May 7,.2001: I traveled to BPXs Drill Site 12 and witnessed the semi annual safety valve system testing. As the attached AOGCC Safety Valve System Test Report indicates I witnessed the testing of 21 wells and 42 components with 1 failure. The surface safety valve on well 12-12 had a slow leak when pressure tested. This valve was serviced and retested by the operator on this date. Bill Preston (lead DS operator) performed the testing today; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection of the well' houses on this pad was performed during the SVS testing with no problems noted. All well houses inspected were reasonably clean and all equipment aPpeared to be in good condition. Summary: I witnessed the semi annual SVS testing at BPXs Drill Site 12.

Commission Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular Disposal Records from July 25, 1995 through preSent time. We compared your list with our records and are able to provide you with the following data: · Individual Annular DiSposal Logs from the SSD database which coincide with the approved wells on your attached AOGCC Annular Log. The.SSD records are proVided to you in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: · Endicott wells 1-03/P-16, 1,65/N-25, 1-59/0-24 · EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30, L-21, K-38, NMP #1 & #2, K-05, K-02, H-07, K-25, K-37, E-17, F-21,.K-30, K-34, K-21i, F-66, K-06, K-54, K-33, F-49i, K-18 · PBU Wells E-38, 18-34, 15'-42, S,29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal. · The wells listed above in BOLD were not permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a SUndry Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells. Wells drilled between July 25, 1995 and June 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide .you with a cumulative report from our database of records from July 25, 19'95 through the present. From those records, we show the following wells not listed on your report were used for annular disposal: ,. ,Annular Disposal Letter .'. 12/14/98 Endicott wells 1-23/O-15, 1-61/Q-20, 2-40/S-22 · · Exploration well Sourdough #3 - · Milne Point wells F-06, H-05, H-06, · PBU wells-18-30, 18-31, 14~,~-43, E-34, E-36, G-~A, ~d S-33- -05~ '~3-~o 'q~,o~ ~div~d~ logs ~e provided to ~6u fo~ these ~ogs ~s we~l. · Finally, our records show that the B-24 outer annulus was left open (see attached correspondence) Thank you for the opportunity to provide clarity to these records.

As discussed this morning we propose setting three plugs in this well aS detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid 'Wastes. There are no other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter.

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 (B©PE) 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 leum field inspector 659-3607.

NU diverter and function test same. Drill 13-1/2" hole to _ 3477' MD/3388' TVD. Run and cement 10-3/4" 45.5# NT-80 BTC casing to surface. Install blowout prevention equipment consisting of 5,000 psi W.P. pipe rams, blind rams, and annular preventer. Function test BOPE to 5,000/250 psi. Test 10-3/4" casing to 3,000 psi for 30 minutes. A formation leak-off test will be performed 10' below the 10-3/4" shoe. Directionally drill 9-7/8" hole to horizontal in the Sadlerochit @ _ 12,065' MD/8,909' TVD. Run 7-5/8" 29.7# USS- 95 BTC-MOD casing string and cement with Class G cement to 1,000' MD above the casing shoe. Test casing to 3,500 psi. Drill a 6-3/4" hole 10' outside of 7-5/8" casing and test the formation to a minimum of 0.5 ppg over the mud weight to be used to drill the hole section. Displace mud system to FIo-Pro mud system. Directionally drill to horizontal and continue to TD at _+ 13,417' MD/9,023' TVD. Note - Carefully monitor torque and drag to ensure that parameters do not exceed the rating of 3 1/2" DP. Use lubricants as required. Make a hole opener run with a 7-5/8" casing scraper spaced to scrape the packer setting depth. Run 4-1/2" 12.6# L-80 slotted NSCT liner with liner hanger/packer. Liner will be set at TD and lapped _+150' inside 7-5/8" casing shoe. Set liner hanger/packer. Release from hanger/packer. Displace well from FIo-Pro mud to filtered seawater. Spot lithium hypochlorite breaker across slotted liner length Run 4-1/2" L-80 tubing with SSSV, GLM's, and 7-5/8" packer assembly. Set packer and test tubing annulus w/ 3,500 psi. Set BPV. ND BOPE. Freeze protect well to 2100' TVD through shear valve in top GLM station. Release rig. Drilling Hazards · No hydrocarbon-bearing zones expected above the Sag River formation. · Losses have been encountered drilling the Kingak, Sag River, and Sadlerochit formations on DS 12. · A minimum of 9.8 ppg mud weight will be used to drill the Cretaceous injection interval. This will allow a 100 psi tripl/ margin over the expected 9.5ppg EMW @ 4600' TVDSS. Disposal Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well DS 12-36 for annular pumping. Request to AOGCC for Annular Pumping Approval for DS 12-36: 1. Approval is requested for Annular Pumping into the DS 12-36 10-3/4" x 7-5/8" casing annulus. 2. As referenced in Area Injection Order #4, there are no drinking water aquifers in the Prudhoe Bay Field Eastern Operating Area (including the Lisburne Oil Pool), as the average level of Total Dissolved Solids (TDS) at the ambient water within the proposed project area is above 10,000 ppm. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 10-3/4" casing shoe will be set at 3477' MD (3388' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. 4. The burst rating (80%) for the 10-3/4" 45.5# NT-80 casing is 4170 psig while the collapse rating (80%) of the 7-5/8" 29.7# USS-95 casing is 5760 psig. The break down pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 2740 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7-5/8" casing is filled with gas). MASP = 4170 psig - ((fluid density ppg - 1.9) X 0.052 X 10-3/4" Casing Shoe TVD) 5. 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. 6. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.
