Anticipated Surface Pressure:2,513psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:300 psi Min ID:2.31” ID BKR SS @ 9190’ MD Max Relevant Angle:36 Deg @ 8667’MD Brief Well Summary: P-11 was drilled in 1991 and a lateral was added in 2015. In 2018 the well showed TxIA communication. While performing diagnostics, slickline could not work beyond an obstruction below the GLM at 9121’MD. Coil tubing attempted to mill the obstruction without success. As the well still has TxIA it has been determined that a tubing swap should be performed to reinstate integrity and return this well to production. Notes Regarding Wellbore Condition: x The 7-5/8” production casing passed CMIT-TxIA to 2,600 psig on 4/26/2015. A current MIT-IA is not possible due to restriction in tubing. x As the tubing is collapsed below the first GLM, Ivishak perfs will not be isolated during the RWO. Fluid and BOP will be primary and secondary barriers. x Estimated Production Casing Cement top based on pumped volumes is 3900’MD Objective: Pull the existing 4 ½” L80 tubing out of the well and replace with 13 Chrome tubing. Achieve a passing MIT-IA & MIT-T. Primary completion objective is to remove obstruction to regain reservoir access for future perforations. If fishing tubing below collapse is unsuccessful, future tool access will not be available, but reservoir communication will be maintained and the well will be completed with the contingent completion plan (Contingent schematic attached) Pre-Sundry Work: DHD 1. Cycle LDS’s 2. PPPOT-T 3. PPPOT-IC Sundry Procedure (Approval required to proceed): Eline 4. Pull DSSSV Plug from 2109’MD 5. Cut tubing @ ~ 9112’ 6. Circulate well to 8.4 ppg 1% KCL or equivalent (Freeze protect with diesel on T & IA if needed before next step) Valve Shop/Ops 7. Kill well if needed with additional 8.4 ppg 1% KCL or equivalent. Keep fill on IA 8. Check WHP and Confirm well is dead RWO Procedure WELL: P-11 / P-11L1 PTD:191-029 / 215-022 9. Set and test TWC. Test from above to 3000psi then perform rolling test from below attempting to catch 500psi (anticipating 5bpm loss at this pressure) – confirm no pressure through TWC into tree 10. Nipple Down Tree and tubing head adapter. Inspect lift threads. 11. NU BOPE configured top down, Annular, 2-7/8” x 5-1/2” VBRs, Blinds and flow cross. RWO 12. MIRU Thunderbird #1 Rig. Throughout operations, maintain hole fill in IA with KWF to maintain a barrier throughout operations. If the hole cannot hold a column, maintain fill at 30bbl/hr. 13. Test BOPE to 250psi Low/3,000psi High, annular to 250psi Low/2,500psi High (hold each ram/valve and test for 5-min). Record accumulator pre-charge pressures and chart tests. A. Perform Test per Thunderbird #1 BOP test procedure. B. Notify AOGCC 24 hrs in advance of BOP test. C. Confirm test pressures per the Sundry Conditions of approval. D. Test the 2-7/8” x 5-1/2” VBR’s with 4-½” and 2-7/8” test joints. Test the Annular preventer with a 2-7/8” test joint. E. Submit to AOGCC completed 10-424 form within 5 days of BOPE test. 14. Rig up lubricator and test to 3000psi. Pull TWC with lubricator and circulate well STS to KWF. Monitor well to confirm dead. LD Lubricator and TWC. 15. MU landing joint or spear, BOLDS and pull hanger to the floor. PU weights are expected to be ~101K 16. With 4 1/2” tubing at floor, circulate bottoms up if needed. 17. LD Tubing to cut. Confirm and Strap cut joint length, and eccentricity of pipe to latch with overshot. 18. PU workstring and overshot. RIH to tubing cut, engage tubing stub and attempt to release from K-22 anchor per fishing hand on location. If unable to release, contact OE for plan forward. a. If unable to fish remaining tubing the contingency completion (schematic attached) will be utilized. b. If any milling was done to fish, a cleanout/magnet/junk basket BHA may be ran. 19. POOH with remaining 4-1/2” Tubing, 45KB LTP packer, 3-1/2” Tubing and 2-7/8” tubing with SS and LD. 20. Pick up 7-5/8” retrievable test packer, RIH and set packer below primary or contingency packer setting depth (whichever applies). MIT-IA to 3,000-psi for 30 charted minutes. Leak hunt if necessary. 21. LD workstring and 7-5/8” test packer. 22. Run 4 ½” 13Cr tubing with stacker packer completion as detailed on proposed schematic. 23. Land Hanger and load IA with corrosion inhibited 8.4 ppg 1% KCL or equivalent. 24. Drop ball and rod and set packer with 3,500psi pump pressure. 25. Perform MIT-T to 3,000 psi and MIT-IA to 3,000 psi for 30 charted minutes. 26. Shear valve in upper GLM. No Freeze protect needed if valve shop is lined up for tree work. 27. Set TWC. Test from below to 3000psi 28. Rig down Thunderbird #1. May want to consider spotting reservoir mud if difficulty maintaining fluids at surface. mgr Notify AOGCC if contingency plan is required.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item la: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift, Rod Pump, Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box.

This permit to drill does not exempt you from obtaining additional permits or an approval 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 AOGCC 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 AOGCC 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 an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Sincerely, 01 Daniel T. Seamount, Jr. Commissioner I DATED this 1! day of February, 2015.
