Brief Well Summary: CTD sidetrack completed in 2011 as a zone 1 well. Well has not had a lot of production since being shutin near the end of 2015 due to high GOR. Objective:This program will involve slickline pulling the dreamcatcher and performing a MIT-T/liner lap integrity test, followed by CT isolating the lower liner with a CIBP and performing 2 extended perforating runs to add a new producing interval up-hole. Procedure: Slickline & Fullbore 1. Pull dreamcatcher from 10,287’ 2. Load well with 200 bbls of dead crude 3. Set test plug in deployment sleave at 10,355’ 4. Pressure test liner lap to 2000 psi for 5 min and determine LLR or pressure loss rate if it doesn’t hold solid – contact/send results to OE. 5. Pull test plug from deployment sleave 6. RDMO. If liner lap passed the pressure test then proceed with the following CT steps to plug and perforate. If the PT failed then contact OE for plans to set LTP. Coiled Tubing 1. MU GR/CCL with ~2.25” JSN drift (NS Bridge plug 278-210 is 2.1” OD). RIH to ~12,000’. Flag pipe and pull tie-in log. a.

Correlate with SLB Memory CNL 6/13/11(see attached log – Jewelry Log Pass). Correct flag and send to Jeff Nelson or OE. 3. MU NS 278-210 Bridge Plug or similar. RIH. 4. Set CIBP at 11,760’MD. 5. POOH. Plug & Ext Perf E-23C PTD:211-053 Coil – Extended Perforating – If liner integrity test passed then proceed with 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. 6. 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. 7. Bullhead 1.5X wellbore volume - 254 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.

Use flag from CIBP drift if possible. If needed MU and RIH with GR/CCL in carrier with 2.25” JSN. f. Flag pipe as appropriate per WSS for adperf g. POOH and freeze protect tubing as needed. h. Confirm good log data. 9. At surface, prepare for deployment of TCP guns. 10. 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. 11.*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. i.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. 12.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.

On 07/13/22 Slickline was attempting to perform more troubleshooting on the past failed CMIT-TxIA and when another CMIT-TxIA was re-attempted, it passed to 2575 psi. A MIT-T was also performed on 07/13/22 and passed to 2575 psi. The passing MITs confirm two competent well barriers and the well meets operability criteria. However, due to the fact no remedial work was performed in between the failing and passing CMIT-TxIAs, the well will be placed Under Evaluation for further monitoring. Plan Forward: 1. Ops: POP well 2. Well Integrity: Monitor for IA re-pressurization/further diagnostics as needed Please respond if in conflict.

On 02/21/20 Slickline set a TTP and performed a failing CMIT-TxIA. A subsequent MIT-T passed to 2,599 psi. The failed CMIT-TxIA indicates a failure in one or more well barriers. The well is now classified as NOT OPERABLE and will remain secured with the TTP. The Anchorage Engineer will evaluate for repair. Please respond with any questions.

The well has dummy gas lift valves installed and known TxIA communication that is manageable by bleeds. The NOL excursion was reported shortly after the well was put on production, it had previously been shut in since 03/17/19. The anomalous NOL excursion indicates a failure in one or more well barriers and the well will now be classified as UNDER EVALUATION to prove barriers. Plan forward: 1.

Submit In Duplicate ORIGINAL To: Alaska Oil & Gas Conservation Commission From: Matthew Ross 0 b p CTD Engineer Date: April 4, 2011 Re: E-23C Permit to Drill request Approval is requested for a permit to drill a CTD sidetrack from well E-23B. E-23B is a 2000 horizontal CST in Zone 1A and a RWO in July 2008 repaired Tx1A communication.The well was brought online in July 2008 and ever since has high GOR.At current operating conditions, E-23B is uncompetitive with no remaining wellwork options to return it to production. The proposed plan for well E-23C is to sidetrack out of the E-23B 7" liner with a Coiled Tubing Drilling rig on or around May 10, 2010. The existing perforations will be isolated by a down squeeze cement job pre CTD operations. The sidetrack will exit the 7" liner in Zone 2 and drill a 4.125"hole in the target zone IA sands. CTD Sidetrack Summary Pre-Rig Work: (scheduled to begin May 1, 2010). 1. F MIT IA& OA. 2. S Dummy WS drift to 10,950' MD. ✓ 3. E Set 4-1/2"x7" WS at 10,850' MD. 4. C Mill XN profile at 10,350' MD. 5. C Down squeeze 6bbls of cement past whipstock. 6. V PT MV, SV, WV. 7. D Bleed gas lift and production flowlines down to zero and blind flange. 8. 0 Remove wellhouse, level pad. 9. V Set TWC -24hr prior to rig arrival. C-L3B Rig Work: (scheduled to begin on May 10, 2011) 1. MIRU and test BOPE to 250 psi low and 3500 psi high. Pull TWC. 2. Mill 3.8" window at 10,850' MD and 10' of rathole. 3. Drill Build: 4.125" OH, 30' (9°/100). 4. Drill Build: 4.125" OH, 700' (16°/100). 5. Drill Lateral: 4.125" OH, 1973' (12°/100). 6.

Run MCNL/GR/CCL log. • 10. Perforate 1200ft. 11. Freeze protect well, set BPV and RDMO: Post-Rig Work: 1. Re-install wellhouse and FL's. 2. Apply furmanite wrap to well head. 3. Run generic GLV's. 4. ASRC flowback. Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg QuikDriln mud for milling window and drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 4.125" Casing Program: • 3-1/2" STL, 9.3 pounds per foot, L-80 solid liner- 10,320' MD to 10,350' MD. • 3-3/16"TCII, 6.2 pounds per foot, L-80 solid liner- 10,350' MD to 11,000' MD. • 2-7/8" STL, 6.4 pounds per foot, L-80 solid liner- 11,000' MD to 13,573' MD. V • A minimum of 34 bbls 15.8 ppg cement will be used for liner cementing. • TOC planned at 10,650' MD. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. ✓ • The annular preventer will be tested to 250 psi and 3500 psi. Directional • See attached directional plan. Maximum planned hole angle is 94.4°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. v • Distance to nearest property— 14,995 ft. • Distance to nearest well within pool—685ft to E-24B Logging • MWD directional, Gamma Ray and resistivity will be run over all of the open hole section. • Cased hole GR/CCL/MCNL logs will be run. Anti-Collision Failures E-14A— 1166 ft. ctr-ctr; Shut in due to TxIA communication. • E-19B— 109 ft ctr-ctr; Will be shut. Hazards • Three mapped fault crossings at 11,300' MD at 11,400' MD and at 11,850' MD. • The maximum recorded H2S level on E pad was 130 ppm on well E-102 on 9/25/2009./ - • Lost circulation risk is considered moderate for this well due to the planned fault crossing. Reservoir Pressure • The reservoir pressure on E-23C is expected to be 3296 psi at 8,800' TVDSS. (7.2.2pg equivalent). • Maximum expected surface pressure with gas(0.10 psi/ft)to surface is 2416 psi.
