Anticipated Surface Pressure:2439psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:2400 psi (Taken on 5/18/18) Min ID:1.78” ID @ 9179’ MD Max Angle:95 Deg @ 10422’ Reference Log: SLB MCNL 6/26/11 Brief Well Summary: 15-05B was drilled in 06/11 and completed with 1180' of perforations in Z1A/Z1B (100' of Z1B perfs at the toe). By 2012, the well reached marginal GOR and in 08/12 a PPROF was run. The decision was made to abandon the original set of perforations by setting a CIBP and adding 90' of Z1A perfs in the heel. Multiple attempts to PoP the well failed (this can also be an indication that the LTP is holding). In 10/13 the CIBP was milled. As a result the well was online 80% of the time for a year, then reached marginal and did not exhibit significant recharge. Objective: The objective of this program is to set a CIBP to isolate the toe to reduce gas in a 2-3/8" liner and add heel perfs to increase well production on time. Cerberus Modelling suggests making TD with ~200’ of 1.56” guns w/ 1.5” coil tubing (.109 wall thickness). SFD 1/13/2021 Set CIBP and Add Perf 15-05B PTD: 2110570 Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the initial perfs guns. This is generally done during the drift/logging run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. Coil Tubing 1. MIRU Coiled Tubing Unit and spot ancillary equipment. 2. Bullhead 220 bbls of 8.4 ppg 1% KCl or 8.5 ppg seawater down the tubing to the formation. (This step can be performed any time prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.) a. Wellbore volume to top perfs = ~145 bbls 3. MU and RIH with GR/CCL logging tools and ~1.75” nozzle. Tag PBTD prior to logging OOH. 4. POOH and confirm good data. 5. Contact OE prior to perforating for final approval of tie-ins. 6. Freeze protect tubing as needed. 7. RIH w/ 2 3/8” CIBP (~OD of 1.75”) and set at ~12,070’. 8. POOH and at surface, prepare for deployment of TCP guns. 9. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 10. Pickup safety joint and TIW valve and space out before MU guns.Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. 11. Break lubricator connection at QTS and begin makeup of TCP guns and blanks per schedule below. 15-05B Addperf Schedule Perf Interval Perf Length Gun Length Including Blanks 10409-10471 62 18810505-10536 31 10566-10597 31 12. RIH with perf gun and tie-in. Pickup and perforate intervals per Perf Schedule above. POOH. a. Note any tubing pressure change in WSR. 13. POOH. Stop at surface to reconfirm well is dead and hole is full. 14. Review well control steps with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. * Standing orders flow char incuded with this sundry request. *See note above regarding kill methods if pressure observed on surface after perforating.

Item 1 a: 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).

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 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. `'. .-rel �/ � ♦''om . ioner DATED this 1?2<lay of April, 2011. cc: Department of Fish 86 Game, Habitat Section w/o encl.
