The objective of the re-drill is to access Zone 1 reserves. Please confirm with the Rig Supervisor for the exact rig move schedule. Wireline and PE work to prepare the 7-28 well before the rig move should be charged to AFE 4J0360. Objective: The objective of pre-rig work activity displace the hole to seawater, pump a cement P&A plug, and cut the 4- 1/2" tubing above the production packer in preparation for tubing removal. The well will be freeze protected following P&A activities. Pre-Rig Operations: Note: original elevation 65' AMSL, OKB to BF = 35' 1. Notify an AOGCC representative prior to beginning P&A operations. 2. Check and service the wellhead, pressure test the 9-5/8" packoffs to 3500 psi Notify Jim Smith at 564- 5026 of results. 3. Kill the well with Seawater. 4. Perform cement P&A of the bottom hole, pumping 20 bbls (100 sacks) of Class G cement at 15.8 ppg to P&A all bottom perforations from 10938'-11253'. (NOTE: the top perforations have been squeezed but will cover with P&A plug anyway) Pump cement followed by displacement to put TOC at 10838'+/-, calculated displacement is 174.2 bbl. 5. Tag and pressure test the P&A cement plug. 6. Make an explosive cut (Dual End Initiated_Severing__Too!) of the 4-1/2" 12.6# L-80 tubing at about 10300' at a collar. The cut is above the 9-5/8" packer at 10329'. (will not fish anything below tubing cut). 7. Pressure test the 9-5/8" casing to 3500 psi. 8. Ensure that the well is dead and then freeze protect to _+2000' with diesel. Bleed off all pressure, set BPV in the tubing hanger and test to 1000 psi against BPV. Secure well. 9. Remove all electrical lines, well house and flow lines. Level the pad and dig out the cellar. Please provide total well preparation cost on the hand over form. Rig Work: Jim CC: 1. MIRU, Verify well is dead, confirm packoff status from pre-rig. Pull BPV. 2. Circulate the well to remove freeze protection and any trapped gas. Set and test TWC to 1000 psi. ND tree, NU and test BOPE. 3. Pull TWC and circulate well. Pull the 4-1/2" tubing from the cut at approx. 10300'MD. Pull tubing to remove SSSV, set storm packer and replace 9-5/8" packoffs if pre-rig finds them bad. 4. Run and set a 9-5/8" EZSV on Baker 20 setting tool (w/CCL). Set the EZSV near 10000'MD at 2' below a casing collar. (planned KOP is 9980'). 5. Shut in the well and test 9-5/8" and 10-3/4" casing against the EZSV to 3500 psi for 30 minutes. If the casing leaks, an RTTS run will be made to locate and identify the leaking zone for further repairs. 6. PU whipstock assembly for 9-5/8" casing and MWD, RIH on 5" DP to tag the EZSV and set at 30 degrees right of highside. 7. Mill out of the 9-5/8" casing. 8. Trip for build and turn assembly, drill per directional plan to 10'MD into Sag River. 9. Run and cement 7" liner with 150 lap above the whipstock, approximate top of liner 9830' MD. 10. Drill 6" hole to horizontal along directional plan. 11. Run DPC logs at horizontal. 12. Trip for horizontal drilling assy and drill 6" hole to TD (@13973'MD+/-) of the target polygon interval. 13. Run and cement 4-1/2" 12.6#, L-80 liner to TD with 150' lap into the 7", approx, top of liner at 1045O' MD. Test liner top packer and liner to 3500 psi for 30 minutes. Perforate the liner on DP per Asset specifications. Run 4-1/2" 12.6#, LB0 tubing and completion with 3-GLM's. ND stack, NU tree and test. Set BPV ~~.~~ Secure well, release rig.

GommiSSiO" Anchor&ge 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 comple- tion of the fluid disposal process. b) Wells within 200' of the proposed well are: DS 7-14 120' @ surface c) The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. d) Maximum surface pressure is based upon BHP and a full column gas to TD (0.10 psi/ft). e) Based upon previous logs on DS 7, no potential productive zones are anticipated above 4000'TVD.
