The pressures were confirmed to be TBG/IA/OA SSV/2100/0 psi. A cold TIFL subsequently failed on September 10, 2015 indicating a lack of potential downhole barriers.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

You state that none of the well records you reviewed from this pad, including the recently drilled P-26 well (December 1996), reveal any operational difficulties relating to shallow gas prior to placement of surface casing. We concur that the lack of shallow gas in the PBU P-26 well and other wells drilled from this pad supports granting a waiver of a diverter system for PBU P-25 well. Your request for a waiver is approved. Although we are approving a waiver of the diverter system for this well, the operator must be prepared to accommodate any hazards that may develop over time. Each well should 'be carefully monitored to detect developing hazards, and subsequent well operations conducted accordingly. Chairman ~ .

Johnson Date: February 19, 1997 Subject: P-25 new well, Request for dispen;ation for 20 ACC 25.035 (7)(b) Shared Services Drilling requests your consideration of a waiver of the diverter system identified in 20 ACC 25,035 (7)(b) ~Secondary Well Control: Blowout Prevent/on Equipment (BOPE) Requirements" based upon historical drilling experience on PBU P Pad, This waiver is requested for the upcoming new well P-25. The P-25 Permit to Drill (permit #97-26)was approved on 2/13/97. Of the wells reviewed that were drilled at P Pad, none experienced any difficulty with shallow gas in the interval prior to placement of surface casing. In addition, within the last 2 months, new well P-26 was drilled through shallow intervals without any indication of shallow gas. A clear path for diverter line installation on the P-25 locat/on is very difficult due to the production flowlines which are placed directly in the path of the diverter linc. In light of historical evidence indicating minimal risk due to shallow gas at this location, we conclude that the P-25 well on the same pad can be safely drilled without the installation of the diverter system.

Drilling Hazards/Contingencies · Pore pressure may be as high as 9.2 ppg EMW in the Ugnu (-4545' TVDSS) due to water disposal. Will ensure appropriate mud weight for overbalance. · Gas cut mud has been observed at 7365' TVD SS (Miluveach) and will be controlled with appropriate mud weights. In addition, tight hole conditions have been encountered in the Kingak shales at -7500 TVDSS. Mud weights as high as 10.4 ppg and the addition of shales stabilizers may be required. · P Pad is not an H2S pad. The highest H2S level on the pad is from P-4 at 69 ppm in 12/95. · Losses have been encountered drilling the Sag River, Shublik and Sadlerochit formations on other P-Pad wells. Pump LCM as necessary to control losses. Disposal · Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. · Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. In addition, haul all cuttings from drilling operations to CC- 2A for disposal, excep('any metal cuttings which will be sent to the North Slope Borough.
