H-04 and H-08.The losses are not bad enough to cease drilling but we are planning on pumping LCM material to cut down the rate of losses. If there is any escalation to the losses or water in other conductors, I will notify you as the events happen.

Thanx, Victoria From: Rosenbaum, Jesse E [mailto:Jesse.Rosenbaum©bp.com] Sent: Tuesday, August 04, 2015 5:35 PM To: Loepp, Victoria T(DOA) Cc: Endacott, Mary S; Lastufka, Joseph N; AK, D&C Rotary Operation Superintendent Subject: H-40 Grassroots PTD#215056 - 13-3/8" Contingency String Hello Victoria, H-40 is planning on spudding tomorrow. H-40 is planned to drill a 12-1/4" OH surface interval and cased with 9-5/8",40#, L-80, BTC casing. One of the main risks for H-40 is the possibility shallow losses in the surface interval. If Parker 273 encounters losses that cannot be stemmed by lost circulation material (as seen in various parts of the field),the contingency is to ream the hole to 16"then run 13-3/8",68#, L-80 BTC casing and cement it to surface.The 13-3/8" (if run), is planned to be hung off in the conductor in the butt-weld sub. The butt-weld sub is a landing profile that is welded to the inside of the conductor 2-3 ft below the landing ring. Since this is a contingency, we did not include it in the original permit however, if encounter losses at surface where the rig cannot drill ahead, I would notify you and submit the plan of the 13-3/8" curtain string. This would essentially act as a conductor extension and enable the rig to stem losses and drill ahead to planned surface TD at 3166' MD with a 12-1/4" drilling assembly per the original permit to drill. If you are in agreement with the contingency plan,we will execute accordingly only if severe shallow losses prevent drilling ahead. As always,feel free to contact me with any questions.

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.
