On 9/5/17 slickline set a tubing tail plug and performed a failing MIT-T, and passing CMIT-IA to 2,500psi.. The failed MIT-T confirms integrity loss of the primary well barrier. At this time the well is reclassified as Not Operable and will remain shut in and secured with a down hole tubing plug. The production engineer will evaluate the well for future utility.

On 9/5/17 slickline set a tubing tail plug and performed a failing MIT-T, and passing MIT-IA to 2,500psi.. The failed MIT-T confirms integrity loss of the primary well barrier. At this time the well is reclassified as Not Operable and will remain shut in and secured with a down hole tubing plug. The production engineer will evaluate the well for future utility.

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

Kyle Raese bp CTD Engineer t0,1 Date: January 15, 2015 Re: G-16B Permit to Drill Request Approval is requested for a permit to drill a CTD sidetrack lateral from well G-16A by the Nordic 2 Coiled Tubing Drilling rig on or around March 1, 2015. The G-16B sidetrack will perform a dual-string exit through the existing 3-1/2" tubing and 7" liner. Kick-off will occur in the Sag River formation and target Zone 1B reserves. The proposed sidetrack is a —2,850' horizontal Ivishak Zone 1B producer which will access a —35 acre reserves target southwest of G-Pad. The lateral will be completed with a 2-3/8" L-80 liner which will be cemented and perforated. Rig Work(scheduled to begin March 1, 2015) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,337 psi). 2. Pull TWC and kill well. 3. Mill 2.80"window and 10' of rathole. - 4. Drill build: 3.25" OH, 950' (16 deg DLS planned). 5. Drill lateral: 3.25" OH, 1900' (12 deg DLS planned). 6. Run 2-3/8" L-80 liner leaving TOL at—9325' MD. 7. Pump primary cement job: 16.7 bbls, 15.3 ppg, TOC at—9,325' MD.* 8. Perform liner cleanout(if necessary) and RPM/GR/CCL log. 9. Perform liner lap test. 10. Perforate —500' liner based on log interpretation. • 11. Freeze protect well to 2,500' TVDss. 12.

T Test separator. *Approved alternate plug placement per 20 AAC 25.112(i) Mud Program: • Well kill: 8.4 ppg brine (627 psi over-balance) • Milling/drilling: 9.5 ppg PowerPro(1130 psi over-balance) Disposal: • All Class I & 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 go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 must go to GNI. Hole Size: • 3.25" from 9,375' MD to 12,225' MD - Liner Program: • • 2-3/8", 4.7 lb/ft, L-80, TH 511 liner with cementralizers 9,325' MD - 12,225' MD • A minimum of 16.7 bbls of 15.3 ppg cement will be used for liner cementing (TOC 9,325' MD). • The primary barrier for this operation is 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 hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and 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 97°. Inclination at kick off point is 21°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—20,075'. • Distance to nearest well within pool—460'. Logging: • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/RPM logs will be run. Perforating: • 1.56" HSD 1606 PJ HMX, 6 spf perf guns, 1" CSH work string &2-1/16" CSH. • The primary barrier for this operation is 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 hole. Anti-Collision Failures: • D-07 Center to center: 1,168'—Abandoned leg • G-15C Center to center: 627' — Producer to be shut-in • G-16 Center to center: 0' — Parent wellbore at KOP • G-16A Center to center: 0' — Parent wellbore at KOP • G-21 Center to center: 24' — Producer(A/C failure occurs in abandoned section) • G-21 PB1 Center to center: 12' —Abandoned plugback Hazards: • G-Pad is not an H2S pad. • G-16A had 20 ppm H2S on 3/17/2014. • The lost circulation risk for G-16B is considered to be medium with two planned fault crossings. Reservoir Pressure: • The reservoir pressure on G-16B is expected to be 3,217 psi at 8,800' TVDss (7.03 ppg equivalent). • Maximum expected surface pressure with gas (0.10'psi/ft) to surface is 2,337 psi. • An EMW of 8.4 ppg for this well will provide 7 psi over-balance to the reservoir.

In accordance with 20 AAC 25.005(f), all records, data and logs acquired for the pilot hole must be clearly differentiated in both well name Pilot Hole ( PH) and API number (50- - - - ) from records, data and logs acquired for well (name on permit). The permit is approved subject to full compliance with 20 AAC 25.055. Approval to produce / inject is contingent upon issuance of a Spacing Exception conservation order approving a spacing exception. (Company Name) Operator assumes the liability of any protest to the spacing exception that may occur. All dry ditch sample sets submitted to the AOGCC must be in no greater Dry Ditch Sample than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Please note the following special condition of this permit: Production or production testing of coal bed methane is not allowed for Non-Conventional (name of well) until after (Company Name) has designed and Well implemented a water well testing program to provide baseline data on water quality and quantity. (Company Name) must contact the AOGCC to obtain advance approval of such water well testing program. Regulation 20 AAC 25.071(a) authorizes the AOGCC to specify types of well logs to be run. In addition to the well logging program proposed by (Company Name) in the attached application,the following well logs are Well Lo ,n also required for this well: gg g Requirements Per Statute AS 31.05.030(d)(2)(B) and Regulation 20 AAC 25.071, composite curves for well logs run must be submitted to the AOGCC within 90 days after completion, suspension or abandonment of this well.
