The well was P&A'd and operations suspended in September of 1998 after encountering poor reservoir quality at its planned Kuparuk target. Plans are to sidetrack the well to a new bottom hole location as a conventional producer targeting the J~uparuk reservoir. The sidetrack is currently scheduled for Doyon 14 beginning around January 12th,~after completion of the NK-19A drilling operations. Below find the planned scope of work for the sidetrack, and see the attached diagrams for addition details on current well condition and planned completion. Please call with any questions regarding the planned operations. Scope Pre-Ri.q Work: 1. Test the FMC 9-5/8" mandrel pack-off and tubing hanger seals to 5000 psi for 30 minutes. 2. Pressue test 9-5/8" casing to 3500 psi for 30 minutes. 3. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 4. If necessary, level the pad. Please provide total well preparation cost on the handover form. Ri.q 1. 2. 3. 4. Operations: ,/' MIRU Doyon 14.

Several alternative targets accessible from the existing 13-3/8" surface or 9-5/8" intermediate casings are currently being evaluated for sidetrack potential. To allow a detailed evaluation of the proposed sidetrack targets, operations on NK-11 are being suspended. Estimates for re-entering the well and sidetracking to an alternative development location are 6 to 12 months. If you have any questions or require any additional Information on this matter, please contact me at 564-5521. ', Sincerely, William S.

As explained, Well NK-11 was re-entered on July 20· of this year and operations were proceeding as per the general procedure submitted with the 'Application for Sundry Approval' (Approval # 398- 191). The whipstock was set at 18,652' MD and a window was milled in the 9-5/8" casing. The drilling assembly was then run In the hole and slid out the window, to kick-off the well and begin drilling ahead. Problems were encountered while trying to kick-off the well, when the 8-1/2" hole being drilled tracked the existing wellbore for approximately 150' prior to successfully kicking-off the well. The 8-1/2" hole was drilled to a total depth of 18,959' MD (291' below base of window), where the bit had to be pulled due to damage caused from tracking the existing casing. When attempting to slide out the window with the second drilling assembly, the bit hung-up on the top of the whipstock, damaging the whipstock. After several hours of attempting to get out the window, the declsion was made to plug back above the existing window and mill a second window. The 291' of 8-1/2" hole encountered no oil beating zones and was drilled entirely within the CoMIle Shale. After receiving verbal approval to plug back the open hole, a bridge plug was run and set at 18,565' MD in the 9-5/8" casing. Current plans are to run and set a second whipstock Immediately on top of the bridge plug and sidetrack out of the 9-5/8" casing at this new depth. If you have any questions or require any additional Information on this matter, please contact me at 564-5521. Sincerely, William S.

The portion of the hole which is at 21,284' is the Tuffs, which is noted for a breathing phenomenon where the mud is lost into the formation while pumping and then returned after the pumps have been turned off. The mud weight was raised to 11.0 ppg to aid in keeping the hole in check, but this cure the problem and only exacerbated the breathing problem. The well will now be plugged back and redrilled with a different directional plan in order to get past the Tuffs. ].

December 7, 1997: I witnessed the weekly test of the BOPE on Pool rig #7 which was drilling BPX well #NK-11 in the Niakuk Field. The BOP test was started at 0600 hours and lasted approximately three hours. All BOPE functioned properly and held its pressure test with the exception of the following, The isolation valve downstream of the manual choke leaked slightly and the balance stem packing on the HCR leaked. The rig appeared to be in fair shape and the crew performed well during the test. I left before the repairs to the failed valves were completed. The crew was working on these and I felt confident a proper repair and retest would be performed. The area surrounding the rig was clean although access to the rig was somewhat limited. SUMMARY: I witnessed the initial BOP test on Pool rig #7 drilling BPX well NK-11 in the Niakuk field. Test time 3 h_~, tw._o failures.
