The well was underperforming relative to expectations and just 3 months after the well was drilled, 242’ of additional addperfs were shot in Nov 2019. During the perforating operations coil tagged down at 11478’ and were unable to m ill through the obstruction indicating damaged liner leaving the remaining 335’ of liner inaccessible. Objective: The objective of this procedure is to shoot 500’ of heel perfs from 10150-10650’ that were designated as a future opportunity during the initial completion to get more footage open in Z2A and increase production. This will add rate and provide more uniform drawdown along the lateral. 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. Coil Tubing 1. MIRU Coiled Tubing Unit and spot ancillary equipment. 2. Bullhead 165 bbls of KWF, 8.4 ppg 1% KCl or 8.5 ppg down the tubing to the formation. (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.

Kill well w/ KWF, 8.4 ppg 1% KCl or 8.5 ppg as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 8. Pickup safety joint and 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. 9. Break lubricator connection at QTS and begin makeup of TCP guns and blanks per schedule below. 11-11A Addperf Schedule *HES 2” guns were used to estimate for this job.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

APPROVED BY Approved by:13, COMMISSIONER THE COMMISSION Date: Form 10-401 Revised 5/2017 This permit is valid for 24 v 120 AAC 25.005 Submit Form n Duplicate G� (/ To: Alaska Oil & Gas Conservation Commission From: Zach Browning CTD Engineer Date: April 3, 2019 Re: 11-11A Permit to Drill Request 1�40b p Approval is requested for a permit to drill a CTD sidetrack lateral from well 11-11 with the Nabors CDR2 Coiled Tubing Drilling rig on or around July 1", 2019. Proposed plan for 11-11A: The sidetrack 11-11A will be a "3612' horizontal CST that will kick -out from the 11-11 parent in Zone 4. The CST will establish competitive offtake in the southern portion of the 11-08i waterflood pattern. The sidetrack will be drilled on or around July 1't, 2019. During pre -rig work it is proposed to set a 4-1/2" x 7" Delta whipstock at a kickoff depth of 9238' MD. It is planned to mill the 3.80" window+ 10' of rathole with service coil. The rig will move in, test BOPE and kill the well. The well will drill from Zone 4 to Zone 2 and then remain in Zone 2 for the duration. The proposed sidetrack will be completed with a 3-1/4" x 2-7/8" 13Cr solid liner and cemented in place. The cased hole will be cleaned out, logged (GR/CCL/RPM) and selectively perforated. Pre -Rig Work (scheduled to begin May V, 2019) 1. SL Dummy GLMs. Drift for Whipstock 2. EL Set Delta Whipstock. 3. C Mill XN. Mill Window. 4. V Pre -CTD Tree work. Rig Work (scheduled to begin July 1", 2019) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2539 psi). 2. Drill production section: 4.25" OH, ^3612' (25 deg DLS build, 8 deg DLS lateral planned). 3. Run 3-1/4" x 2-7/8" 13Cr liner to TD. 4. Pump primary cement job: 57.5 bbis, 15.3 ppg Class G, TOC at TOL (`8768' MD)*. 5. Perform Cleanout/Logging run with GR/CCL/RPM. 6. Perforate Wellbore. 2" Millennium guns planned (^'1200', 6spf, planned). 7. Freeze protect well to a min 2,200' TVDss. 8. Close in tree, RDMO. * Approved alternate plug placement per 20 AAC 25.112(1) Post -Rig Work: 1. V: Valve & tree work 2. SL/FB: PT Liner lap. Set LTP/PT LTP (if necessary). Set LGLVs 3. T: Portable TS flowback and well test (if perf 500' or more) Mud Program: • Drilling/Completion: a min EMW of 8.4 ppg KCL with Geovis for drilling (425 psi over -balance). Disposal: • All Class 1& II non -hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must gotOGNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >31 must go to GNI. Hole Size: 4.25" for entirety of the production hole section. Liner Program: • 2-7/8", 6.5k, STL, 13Cr solid liner: • 3-1/4", 6.6k, TCII, 13Cr solid liner: 9650' MD -12,850' MD 8768' MD -9650' MD • A planned 57.5 bbis of 15.3 ppg cement will be used for liner cementing (TOC = TOL at -8768' MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg (425 psi over -balance). • A X -over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional: • See attached directional plan. Maximum planned hole angle is 90% inclination at kickoff point is 18% • Magnetic and inclination surveys will betaken every 30 ft. No gyro will be run. • Distance to nearest property- 29,706' - • Distance to nearest well within pool - 620' - Logging: • MWD directional, Gamma Ray, and Resistivity will be run through the entire open hole section. • GR/CCL/RPM cased hole logs will be run inside the production liner. Perforating: • Perforating: -1200' of perforations, 2', 60 deg random phasing, 6 spf, perf guns. • The primary barrier for this operation: a minimum EMW of 8.4 ppg (425 psi over -balance). • A X -over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti -Collision Failures: • None. All offset wells pass BP anti -collision scan criteria. Hazards: DS 11 is an H2S pad. Max recorded H2S reading on 11-11: 34 ppm on 11/16/18. Max H2S recorded on the pad: 825 ppm on 11-01 on 2/7/16. No planned fault crossings. Lost circulation risk is considered Low. . Reservoir Pressure: • The reservoir pressure on 11 -IIA is expected to be 3419 psi at 8800' TVDSS (7.47 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2539 psi. • Amin EMW of 8.4 ppg for this well will provide 425 psi over -balance to the reservoir.
