The well is a gravity drainage Z1A lateral. The well struggles to sustain flow, even with gaslift. We would like to perforate unswept Z1A and mill both CIBP’s. Objective:Mill plugs and perforate remaining unswept Z1A interval Procedure Coiled Tubing 1. MU 2-1/8” milling assembly with 2-1/4” mill. Tag CIBP at 13,250ft Mill up CIBP and push to next plug at 13,875ft. Mill up second plug. If unsuccessful pick up 2-3/8” shoe and burn over and recover plug(s). Drift to 14,615ft. Note: 2.377” ID at 11,486 ft (liner crossover). 2. MU drift BHA with GR/CCL in 2-1/8” carrier, drift to 12,250ft. 3. Correlate with attached log information. a. Correct flag and send to OE for confirmation. 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. 2. Bullhead 1.2x wellbore volume ~220 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 = 176.4 bbls b. 4-1/2” tubing – 10,923’ X .0152 bpf = 166 bbls c. 3-1/2” tubing 10,923’ – 11,486’ X .0087bpf=4.9 bbls d. 2-7/8” liner 11,486’ – 12,430’ (top perf)’ X .0058bpf=5.5 bbls Extended Add Perfs 11-30A PTD: 214-174 3. At surface, prepare for deployment of TCP guns. 4. 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. 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. 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. Perf Schedule Use 2.00” Millennium guns or similar (2.2” swell in liquid) Perf Interval (tie-in depths) Total Gun Length Weight of Gun (lbs) Run #1 12,143’ - 12,238’95’~530 lbs (5.58 ppf) 7. 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. 8. 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. 9. Pump pipe displacement while POOH. Stop at surface to reconfirm well is dead. Kill well if necessary. 10. Review well control steps and Standing Orders with crew prior to breaking lubricator connection and commencing breakdown of TCP gun string. 11. Ensure safety joint and TIW valve assembly are on-hand before breaking off lubricator to LD gun BHA. 12. RDMO CTU. 13. Turn well over to Operations POP.

The logged light oil column was 31' TVD and 1,425' of initial perforations were added on Feb 3rd, 2015. The well was first POP'd with ASRC on April 14th, 2015 with a 24 hour test showing 1,275 bopd; 41 bwpd; 31.6 mmscfd of gas; 25,000 GOR; and 3.1% WC @ 1,014 psi FTP. However, in October 2015 a CIBP was set to isolate the toe perfs that were bringing in gas due to their close proximity to the GOC making it uncompetitive. After the CIBP was set to isolate the gas coming from the toe and allowed the perforations in the belly of the liner to have more drawdown, the well POP’d at 748bopd, 58bwpd, 3.4mmscfd of gas and GOR of 4,600. However since Oct 2015, there has been very little intervention and rates have declined steadily to 283 bopd; 20 bwpd; 25 mmscfd of gas; 88,000 GOR; and 6.6% WC @ 834 psi FTP in March 2021. Objective: The objective of this program is to increase the performance of the well by re-perforating the existing zones by shooting deeper penetrating guns than originally shot and mitigating fines migration over the last 6 years that may be contributing to the reduction in GFR. Also, the results of this re-perf will be evaluated for additional FURy well re-perf opportunities in the area that have seen GFRs decrease in recent years. An acid stimulation was reviewed for this job, but it was substantially more expensive than using extended addperf deployment and wasn’t economic. Slickline 1. MIRU Slickline Unit and spot ancillary equipment. 2. RIH with a 2-1/8” sample bailer to deviation and collect sample if possible. If sample is collected please note in AWGRS and notify OE. (This step is at the WSL’s discretion.) Sundry Procedure (Approval Required to Proceed): Note: 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. * o increase the performance of the well by re-perforating the existing zones by shooting deeper penetrating guns t FURy Addperfs 11-30A PTD: 214174 Coil Tubing 1.
