This horizontal Ivishak Zone 4 producer has been shut-in since August 2003 due to multiple liner 1 tubing leaks and poor oil production. The wellbore is providing no production or value to the field as it currently sits. ,/ The original N-11 was drilled to a downthrown block, and P & A'd. N-11A was drilled in 1985, and POP in 1986. 3300 bbls of fluid were lost to a fault in Zone 4. Production from N-11 A was dominated by the fault, quickly stabilizing at 8 MBFPD, 90% we, and increasing GOR. Please note that N-11A was never fracced, so GFR is a strong indicator of fault dominance in this case. An attempt to optimize the completion with a sand plug in 1991 failed to materially impact production. N-11B was drilled as a U-shaped coil sidetrack in 1999. Severe problems were encountered with lost circulation in the heel. A loss increase was also noted at a predicted fault in the "belly" of the well. The well was cemented with partial returns and a liner top packer was set after the liner failed a pressure test. However, N-11B did penetrate a NLOe of 108' TVD. Initial production was at solution GOR and less than 10% watercut, indicating initial isolation from fault related production. However, a trend of simultaneously increasing GFR, we and GOR was soon established. Standalone tests in early 2002 were reminiscent of N-11a with nearly 90% we, and a GFR in excess of 7 MBD. In May 2003, a caliper survey indicated multiple holes in the tubing, and two parts in the 2 7/8" liner, one at the window, and the other at one of the liner leaks observed in the earlier PL T. The mechanism for the parting appears to be corrosion / erosion, since wall thinning can also be observed across from a number of holes as well. N-11 B had to be safed out due to T x IA communication, and high SIWHP. Due to leaks in the packer and " tailpipe, an IBP in the tubing tail was unsuccessful in safeing the well out. The well was finally made safe by setting a elBP in the liner, and pumping sand slurry down the backside of the liner. A plug is also sitting on top of the eIBP. The N-11e low angle well bore is designed to exploit the thick Zone 4B NLOe in a Western fault block on .... N-pad. The wellbore path is oriented in an East to West direction. The intermediate section will be drilled / to the top of the Sag River where a 7" liner will be set and cemented. The production section will drop angle and TD 200' MD below the PWOC. A fully cemented solid liner will be run. The N-11 e sidetrack is currently scheduled for Nabors 7ES beginning around 08/10104, after completing the N-01A sidetrack. The pre-rig work for this sidetrack will be priority scheduled immediately after the Application for Sundry is approved. N-11 C Application for Sundry SCODe Pre-Ria ODerations: a.

The volume of annulus below the production packer between the 9- 5/8" casing and 4-1/2" tubing is -4.0 bbls. This annulus is accessible due to existing tubing punches at 9547-9557'.

The permit to rcdrill 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. In accordance with 20 AAC 25. 005(f), all records, data and logs acquired for the pilot hole must be clearly differentiated in both name (N-ll BPH) and API number (50-029-21375-70) from records, data and logs acquired for well N -11 B. Blowout prevention equipment (BOPE) must be tested in accordance ,Ùth 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allo,,- a representative of the Commission to witness a test of BOPE installed prior to drilling ne,," hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Robert N. Christenson. P. E.

The sidetrack, N-11 b, will target Zone 4A and 4B reserves. This sidetrack will be conducted in two phases. Phase 1: Set Whipstock: Planned for Nov. 5, 1999. · A Tubing Integrity Test will be performed. · The whipstock drift and Kinley caliper will be run. · A mechanical whipstock will be set on e-line at approx. 9900' MD. Phase 2: Cement perfs, mill window and drill pilot hol~and lateral: Planned for Nov. 10, 1999. ~--- Directional drilling coiled tubing equipment will be rigged up and utilized to cement perforations, mill the window and drill the sidetrack to a planned TD of 11,212' MD (8,637' TVDss). Mud Program: · Phase 2: Seawater and Flo-Pro (8.6 - 8.7 ppg) Disposal: - No annular injection on this well. - All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. - All Class I wastes will go to Pad 3 for disposal. Casing Program: - 27/811,6.16#, L-80, ST-L liner will be run from TD to approx. 9,585' MD and cemented with approx. 17 bbls. cement to bring cement 200 ft above the window. The well will then be perforated with coiled tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi.
