Anticipated Surface Pressure: 2,470psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP: 2,400 psi (Taken on 11/24/14) Min ID: 2.313” ID Nipple reducer @ 9,479’ MD Max Angle: 93 Deg @ 10,989’ Brief Well Summary: 18-08b is a Z1A lateral producer that was CTD sidetracked in 2012 and stayed online until 2015. An LDL Indicated 3 tubing leaks in addition to the two patches. It is not worth patching again. We will now pursue a RWO to replace the L-80 tubing. Objective: Pull the existing 4 ½” L80 tubing out of the well and replace with 4-1/2” 13 chrome tubing. Achieve a passing MIT-IA & MIT-T. Pre RWO work: SL - Pull 45KB patches Pull nipple reducer Secure well with 3.81” PX plug at 9,347’ DHD – MIT OA – 1,200 psi CMIT-TxIA to 3,000-psi after resecuring well, run eline LDL if failing. Cycle LDS’s PPPOT-T to 5,000psi PPPOT-IC to 3,500pdi EL – LDL if necessary Cut tubing @ ~ 9,268’ Circulate well to 8.5 ppg 1% KCL w/ diesel FP on T & IA DHD - Bleed WHP’s to 0 Valve Shop - Set and test TWC Nipple Down Tree and tubing head adapter. Inspect lift threads. NU BOPE configured top down, Annular, 2-7/8” x 5-1/2” VBRs, Blinds and integral flow cross RWO 18-08b PTD: 2120130 Proposed RWO Procedure: 1. MIRU Thunderbird #1 Rig. 2. Test BOPE to 250psi Low/3,000psi High, annular to 250psi Low/2,500psi High (hold each ram/valve and test for 5-min). Record accumulator pre-charge pressures and chart tests. A. Perform Test per Thunderbird #1 BOP test procedure. B. Notify AOGCC 24 hrs in advance of BOP test. C. Confirm test pressures per the Sundry Conditions of approval. D. Test the 2-7/8” x 5-1/2” VBR’s with 4 ½” and 2-7/8” test joints. Test the Annular preventer with a 2-7/8” test joint. E. Submit to AOGCC completed 10-424 form within 5 days of BOPE test. 3. Pull TWC 4. MU landing joint or spear, BOLDS and pull tubing hanger to the floor. PU weights are expected to be ~130K. Circulate bottoms up. 5. Pull 4 1/2” tubing. 6. Run 4 ½” Chrome tubing with stacker packer completion as detailed on proposed schematic. 7. Land Hanger and reverse in corrosion inhibited 8.5ppg 1% KCl. 8. Drop ball and rod and set packer with 3,500psi pump pressure. 9. Perform MIT-T to 3,000 psi and MIT-IA to 3,000 psi for 30 charted minutes. 10. Shear valve in upper GLM 11. Set TWC 12. Rig down Thunderbird #1. Post rig valve shop work 1. ND BOPE 2. NU tree and tubing head adapter. 3. Test both tree and tubing hanger void to 500psi low/5,000psi high. 4.

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 la: 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: TheAPI number reportedA must14 digits(ex: 50-029-20123-00-00). to be to OGCC be d g is Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND 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. 1 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 MC 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 MC 25.071.

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 Commission 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 Commission 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 a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

Mud Program: • Well kill: 8.4 ppg seawater/ brine. • Milling/drilling: 8.6 ppg Geo-VIS for milling window and drilling (-732 psi overbalance). Disposal: • All Class !! drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 4-1/8" 9,630' and— 12,838' and Liner Program: Solid, cemented, and perforated completion. • 3-1/4", L-80, 6.6 lb/ft TC-II liner 9,500' and — 10,250' and • 2-7/8", L-80, 6.5 lb/ft STL liner 10,250' and— 12,838' and • Planned 34 bbls of 15.8 class G cement will be used for liner cementing (assuming 4-1/8" hole size to TD and 20% excess in open hole). • TOC planned at 9,500' MD. • The primary barrier for this operation: a minimum EMW of 8.4 ppg. / • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in the 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 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 99°, inclination at kick off point is 18°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 39,000' and (South). • Distance to nearest well within pool — 1,500' from 18-07A. Anti-Collision • 18-08A 1' (ctr—ctr distance) Status: Parent Wellbore. • 18-08A PB1 1' (ctr—ctr distance) Status: Plugged and Abandoned. • 18-27C 54' (ctr—ctr distance) Status: Plugged and Abandoned.
