Memorandum State of Alaska Oil and Gas Conservation Commission To: Well File: Prudhoe Bay Unit Permit # 195-185 July 9, 2002 Re: Administrative Abandonment Action Prudhoe Bay Unit 15-42, Permit # 195-185 This memo will remain at the front of the subject well file. Well PBU 15-42 was replaced by PBU t5-42A (permit # 200-069, API# 50-029-22624-01) when the permit was approved 05/24/2000. 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 databases 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.

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 B©PE 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.

Fluid Handling: All drilling and completion fluids can be annular injected. Well DS 15-47 has been permitted for annular injection. Request to AOGCC for Annular Pumping Approval For DS 15-42 , , . , , , Approval is requested for Annular Pumping into the DS 15-42 9 5/8" by 7" casing annulus. As referenced in Area Injection Order #4 there are no drinking water aquifers in the Prudhoe Bay Field Eastern Operating Area ( including the Lisburne Oil Pool), as the average level of total dissolved solids (TDS) at the ambient water within the proposed project area is above 10,000 ppm. There are no domestic or industral use water wells located within one mile of the project area. The 9 5/8" casing shoe will be set at 3783'MD (3530'TVD) which is below the permafrost and in the shale formations in the Sagavanirtok above the Ugnu Formation. The burst rating (80%) for the 9 5/8" 47#/ft N-80 casing is 5496 psig while the collapse rating (80%) of the 7" 26#/ft NT-80 is 4328 psig. The breakdown pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated accourding to the following equation and is 1400 psi for a 17.0 ppg fluid in this well (assumes worst case in which 7 inch casing is filled with gas). MASP=4170 psig - ((fluid density ppg - 1.9) * 0.052*3530 TVD) A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 10/30/95 which demonstrates the confining layers, porosity and permeeability of the injection zone. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur. AREA WELL Prev.

Memorandum State of Alaska Oil and Gas Conservation Commission To: Well File: Prudhoe Bay Unit Permit # 195-185 July 9, 2002 Re: Administrative Abandonment Action Prudhoe Bay Unit 15-42, Permit # 195-185 This memo will remain at the front of the subject well file. Well PBU 15-42 was replaced by PBU 15-42A (permit # 200-069, API# 50-029-22624-01) when the permit was approved 05/24/2000. 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 databases 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.

P O Box 196612 Anchorage, AK 99519-6612 Dear Mr. Frazier, Re~ Administrative Abandonment Action Prudhoe Bay Unit 15-42, Permit # 195-185 Well PBU 15-42 was replaced by PBU 15-42A (permit # 200-069, API# 50-029-22624-01) when the permit was approved 05/24/2000. 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 databases require each conductor has only one permit number and APl 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: Terri Hubble
