In 2018, 62’ of Sag was added with a negligible effect. Since mid-2021, the well has been a cycle well with moderate recharge characteristics. The well is currently shut in for HGOR. Earlier this year, a plug isolating the toe was milled to re-access 970’ of Z1A sands shut in since March 2018 with minimal success. There was minimal flush and the cycling behavior deteriorated. This intervention is to shut off the 970’ of Z1A toe perfs that were re-accessed earlier this year. It is suspected that they may be connected to potential fractures connecting to gas and then perforate an additional 219’ of Z1A infilling footage between perfs shot in 2018. Objective: Set CIBP & Perforate 219’ of net charges over a 272’ interval in Z1. Procedure: Coiled Tubing –Drift/Tie-In & Plugset 1. MU Tie-In/Drift BHA (configuration per WSL discretion), RIH and flag for plug set (target set depth 11,462’) During plug mill February 2024, no noted obstructions or tight spots, pumped a little slick while RIH.

CCT Extended Adperf Well:F-23B The well will be killed and monitored before making up the initial perf 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. 1. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHA cannot pull through the brass upon POOH with guns. 2. Bullhead 1.2x wellbore volume ~187 bbls 1% KCL/SW down tubing. Max tubing pressure 2500 psi. (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 Ivishak perf (10,915)=156 bbls b. 4-1/2” Tubing – 9,483’ X .0152 bpf = 144 bbls c. 3-1/2” Liner – 589’ X 0.0087 bpf = 5 bbls d. 3-1/4” Liner – 843’ X 0.0079 bpf = 7 bbls 3. At surface, prepare for deployment of TCP guns. 4. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/ KKWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain hole fill taking returns to tank until lubricator connection is re-established. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 5.*Perform drill by picking up safety joint with 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. e.At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 6.Break lubricator connection at QTS and begin makeup of TCP guns per schedule below. Constantly monitor fluid rates pumped in and fluid returns out of the well. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow.

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).

MIRU and test BOPE 250 psi low and 3,500 psi high. (2577 psi MASP). 2. Mill 3.80" window and 10' of rathole. 3. Drill Production section: 4.5" OH, -2640' (12° deg/100 planned) 6. Run 3-1/2" x 3-1/4" L-80 solid liner to leaving TOL 9,500' MD. 7. Pump primary cement TOC/TOL -9500' MD, 35 bbls of 15.8 ppg cement planned. 8. Perform liner cleanout with mill, motor and RPM/GR/CCL log. 9. Perforate liner based on log interpretation 10. Freeze protect well to 2500' MD 11. Set TWC, RDMO Post-Rig Work: 1. Re-install wellhouse, flowline and pull TWC. 2. Set GLV's Mud Program: S S • Milling/drilling: 8.4 ppg PowerVis for milling window and drilling (589 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 >11 must go to GNI. Hole Size: • 4.5" From 10,080' MD to 12,270' MD Liner Program: • 3-1/2", 9.4 lb/ft, L-80, STL, solid 9,500' MD-10,080' MD • 3-1/4", 6.6 lb/ft, L-80, TCII, solid 10,080' MD — 12,270' MD. • A minimum of 35 bbls of 15.8ppg of cement will be used for liner cementing. (TOC 9,500'MD) • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • 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 102°, inclination at kick off point is 52° • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 7,900'. • Distance to nearest well within pool — 500'. Logging: • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. Anti-Collision Failures: • E-13A-E-13A will be shut-in and LO/TO for drilling F-23B. • F-27A-3-1/4" Liner Plugged and abandoned with KB Packer Whipstock no need to shut-in. Hazards: • F pad is considered a H2S pad. Well F-24 had 160 ppm H2S on 5/15/2007. • Most recent H2S level on F-04B is 12 ppm recorded on 9/25/2014. • The lost circulation risk in F-23B is considered to be low, with planned two fault crossings. Reservoir Pressure: • The reservoir pressure on F-23B expected to be 3340 psi at 8995' TVDSS. (7.14 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,440 psi. • An EMW of 8.4 ppg for this well will provide 589 psi over-balance to the reservoir.
