Verify hole is staying full and establish loss rate as necessary. Continue to continuously fill across the top. 24. MU landing joint or spear, BOLDS and pull hanger to the floor. PU weights are expected to be ~95K. a. Pull 4 1/2” tubing to floor, circulate bottoms up. Lay down 4-1/2” tubing. Number all joints b.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

This sidetrack well is a horizontal producer targeting Ivishak Z4 and Z2. The planned well is a sidetrack design using a 7" intermediate liner and 4-1/2" production liner. • The maximum anticipated surface pressure from the Ivishak with a full column of gas from TD to surface is 2,520-psi (assumes 7.28 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 09-27A, please do not hesitate to use the contact information below.

Sub-Surface Pressure Management: Ivishak Interval: 03-33C and 09-31 D are MIST injectors that are currently shut in but expected to be on injection at time of drilling. 03-33C's current and future perforations(within the next 2 years)will be more than 4000'away. 09-31 D is not currently perforated, and future perforations will be over 4000' away. Due to the 4000' spacing, 03-33C and 09-31D will not be shut in during drilling operations. Anti-Collision: All wells pass BP's anti-collision criteria, however 09-36C has been minor risked to mitigate HSE fisk ✓ and will be shut in while drilling the production interval. See attached A/C summary for more details. Offset well ownership information All offset wells identified within 200 ft of the proposed wellbore are operated by BP.

As part of the standard directional package,we also sent an additional anticollision report with a 500' MD extension. I see that in this reference design "09-27A wp07 plus 500' MD",well 09-07 is shown to fail major risk. However,there are no additional incremental reserves past the current TD, and there would be no advantage to drill the additional 500' MD, so it is not an option for this well plan. Please let me know if you need anything else on my end.
