve indicated BPX would get this spot cleaned up. We flew the ice road path this was clean and seemed well vegetated. I recommend this location be approved for final clearance.

REMARKS: Poor oil show in very fine well sorted glauconitic Sag River Sandstone from 10646' to 10626': varying spotty to locally abundant moderately bright yellowish white to greenish yellowish white sample fluorescence; visible pale to very light brown oil staining; no visible cut in plain light; instant bright bluish white to yellowish bluish white cut fluorescence, which generally masks spotty slowly expanding streaming; pale golden brown residual cut in plain light that fluoresced bdght yellow;, upper zone of sand had estimated visual porosities ranging from very poor to good based on amount of calcite cementation. Note show rating downgraded due to lower than anticipated LWD resistivities and visible "tightness" caused by calcite cement. Poor to marginally fair oil show in fine upper to medium upper moderately well sorted Ivishak Sandstone from 10817' to 10870': 30-40% bdght yellow sample fluorescence and 20-40% very dull whitish yellow sample fluorescence; visible irregularly patchy or spotty very light to light brown oil staining; no visible cut in plain light; dominant slow dull to marginally bdght whitish yellow to bluish white cut fluorescence with slow very wide non-milky diffuse streaming; spot cut fluorescence from some individual pieces was fast bdght bluish yellowish white with faster streaming; no visible residual dry cut dng (with rare light brown exceptions) that ranged from dull yellowish gold to bdght yellow. Estimated visual porosities are good or very good. Show ratings downgraded due to Iow LVVD resistivities and apparent wetness.

I witnessed the HOWCO EZSV cement retainer set 90' from the surface casing shoe. I witnessed cementing thru the retainer, a volume of cement that would extend from the cmt. retainer to 109' below the surface casing shoe. A calculated volume of cement was placed on top of retainer to 52' above retainer. The surface casing & cement retainer were then tested to 3000 psi. for 30 minutes. SUMMARY: I witnessed the RIH & setting of the cement retainer effectively segregating uncased & cased portions of the wellbore on West Gwyder #1. I witnessed the volumes of cement pumped & the placement of cement for this segregation plug. Tested segregation plug to 3000 psi. for 30 minutes. Attachments- none cc; CONFIDENTIAL Csg.

The casing was tested to 3000 psi and after a small initial decline held steady for thirty minutes. The Wiper plug and float collar were drilled as was the cement to the shoe and twenty feet of new hole. I observed returns and saw a indication of clay and shale coming across the shakers. The hole was circulated clean with a 10.0 mud weight constant going in and coming out of the hole. The leak off test was started and the drillpipe pressure raised slowly to 1200 psi @ 6 strokes per minute (approx. 15 p.p.g. EMW) where I noticed a decline of the rate of pressure increase per stroke. The pumps were run a total of a 40 strokes to a pressure of 1260 psi. The last six strokes were obviously pumping away to the fractured formation. The pumps were shut down with twenty psi lost in the first ten seconds. The pressure was watched for ten minutes with less then a ten- psi decline stabilized at the end. A calculated E.M.W. of 16.5 p.p.g, was arrived at.

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. 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. Robert N. Christenson, P.E.

Seccombe BP Exploration Alaska Subject: West Gwydyr 01 January 04, 2000 Steve, RECEIVED JAH 07 2.000 Alaska Oil a Gas Cons. Commissior Anchorage As per our phone conversation on January 04, 2000, this letter is to document the status of our shallow drilling hazard analysis for the proposed West Gwydyr 01 well scheduled to spud this month. We would like to reiterate that it is always BP Exploration Alaska's intent to conduct our operations in a safe and environmentally responsible manner. What follows are the major points covered in our conversation: Proximal offset well data shows no indication of over-pressured strata or shallow permafrost hydrate issues. The primary offset wells utilized were the Gwydyr Bay State Unit No. 01 and the Plaghm Beechy Point No. 01 as they are within the same major fault block as and straddle the proposed Wgwydyr-O1 location. Mud and Wireline logging information was utilized in this analysis. Stacking velocities from the 1995 Fullsail 3D data processing sequence show no indication of either velocity regression due to over-pressured strata or shallow hydrate (trapped gas). This velocity data is analyzed primarily for imaging and is probably unreliable for shallow, permafrost analysis. The analysis of both offset well and 3D seismic data show no indication of hazards, but 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. We will ensure that all personnel associated with the West Gwydyr 01 operations, both in Anchorage and at the rig site, will be aware of the possibility of encountering drilling hazards as per the above. Please contact either Jim Seccombe (907-564-4814) or Dean Chergotis (907-564-5131) if there are any further issues. Thank You, ~ja~ C~ S~cc mbe /'.

I have made the changes you requested regarding the potential for encountering shallow gas and gas hydrates in the surface hole, shallow gas in the intermediate hole, and the possibility of swabbing in gas while tripping.

Well Control: Well control equipment consisting of 5000 psi working pressure pipe rams(2), blind/shear rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures. Based upon calculations below BOP equipment will be tested to 5000 psi Diverter, BOPE and drilling fluid system schematics for Nabors 7ES are on file with the AOGCC. Production Interval- , Maximum anticipated BHP: · Maximum surface pressure: 5362 psi @ 10,970' TVDss - Ivishak @ TD (9.4 ppg) 4265 psi @ surface (based on BHP and a full column of gas from TD @ 0.10 psi/ft) · Planned BOP test pressure: 5000 psi Planned completion fluid: 8.4 ppg KCI Brine / 6.8 ppg Diesel Drilling Hazards/Contingencies: HYDROGEN SULFIDE - H2S · West Gwydyr Bay ice pad location is not designated as an H2S drill site, however Standard Operating Procedures for H2S precautions should be followed at all times. DRILLING CLOSE APPROACH: There are no Close approach issues. All existing wells in area are greater then 1300ft away and their current status is P&A. SURFACE HOLE SECTION: · The surface hole interval on V-200 was relatively problem free. · S-Pad surface holes: Minor tight hole has been encountered in the clay sections below the permafrost in the SV sands. · There is a potential of encountering shallow gas and a potential for encountering gas hydrates in the surface hole. In the event these are encountered, standard BP / Shared Services Drilling policies and well control practices will be followed. The drilling crew is MMS certified and proper tripping and well control procedures will be followed. · Beech State #1 to the south, experienced hydrate gas in the SV1 & SV2 sands. K pad in Milne Point to the west also has a history of hydrates below the permafrost. · Differential sticking could be problematic in this hole section adjacent to the permeable SV Sands. Avoid leaving drill string stationary for extended periods, tighten fluid loss properties of mud, and string in Barofibre prior to penetrating sand intervals. INTERMEDIATE HOLE SECTION: · No Major hole problems are anticipated. · The LOT test is planned after drilling 20' MD of formation. A LOT of 12.5 ppg EMW, which is -2.0 ppg over planned mud weight, would provide a kick tolerance for the 10-3A'' shoe of -392psi, 76 bbls, 2665' MD maximum height at the bit, assuming an influx of gas at TD of section, 10875' MD. · Ugnu and Schrader may be hydrocarbon-bearing. · There is a potential of drilling into shallow gas zones in the intermediate hole section. If gas is encountered, standard BP / Shared Services Drilling practices and well control policies will be followed. The drilling crew is MMS certified and proper tripping and well control procedures will be followed. · Kingak shale and lost circulation practices will be used while drilling this hole section. · The well path will cross one fault with - 200' of throw in the Kingak formation. This fault is not expected to have lost circulation, however, it will be discussed within the well plan and measures will be taken to control lost circulation or other problems associated with drilling across the fault. PRODUCTION SECTION: No major hole problems are anticipated in this section. No faults are predicted. Lost circulation plan will be in place if losses are encountered. A FIT test to 12.5 ppg is planned after drilling 20' MD of formation using existing 10.5 ppg mud system. A FIT of 12.5 ppg EMW, which is -2.5 ppg over planned mud weight, would provide an infinite kick tolerance for the 7 5/8" shoe, 4839' MD maximum height at the bit, (-3787' MD above shoe), assuming an influx of gas at TD of section, 11927' MD. Disposal: · No annular injection in this well. · Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. · Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I wastes to Pad 3 for disposal. DRILL AND COMPLETE PROCEDURE SUMMARY Pre-Rig Work: The 20" conductor will be set during ice pad construction. 1.

Well Control: Well control equipment consisting of 5000 psi working pressure pipe rams(2), blind/shear rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures. Based upon calculations below BOP equipment will be tested to 5000 psi Diverter, BOPE and drilling fluid system schematics for Nabors 7ES are on file with the AOGCC. Production Interval- . Maximum anticipated BHP: · Maximum surface pressure: 5362 psi @ 10,970' TVDss - Ivishak @ TD (9.4 ppg) 4265 psi @ surface (based on BHP and a full column of gas from TD @ 0.10 psi/ft) · Planned BOP test pressure: 5000 psi Planned completion fluid: 8.4 ppg KCI Brine / 6.8 ppg Diesel Drilling Hazards/Contingencies: HYDROGEN SULFIDE - H2S · West Gwydyr Bay ice pad location is not designated as an H2S drill site, however Standard Operating Procedures for H2S precautions should be followed at all times. DRILLING CLOSE APPROACH: There are no Close approach issues. All existing wells in area are greater then 1300ft away and their current status is P&A. SURFACE HOLE SECTION: · The surface hole interval on V-200 was relatively problem free. · S-Pad surface holes: Minor tight hole has been encountered in the clay sections below the permafrost in the SV sands. · There is a potential of encountering shallow gas and a potential for encountering gas hydrates in the surface hole. In the event these are encountered, standard BP / Shared Services Drilling policies and well control practices will be followed. The drilling crew is MMS certified and proper tripping and well control procedures will be followed. · Beech State #1 to the south, experienced hydrate gas in the SV1 & SV2 sands. K pad in Milne Point to the west also has a history of hydrates below the permafrost. · Differential sticking could be problematic in this hole section adjacent to the permeable SV Sands. Avoid leaving drill string stationary for extended periods, tighten fluid loss properties of mud, and string in Barofibre prior to penetrating sand intervals. INTERMEDIATE HOLE SECTION: · No Major hole problems are anticipated. · The LOT test is planned after drilling 20' MD of formation. A LOT of 12.5 ppg EMW, which is -2.0 ppg over planned mud weight, would provide a kick tolerance for the 10-3,~'' shoe of -392psi, 76 bbis, 2665' MD maximum height at the bit, assuming an influx of gas at TD of section, 10875' MD. · Ugnu and Schrader may be hydrocarbon-bearing. · There is a potential of drilling into shallow gas zones in the intermediate hole section. If gas is encountered, standard BP / Shared Services Drilling practices and well control policies will be followed. The drilling crew is MMS certified and proper tripping and well control procedures will be followed. · Kingak shale and lost circulation practices will be used while drilling this hole section. · The well path will cross one fault with - 200' of throw in the Kingak formation. This fault is not expected to have lost circulation, however, it will be discussed within the well plan and measures will be taken to control lost circulation or other problems associated with drilling across the fault. PRODUCTION SECTION: No major hole problems are anticipated in this section. No faults are predicted. Lost circulation plan will be in place if losses are encountered. A FIT test to 12.5 ppg is planned after drilling 20' MD of formation using existing 10.5 ppg mud system. A FIT of 12.5 ppg EMW, which is -2.5 ppg over planned mud weight, would provide an infinite kick tolerance for the 7 5/8" shoe, 4839' MD maximum height at the bit, (-3787' MD above shoe), assuming an influx of gas at TD of section, 11927' MD. Disposal: · No annular injection in this well. · Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. · Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I wastes to Pad 3 for disposal. DRILL AND COMPLETE PROCEDURE SUMMARY Pre-Rig Work: The 20" conductor will be set during ice pad construction. 1.
