Supervisor DATE: Jeff JOnes, Petroleum Inspector SUBJECT: December 9, 2000 Safety Valve Tests Prudhoe Bay Field BPX ! X-Pad SaturdaY, December 9, 2000: I traveled to BPX's X Pad in the Prudhoe Bay Field to Witness Safety Valve System tests. Merv Liddelow, BPX representative in charge of the testing, performed the tests in a safe and proficient manner. Of the 26 wells tested, 3 fai!ures were witnessed. Well X-14A's SSV failed to close and well X-19B's pilot was frozen and the SSV failed to close. Mr. Liddelow indicated to me on 12/10/00 that these items have been corrected and successfully re-tested. The AOGCC test reports are attached for reference. I conducted 26 well hOuse inspections concurrent with the SVS tests. A slight crude oil leak was noted on a wellhead flange of well X-19B. Mr. Liddelow indicated he would have this item addressed. No other exceptions were noted. SUMMARY: ! WitneSsed SVS tests and conducted well house inspections on BPX'S X Pad. 26 wells, 53 components tested, 3 failures. 26 well houses inspected.

The permit to redrill 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) must be given to allow a represcntative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Commissioner BY ORDER OF THE COMMISSION dlf/Enclosures CC~ Department of Fish & Game.

The sidetrack, X-21a, will target bypassed "attic oil" reserves in upper Zone 4B. This sidetrack will be conducted in two phases. Phase 1: Set Whipstock: Planned for Nov. 8, 1999. · ^ Tubing Integrity Test will be performed. · The whipstock drift and Kinley caliper will be run. · ^ mechanical whipstock will be set on e-line at approx. 9000' MD. Phase 2: Cement perfs, mill window and drill sidetrack: Planned for Nov. 11, 1999. Directional drilling coiled tubing equipment will be rigged up and utilized to cement perforations, mill the window, and drill the sidetrack to a planned TD of 11,027' MD (8,748' TVDss). Mud Program: · Phase 2: Seawater and FIo-Pro (8.6 - 8.7 ppg) Disposal: ~ - No annular injection on this well. - All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. - All Class I wastes will go to Pad 3 for disposal. Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 8,740' MD and cemented with approx. 25 bbls. cement to bring cement 200 ft above the window. The well will then be perforated with coiled tubing conveyed guns. Well Control: - BOP diagram is attached. , - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. - Kick Off: 9,010' MD (8,673' TVD ss) - TD: 11,027' MD (8,748' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · A Gamma Ray log will be run over all of the open hole section. · A Memory Induction log will be run at TD.
