Anticipated Surface Pressure:2520 psi Gas Column Gradient (0.1 psi/ft) History K-05 is a natural flow Ivishak producer that developed PC and Tubing leaks in 2019 both @ ~7150' and an additional tubing leak @ ~ 6640' MD. Current Status Not Operable well with PC and Tubing leaks. LLR from TxIA and into PC leak is ~0.4 bpm @ 2400 psi and LLR TxIA is ~0.7 bpm @ 1300 psi. Objective Execute an IA cement repair to seal of the PC and tubing leaks. The proposed TOC the IA is ~4600’ MD. The proposed TOC is ~1591’ TVD below the SC shoe and ~470’ shallower than the estimated top of the UG4 marker @ ~5070’ MD (UG4 is estimated because there is no shallow log on this well and offset well logs were used to estimate it).

Pull LTTP from ~8920’ MD. 2. Set retrievable plug @ ~4600’ MD. 3. PT tubing to verify tubing integrity above 4600’ MD. 4. Pull retreivable plug. 5. Pull DGLV from 8842’ MD. E-Line & Fullbore 1. Set 4-1/2” CBP just below open GLM pocket. 2. Establish LLR of Tubing x IA @ 2400 psi into the PC leak to test CBP (should be ~0.4 bpm which is the LLR @ 2400 psi to the PC leak). 3. Pump diesel down the tubing while taking returns up the IA to confirm circulating rates and pressures through open pocket. 4. Set 4-1/2” cement retainer just above open GLM pocket. Coiled Tubing 1.

Anticipated Surface Pressure: 2520 psi Gas Column Gradient (0.1 psi/ft) History K-05 is a natural flow Ivishak producer that developed PC and Tubing leaks in 2019 both @ ~7150' and an additional tubing leak @ ~ 6640' MD. Current Status Not Operable well with PC and Tubing leaks. LLR from TxIA and into PC leak is ~0.4 bpm @ 2400 psi and LLR TxIA is ~0.7 bpm @ 1300 psi. Objective Repair the well with an IA cement job that is estimated to provide an incremental 230 MBO of production over the next several years. Without an IA cement repair the well has no utility in the foreseeable future. The proposed TOC the IA is ~4600’ MD. The proposed TOC is ~1591’ TVD below the SC shoe and ~470’ shallower than the estimated top of the UG4 marker @ ~5070’ MD (UG4 is estimated because there is no shallow log on this well and offset well logs were used to estimate it). Post-job Evaluation o MIT-T and CMIT-TxIA o CBL to confirm the Top of Cement (TOC) Long-Term Integrity Monitoring o Biennial MIT-T and CMIT-TxIA o Monitor and Record WHPs daily IA Cement for PC/Tbg Leak REV1 Well: K-05 Procedural steps Slickline 1. Pull LTTP from ~8920’ MD. 2. Set retrievable plug @ ~4600’ MD. 3. PT tubing to verify tubing integrity above 4600’ MD. 4. Pull retreivable plug. 5. Pull DGLV from 8842’ MD. E-Line & Fullbore 1. Set 4-1/2” CBP just below open GLM pocket. 2. Establish LLR of Tubing x IA @ 2400 psi into the PC leak to test CBP (should be ~0.4 bpm which is the LLR @ 2400 psi to the PC leak). 3. Pump diesel down the tubing while taking returns up the IA to confirm circulating rates and pressures through open pocket. 4. Set 4-1/2” cement retainer just above open GLM pocket. Coiled Tubing 1. Sting into cement retainer. 2. Pump down CT: ¾ 250 bbls diesel (Freeze-protect for IA after the cement job is in place) ¾ 175 bbls 15.8 ppg Class G cement 3. Un-sting from cement retainer holding ~800 psi of pressure on the CTxTBG backside while POOH to keep cement in place in the IA.

Coiled Tubing 1. Mill out cement retainer, cement, and CBP. E-Line/Slickline (Contingent) 1. If MIT-T above fails, set Nipple Reducer and plug in one of the landing nipples or use LTTP. 2. Set patch across Tubing leak @ ~7150’ MD. 3. Conduct AOGCC witnessed MIT-T to 2100 psi. 4. Pull plug from nipple reducer or pull LTTP. Well Diagnostics & WIE 1.

Subject: NOT OPERABLE: Producers with Sustained Casing Pressure During TAR All, The following producers were found to have sustained casing pressure on the IA during shutdown for turnaround activity. The immediate action is to perform a TIFL on each of the wells to evaluate for IA repressurization. If the wells fail the TIFL, a follow up email will be sent to the AOGCC for each individual well. /K-05D (PTD#2110770) K-12B (PTD#2091430) P-25 (PTD#1970260) Y-20A(PTD#2010250) Y-23B (PTD#2031640) All the wells listed above are reclassified as Not Operable until start-up operations commence and are stable or the well passes a pressure test confirming integrity. After start-up, the wells will be reclassified as Under Evaluation with POP parameters to prevent any over-pressure incidents if integrity has not been confirmed.

Terrie Hubble, 564-4628 Well Number Permit No./Approval No. Drilling Engineer: Eli Vazquez,564-5918 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

Re-install wellhouse, flowline and pull BPV. 2. Generic GLV's 3. Test separator Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg Geo Vis 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: 3" Casing Program: • 2-3/8", 4.7#, L-80, STL 12,512' MD - 8,940' MD ' • A minimum of 13.5 bbls of 15.8 peg cement will be used for liner cementing. (TOC 9,250' 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 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°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 11,420'. • Distance to nearest well within pool—515' to E-209. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCUMCNL logs will be run. Anti-Collision Failures • K-09A PB1 — 238' ctr to ctr distance, plugged back. Well K-09A PB1 found the target sands missing due to due to a combination of faulting and stratigraphic thining; therefore it was plugged back. Hazards • There are no wells on K Pad with H2S readings greater than 100 ppm. ✓ • The maximum recorded H2S level on K pad is 25 ppm on well K-16 on 1/13/2006. Reservoir Pressure • The reservoir pressure on K-05D is expected to be 3,295 psi at 8,800' TVDSS. (7.2 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,415 psi.
