MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission TO: THRU: Julie Heusser, ~ Commissioner Tom MaUnder, /j.-~ ~~ P. I. Supervisor FROM: jeff Jones' SUBJECT: : Petroleum Inspector DATE: 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 failures 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.

Supervisor FROM: LOU Grimaldi, SUBJECT: Petroleum Inspector FILE NO: AJOJARBD.DOC BOP test Nabors rig# 22-E BPX well # X-35 Prudhoe Bay Field PTD #93-199 Friday, February 18, 1994: I traveled to BPX's Drillsite X in the Prudhoe Bay Field to witness the initial BOP test on Nabors rig # 22-E. The rig was just testing the upper pipe rams when I arrived. The choke manifold was tested with all valves passing their pressure test. All other components of the BOPE were tested and all passed with the exception of the Floor valve which leaked on its Iow pressure test, and the Annular preventor which although holding its test pressure developed what appeared to be a hydraulic leak to the bore of the BOP's. This leak was very slight and might have gone unnoticed if not for visual observations of the bore of the BOP. A ieakoff test of the accumulator confirmed that there was a leak in the hydraulic system. I required that before drilling out the surface shoe, these two failures be repaired and retested, this was accomplished by eight P.M. and I approved the rig for further operations. The area surrounding the rig appeared neat and orderly with good access provided. Summary: I witnessed the initial BOP test on Nabors rig # 22-E drilling BPX's well # X-35.

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 witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. · Chairman ~ BY ORDER OF THE COMMISSION dlf/Enclosures CC: Department of Fish & Game, Habitat Section w/o encl.
