A plug was set to isolate the lower 130’ of Z2A perfs then the well has cycled since at low rates. This project looks to use a polymerized gel to squeeze the existing 200’ of open perfs then target 207’ of bypassed Z2A. Liner Lap passed a No flow test in 2021 with plug isolating the lateral.REV1: Fullbore gel squeeze is complete. CT jetted out Gel to CIBP @ 13835’ but was unable to get gun drift through eroded perfs around 13,350’. Depths have been adjusted to deploy extended add perfs up hole. Objective: Fullbore to perform Gel squeeze for GSO. After waiting on gel for 3 days, CT to jet through gel down to CIBP. (COMPLETE). REV1: CT to add 470’ Z1B extended perfs using openhole deployment. Procedure: Fullbore:COMPLETE 1. 2+ days prior to gel squeeze, Perform injectivity Test with 1% KCL or Seawater by loading well with 290 bbls of 1% KCL or seawater followed by crude FP. Record injectivity pressure at 5 bpm with 220 bbls away. Max treating pressure is 2750 psi. 2. Perform Gel Squeeze. Max treating pressure is 2750 psi. a.Load with 220 bbls of 1% KCL or Seawater to flush crude FP formations b.Pump 80 bbls of H2Zero followed by 20 bbls of EquiSeal c.displace with diesel to prevent over displacement. Final pump schedule to follow with volume. 07-13C PTD:211-054 API: 500292033803 REV1 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. RIH with nozzle a. Swap wellbore over to 1% KCL or SW.CT had 1:1 returns post gel cleanout. b. jet/wash through polymerized gel and tag CIBP @ 13,835’ MD.COMPLETE 3. Kill well with 1% KCL or Seawater if needed (system should be closed due to squeezed perfs). Max tubing pressure 2500 psi but attempt to limit pressure as to not breakdown squeezed perforations. 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 = 175 bbls i. 4-1/2” Tubing – 11000’ X 0.0152 bpf = 167 bbls ii. 2-3/8” Liner – 2000’ X 0.0039 = 8 bbls 4. MU and RIH with logging tools and drift BHA: 1.56” dmy gun & nozzle. 5. Flag pipe as appropriate per WSS for add perf run. 6. POOH and freeze protect tubing as needed. 7. Confirm good log data. 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. b.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. 07-13C PTD:211-054 API: 500292033803 REV1 Perf Schedule (Updated for REV1) *HES 1.56" Millenium guns were used to estimate for this job and calculate gun weights.

A plug was set to isolate the lower 130’ of Z2A perfs then the well has cycled since at low rates. This project looks to use a polymerized gel to squeeze the existing 200’ of open perfs then target 207’ of bypassed Z2A. Liner Lap passed a No flow test in 2021 with plug isolating the lateral. Objective: Fullbore to perform Gel squeeze for GSO. After waiting on gel for 7 days, CT to jet through gel then add 207’ of Z2A perfs using openhole deployment system. Procedure: Fullbore: 1. Perform injectivity Test with 1% KCL or Seawaterby loading well with 290 bbls of 1% KCL or seawater. Record injectivity pressure at 5 bpm with 220 bbls away. Max treating pressure is 2750 psi. 2. Perform Gel Squeeze. Plan is to squeeze 80 bbls of H2Zero followed by 20 bbls of EquiSeal into open perfs, then displace with diesel to prevent over displacement. Final pump schedule may be adjusted based off injectivity and operational limitations. 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. 07-13C PTD:211-054 API: 500292033803 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. RIH with nozzle a. Swap wellbore over to 1% KCL or SW b. jet/wash through polymerized gel and tag CIBP @ 13,835’ MD. 3. Kill well with 1% KCL or Seawater if needed (system should be closed due to squeezed perfs). Max tubing pressure 2500 psi but attempt to limit pressure as to not breakdown squeezed perforations. 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 = 175 bbls i. 4-1/2” Tubing – 11000’ X 0.0152 bpf = 167 bbls ii. 2-3/8” Liner – 2000’ X 0.0039 = 8 bbls 4. MU and RIH with logging tools and drift BHA: 1.56” dmy gun & nozzle. 5. Flag pipe as appropriate per WSS for add perf run. 6. POOH and freeze protect tubing as needed. 7. Confirm good log data. 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. b.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. Perf Schedule *HES 1.56" Millenium guns were used to estimate for this job and calculate gun weights.

Pickup and perforate interval per Perf Schedule above. c. 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.

Well 07-13B is a horizontal coil sidetrack drilled in June 2002 targeting Zone 1B sands. HOT was not tagged but is believed to be 5-10' below the well. There was 640' of Zone 1B initially perforated. Within 3 months, the oil rate fell and the GOR reached marginal GOR. A Borax/MCNUSTP was run in Jan 2003 to identify the gas source. The borax pass showed no channels, and the liner lap was not leaking. The well continued to cycle for the next 4 years with degrading ontime. A CIBP was set at 12065' CTMD on 3/13/07 for a GSO. An additional 85' of Zone 1B perforations were added in April 2009, but the well reached MGOR within 2 months. Based on the 2003 GOC and the very short rate buzz from the 2009 additional perforations, uphole lenses were not pursued. In January, 2011, a caliper was run. The tubing is in good-to-fair condition with a max well penetration of 36%. The liner is also in good condition. The MIT-IA passed to 3,000 psi and MIT-OA passed to 2,000 psi. The proposed plan for 07-13C is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around June 10,2011. The existing perforations will be isolated by a packer whipstock, as well as the primary cement job. The sidetrack, 07-13C, will exit the existing 2-3/8" liner and kick off in the Ivishak and land in Zone 2A. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. CTD Sidetrack Summary Pre-Rig Work: (scheduled to begin April 21, 2011) 1. 0 MIT-IA to 3000 psi; MIT-OA to 2000 psi. 2.
