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 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 TVD 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). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box.

Rig Work (scheduled to begin Feb 20, 2015) 1. MIRU and test BOPE 250 psi low and 3,500 psi high. 2. Mill 2.74" window at 10,260' and 10' of rathole. Drill: 3.25" OH, 2864' (15 deg DLS planned build, 12 deg DLS 3. lateral). 4. Run OH Logs _ 5. Run 2-3/8" liner to from 10,010' to 13,124' MD. Pump primary cement job: 15.9 bbls, 15.3 ppg, TOC at 6. 10,010'. 7. Perform liner cleanout and RPM log. 8. Perform liner lap test. 9. Perforate liner based on log interpretation (-50'). 10. Freeze protect well to 2,500' MD. 11. Set BPV; RDMO. *Approved alternate plug placement per 20 AAC 25.112(i) Post Rig: 1. Re-install well house and attach production lines. 2. Pull TWC. Torque and test tree. 3. Run LTP with 2-7/8" nipple, test LTP 4. Run plug in LTP nipple 5. Run GLV, no screened orifice 6. Set patch 7. CMIT-TxIA, MIT-T 8. Pull plug in LTP Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg PowerVis for milling window and drilling (775 psi over-balance). Disposal: • All Class I & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at - DS4orPad 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: • 3.25" from 10,260' MD to 13,124' MD. • Liner Program: • 2-3/8" 4.6#, HYD 511 L-80, solid liner 10,010' MD — 13,124' MD. • A minimum of 15.9 bbls of 15.3 ppg cement will be used for liner cementing (TOC 10,010' 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 113°, inclination at kick off point is 20°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 25,350'. • Distance to nearest well within pool 648'. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Open hole • Cased hole GR/CCL/RPM logs will be run. Perforating: • SWS 1.56" PJ, 6 spf perf guns, 1 " CSH work string, & 2-1/16" CSH. • 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. Anti-Collision Failures • H-07A fail major risk — no errors (LOTO during rig operation) • D-18A fail major risk - no errors (parent well). Hazards • D-Pad is not an H2S pad. • The lost circulation risk in the D-18B is considered to be medium. Reservoir Pressure • The reservoir pressure on D-18B is expected to be 3160 psi at 8,800' TVDSS. (6.9 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2280 psi. • An EMW of 8.6 ppg for this well will provide 775 psi over-balance to the reservoir.
