Dc20 Alaska Oil & Gas Conservation Commission 333 West 7th Avenue, Suite 100 31 a,,Jr11 Anchorage, AK 99501 Re: Duck Island Unit Well Renaming Request SCANNED `"!' 0 1 2016 Dear Commissioner Foerster, Hilcorp Alaska, LLC (HAK) requests a change to the naming convention of Duck Island Unit wells to remove the unused suffixes at the end of each well name. Well names currently include a forward slash "/"followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/134" (PTD# 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet. Sincerely, Wyatt Rivard Well Integrity Engineer Hilcorp Alaska, LLC CC Dave Roby Victoria Loepp .

Endicott well 3-25A/N-24 is presently a suspended well following,'"' an unsuccessful sidetrack attempt in 2001. The well is planned to b~.sidetracked to a new bottom hole location as a conventional producer targeti, pg the Kekiktuk K2A' lower subzone reservoir. The sidetrack is currently scheduled for Doyon 15 beginning around February 15th. The pre-rig work for this sidetrack is planned to begin no later than December 1,2002. The pre-rig P&A operations plan is to cap the 7" bridge plug (13,488'), and 7" liner top (13,141') with a CTU set cement plug~/The drilling rig would then move on, pull the tubing hanger, mill a window at +/-11500' in the 9-5/8" casing, drill an 8-1/2~, hole to the new bottom hole location, run and cement a 4-1/2" liner, and run a 4-1/2" completion.' See attached schematics for details. Sidetrack and Completion Procedure Summary Pre-Ri.q Work: * Notify the field AOGCC representative with intent to plug and abandon * 1. Pressure test the tubing hanger seals to 5000 psi for 30 minutes. Completed 10/10/2002. Tubing hanger seals tested to 5000 psi for 30 minutes. All tubing hanger Iockdown screws were functioned. 2. Pressure test the 9-5/8" FMC casing hanger packoff to 3000 psi for 30 minute~.Completed 10/10/2002. Casing hanger packoff tested to 3000 psi for 30 minutes 3. RIH with CTU and set a P&A cement plug using 15.8 lb/gal c~.t. ~lse ad,e,,quate ceme~nt volume to fill the 7" liner from the bridge plug at 13488' up to/1305P.!i..in the 9-5/8 casing. 4. Tag and document top of cement. ~''''' 5. Displace well to seawater. Freeze protect the well to 2000' Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 6. Prep the well house, cleanout cellar, and rig down the flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. · Rig Operations: 1. MIRU Doyon 15. 2. Pull BPV. Set TWC & test from below. 3. Nipple down tree. Alignment marks should be made before removinq the old tree. Nipple up and test BOPE to 250 / 5000 psi. Pull TWC. 4. Pull and lay down tubing hanger and 2 joints of 4-1/2" tubing. 5. RIH with full gauge whipstock mill on 5" drill pipe to 12000'. Circulate out freeze protect. 6. RU e-line. Run and set a 9-5/8" bridge plug to position top of whipstock at +/- 11500'. 7. MU 9-5/8" whipstock and milling assembly and RIH with 5" DP. Orient and set whipstock on bridge plug. Mill window in 9-5/8" casing. 8. MU 8-1/2" PDC drilling assembly including MWD/GR. RIH to window. 9. Kick-off and drill the 8-1/2" hole section as per directional plan to TD at +/-14305" MD (10,338' TVD). Trip for triple combo LWD prior to the Kekiktuk. Condition hole for running liner, spot liner running pill, and POOH. 10. Run and cement a 4-1/2", 12.6 Ib/ft 13 Cr-80 production liner. Release from liner and set liner top packer. Test wellbore to 2000 psi to verify liner top packer is set. Displace well to seawater. 11. Run 4-1/2", 12.6 Ib/ft 13 Cr-80 gas lift completion. Space-out tubing so the WLEG is inside the 4-1/2" liner tie-back sleeve. RU slickline and make drift run thru liner hanger to verify proper spaceout. 12. Drop ball/rod & set packer. Test the tubing to 3000 psi and annulus to 3000 psi for 30 minutes. 13. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. 14. Freeze protect to 2000' MD and secure the well. 15. Rig down and move off. Post-Riq Work: 1. RU slickline. Pull the ball and rod / RHC plug from 'XN' nipple below the production packer. Install gas lift valves. 2. RU e-line. Perforate -50' of Kekiktuk interval with 2-7/8" guns.

After drilling to 14429' MD, a trip was made to change the bit. While RIH through the existing 7" exit window (13571- 83' MD), the drilling BHA got stuck at 13623' MD. After unsuccessfully attempting to jar the BHA free, the proposed forward operation is as follows: Procedure. 1. POH. LD fishing assembly and 6" BHA. 2. MU 6" mill tooth bit, 7" casing scraper, 400' of 3-1/2" drill pipe, XO, 9-5/8" casing scraper, I stand 5" drill pipe, drilling jars and 5" drill pipe to surface. 3. Stage in hole to 11000' MD, circulating at maximum rate. Work pipe up and down while circulating. a. Pump weighted Bara fiber sweeps to ensure hole is clean. 4. After reaching the 7" liner top with the 6" bit, circulate btms up prior to going into the 7" liner. 5. Wash entire length of the 7" liner to the top of the fish @ 13494' MD. 6. CBU. Ensure wellbore is clean. 7. Close 5" pipe rams and establish injection rate. 8. After injectivity test, displace well to 9.4 ppg brine. 9. POH and LD clean out assembly. If unable to establish injection rate in step #8, go to step #15. 10. If able to establish injection, MU cement retainer on drill pipe. 11. RIH with retainer. Tag top of fish at 13494' MD, PU 4 ft and set retainer at 13490' MD. 12. Establish injection rate. Sqz 25 bbls of 15.8 ppg cement below retainer. (open hole volume: 30 bbls) 13. Unsting from the retainer and test casing to 2000 psi. 14. POH with drill pipe. Go to step #19. 15. RU e-line unit. 16. MU 7" CIBP on e-line setting tool. RIH and set CIBP at 13490' MD (4 ft above the top of the fish). 17. POH and rig down e-line. 18. Pressure test casing to 2000 psi for minutes. 19. Based on BP and co-owner approval, a second sidetrack is an option. This directional plan would be included with the Sundry notice. 20. If the well is suspended, the following operations would be completed: a. The top 1500' of the well would befreeze protected with diesel b. Run 2 jts of 4-1/2" L80 and the Cameron tbg hanger. RUN in LDS. Test void area. c. Set TWC. Test to 500 psi through tbg spool. d. ND BOPE. NU DH tree. Test tree to 3500 psi e. Remove TWC and install BPV. f. Move rig to the Endicott 3-15/K-33 Rig workover. g. The 3-25A/N-24 would be included on the Endicott drilling schedule after 11/1/01.

The permit to redrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does 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 by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sincerely, ~ Daniel T.

The sidetrack, 3-25/N-24, will kick off in the upper Kekiktuk and target the K2B. Planned TD will be 15752' MD, (10,171' TVD). This sidetrack will be conducted in two phases. Phase 1: Set Whipstock, Down squeeze cement, mill window. Planned for 2-/15/01 - 2/20/01. · E-Line will set the whipstock at approx. 13,500' · Service coil will down squeeze approx. 22 bbls cement to shut off existing perfs. Phase 2: Drill and Complete sidetrack: Planned for 3/15/01. Doyon Rig #15 will be used to mill the window, drill and complete the directional hole as per attached plan. The sidetrack will be completed with a cemented liner. The well will be sidetracked within the Kekiktuk Formation. Shown below are the interval tops within the Kekiktuk.
