The rig team spooled the split section of coil onto the reel (with the weight of the downhole coil section supported by the injector) and continued POOH, keeping the hole full via the kill line. The well control levels of protection during this incident were keeping the hole full with KWF, dual checks in the BHA, and blind/shears in the BOPE. The coil that failed was only at 34% of expected life and had not given any indications of problems prior to this incident. The coil manufacturer is doing a full failure analysis to determine failure mechanism. John From: Maunder, Thomas E (DOA) [mailto:tom.maunder@alaska.gov] Sent: Wednesday, October 01, 2008 11:26 AM To: Archey, Pat; McMullen, John C Cc: Regg, James B (DOA) Subject: V-115L2 (208-110) Pat and John, I have reviewed the completion report for V-115L1 and V-115L2. It is reported that late on August 11 that the coil parted while pulling out of the hole. We would appreciate some further information on this incident and the resolution. It does not appear that there were any injuries and that any spill was small. We are interested in the well control aspects of this failure. It appears that the string remnant did not fall down the hole and that pressure integrity was maintained. I look forward to your reply.

The V-115 well was drilled in 2004 and has been shut-in for most of its life due to low productivity related to poor reservoir quality. The coil-tubing laterals are proposed to establish increased productivity from improved reservoir in Kuparuk to the southeast (L1) and north (L2) from the parent well. The reservoir targets for V-115 L1 are the Kuparuk C4 and C1 sands, as encountered in the toe of Z-112 approximately 2200 ft. to the south. Total planned measured depth for the V-115 L1 lateral is 1,600 feet. Initial production in L1 will be primary, with future consideration for injection support. The reservoir targets for V-115 L2 are the Kuparuk C4, C2 and C1 sands. V-115 improved reservoir quality to the north and east of the parent well is seen in offset injector V-100 and is also suggested from seismic attributes possibly related to distribution of siderite cement. Total planned measured depth for the V-115 L2 lateral is 2,770 feet. Pre-Rig Work: 1. O PT aster & Swab valve to 3500 psi. Drawdown test MV and SV to 0 psi 2. O PPPO -T & IC 3. S Obtain HP 4.

Disposal: • 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. Hole size: 3" Casing Program: • 2 3/8", 4.7# , L-80, STL slotted liner • V-115L1 - 9725'MD -1.1,300' MD • V-115L2 - 8205'MD - 10,950' MD Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Max. planned hole angle is 92 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 9,800' (Northeast) Anticollision Summary V-115L1 • Z-22B - 993' ctr-ctr, Status: Producing • Z-30A - 1202' ctr-ctr, Status: Producing June 5, 2008 V-115L7 & V-115L2- Coiled Tubing Drilling V-115L2 • V-100 -1150' ctr-ctr, Status: Injector: 1150 psi surface pressure • Z-30A -1202' ctr-ctr, Status: Producing Logging • MWD directional, Gamma Ray, and Resistivity will be run over all of the open hole section. Hazards • The maximum recorded H2S level on V pad is 300 ppm on V-117(04-03-2007). V Pad is an H2S pad; H2S procedures will be followed. • Lost circulation risk is low. Only one small fault crossing is expected and it was crossed in the parent well with no issues. Reservoir Pressure • Res. press. is estimated to be 2,928 psi at 6,600'ss (8.5 ppg EMW). Maximum surface pressure with gas (0.10 psi/ft) to surface is 2,268 psi.

(7) Data presented here is final and has been depth adjusted to a the MWD data from well v-115L2 above the Kick off Point of 8174 ft MD per Bob Dawson with BP Exploration (Alaska), Inc. (8), The sidetrack was drilled from v-115 through a milled window in a 4 1/2 inch liner. Top of window 8174 ft.MD (6617.3 ft.TVD55) Bottom of window 8180 ft.MD (6619.4 ft.TVDSS) (9) Tied to v-115 at 8165 feet MD (6614.4 feet TvDSS). (10) The interval from 8619 feet to 8651 feet MD (6630.9 feet to 6630.3 feet TvDSS) was not lodged due to sensor to bit offset at well TD.

(2) All depths are Bit Depths unless otherwise noted. (3) All True vertical Depths (TVD55) are Subsea corrected. (4) All Formation Evaluation data is realtime data. Page 1 ~~ ~l d l ~/~lC U tapescan.txt <5) Baker Hughes INTEQ utilized coilTrak downhole tools and the Advantage surface system to log this well.. (6) Tools ran in the string included casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance sub (Inner and outer Downhole Pressure, vibration and Downhole weight on Bit), a Directional and Gamma sub, and a Hydraulic orienting sub with a Near Bit Inclination sensor. (7) Data presented here is final and has been depth adjusted to a PDc (Primary Depth Control) log provided by schlumberger open Hole GR Dens dated 22 Aug 2008 per Bob Dawson with BP Exploration (Alaska), Inc. (8) The sidetrack was drilled from v-115 through a milled window in a 4 1/2 inch liner. Top of window 8174 ft.MD .(6617.3 ft.TVDSS) Bottom of window 8180 ft.MD (6619.4 ft.TVDSS) (9) Baker Hughes INTEQ runs 4 and 5 were used to drill the lateral section on v-115L2P61. <10) The v-115L2 was drilled from v-115L2P61 as an open holes sidetrack at 8435 feet MD (6640.6 feet TVDSS). (11) Tied to v-115L2P61 at 8424 feet MD (6641.3 feet TVD55). <12) The interval from 10792 feet to 10832 feet MD (6636.5 feet to 6632.0 feet TvDSS) was not logged due to sensor to bit offset at well TD. (13) The resistivity interval from 8170 feet to 8450 feet MD (6616.0 feet to 6639.8 feet TvD55) was logged on run 4 18 hours after drilling.
