The original perfs produced until 2015 when a plug was set for GSO of the toe perfs. Production again went HGOR in late 2019. Subsequently, a plug was set to isolate all existing perfs and add 186’ perfs up hole. A 2023 Plug mill was performed in conjunction with a toe oil lens add perf – production was competitive for 6+ months before becoming MGOR. In March 2024, all perfs were isolated with a plug, then 295’ of Z2B perfs were added. The LTP was changed out to suppress gas rates in April 2024. The well became HGOR in late May 2024. Now we look to move up hole. Objective: CT Set CIBP to isolate all existing perfs, add 284’ of Z2B perforations using the open hole deployment system. Procedure: Coiled Tubing 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. x 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. 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. Load well with 1% KCL/SW down TBG. 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. add 284’ of Z2B perforations 06-24B EAP PTD:212-190 API: 500292082202 a.

MU and RIH with logging tools and drift BHA: 2” dmy gun & nozzle. 4. Flag pipe as appropriate per WSS for adperf/CIBP runs. 5. POOH and freeze protect tubing as needed. 6. Confirm good log data. 7. RIH w/ 2-7/8” CIBP, set @ 10,750’. 8. At surface, prepare for deployment of TCP guns. 9. 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 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. 10.*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. 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. 11.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. Only 1 run, which will be 295’ of loaded guns (no blanks). Perf Schedule Use 2” Maxforce guns or similar Perf Interval (RUN 1) Perf Length Gun Length Weight of Gun (lbs) 5.6 lbs/ft 10388 - 10672 284’284’1590 12. RIH with perf gun and tie-in to coil flag correlation. Pickup and perforate interval per Perf Schedule above. a. Note any tubing pressure change in WSR. 13. After perforating, PUH to top of liner or into tubing tail to ensure debris doesn’t fall in on the guns and stick the BHA. Confirm well is dead and re-kill if necessary before pulling to surface. 14. Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 15. Review well control steps and Standing Orders with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. 16. Ensure safety joint and TIW valve assembly are on-hand before breaking off lubricator to LD gun BHA. 17. RDMO CTU. 18. RTP or FP well.

The original perfs produced until 2015 when a plug was set for GSO of the toe perfs. Production again went HGOR in late 2019. Subsequently, a plug was set to isolate all existing perfs and add 186’ perfs up hole. An increasing GOR trend indicated a potential leaky LTP in 2021 and a PPROF was run for confirmation. Subsequently, the LTP was reset and a plug was set to shut off gas. A 2023 Plug mill was performed in conjunction with a toe oil lens add perf – production was competitive for 6+ months, but now the well is near marginal GOR. Only 1/3 rd of the lateral has been played out. The plan forward is to move uphole. Objective: CT Set CIBP to isolate all existing perfs, add 295’ of Z2B perforations using the open hole deployment system. Procedure: Coiled Tubing 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. x 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. 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. Load well with 1% KCL/SW down TBG. 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. 06-24B PTD:212-190 API: 500292082202 a.

Kill well w/KWF, 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. 10.*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. 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. 11.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. Only 1 run, which will be 295’ of loaded guns (no blanks).

Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 15.
