The 18-13AL1 original scope was to exit the existing liner at 11250' MD, ctose to horizontal, tum and drill a horizontal lateral to the north. The proposed completion strategy was to complete with a slotted liner with an openhole junction at the window, and retrieve the whipstock to allow future re-entry into the parent wellbore In the process of running the retrievable whipstock, it became stuck in the wetlbore and we have been unable to pull it out of the hole. We were successful in pushing it downhole to 9235, but have decided the best course of action from here would be to change the scope of this sidetrack. We are currently developing a plan to set a whipstock at 9200 8, MD, mill a window and directionally drill to the target Zone 1 horizon and drill a new horizontal lateral to a MD of 12700' MD. The new BHL witl be located roughly halfway between the 18-13A and the proposed 18-13 AL1 permitted SHL(greater than 500 feet away). Because of the change in KOP, the current. proposed completion will be a cemented and perforated liner. As such, the parent 18-13 A wellbore will be isolated by the cement and the new wellbore will be named 18-13B. We request verbal permission to pursue this new proposed scope and will fotlow with a formal revised permit to drill for the 18-138 as soon as we can complete the plans. Lamar L.

The permit is for a new wellbore segment of existing well 18-13A, Permit No 207-134, API 50-029-21756-60-00. Production should continue to be reported as a function of the original API number stated above. 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 Commission 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 Commission 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 a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). inc rely Dan T.
