P O Box 196612 Anchorage, AK 99519-6612 Dear Mr. Gunkle, Re: Administrative Abandonment Action Pmdhoe Bay Unit P-12A Permit # 195-022 Well P-12A was replaced by P-12B (permit # 200-133, API# 50-029-22136-02) when the permit was approved 8/29/2000. The replacement well incorporates an extension to a new bottom hole location using the existing well bore. The 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 are 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 AP1 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. Please notify other cognizant personnel in your organization so that the well will be correctly identified on subsequent reports and applications submitted to the Commission. Sincerely, Steve McMains Statistical Technician AOGCC cc: Gary Benson Terri Hubble Memorandum State of Alaska Oil and Gas Conservation Commission To: Well File: Prudhoe Bay Unit P-12A Permit # 195-022 November 20, 2000 Re~ Administrative Abandonment Action Prudhoe Bay Unit P-12A Permit # 195-022 This memo will remain at the front of the subject well file. Well P-12A was replaced by P-12B (permit # 200-133, APl # 50-029-22136-02) when the permit was approved 8/29/2000. 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, AP1 number and well data.

The permit to re-drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting re-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 representative of the Commission to witness a test of BOPE installed prior to drilling a new hole. Notice may be given by contacting the Commission's petroleum field inspector on the Nodh Slope pager at 659-3607. David W.
