Item 23. Attached supplemental records should show the details of any multiple stage cementing and the location of the cementing tool. Item 24. If this "it 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_ Item 31. Pursuant to 20 AAC 25.070, attach to this forth: well schematic diagram, summary of daily well operations, directional or inclination survey, and other tests as required including, but not limited to: core analysis, paleontological report, production or well test results.

Proposed plan for 16-20A: Well 16-20A is proposed as a pattern rotation side-track targeting unswept Zone 4A & 4B hydrocarbons. It will receive injection support from wells 03-04 and 16-02, as well as the planned MIST injector 16-14C. The side-track 16-20A will be a "1560' horizontal CST that will kick -out from the 16-20 parent in Zone 4. This well is planned to be drilled on or around February 1", 2019. During pre -rig work a 7" whipstock will be set at "'10,355' MD. The rig will move in, test BOPE and kill the well. A 3.80" window + 30' of rathole will be milled. The well will cross through Zone 4 and Zone 3 to target resources in 4A and 4B. The proposed side-track will be completed with a 3-1/4" x 2-7/8" 13Cr solid liner, cemented in place and selectively perforated (post rig). Rig Work (scheduled to begin February 151, 2019) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2762 psi). 2. Mill 3.80" Window and rathole. 3. Drill production section: 4.25" OH, 1560'. 4. Run 3-1/4" x 2-7/8" 13Cr liner to TD. 5. Pump primary cement job: 25.7 bbis, 15.3 ppg Class G, TOC at TOL (9870 MD) •. 6. Freeze protect well to a min 2,200' TVDss. 7. Close in tree, RDMO. ' Approved alternate plug placement per 20 AAC 25.112(i) Post -Rig Work: 1. V: Pull TWC (if set) 2. FB: liner lap test, PT LTP 3. SL: Set Baker LTP w/ PTSA stinger (if needed), set LGLVs, drift for coil perfjob. 4. C: Perforate (-200'). Mud Program: • Drilling/Completion: a min EMW of 8.4 ppg KCL with Geovis for drilling (201 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: • 4.25" for entirety of the production hole section. Liner Program: • 2-7/8", 6.5#, 13Cr solid liner: 10,800' MD —11,914' MD • 3-1/4", 6.6#, 13Cr solid liner: 9870' MD —10,800' MD • A planned 26.9 bbls of 15.3 ppg cement will be used for liner cementing (TOC = TOL at 9870' MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg (201 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 110', inclination at kickoff point is 28°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 12,690' • Distance to nearest well within pool — 165'(16-14B) Logging: • MWD directional, Gamma Ray, and Resistivity will be run through the entire open hole section. Perforating: • Perforating will be completed post rig (-200'). Anti -Collision Failures: • None. All offset wells pass BP anti -collision scan criteria. Hazards: • DS -16 is considered a H2S pad. Recent H2S reading on 16-20: 160 ppm (5/17/2018). Max recorded on the pad: 500 ppm on 16-15 (5/27/2012). • No fault crossings planned. • Lost circulation risk on 16-20A is considered Low. Reservoir Pressure: • The reservoir pressure on 16-20A is expected to be 3643 psi at 8800' TVDSS (7.96 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2763 psi. - • A min EMW of 8.4 ppg for this well will provide 201 psi over -balance to the reservoir.
