May 27, 1998 Allen Sherritt Doyon 9 Operations Drilling Engineer L2-18 Sundry P&A Operations Summary: Doyon 9 will be moving to Well L2-18 upon completion of Well L2-11 which is estimated to be completed on the 11'h of June. The following is an outline of the proposed Pre-Rig work needed to be done prior to Doyon 9 moving over the well. Also, included is an outline of the proposed rig operations for L2-18A. If you should have any questions please contact Allen Sherritt @ 564-5204 / 275-8726 / 243-6842. Pre-Rig Operations: The objective of the pre-rig work is to ascertain the condition of the 9 5/8" casing presently in the hole; Pump cement to P&A the existing completion and perforations; Chemical cut existing tubing in the first full joint above production packer; and test the 9 5/8" pack offs. 1. Notify AOGCC of initiation prior to commencing any P&A operations. 2. NUonWell. 3. Perform CMIT on 9 5/8" casing and 2 7/8" tbg to 3000 psi. IA/OA. 4. Bullhead Seawater down tubing to kill well and establish injectivity. Note: If the tubing fails pressure test or there is Iow injectivity, the well will have to be P&A'd with Coiled Tubing. , , , 8, 9. 10. Pump 142sks. (24 bbls. Plus 5 bbls for down squeeze into perf's) of class G, 15.8 ppg cement to place TOC @ 12,465' MD. (100' MD above top perforation.) RIH with chemical cutter and chemically cut tubing @ ~11,427'MD (First full joint above 9 5/8" Packer.) Notify Ops. Drilling Eng. If unable to cut tubing @ desired depth. Freeze protect tubing. Test packoffs on tubing and 9 5/8" annulus, and carefully cycle Iockdown screws. Set BPV. Clear location, dig out cellar, remove electrical lines, flow lines, and remove well house. RDMO Operations The rig will MIRU. Pull BPV. Circulate out freeze protection and circulate well with seawater. Set BPV. ND tree. NU BOP. Test BOP. Pull the tubing to the chemical cut above the production packer. Change packoff if failed in Pre-rig. RIH and set 9 5/8" EZSV ~ 10,020'MD on wireline as per CCL. Pressure test casing to 3000 psi for 30 mins. RIH and set 9 5/8" whipstock/milling assembly and set 25° right of highside. Displace to 4% KCI Quikdriln mud. Mill window to place KOP @ 10,000' MD.

Therefore, we have decided to shutdown the waterflood pilot. Shutdown will include the conversion of the five existing waterflood injection wells to producers within the next 6 weeks. Actual conversion timing will depend on both LPC water handling capacity and gas lift installation timing. ARCO ALASKA INC.

Dear Mr. Oos'termeyer: 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. Where 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.
