However the reservoir once again contained gas, and the well will not be completed at this location. The well penetrated the Kuparuk reservoir approximately -147' high and LWD logs showed signs of gas in the reservoir. Plans are to plug back and sidetrack to a Kuparuk target approximately 1400' to the southwest of the S-113A penetration. Below is an outline of the proposed plug back and sidetrack operations. Also enclosed is a schematic of the existing well bore and proposed plug- back. If you have any questions or require any additional information, please contact me at 564-5521. Scope Ria Operations: 1. RIH to TD at 12,640' MD with 5" DP cement stinger. Circulate and condition well for cementing operations. Spot a balanced 15.8 ppg cement P&A plug from TD to +/-11,840' MD (-450' above the Top Kuparuk Reservoir). Plug volume should be based upon an equivalent hole diameter of 10.4" throughout this section (84 bbls total). Pull above cement plug and circulate DP clean. 2. Spot a 11.0 ppg heavy mud spacer from top of cement P&A plug at -11,840' MD to -9450' MD. Pull DP up to 10,200' MD and circulate out any excess heavy mud spacer above this point. 3. Spot a 10.7 ppg Form-A-Plug pill (cross-linked polymer pill) from 10,200' to -9925' MD to act as a base for the upcoming cement kick-off plug. Pull DP above top of plug and circulate any excess pill out of DP. Pull to shoe and wait on Form-A-Plug to set (-6 hrs). 4. RIH to -9800' and wash down looking for top of plug. Once top of plug is verified, condition mud as required for spotting the cement kick-off plug. 5. Spot a 15.8 ppg cement kick-off plug from 10,000' to 9600' MD (estimated depths). Plug volume should be based upon an equivalent hole diameter of 11.4" throughout this section (51 bbls total). Pull DP above plug and circulate OP clean. POOH. 6. PU 9-7/8" drilling assembly and RIH.

Kick-off and drill the 9-7/8" hole section as per directional plan to TO @ :t13,595' MD (7245' TVO). POOH. 7. Run and cement the 7", 26# production casing as required to cover all significant hydrocarbon intervals (no significant hydrocarbons were seen in the Ugnu or West Sak intervals and therefore, plans are to bring cement -1200' above top Kuparuk formation only). Displace the 7" casing with seawater during cementing operations. Once cement has had adequate time to set, freeze protect the 7" x 10-3/4" annulus as required. 8. RU slick-line and run gauge ring / junk basket to PBTD. 9. Run a 4-1/2",12.6#, L-80 TC-II completion and space-out tubing tail -50' MD above top Kuparuk. S-113A Application for Sundry ) ) 10.

The permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

In accordance with 20 AAC 25.005(t), all records, data and logs acquired for the pilot hole must be clearly differentiated in both name (name on permit plus PH) and API number (50 -70/80) from records, data and logs acquired for well (name on permit). ANNULAR DISPOSAL Please note that an disposal of fluids generated. . . INTO ANNULUS OF ANOTHER WELL ON SAME PAD <-> SPACING EXCEPTION DRY DITCH SAMPLE Enclosed is the approved application for permit to drill the above referenced well. The permit is approved subject to full compliance with 20 AAC 25.055. Approval to perforate and produce is contingent upon issuance of a conservation order approving a spacing exception. (Companv Name) will assume the liability of any protest to the spacing exception that may occur. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones.
