W- 21 is currently shut-in and is incapable of producing due to a packer leak. The well is planned to be sidetracked to a new bottom hole location as a conventional horizontal producer targeting Zone 4 of the Ivishak formation. · Notify the field AOGCC representative with intent to plug and abandon. * Pre-Riq Work Outline W-21: 1. MIRU Slickline. Drift 3 W' tubing to packer depth @-9783' MD (58 deg inc). Refer to W-21A schematic. Note minimum restriction of 2.75". 2. Plug and abandon w! 13.8 ppg Class G cement. Pump cement volume to abandon perforation interval from top fish (2-7/8" cut tubing) at 10329' to the WLEG at 9862'. This will effectively fill 467' of the 5-1/2" casing annulus ~ 5~ ~"/(. ~ ~~ ~'~~'~ Note: Tubing will be subsequently jet cut at approximately 9768'. Note: The estimated pore pressure of the open perforations is 7.7 pg at 8800' TVD (3520 psi). 3. MIRU S/L. Drift/Tag TOC. Document top of cement per AOGCC requirements. An AOGCC representative may wish to witness the tag. 4. If TOC is found higher than planned jet cut, MIRU coil unit and clean up cement stringers. Pressure test plug and record on chart. 5. Test the McEvoy 9 5/8" paCk-off to 5000 psi and service lock down studs by backing out and re-torqueing one at a time. Test the tubing hanger pack-off to 5000 psi and service each LDS. Note: Do not test the 9 5/8" annulus. The production packer failed to test after the last rig workover in November 1990 and the well was subsequently shut in. Prior to running the completion the 9-5/8" annulus was tested to 3000 psi to a depth of 9897'. 6. MIRU E/L unit. RIH with jet cutter and sever 3 ~" tubing at -9768' MD. This is in the middle of the pup joint below GLM #1 handling pup. (See completion tally) Allow tubing/annulus to equalize. Circulate the well with seawater and freeze protect the IA and tubing. Note: The drilling rig will set a 7" CIBP and whipstock after removing the 3 ~" tubing above the cut. 7. Set a BPV in the tubing hanger. Secure well with 0 psi on tubing and annulus. 8. Remove the well hous flow lines. Level the pad and dig o~{~t~e cellar. Please provide total well preparation cost on the hand over form to the drilling rig representative. Ri.q Side-track Operati utline W-21A: . . . . . MIRU Nabors 7ES. Circulate out freeze protection and displace well to seawater. Ensure BPV is set. Nipple down tree. Nipple up and test BOPE. Pull and lay down 3 1/2" production tubing, SSSV nipple, control line and GLM's from E-line cut. Check for NORM and record on Morning Report. Replace 9-5/8" casing head pack off as required. PU 4" DP & collars. TIH w/8-1/2" watermelon mill assembly (without starter mill) and tag cut tubing stub at 9768'. Note the whipstock depth at +/-9750'MD is at 55 degrees inclination at an azimuth of 35 degrees and a TVDss of 8525'. The TJB Kingak Shale formation is opposite the proposed side-track depth. Set 9-5/8" CIBP on E-line at whipstock depth. (Note: 9-5/8" casing is 47 Ib/ft) Set per Baker recommended depth, for this size whipstock, to avoid milling casing collar). Pressure test 9 5/8" casing to 3500 psi. TIH with 9-5/8" Baker bottom-trip anchor whip-stock/mill assembly. Orient whip-stock to - 85 deg right of high side with MWD as required and set.

Drill -5000' of 6-1/8" hole to TD at 15,111' MD. Run MWD/GR/RES/NEU real time LWD. Spot liner running pill in open hole and POOH. 10. Run 4 ~", 12.6# 13Cr solid production liner, w/150' of lap, to TD. Pump cement, drop wiper plug and displace with "perf pill" followed by mud. Hydraulic set liner hanger and top liner packer, unsting and circulate cement from liner top. 11. Test the 4-1/2", 7", and 9-5/8" casing from the landing collar to surface to 3500 psi for 30 minutes. Displace well to clean seawater above liner top. POOH laying down excess drillpipe. 12.

Chatterton, Chairman Oil and Gas Conservation Commission State of Alaska 3001 Porcupine Drive BP Exploration (Alaska) Inc. 900 East Benson Boulevard Anchorage, AK. 99501 S~-~L--~ Dear Mr. Chatterton: j~r~r~~, BP Exploration is requesting a~inistrative approval, a~/ Conservation Order No. 213, Rule 2, to waive productivity profile requirements for new Prudhoe Bay Unit well W-21. The waiver is requested because the well is a high angle completion of 82". The completion intervals are as follows: RO. Box 196612 Anchorage. Alaska 99~,~ (907) 561-5111 ,~9 1 coJt,l~--~2.E.~r v 10,850-10,950'MD (100') 10,975-11,140'HD (165') 8,910-8,925'ss (15' TVD) 8,929-8,954'ss (25' TVD) If production characteristics would warrant evaluation for remedial work, production logs would be obtained at that time. Because all production logs would be coiled tubing conveyed, there is an increased risk associated in obtaining them. If you require further information, please contact S. L. Bryant (907) 564-4203.
