SMITH SUBMIT IN TRIPLICATE DES{... .~PTION SUMMARY OF PRO, ,~SAL ARCO Alaska, Inc. proposes to to perforate DS 4-27 at selected intervals within the Sadlerochit formation. All wireline work will be done through a 5000 psi WP BOP/Lubricator, tested to 1.2 times the maximum expected surface pressure. The SSSV will be installed at the conclusion of the perforating and clean-up operation. The well is currently on source water injection. Source water will be in the wellbore during perforating operations. The reservoir pressure at the perforation depths is approximately 3775 psi.

Waivers to Rules 6 and 11 of Conservation Order 165. Mr. D. F. S cheve ARCO Alaska, Inc. P. O. Box 100360 Anchorage, AK 99510-0360 Dear Mr. Scheve '. By letter dated October 21, 1986, waivers to Rules 6 and 11 of Conservation Order 165, as amended by Conservation Order No. 213, were requested for DS 4-18, 4-21, 4-24 and 4-27. These wells are currently on a rotating production schedule. They are produced for 7 or 8 days, and are shut in for 20 or 21 days. A static pressure survey is proposed to be taken at the end of a shut in period in these wells to satisfy the pressure survey requirement in Rule 6b of CO 165. Static surveys in these instances will yield an accurate measurement of reservoir pressure. Therefore, substitution of a static survey for the transient survey required in Rule 6b of CO 165 is hereby approved for Prudhoe Bay Unit wells DS 4-18, 4-21, 4-24 and 4-27. These wells are producing from 55 feet or less of perforations. Ail perforations are in zone la. Since all flow would necessarily enter from this zone, a productivity profile as required by Rule lla of CO 165 is not needed. Therefore, the Commission approves your request to waive the production profile required by Rule lla of CO 165 on Prudhoe Bay Unit wells DS 4-18, 4-21, 4-24 and 4-27.

Well 4-27 is presently on a rotating production schedule of producing for 7 days followed by a shut in period of 21 days. The static bottomhole pressure is planned to be taken at the end of the shut in period. The static bottomhole pressure survey should provide an accurate measurement of reservoir pressure. · Permission to waive the production profile prescribed in Conservation Order 165, Rule 11a. Only 55' of perforations were shot in 4-27. All of the perforations were shot in Zone la thereby negating the need for a spinner survey. Additional perforations in Zone I are planned. The timing of the perforations, however, is after the initial six month time period has passed. A production profile will be run subsequent to the additional Zone I perforations. ~'- STATE,OF ALASKA '-- ~ ALASKA-OIL AND GAS CONSERVATION L,,...,,M MISSION ~ WELL-COMPLETION OR RECOMPLETION REPORT AND LOG ,, 1.

A 20", 2000 psi annular diverter might not be used for this well. A waiver of the surface hole diverter system for Drill Site 4 has been requested from the AOGCC. The 13-5/8", 5000 psi, RSRRA BOPE stack will be installed and tested (rams 5000 psi, annular 3000 psi) weekly upon installation and operationally tested each trip. After reaching TD, logs will be run across selected intervals. The well will be completed as an injector using a workover rig at a later date. A 4-1/2" tubing string and packer will be run and set above the Sadlerochit. A downhole safety valve will be installed and tested upon completion of the job. Selected intervals will be perforated in the Sadlerochit formation and reported on subsequent reports. Reserve pit fluids will be disposed of down the 7-5/8" x 10-3/4" annulus of this well.
