Supervisor FROM: jeff Jones, SUBJECT: Petroleum Inspector 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: I 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 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.

The annulus will be freeze protected by dead crude oil. Directionally drill the 6-3/4" pilot hole thru the Sag River and Sadlerochit formation. Run E-line logs: GR/DIL/BHCS. If the logging results are good, plug back the pilot hole, kick off and directionally drill approximately 1000' of horizontal section with MWD/GR tools.
