The pressure was discovered when DHD attempted to bleed the annulus and found the jewelry was frozen. Upon clearing the ice block the OA pressure was reported to be 1,160psi. N-10 has known OA repressurization from an external shallow gas source that normally stabilizes at"750psi. At this time the well is reclassified as Under Evaluation and is on the 28 day clock for diagnostics and repair. Plan Forward: 1. DHD—Collect OA fluid sample for lab analysis 2. DHD—Arctic pack dump OA to evacuate fluid 3. DHD—MIT-OA to 1,500psi, if fails freeze protect annulus with methanol 4. DHD—Outer annulus repressurization test(OART) 5.

The testing proceeded as scheduled and was performed in a safe and proficient manner by Nabors Drilling personnel with one failure. The lower kelly valve failed to hold pressure initially and was replaced while 1 was on location and passed the re-test. I witnessed a random inspection of the gas detection alarms on the rig floor and in the mud pits with no failures. Records kept on the rig indicated that all the gas detectors had been tested and calibrated earlier that day. The rig appeared clean and in good condition and the location was well organized. Summary: I witnessed an initial BOPE test and a random gas detector system test on Nabors rig 9-ES performing a re- drill operation on Phillips Petroleum's N-Pad well# l 0A. Total Test Time: 4 hrs.

The permit to redrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

Maximum anticipated BHP: 3305 psi @ 8571'TVDss - Zone 4 · Maximum surface pressure: 2448 psi @ surface (based on BHP and a full column of gas from TD @ 0.10 psi/ft) · Planned BOP test pressure: · Planned completion fluid: 3500 psi 8.5 ppg Seawater/6.8 ppg Diesel N-10A Permit to Drill Drilling Hazards/Contingencies: HYDROGEN SULFIDE - H2S · N Pad is designated as an H2S drill site and Standard Operating Procedures for H2S precautions should be followed at all times. The highest level of H2S ever measured on N Pad has been 277 ppm from N-23. The latest H2S information on N-10, shows levels as high as 68 ppm. DRILLING CLOSE APPROACH' · All wells pass close approach guidelines. INTERMEDIATE SECTION: · Gas cut mud has been observed in the Ugnu (KOP @ 4800' TVDss) and West Sak (5067' TVDss) sands. This will be controlled with appropriate mud weights. A minimum of 9.4 ppg is recommended. · The N-10A well path will drill full sections of both the HRZ and Kingak shale. · Tight hole conditions and stuck pipe have been encountered in the Kingak shale interval. Increased mud weights and the addition of shale stabilizers may be required. · Lost circulation in the intermediate section has not been a problem at N Pad. · The kick tolerance for the 8-1/2" open hole section would be 157 bbls assuming an influx from the Sag River interval at -9106' MD. This is a worst case scenario based on a 7.8 ppg pore pressure gradient, a fracture gradient of 12.0 ppg at the 9-5/8" window, and 10.1 ppg mud in the hole. PRODUCTION SECTION: · The N Pad area is highly faulted and these faults have a history of being conductive, resulting in numerous lost circulation incidents. As planned, five faults will be crossed while drilling the reservoir section of N-10A. Of the five faults, fault 3 is the highest risk due to the anticipated stress orientation. The well plan has been optimized to cross this fault at a point of clean offset, but due to the structure, fault 3 is planned to be crossed Iow in the reservoir section at a point of sand-on-sand (poor seal) juxtaposition. The fourth and fifth faults crossed within the reservoir have less risk than fault 3, however still represent a 'moderate to high' risk of losses because they cross close to fault tip-out zones. To be prepared for any potential lost circulation, a copy of the 'Recommended Lost Circulation Procedures' and the 'Lost Circulation Decision Tree' will be sent to the rig prior to drilling out in the 6-1/8" production interval. · Differential sticking will be a problem if lost circulation is occurring or if the drill string is left stationary for an extended period or time. · The kick tolerance for the 7" shoe would be an infinite influx (annular volume) assuming an influx at section TD of 10,870'. This is a worst case scenario based on a 7.8 ppg pore pressure, a minimum fracture gradient of 9.5 ppg at the 7" casing shoe, and 8.3 ppg mud in the hole. Disposal: · No annular injection in this well. · Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. · Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I wastes to Pad 3 for disposal. N-10A Permit to Drill SUMMARY SIDETRACK PROCEDURES Pre-Riq Work: * Notify the field AOGCC representative with intent to plug and abandon * 1. RIH with CTU and perform a cement P&A using 15.8 ppg class 'G' cement with adequate cement volume to fill the 7" liner from PBTD at 10,135' MD and extend up into the tubing tail N100', plus squeeze 5 bbls to the perforations. Estimated minimum cement volume needed is 28.6 barrels. Use aggregate as required to aid in plugging the perfs. NOTE: The AOGCC has requested on prior sidetracks exiting above the reservoir, that the top of cement be brought up into the tubing tail ~100', therefore the minimum top of cement should be 9,422'. Top of cement may extend further up into the tubing as long as it does not interfere with the upcoming tubing cutting operations. 2. Rig up slickline, tag and document top of cement and drift tubing for upcoming tubing cut. 3. Liquid pack the 9-5/8" x 4-1/2" annulus to surface. Test the integrity of the cement plug and 9-5/8" casing by simultaneously pressure testing both the tubing and 9-5/8" annulus to 3000 psi for 30 minutes. Increase tubing pressure prior to the 9-5/8" annulus to avoid possibility of tubing collapse. 4. RU E-line. Cut the 4 ~" 13Cr-80 tubing at approximately 8940' MD using a chemical cutter. This cut will not be fished, however avoid cutting a tubing collar. Displace the well to clean seawater by circulating down tubing through the tubing cut. Continue to circulate until clean seawater returns to surface. Freeze protect top 2200' MD with diesel. 5. Test the FMC 9-5/8" mandrel packoff and tubing hanger seals to 5000 psi for 30 minutes. 6. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 7. Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Ri.q Operations: 1. MIRU Nabors 9ES. 2. Circulate out freeze protection and displace well to seawater. Set TWC. 3. Nipple down tree. Nipple up and test BOPE. 4. Pull and lay down 4-1/2" tubing from E-line cut and above. 5. RU E-line and make GR/JB run to top of tubing cut. Set BP on E-line at -5223' MD (set as needed to avoid cutting casing collar). 6. RIH with 9-5/8" Baker bottom-trip anchor whipstock assembly. Orient whipstock as desired and set on BP. Mill window in 9-5/8" casing at -5200' MD. POOH. 7. Kick-off and drill the 8-1/2" intermediate section to Top Sag @ _+9106' MD (8533' TVD). 8. Run and cement a 7", 26# intermediate drilling liner, cemented -1000' above the 7" casing shoe. 9. Make up and RIH with 6-1/8" directional assembly to the landing collar. 10. Test the 9-5/8" casing and 7" liner from the landing collar to surface to 3000 psi for 30 minutes. 11. Drill the 6-1/8" production section as per directional plan to an estimated TD of 10,870' MD (8730' TVD). 12. Run and cement a 4 Y2", 12.6# solid production liner throughout the 6-1/8" wellbore. Displace well to clean seawater above liner top. POOH. N-10A Permit to Drill 13. Test the 4-1/2", 7", and 9-5/8" casing from the 4-1/2" landing collar to surface to 3000 psi for 30 minutes. 14. Pick up perf guns on 2-3/8" x 4-1/2" DP and RIH to perforate -400' of selective intervals. Perforate well with -200 psi underbalance to the reservoir. POOH LD DP. 15. Run 4-1/2", 12.6# 13Cr-80 New Vam completion tying into the 4-1/2" liner top. 16. Set packer and test the tubing to 3500 psi and annulus to 3000 psi for 30 minutes. 17. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. 18. Freeze protect the well to -2200' and secure the well. 19. Rig down and move off. Post-Riq Work: 1. MIRU slickline. Pull the ball and rod / RHC plug from 'X' nipple below the new production packer. Install gas lift valves.
