The well has been secured with a tubing plug at 11332’ and a failing CMIT-TxIA was performed on 12/13/22. Subsequent leak detection logging identified TxIA + PC leak. At this time, the well is classified as NOT OPERABLE and will remain shut in until well barriers are restored. Please call with any questions or concerns.

The well then failed a TIFL later on 12/4/22 indicating afailure of one or more barriers. IA pressure exceeded MOASP at 2373 psi on 12/4/22. The well is now classified as UNDER EVALUATION and is on the 28-day clock for diagnostics. Plan Forward: 1. Slickline: Set DGLV 2. DHD: Re-TIFL 3.

Item 23. Attached supplemental records 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 Rem 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 coresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071.

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.

Proposed plan for 15-27B: The sidetrack 15-27B will be a 2136' horizontal CST that will kick -out from the 15-27A Ivishak producer. The CST will be drilled to the north and will target remaining oil potential that has not yet been recovered in existing completions in Zone 1. The well will utilize an open hole Autonomous Inflow Control Device (AICD) completion to manage the high gas volumes that are expected from a GD well. The sidetrack will be drilled on or around June 1", 2019. The rig will move in, test BOPE and kill the well. The 3.80" window will be milled off a 4-1/2" monobore whipstock set pre - rig. The well kicks -off in Zone 1, geo steer low in section and potentially dip into the stratigraphic BSAD. The proposed sidetrack will be completed with 2-3/8" x 2-7/8" x 3-1/2" 13CR liner with an AICD and swell packer completion. Rig Work (scheduled to begin June 1", 2019) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2500 psi). 2. Mill 3.80" Window + 10' of rathole. 3. Drill production lateral: 4.25" OH, ^2136' (12 deg DLS planned). ' 4. Run 3-1/2" x 2-7/8" x 2-3/8" 13Cr liner with Swell Packers and AICDs to TD. 5. Freeze protect well to a min 2,200' TVDss. 6. Close in tree, RDMO. s Post -Rig Work: 1. V: Tree work as needed. 2. SL: Drift and Set LTP. Set and test LTP 3. FB: PT LTP. 4. CT: RPM. N2 Lift. 5. T: Test wel I. Set KO Gas Lift Design for potential PBGL. Mud Program: • Drilling/Completion: a min EMW of 8.4 ppg KCL with Geovis for drilling (430 psi over -balance). Disposal: • All Class I & II non -hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >ll must go to GNI. Hole Size: • 4.25" for entirety of the production hole section. Liner Program: • 2-3/8", 4.7#, HYD 511, 13Cr liner with AICDs and Swell Packers: 15,175' MD -16,510' MD • 2-7/8", 6.5#, STL, 13Cr solid liner: 14,390' MD -15,175' MD • 3-1/2", 9.3#, STL 13Cr solid liner: 11,310' MD -14,390' MD • The primary barrier for this operation: a minimum EMW of 8.4 ppg (430 psi over -balance). ✓ • A X -over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional: • See attached directional plan. Maximum planned hole angle is 96', inclination at kickoff point is 86'. • Magnetic and inclination surveys will betaken every 30 ft. No gyro will be run. • Distance to nearest property -17,165' ' • Distance to nearest well within pool —615' (15-29A) Logging: MWD directional, Gamma Ray, and Resistivity will be run through the entire open hole section. Gamma Ray / CCL / RPM log planned post -rig through the entire production liner. Perforating: • No perforating is planned for this well. AICD/Swell Packer completion. Anti -Collision Failures: • None. All offset wells pass BP anti -collision scan criteria. Hazards: • DS 15 is considered an H2S pad. Most recent H25 reading on 15-27A: 12 ppm (09/28/18). Maximum H2S reading on the pad: 50 ppm on 15-21A (2/24/01). • Lost circulation risk on 15-27B is considered Low. Reservoir Pressure: • The reservoir pressure on 15-27B is expected to be 3370 psi at 8700' TVDSS (7.45 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2500 psi. • A min EMW of 8.4 ppg for this well will provide 430 psi over -balance to the reservoir.
