In the planning phase of the well, we did have two coiled tubing reels specifically built to meet the extended length required to drill both laterals. However, due to equipment failure for the first reel & human error for the second reel we do not have the required equipment to start drilling AL2. We do plan to return to W -12 and drill the second lateral. This process to acquire two more reels of sufficient length from the manufacture will require time. I need guidance on how to leave W -12 (operational shutdown or otherwise). Many thanks.

Submit a 401's for each lateral with a full detail of the operational steps (pre and post lateral drilling operations) needed and you should be good to go.

However, the plug set at 15,050' and failed and allowed the cement to get past it and inside the 41/2" liner. To the best of my knowledge, the current top of cement inside the 4'/2" liner is 15,850' and with an unknown bottom of cement (could be all the way to PBTD or shallower). As Nordic 1 is planning to mill all of the cement inside the liner, drill two laterals, retrieve the whipstocks, and re perforate the area that was plugged with the failed squeeze cement jobs in 2007 (see schematics attached). Question: Do I need to submit an application for Sundry Approval? Or, would an application for PTD suffice?

ROP slowed to --3FPH. During milling we were able to stack weight on ther bit, pickups were clean at 24K each time and we were able to go right back to the same spot we left off and set down. Decision was made to chase a final Geovis sweep off bottom at 80% all the way to surface and look at the 3.70" OD Turbo mill. At surface with BHA and mill looks NEW with no wear on the face and minor scratches on the sides. While at surface the decision was made not to RBIH until a longer coil string was installed as we only had -8T left on the reel where we left off milling While freeze protecting the wellbore we had good infectivity so we opted to have ASRC test seperator attempt to flow the well while on gas lift before they rigged down the test unit.

Diverter, BOPE and mud fluid system schematics will be provided when determining rig (rig will be in the current fleet of north slope rigs and the schematics should therefore be on file with AOGCC). Maximum anticipated bottom hole pressure is 3933 psi at 8800'TVDss. Maximum anticipated surface pressure assuming gas in entire annulus (0.1ppg) is 3053 psi. Hazards · This well will penetrate ,-,600' of lower Kingak at 56° in the 8-1/2" section. Good drilling practices, including optimized flow rates of 410-430 gpm, slower trip and connection speeds, pumps at 40% when reaming connections, larger nozzle area for reduced sidewall erosion, all will Assure a trouble free interval. · There are 4 known faults in the reservoir interval ranging from a 20' through to a 90' throw. Lost circulation across the faults which will be controlled with productive zone LCM pills and/or weighted seawater for reduced fluid loss expenses. _. Low reservoir pressure and lost circulation due to Iow pore pressure within the reservoir interval. Disposal 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. W-12a Short Well Summary Pre-Rig Work: NOTE: If any problems are observed with the 95/8'' packoff during pre-rig operations, notify the Operations Drilling Engineer, Nabors 18E Company Representative and the wellhead manufacturer.

Diverter, BOPE and mud fluid system schematics will be provided when determining rig (rig will be in the current fleet of north slope rigs and the schematics should therefore be on file with AOGCC). Maximum anticipated bottom hole pressure is 3933 psi at 8800'TVDss. Maximum anticipated surface pressure assuming gas in entire annulus (0.1 ppg) is 3053 psi. Hazards · This well will penetrate ,-,600' of lower Kingak at 56° in the 8-1/2" section. Good drilling practices, including optimized flow rates of 410-430 gpm, slower trip and connection speeds, pumps at 40% when reaming connections, larger nozzle area for reduced sidewall erosion, all will Assure a trouble free interval. · There are 4 known faults in the reservoir interval ranging from a 20' through to a 90' throw. Lost circulation across the faults which will be controlled with productive zone LCM pills and/or weighted seawater for reduced fluid loss expenses. Low reservoir pressure and lost circulation due to Iow pore pressure within the reservoir interval. Disposal 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. W-12a Short Well Summary Pre-Rig Work: NOTE: If any problems are observed with the 95/8'' packoff during pre-rig operations, notify the Operations Drilling Engineer, Nabors 18E Company Representative and the wellhead manufacturer. Repairs will be made prior to initiation of rig work. 1. RU wireline and retrieve SSSV at 2278'.
