G To: AOGCC Date: August 28, 2007 From: Jim Nigh - BPXA GPB Rotary Drilling Subject: 14-18A Application for Sundry Approval- P&A for Sidetrack Operations The purpose of this sidetrack is to create offtake in the Sag River Formation. This new sidetrack will replace 14-18A, which has been a long term shut-in well since 2000 The Ivishak reservoir (e.g. Z4) will be completed if it turns out to be economically attractive. Should the Ivishak reservoir be completed, the Sag target will be preserved as a future CTD candidate. N2ES will pull the existing tubing string before the well is sidetracked at -4,300' to the 8.5" TD at -11,056' to top set the Sag River. A 7" liner will be run, fully cemented. A 6-1/8" pilot hole will be drilled out of the 7" shoe down to the Ivishak. Depending on the logging results, the Asset Team may case and produce this pilot hole (via cemented and perforated solid liner) or plug it back with cement and drill horizontally into the Sag for -2,500' to a TD of 13,552' MD. This horizontal production hole will be completed with a 4-1/2" slotted liner. A 4-1/2" chrome tubing string will be run for production. ~;__t-~_ Jim Nigh GPB Rotary Drilling Engineer Ph: 564-5220 I ~- ,~It O"ty \,VtlL f !art waJ J,7; I OF froJIICf/O~ to aba,JrJl It Jp di",'//"r/ q5 t?/í'ý/"~/~ 1/¡;,/1I?t'~ ~"17 /i /levU "b ~ 0 .

BY v~t.~ Robert N. Chdstenson Cd 10-403 Rev 06/15/88 SUBN T IN TRIPUCATE DS 14-18A CT Drilling Completion Intended Procedure Background: Well 14-18A was sidetracked from 4/12/98 to 4/30/98. The Shublik Interval was drilled as planned and a liner cemented in place. After drilling out 272 feet into the Sag River Formation, CTD operations were suspended due to MWD problems. Target TD was not achieved. Arco attempted to produce this well but it was uneconomic. Plans are to return to the well to complete ddlling operations. Permit to Drill #98-07 was approved on 1/22/98. The operations below are consistant with the odginal ddlling permit. Ddlling operations are planned to resume around March 1, 1999. Intended Procedures: Directionally drill 2-3/4" x -2000' horizontal well to access Sag reserves. Drilling will start at approximately 10260' in the existing open hole. Crude will be used as the drilling fluid to help overcome fluid loss problems encountered during the previous drilling of the Sag interval in this well. A new MWD system will be run due to problems encountered in getting a signal in the MWD tools originally used. Run 2-3/8" slotted liner to TD. Return well to production.

Continuous inclination was provided, which proved to be a major advantage in determining if we were building or dropping angel before we got to a survey point. Survey on the fly was used through out the well, thereby reducing the risk of getting stuck. FORMATION EVALUATION Realtime GR values were provided in order to identify formation lithology. In doing so we were possible to geosteer the sands and shales. ~,-~nqliil,~oj~ ~ Anadrill LESSONS LEARNED Survey quality based on direction we were drilling, again was a problem on this well as in the past. We will be using a survey program called MAGCOR,(which after 4 surveys have been taken at the same depth, in 4 different tool faces, 0, 90, 180, 270.) Which will determine what axis is most effected, and apply a correction to compensate for that interference. Anadrill appreciated the opportunity to provide ARCO Alaska Inc. with MWD SHARP and (GR) services on 14-18a.

The permit to rcdrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and docs 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) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given inspector on thc North Slope pager at 659-3607. --.~-.-____~ _ BY ORDER OF THE COMMISSION dlffEnclosurcs CC; Department of Fish & Game. Habitat Section w/o cncl.
