Isolation of the existing perforations with a cast iron bridge plug followed by a new coil tubing drilling sidetrack is proposed. The CTD side track will be a high angle step-out well to target Z1 A/1 B reserves in the Mid-Field graben south of DS 18. WELL HISTORY/CURRENT STATUS: C-18A was coil sidetracked in Jan 2000 with 1000' drilled in Zi B and 443' initially perforated. During the original completion, the tubing-conveyed perforation guns became stuck after firing and were never successfully fished out of the well. In April 2000 the well was kicked off with an N2 lift because the well lacks GLMs. The well produced full-time, following the initial rate decline until it reached MGOR in late 2000. In January 2001, 210' of Z1 B perforations were added in the heel of the well, resulting in ~1 month rate buzz before reaching MGOR and cycling. In December 2002, 30' of adperfs were shot uphole from the January 2001 adperfs; however, these adperfs resulted in no benefit. A third set of adperfs were added to this well in May 2005, which included re-perforating a portion of the Dec 2002 adperfs. There was an increase in oil production, but it did not sustain for long and the well went back to cycling with diminishing ontime. A July 2006 STP/MCNL did not clearly identify any adperf or GSO opportunities, although there was slight cooling (1 °F) at the base of the 13020-13050' perf interval. Because the well had very low ontime, an end-of-life CIBP was set for a gas shut-off at 13000' MD on 9/10/08, allowing only the top set of perfs to produce. The plug cut both oil and gas rates. The GOR remained on the same trend, and the well continued to cycling until it no longer healed and was shut-in for high GOR in April 2009. A SCMT log run on 6/6/04 indicated the top of cement behind the 2-7/8" liner was at ~12350' MD, which is below the TSGR allowing for a cut-and-pull of the liner for a big coil sidetrack. During CTD screening in March 2009, the well passed a MIT-IA to 3000 psi and a MIT-OA to 2000 psi. The PPPOT-T & IC passed on 6/5/09. A caliper log run 2/15/09 indicated the tubing is in fair condition with a maximum wall penetration of 39%, and the liner is in poor condition with a hole at ~11655' MD and an isolated pit with 77% penetration at 11637' MD. REASON FOR SIDETRACK: C-18A is not a competitive well, exhibits minimal recharge, and has low remaining value. Plan to isolate perforations with CIBP and primary cement job. ~ C~I~cu~. -~c~l ti~y ~~~ 4'"l~ ~~~~;CP ~eceMb~ ( ~~ ~~Cr` d h a~~ ~~~ _ G~ Q lvr~ r~~d~ ~t t /~rr~~ ~ 1` ~~l>~~C~`, ~n , ~ ~- q~e /Jp~''6 Cv,~~n t~ Q ~~f~+^' ~G f ~i'vf P ~ /~'IG lG~ /.S ~ ~ ~~e~a~/`c ~~a~~ct~`D~ ~"~'~k a~~cs~tif,~ ~e~if-,=Tj~ i ~OS~ ~rc~y `~"`~~~ ,,iPtl i`r~, r'A/~ ~yr o~ ~ y/ poc~ tt~ B.~CX~ 0 s c~~sr~~- d~ur,,^~ /e GG,~>-- ~/p~,~Pc~ S%G~'e 7~/qCi~C Tt.~iy~Tf ,.(~.f~•'~f ~s;P ~Q'~~/f ~rr) Q~~C*Gl r~~~~,~ ~/~4y c~On~c~g7`.

As the attached AOGCC Test Report indicates the test lasted 5 hours and there was 1 failure. One test on the choke manifold (4 downstream valves) failed to hold pressure. An individual leaking valve was not identified, instead the entire choke manifold was serviced and testing resumed with no further failures. In addition to servicing the choke manifold several problems were encountered with the test pump adding to the over all test time. The Rig was clean and all related equipment appeared to be in good condition. SUMMARY: I witnessed the initial BOPE test on Nordic Rig 1 drilling BPXs C-18A Well.

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. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Robert N. Christenson, P.E.

Phase 1' Set Whipstock, squeeze perfs: Planned for Jan. 5, 2000. · A Mechanical Integrity Test was successfully performed on 11/19/99. · The whipstock drift and PDS caliper were run on 12/14/00 Phase 2: Mill Window, Drill & Complete sidetrack: Planned for Jan. 12, 2000. Directional drilling coiled tubing equipment will be rigged up to mill the window then drill and complete the directional hole as per attached plan to planned TD of 14,846' MD (8,774' TVDss). Mud Program: · Phase 1' Seawater · Phase 2: Seawater and FIo-Pro (8.7 - 8.8 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: · 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 11,576' MD and cemented with approx. 25 bbls. cement to bring cement 200 ft above the window. The liner will be pressure tested to 2200 psi and 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. Directional · See attached directional plan · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · A Gamma Ray log will be run over all of the open hole section. · Open hole will be logged with Memory Induction log. Hazards No faults or lost circulation are expected. Res. pressure is normal. Reservoir Pressure Res. pressure is 3400 @ 8800ss. Max. surface pressure with gas (0.12 psi/fi) to surface is 2344 psi.
