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 1a: 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 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITeM 23: 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 28: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain).

Hole size: 4.125" (bi-center bits used) Casing Program: fully cemented liner • 3-1/2", L-80 9.3# STL 8,925' - 8,955' and • 3-3/16", L-80 6.2# TCII 8,955' and - 10,900' and • 2-7/8", L-80 6.16# STL 10,900'md - 11,860' and • A minimum of 33.7 bbls 15.8 ppg cement will be used for liner cementing. • TOC planned at 9,150' Existing casinq/tubinp Information 13-3/8", L-80 72#, Burst 5380, collapse 2670 psi 9-5/8", L-80, 47# Burst 6870, collapse 4750 7.625", L-80 29.7#, Burst 6890, collapse 4790 psi 4-1/2", 13-CR 12.6#, Burst 8430, collapse 7500 psi Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 90 deg at 10,584. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line - 4,200 ft. • Distance to nearest well within pool - 764 ft. (E-04 C~ 9,950') Logging • MW D directional, Resistivity and Gamma Ray will be run over all of the open hole section. • Cased hole MCNUGR/CCL will be run. Hazards • The maximum recorded H2S level on E pad was 20 ppm on well E-25. • One planned fault crossing, calculated risk of lost circulation low. Reservoir Pressure • The reservoir pressure on E-36A is expected to be 3,423 psi at 8,800' TVDSS. (7.48 ppg equivalent) • Max. expected surface pressure with gas (0.10 psi/ft) to surface is 2,543 psi.
