We recently set a CIBP at 10,843’ MD and added ~250’ of perforations. After the perfs were shot, the well would not kick off. F-28C was loaded with diesel and a “deep” gas lift design was set. While loading the well with diesel, it was confirmed F-28C has low injectivity, so it is suspected we perforated a low productivity zone. There is a patch across GLM#2 to repair TxIA, so we could not set our S/O below this depth. F-28C was unloaded to the S/O, but it never sustained long term flow, so we would like to add additional perforations to increase the PI. F-28C is twinned with F-27B, a sag rich gas well, so ideally, we would be able to flow F-28C in HP. Objective: The purpose of this procedure is to add additional perforation footage in the well to allow the well to flow as a full-time producer. NOTES: x Well has a patch across GLM #2 at 7741’-7778’ – ID = 2.45”. x Well has DSSSV set with ~2.6” ID. x Needs 1.5” CT Procedure: 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. MIRU 1.5” CTU 2. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHAcannot pull through the brass upon POOH with guns. 3. RIH with GR/CCL & nozzle. Tag plug at ~10,843’ MD. PUH and paint flag for plug/perfs depths. Use plug tag or flag for tie-in at WSL discretion. 4. Bullhead ~200 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.

Prepare for deployment of TCP guns. 6. 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. 7.*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. 8.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.

When drilled the well had known, but unremedied TxIA. A post rig LDL discovered tubing leaks in GLM 2 and the SSSV control lines, which were remedied with a patch and DSSSV respectively. An LTP was also set post rig and its integrity has been confirmed during the post rig LDL. F-28C is twinned with F- 27B, a Sag rich gas well, and usually flow comingled. Objective: The purpose of this procedure is to isolate current perforations and perforate uphole to increase rate and lower the well's TGOR by accessing unproduced sands along the lateral. NOTES: x Well has a patch across GLM #2 at 7741’-7778’ – ID = 2.45”. x Needs 1.5” CT Procedure: Coil – CIBP 1. MIRU 1.5” CTU – include considerations for extended perforating deployment. 2. 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. 3. RIH with GR/CCL and ~1.8” nozzle to ~10,900’. PUH and paint flag for plug/perfs depths. 4. POOH. 5. MU 2-3/8” CIBP. RIH and set at 10,835’. Tag to confirm good set. POOH. 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. Remote gas monitoring for H2S and LELs are required f o isolate current perforations and perforate uphole t Set CIBP & Ext AdPerf Well: F-28C 1. Bullhead ~163 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 perf = 135.7 bbls b. 4-1/2” Tubing/Liner – 8,245’ X .0152bpf = 125.3 bbls c. 2-3/8” Liner – 2655’ X 0.0039 = 10.4 bbl 2. Prepare for deployment of TCP guns. 3. 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. 4.*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. 5.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. Perf Schedule Use 1.56” guns or similar Perf Interval Perf Length Gun Length Weight of Gun (lbs) Run #1 10,400’ – 10,655’255’255’1275 lbs (5 ppf) 6. RIH with perf gun and tie-in to coil flag correlation, consider tagging the CIBP if there is any discrepancy with depths. Pickup and perforate interval per Perf Schedule above. a. Note any tubing pressure change in WSR. 7. 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. 8. Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 9. Review well control steps and Standing Orders with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. 10.
