I made a follow-up inspection of infractions Doug Amos found with no fire protection on control lines. Nabors installed all new control lines with fire resistant rubber covered steel control lines. I inspected the rest of the rig and found it in compliance. I filled out an AOGCC BOPE Walk-Thru Inspection Report attached. In summary: Nabors rig 28E on BPX PBU DS 4-36 seems to be in complete compliance. The inspections were satisfactorily performed.

The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sx of cement followed by Arctic Pack. b. Minimum distances of wells within 200 ft. of the proposed well are' o DS 4-33 '59' @ Surface O DS 4-16' 119' @ 700' MD/700' TVD O DS4-17: 176' @ 700' MD/ 700' TVD c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.033. d. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/ft). e. Based on previous logs on DS 4, no potential productive zones are anticipated above 3500' TVD. f. No potential hazardous levels of H2S are anticipated in this well.
