Troubleshooting a leak on test #2 lead to pulling the test plug and redressing it before reinstalling it to continue testing. Also service HCR Kill and CMV #12. Upper IBOP and Lower IBOP failed during testing and were to be replaced. After finishing the test for the LPR, the rams were opened and the test plug and test joint came up out of the wellhead approximately six foot and contacted the top-drive. The well had been producing gas that pressured up underneath the test plug. After checking the pressure on the IA, the top-drive was raised and the tugger was installed onto the test joint to pull it out of the BOPs. Once the tugger started to pull the test joint the test joint and test plug were blown out of the BOPs and landed on the rig floor. The well was secured and an investigation into the incident was started. Testing was started again and I stopped testing again as gas was still present coming from the well. It was decided to install the tubing hanger back into the wellhead and not use the test plug to continue testing. Once the well was on a vacuum and the phase 3 status, that had ceased all work on the island, was lifted we went back to testing.

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.
