ON OR BEFORE Memorandum State of Alaska Oil and Gas Conservation Commission To: Well File: Prudhoe Bay Unit 15-33 Permit # 94-0024 August 30, 1999 Re: Administrative Abandonment Action Prudhoe Bay Unit 15-33 Permit # 94-0024 This memo will remain at the front of the subject well file. Well 15-33 was replaced by 15-33A (permit # 99-0060, API# 50-029-22448-01) when the permit was approved 7/01/99. 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(e) 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. .

Due to the numerous station points on these wells we were unable to process the full survey and found it necessary to split each well into three separate surveys. Each page is labeled at the bottom. The second survey ties into the first and the third survey ties into the second to simulate a complete survey.

International Airp°~t Road Anchorage, AK 99518 Attn: Scott Levad I would like to clarify Arco Alaska's requirements for delivery of directional survey data in light of recent confusion, particularly on wells with unplanned sidetracks. We would like each vender to provide survey data for each track in which data is collected for each job. The data should be provided digitally via electronic transmission or 3.5" floppy and a paper copy of the calculated values. A seperate digital f'fie of the calculated values is desirable but not required. The data should be presented from surface to td on new wells or ko to td for each sidetrack. The date surveyed should be the last day data was collected for each track. If multiple tracks are surveyed for a job, the data does not need to be on seperate disks, but each file should be clearly labeled to distinguish which file belongs to which track. Venders are not responsible for presenting merged surveys, particularly if the uphole survey is from another vender. If a merged survey is presented, the source and depth range of the merged survey should be clearly labeled. Each vender should provide an accurate tie-in point if applicable. Please call if you have any questions. Thanks for your cooperation. D~rdre (Dede) Schwartz Associate Explorationist Exploration Computer Services (907) 263-4483 ARCO Ala,l(,i.

The lithological evaluation was performed for the Horizomal ! Slimhole section. The Engineer and Sample Catcher on location performed their duties on a twelve hour tour basis. Lag calculations were gas pill verified on a 12 hour minimum basis. Sample evaluations were performed by Tom Mansfield, Sperry-Sun Drilling Services' Geologist/Logging Engineer, inhouse at our Anchorage lab. Tom was able to give an interpretive analysis of lithology by utilizing FE/MWD data recorded from the wellsite. $ UB-$ URFA CE DIRECTIONAL m--~ UIDANCE SURVEY m~-~ ONTINUOUS [-~ OO L ivt~-,,, /_ 5 'i'394.

Johnstor~pproved L;opy Returned Commissioner Date - SUBMIT IN TRIPLICATE PROPOSED DRILLING AND COMPLETION PROGRAM DS15-33 Procedure-REVISiON #1 SITUATION: Because of a more detailed geological interpretation of this well's BHL since the Drilling Permit was submitted and approved, the BHL has been shifted 200' to the NW relative to the original start of slotted liner as specified in the Drilling Permit that was recently approved. The purpose of shifting this BHL is to allow for a pilot hole to be drilled within 400' of the new proposed start of the slotted liner due to a minor fault exists just south of the beginning of the slotted liner interval. This pilot hole is necessary such that the sand/shale sequence within Zone 1 can be determined (difficult to assess due to the fault) so the correct target sand can be found and produced from the horizontal slotted liner section. Below are the well's original BHL information, the new location, and the location of the pilot hole that will be plugged back after it is drilled. In addition, below is also the revised summary of operations.

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. ~ ChairmanX~~_.~ BY ORDER OF THE COMMISSION dlf/Enclosures CC: Department of Fish & Game, Habitat Section w/o encl.
