Anticipated Surface Pressure:2430psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP:2250 psi (Taken on 3/21/2019) Min ID:1.78” ID LTP at 11298’ MD Max Angle:94 Deg @ 13190’ Brief Well Summary: A 2016 sidetrack into Z1A and Z1B, C-31C was completed with 425' of toe perfs and flowed full time until mid 2018 when the well began to reach marginal GOR. The well was cycled once before developing a tubing leak and being SI in early 2019. The well was recently POP’d under evaluation but is no longer cycling well and is ready for next stage of perfs. The goal of this program is to move to the next stage of perforations to return well to economic GOR. Prior to plugging and extended add perfs on C-31C, a large ID tubing patch will be installed and tested to restore tubing integrity. Objective:Utilize CTU to isolate existing perforations then surface deploy TCP guns with CTU to add new perfs and improve fluid rates. Notes Regarding Wellbore Condition: x TXIA communication confirmed at .3 BPM at 2400 psi through tubing leak observed at ~8854’ MD x CMIT-TxIA passed to 2609 psi on 4/10/2019 Sundry Procedure (Approval Required to Proceed): Eline 1.

RDMO (PCE) Patch, Plug and Add Perf C-31C PTD:216-134 Coil Tubing Note: The well will be killed and monitored before making up the initial perfs guns. This is generally done during the drift/logging or plug set 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.

Planned operations: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around December 1st 2016. A plug will be set pre -rig above the C-31 B production liner isolating the open perforations. Cement will be squeezed into the IA below the production packer to allow for a dual string exit. The cement will be placed between 11,359' MD and 11,280' MD (shown on the proposed schematic attached). Then a 3-1/2" monobore whipstock will be set pre -rig to allow for a 2.80" 3.5" x 7" dual string exit. The well kicks -off in lower Zone 4, and will land and target reserves in Zone 1A/1 B above the HOT. The proposed sidetrack is a 2500' horizontal Ivishak producer to be completed with a 2-3/8" L-80 solid liner, cemented in place and selectively perforated. The open parent perf intervals are below the KOP and will be isolated via the plug set pre -rig as well as the liner cement job or liner top packer.* Rig Work scheduled to begin December 1St, 2016 1.

O: NWKO IV.N omL ( Mud Program: • Drilling/Completion: a min EMW of 8.4 ppg KCL with Geovis for drilling (434psi 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" for production hole section from 11,328' MD to 13,775' MD. Liner Program: • 2-3/8", 4.7 Ib/ft, H511, L-80 solid liner: 11,308' MD — 13,775' MD ' • A planned 17.5 bbls of 15.3 ppg cement will be used for liner cementing (TOC = TOL at 11,308' MD). ✓ • The primary barrier for this operation: a minimum EMW of 8.4 ppg (434 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 900 (TD), inclination at kick off point is 30°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property — 29,820' (North) • Distance to nearest well within pool — 950' (C -32D) Logging: • MWD directional, Gamma Ray, and Resistivity will be run through the entire open hole section. • Cased hole GR/CCL/RPM logs will be run inside casing (post -rig). Perforating: • Perforations: —300' of perforations, 1.56", 60 deg random phasing, 6 spf, pert guns. - Anti -Collision Failures: • None. All offset wells pass BP anti -collision scan criteria. Hazards: j • C -pad is not an H2S pad. Latest H2S reading on the C-31 was 23ppm on 2/4/15. • No planned fault crossings. The lost circulation risk in C -31C is considered to be LOW. Reservoir Pressure: • The reservoir pressure on C -31C is expected to be 3,410 psi at 8,800' TVDSS (7.45 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,530 psi. • A min EMW of 8.4 ppg for this well will provide 434 psi over -balance to the reservoir.

Planned operations: Drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around December 1 st 2016. A plug will be set pre -rig isolating the C-31 B perforations. A —500' IA cement squeeze is planned to provide a cement packer since the planned sidetrack kicks off above the existing production packer. This IA squeeze is not needed to fix any integrity issue, but is needed for multiple dual string exits planned, both this one and ones in the future. The TOC (10,500' MD) is planned to provide pressure integrity in the IA above all possible sidetrack locations. A 2.80" window will be milled off the 3-1/2" whipstock set pre -rig. The well kicks -off in lower Zone 4, and will land and target reserves in Zone 1A/1 B above the HOT. The proposed sidetrack is a 2500' horizontal Ivishak producer to be completed with a 2-3/8" L-80 solid liner, cemented in place and selectively perforated. The open parent pert intervals are below the KOP and will be isolated via the plug set pre -rig as well as the liner cement job or liner top packer.* RigWork scheduled to begin December 1St, 2016 1.

O: NWKO Mud Program: • Drilling/Completion: a min EMW of 8.4 ppg KCL with Geovis for drilling (434psi 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" for production hole section from 11,165' MD to 13,668' MD. Liner Program: • 2-3/8", 4.7 Ib/ft, H511, L-80 solid liner: 11,100' MD — 13,668' MD • A planned 17.5 bbls of 15.3 ppg cement will be used for liner cementing (TOC = TOL at 11,100' MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg (434 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 900 (TD), inclination at kickoff point is 290 . • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property — 29,820' (North) • Distance to nearest well within pool — 780' (C -32D) - Logging: • MWD directional, Gamma Ray, and Resistivity will be run through the entire open hole section. - • Cased hole GR/CCL/RPM logs will be run inside casing (post -rig). Perforating: • Perforations: —300' of perforations, 1.56", 60 deg random phasing, 6 spf, pert guns. Anti -Collision Failures: • None. All offset wells pass BP anti -collision scan criteria. Hazards: • C -pad is not an H2S pad. Latest H2S reading on the C-31 was 23ppm on 2/4/15. • No planned fault crossings. The lost circulation risk in C -31C is considered to be LOW. Reservoir Pressure: • The reservoir pressure on E -07B is expected to be 3,410 psi at 8,800' TVDSS (7.45 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,530 psi. . • A min EMW of 8.4 ppg for this well will provide 434 psi over -balance to the reservoir.
