Fullbore was unable to rig up on the well and perform a thaw due to the proximity of Parker 272's return tank.The rig did not move until 06/13/18 and Fullbore performed a thaw on 06/15/18. The well was POP'd on 06/16/18 and subsequently failed a warm TIFL on 06/17/18. Due to the delay caused by the rig operations,the 28 day Under Evaluation clock will be reset to allow for the remaining diagnostic work and repairs. Plan Forward: 1. Slickline: Change out GLVs 2.

During the 4-1/2" liner cementing we lost 73%of return after cement exit the shoe. Cement evaluation log indicate that there is only patchy cement in the sump of the well. We are currently planning following operations. - Perforate bottom perforation in 4-1/2" liner at 12455-12460' - Set cement retainer 12445' - Set liner top packer - Perforate top perforation in 4-1/2" liner at 10495-10500' - Sting-in to cement retainer, establish circulation and attempt to cement 4-1/2"x6-1/8" annulus - Perforate as per geologist If you have any questions, please let me know.

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.

While the flow paddle is removed from the flow line, PVT alarms will be used and the pit levels accurately monitored for any pit gain. Also, a visual check will be made during connections by looking down the riser to ensure the well is not flowing.

These mixing facilities can mix and deliver weighted fluid more efficiently than can be achieved at the drilling rig; however, on a case by case basis, such as when we are drilling at a more remote location,we may store sufficient materials on the rig. DS 07 is not considered a remote location, therefore the contingency plan for drilling into higher than expected pore pressures will be to weight up with fluids from a mixing facility.
