Administrative Abandonment Action Prudhoe Bay Unit C-37 Permit # 193-055 This memo will remain at the front of the subject well file. Well C-37 was replaced by C-37A (permit # 201-143, API# 50-029-22360-01) when the permit was approved 8/10/2001. The replacement well incorporates an extension to a new bottom hole location using the existing well bore. This extension, along with the original hole, will be used for production of hydrocarbons. A review of both well files indicates administrative abandonment of the originating well bore is appropriate according to current AOGCC procedures for wells where additional permitted extension is drilled from an existing well bore. 20 AAC 25.005(a) requires a Permit to Drill for each hole drilled below the conductor unless drilled to straighten the original hole, sidetrack junk, or correct mechanical difficulties. In addition, AOGCC data bases require each conductor has only one permit number and API number. Administrative abandonment of the original permit only eliminates duplication in the databases. Information for the original well and its replacement will be maintained in their respective files. The operator has been notified of this action. All future correspondence with the AOGCC should reflect the new permit number, API number and well data.

PO Box 196612 Anchorage AK 99519-6612 Re: PBU C-37 BP Exploration (Alaska) Inc. Permit No: 193-055 Dear Ms. Stewman: BP recently submitted a sundry application for the subject well seeking approval to P&A portions of the existing wellbore in preparation for sidetrack. After reviewing the proposed operational plan and information, it has been determined that a sundry application is not needed in this case. The intended plan is to develop new wellbore by drilling out of the liner shoe and the existing production intervals will be abandoned when the new liner is cemented in place. Approval of the PTD application for C-37A will provide the necessary approval for the abandonment of the existing production intervals. After receiving the completion report for the "sidetrack", we will administratively abandon the present production intervals. Daniel T. Seamount, Jr. Commissioner STATE OF ALASKA ....

The following summarizes the procedure required to prep C- 37 for drilling and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. t. Tree wing & master valves will be tested. 2. Using slickline, tubing will be drifted, a caliper run on the liner & gas lift mandrels will be dummied off. 3. Inner Annulus will be liquid packed and pressure tested. Slickline prep work is expected to commence August 1st. Coil tubing drilling operations, as detailed below will commence August 15th, 2001. 1. A 3" horizontal extension, -1600' long will be drilled out of 4-1/2" slotted liner into Zone 1. 2. The sidetrack will be completed with a 2-3/8", solid, cemented & perforated liner. 3. The cementing in place of the 2-3/8" liner will serve to abandon the existing completion, which consists of perforations and a 4-1/2" slotted liner.

I. Supervisor O~lo%-O I~ FROM: Jeff Jones, SUBJECT' Petroleum Inspector Safety Valve Tests PBF/PBU C Pad MarCh 23, 2.001: I traveled to Prudhoe Bay Field to witness Safety Valve System tests on BPX's C Pad. Well house inspections were also conducted. Merv Liddelow was the BPX representative in charge of testing, and performed the tests in a professional manner. Twenty-one wells on C-Pad were tested with five failures witnessed. The SSV on well C-04A tripped below 50% of the separator psi, the SSV on well C-07A failed to hold D/P, the pilot on well C-19B was frozen, the pilot on well C-20B failed to trip and the SSV failed to hold D/P. Mr. Liddelow indicated to me that all failures were repaired within 24 hours. I inspected 21 well houses and noted leaking wing valves on wells C-03A, C-13A and C-19B. A hydraulic fluid leak on the SSV control line of well C-05 and a slight crude oil leak from the SSV on well C-25A were also noted. Mr. Liddelow indicated he would have these items corrected. The AOGCC test forms are attached for reference. SUMMARY: i witnessed the SVS tests on twenty-one oil producing wells on C Pad in the Prudhoe Bay Field. 21 wells tested 42 components, 5 failures witnessed, and 11.9% failure rate. 21 well houses inspected.

As the attached BOP test report shows, there were 4 flange leaks and the hydraulic seal rings leaked. This stack was disassembled and new seals, o - rings and slide plates were installed. Apparently when the top on the annular was screwed back on the new seals were damaged. The seals were replaced and all of the flanges were retighened. All the components tested properly.

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. David W.
