As the attached AOGCC BOPE Test Report indicates, the test lasted 2.5 hours and there were no failures. The lower pipe rams were not tested at this time due to the length of the cross-overs required to engage the tubing hanger. The above mentioned rams were tested by the rig crew when the production tubing had been laid down. The testing went very well with the test procedure being practiced by the Nabors crew allowing the testing to be completed in a minimum number of steps. The rig was very clean and all equipment appeared to be in excellent condition. The location was clean and all extra equipment was properly stored. Summ~ry: I witnessed the initial BOPE test on Nabors Rig 9ES drilling BPXs S- 24A Well.

The highest level of H2S recently measured on S Pad has been 60 ppi from S-37 in December of 98. DRILLING CLOSE APPROACH: · All wells pass close approach guidelines. INTERMEDIATE SECTION: · Gas cut mud has been observed in the Ugnu (4300' TVDss), West Sak (4990' TVDss), and Kuparuk (6600' TVDss) sands. This will be controlled with appropriate mud weights. · The S-24Ai 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. · The kick tolerance for the 9-7/8" open hole section would be 19 bbls assuming an influx from the Kuparuk interval at -,,7700' MD. This is a worst case scenario based on an 10.0 ppg pore pressure gradient, a fracture gradient of 12.0 ppg at the surface casing shoe, and 10.4 ppg mud in the hole. PRODUCTION SECTION: · Differential sticking will be a problem if loss 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 13,040'. This is a worst case scenario based on a 7.9 ppg pore pressure, a minimum fracture gradient of 10.0 ppg at the 7" casing shoe, and 8.4 ppg mud in the hole. S-24Ai Permit to Drill , Disposal: No annular injection in this well. 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, except any metal cuttings which will be sent to the North Slope Borough. SUMMARY SIDETRACK PROCEDURES Pre-Rig Work: The foflowing pre-rig work has already been completed (under approved Sundry #398-313). The work was completed in early December of 1998, in preparation for this sidetrack, which was originally planed for a mid December spud. 1. CTU performed a cement P&A across the existing perorations using 40 bbls of 15.8 ppg class 'G' cement, of which 10 bbls contained 20 ppb aggregate. Cement was laid in across the perorations and 12 bbls were squeezed behind pipe, using the hesitation method. (11-29-98) 2. Slickline tagged top of cement at 9016' MD and pressure tested the cement to 3000 psi for 30 minutes, with a 150 psi loss. (11-30-98) 3. E-line cut the 4 1/2" L-80 tubing at 4512' MD (22' down into a 40' joint). (11-30-98) 4. The well was displaced to clean seawater through the tubing cut and diesel was U-tubed in to freeze protect to ~2000' MD. (12-1-98) 5. The 9-5/8" casing was tested against the cement plug to 3000 psi for 30 minutes, loosing 50 psi over the 30 minute period. (12-2-98) 6. The McEvoy 9-5/8" mandrel packoff was tested to 5000 psi and bled down to 3500 psi in 30 minutes. Nothing further was done, and plans were made to change out the pack-off as part of the sidetrack. The tubing hanger seals were successfully tested to 5000 psi for 15 minutes. (12-2-98) The foflowing pre-rig work will need to be completed prior to rig arrival 1. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 2. Remove the well house and flowlines. If necessary, level the pad.

Diverter, BOPE and drilling fluid system schematics on file with the AOGCC. · Maximum anticipated BHP: 3200 psi @ 8750' TVDss - Zone 4 · Maximum surface pressure: 2325 psi @ surface (based on BHP and a full column of gas from TD @ 0.10 psi/E) · Planned completion fluid: 8.5 ppg Seawater / 6.8 ppg Diesel Drilling Hazards/Contingencies DRILLING CLOSE APPROACH: · None INTERMEDIATE SECTION: · The Kingak shale is considered mechanically unstable over 50° inclination. The 6660' intermediate section will be drilled at inclinations up to 42° with mud asphalt products added for reduced shale reactivity. · Gas cut mud has been observed in the Ugnu(3800' TVDss) and Kuparuk(6500' TVDss) which will be controlled with appropriate mud weights. In addition, tight hole conditions have been encountered in the Kingak shales at 7400' TVDss. Mud weights as high as 11.0 ppg and the addition of shale stabilizers may be required. · The kick tolerance for the 8.5" open hole section would be 37 bbls assuming an influx at the 10,460' TD. This is a worst case scenario based on a 9.0 ppg pore pressure gradient and a fracture gradient of 11.0 ppg with a 11.0 ppg mud in the hole. S-24Ai Permit to Drill PRODUCTION SECTION: · Stuck pipe has not been recorded in the production interval but differential sticking will be a problem if loss circulation is occurring. · The kick tolerance for the 7" shoe would be an infinite influx(annular volume) assuming an influx at the 13,858' TD. This is a worst case scenario based on a 7.2 ppg pore pressure and a minimum fracture gradient of 10.0 ppg with a 8.5 ppg mud in the hole. Disposal No annular injection in this well. 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, except any metal cuttings which will be sent to the North Slope Borough. SUMMARY SIDETRACK PROCEDURES Pre-Riq Work: , Perform a cement P&A of 15.8 ppg class 'G' cement with adequate cement volume to cover the 7" liner from PBTD at 10,385' to a minimum of 100' above the top perforation at 9834' plus squeeze 5 bbls to the perforations. Estimated cement volume needed is 30 barrels. A full bore P&A is recommended but is at the discretion of the Wells Group. There are no GLM's in the completion string. Note: Top of cement must be at a minimum of 9734' for AOGCC compliance. Top of cement may extend into the tubing as long as it does not interfere with the tubing cutting operations. 2. Rig up slickline, tag and document top of cement. 3. Cut the 4 1/2" L-80 tubing in the middle of a full joint of tubing at 4500'. This cut will not be fished and is at the discretion of the Wells Group as to chemical or jet cut. 4. Test the McEvoy 9-5/8" mandrel packoff and tubing hanger seals to 5000 psi for 30 minutes. 5. Test the casing against the cement plug to 3000 psi for 30 minutes. Freeze protect top 2200' MD with diesel. Ensure the cut is successful and communication exists between casing/tubing to avoid tubing collapse. 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 7ES 2. Circulate out freeze protection. Set TWC. 3. Nipple down tree. Nipple up and test BOPE. 4.
