The well is currently SI due to high GOR. The most recent intervention was with coil milling 2x CIBPs January 2023 to capture flush production from multiple sets of perfs in the toe. Strong flush was observed, and it sustained full-time production for 5 months. Following that the well showed decent cycle characteristics. After a year and a half of cycling, the subsurface team has decided to move on and set a plug & extended perforate a 110’ of net perforations over a 200’ gross interval. The 10’ of heel perfs are right above the 22N shale and will be left open and evaluated in the future to be isolated. Objective: Set CIBP & Perforate 110’ net over a 200’ gross interval. 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 11,340’) Contact Finn Oestgaard & Jeff Nelson for tie-in correlation. 2. Set CIBPmid element @ 11,340’ Setting in 3-1/4” liner 6.6#, ID = 2.850” (will need to pass through LTP @ 9,826’ w/ ID=2.313”) Coil –Extended Perforating Notes: x Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. 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. CCT Extended Perforating Well:D-24A Page 22 of 111 2. Bullhead 1.2x wellbore volume ~190 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.

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 standing orders 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. a.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.

Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 10.

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 a AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

The D-24A sidetrack will exit through the existing 7" liner and kick off in Zone 2, and target Zone 2A Reserves. The proposed sidetrack is a —1,550' horizontal Ivishak Zone 2 producer, which will access a —39 acre reserves target northeast of D-pad. The ter twill be completed with a 3-1/2"X 3-1/4" L-80 liner which will be fully cemented and perforated. 5tie I-ra ` Rig Work(scheduled to begin January 21st, 2015) 1. MIRU and test BOPE 250 psi low and 3,500 psi high. (MASP 2,341 psi) 2. Mill 3.80"window and 10' of rathole. 3. Drill build: 4.25" OH, 475' (25 deg DLS planned). 4. Drill lateral: 4.25" OH, 1,075' (12 deg DLS planned). 5. Run 3-1/2"x 3-1/4" L-80 liner leaving TOL at—9,950' MD. 6. Pump primary cement job: 24 bbls, 15.8 ppg, TOC at TOL—10,285' MD* 7. Perform liner cleanout and RPM/GR/CCL log. 8. Perform liner lap test to 2,400 psi 9. Perforate liner based on log interpretation (-300'). 10. Freeze protect well to 2,500' MD. 11. Set TWC; RDMO. Post-Rig Work: 1. Re-install wellhouse, flowline and pull TWC. 2. Set liner top packer with slickline if needed* 3. Set GLV's. *Approved alternate plug placement per 20 AAC 25.112(i) Mud Program: • Milling/drilling: 9.5 ppg PowerVis for milling window and drilling (1126 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 3atDS6. • 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: • 4.25" From 10,680' MD to 12,230' MD • Liner Program: • 3-1/2", 9.3 lb/ft, L-80, STL liner 9,950' MD - 10,660' MD • 3-1/4", 6.2 lb/ft, L-80, TC-Il Solid liner 10,660' MD - 12,230' MD • A minimum of 24 bbls of 15.8 ppg cement will be used for liner cementing (TOC 10,285' 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 99°, inclination at kick off point is 21°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—21,600'. • Distance to nearest well within pool —460'. Logging: • MWD directional, gamma ray and resistivity will be run over all of the open hole section. • Cased hole GR/CCL/RPM logs will be run. Perforating: • SWS 2", 6 spf, perf guns, 1-1/4" CSH work string, &2-3/8" PH6. • 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. Anti-Collision Failures: • D-30C Center-to-center 342'. Well will be shut-in and locked out for the D-24A sidetrack. Hazards: • D-pad is not considered an H2S pad. • D-24 had 18 ppm H2S on 2/28/2012. • The lost circulation risk in D-24A is considered to be medium with one fault crossing planned. - Reservoir Pressure: • The reservoir pressure on D-24A expected to be 3,222 psi at 8,800' TVDSS (7.04 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,342 psi. • An EMW of 8.4 ppg for this well will provide 622 psi over-balance to the reservoir.
