Well 18-12 was replaced by 18-12A (permit # 97-0123, API# 50-029-21615-01) when the permit was approved 6/27/97. The replacement well incorporates a deepening operation of 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 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. 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.

Pressure test tubing casing annulus. 14. Set BPV. ND BOPE and NU tree. Test tree to 5000 psi . Secure wel 1 and release rig. 15. Run gyro. DS 18-12 DRILLING PROGRAM (Cont'd) 16. Produce well through 4-1/2" slotted liner. Stimulate as required based upon production data. NOTE: a. In accordance with Area Injection Order No. 4, excess non hazardous fluids developed from well operations and as necessary to control fluid level in reserve pit will be disposed of down the 9-5/8" x 13-3/8" annulus. The annulus will be left with a non-freezing fluid during any extended interruption in the disposal process. The annulus will be sealed with 300 sx of cement followed by Arctic Pack upon the completion of the fluid disposal process. b. Existing wells within 200' of the proposed well are DS 18-11, 92' ~ 1260'TVD. c. The drilling fluid program and fluid surface system will conform to the regulations set forth in 20 AAC 25.033. d. Maximum surface pressure is based upon BHP and a full column gas to TD (0.10 psi/ft). e. The AOGCC has waived the requirement for a surface hole diverter system on Drill Site 18.

Dear Mro Oostermeyer: Enclosed is the approved application for permit to drill the above referenced well. The permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Ifhere a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.
