The original toe and mid lateral perfs were plugged in 2023 and 125ft of Z2A was added. They are currently uncompetitive. Objective: The objective of this procedure is to plug the current perforations and shoot additional Z2A perforations from 11,686-12,062 (376ft). Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the initial perfs guns. 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 200 bbls of KWF, 8.4 ppg 1% KCl or 8.5 ppg 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 perf = 171 bbls b. 4-1/2” Tubing – 10,252’ X .0152bpf = 156 bbls c. 3-1/2” Liner - 85’ X .0087bpf = 0.8 bbls d. 3-3/16” Liner - 1422’ x .0079 = 11.2 bbls e. 2-7/8” Liner – 521’ X .0058bpf = 3 bbls 3. MU and RIH with logging tools and drift BHA to resemble 2” dmy gun. Run past 12,175’ctmd and log OOH. 4. POOH and confirm good data. 5. Freeze protect tubing as needed. 6. RIH and set 2-7/8” CIBP at ~12,175ft. (Note min ID is X nipple at 10,282’). Verify tubing is full and pressure test to 500-psi. Plug & Perf Procedure 02-21B PTD:211-033 7. At surface, prepare for deployment of TCP guns. 8. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/KWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 9.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. 10. Break lubricator connection at QTS and begin makeup of TCP guns and blanks per schedule below. 02-21B Addperf Schedule *HES 2” maxforce guns were used to estimate for this job. If unavailable, use another vendor as needed. 11. MU lubricator and RIH withperf gun and tie-in to coil flag correlation. Pickup and perforate interval per Perf Schedule above. POOH. a. Note any tubing pressure change in WSR. 12. POOH. Stop at surface to reconfirm well dead and hole full. 13.

A MIT-T and MIT-IA both passed to 3500 psi on September 22, 2015. The passing tests confirm two competent barriers in the wellbore. The well is reclassified as Operable. • Well status is Operable • Annuli are fluid packed • A SSSV is not required Please use caution while placing the well on production due to fluid packed annuli and the potential for annular fluid expansion.

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).

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.

(TOC 10750'MD) 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 2,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 95 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line—26500' • Distance to nearest well within pool —880' Anticollision Summary • 01-20 center to center distance is 885.89'. 01-20 current status is shut-in oil producer. Logging • MWD directional, Gamma Ray, and Resistivity will be run over all of the open hole section. • A cased hole GR/CCUCNL log will be run. Hazards • The maximum recorded H2S level on DS A is 24 ppm on well 02-27A (4/23/2010). • Lost circulation risk is Low. The planned trajectory does not cross any mapped faults, but it does cross over a graben feature that is mapped at BSAD. Subsiesic faulting associated with the graben could cause there to be lost circulation while drilling. Reservoir Pressure • Reservoir pressure is estimated to be 3,249 psi at 8,800'ss (7.1 ppg EMW). Maximum surface pressure with gas (0.10 psi/ft) to surface is 2,369' psi.
