This grassroots well is a slant producer targeting the Ivishak sands. The planned well is a three string, modified slimhole design using 10-3/4" surface casing, 7" intermediate casing, and 4-1/2" production liner. The surface casing will be set in the SV4. The intermediate casing will be set in the Shublik. The production interval will be completed with a cemented and perforated liner. The maximum anticipated surface pressure from the Ivishak with a full column of gas from TD to surface is 2,503 psi (assumes 7.35 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). The well will be drilled by Parker 272 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 3,500 psi. A detailed operations summary is included with the permit application. If there are any questions concerning information on 04-51, please do not hesitate to use the contact information below.

The 9-7/8" hole and 6-1/8" hole sections will be drilled with well control equipment consisting of 5,000 psi working pressure rams (2), blind/shear rams, and annular preventer capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 3,500 psi. BOP test frequency for 04-51 will be 14 -days with function test every 7 -days. Except in the event of a significant operational issue that may affect well integrity or pose safety concerns, an extension to the 14 -day BOP test period should not be requested. 9-7/8" Intermediate Interval Maximum anticipated BHP 3,065 psi in the OA at 6,550' TVDss 9.0 ppg EMW, 6,618' TVD Maximum surface pressure 2,403 psi in the OA 0.10psi/ft gas gradient to surface Kick tolerance 25 bbls with 11.7 ppg frac gradient.

To avoid the risk of plugging the flow line with large rocks and wood encountered while drilling surface hole, it is requested to drill without a flow paddle for the first portion of the surface hole. After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line (<1000 ft). This is a variance from 20 AAC 25.033. s- Procedures/Safeguards with paddle removed: • Fluid levels will be monitored in the pits for both gains and losses while drilling. Alarms will be set to indicate if gain or loss of more than 10 bbls has occurred. • The well will be monitored for flow when the pumps are off at each connection. • The planned 8.7 — 9.2 ppg fluid will provide over -balance to formation fluid. 04-51 PTD 8 2/9/2018 Drill and Complete Operations Summary Pre -Rig Operations 1.
