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 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. 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).

Pump primary cement job: 16.0 bbls, 15.8 ppg, TOC at 9,000' MD. No Yes 7. Perform liner cleanout and RPM/CCL log. No Yes 8. Perforate liner based on log interpretation (-50'). No Yes 9. Freeze protect well to 2,500' MD. No Yes 10. Set BPV and RDMO. No Yes Post-Rig Work: 1. Re-install wellhouse, flowline and pull BPV. 2. Set GLV's. 3. Set liner top packer with slickline as needed. 4. ASRC flowback/well test. Mud Program: • Milling/drilling: 8.5 ppg PowerVis for milling window and drilling (607 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 3atDS6. • 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: •4-1/4" From 8,855' MD to 10,390' MD • Liner Program: • 3-1/2"9.3#, L-80, ST-L solid liner 8,085' MD—8,600' MD • 3-1/4"6.6#, L-80, TC-Il solid liner 8,600' MD—fault crossing (approx. 10,000' MD) • 2-7/8"6.4#, L-80, ST-L solid liner Fault Crossing (approx. 10,000' MD)— 10,390' MD . • A minimum of 16 bbls of 15.8 ppg cement will be used for liner cementing (TOC 9,000 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 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 97.2°, inclination at kick off point is 2.85°. ' • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 11,028'. • Distance to nearest well within pool E-35B—850'. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • • Cased hole RPM/CCL logs will be run. Perforating: • 2.0", 6 s f. P erf guns, 1-1/4"CS H & CS H work string • • 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 run in hole. Anti-Collision Failures 1 • No anti-collision failures. Hazards / • E Pad is an H2S pad. • Most recent H2S level on E-16 is 10 ppm recorded on 10/05/2012. •The lost circulation risk in the E-16A is considered to be medium. Reservoir Pressure . •The reservoir pressure on E-16A is expected to be 3,439 psi at 9,200'TVDSS. (7.19 ppg equivalent). • Maximum a cte surface pressure with gas(0.10 psi/ft)to surface is 2,519 psi. / •An EMW 8.4 pp for this well will provide 579 psi over-balance to the reservoir.
