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 Master & Swab valve to 3500 psi. Drawdown test MV and SV to 0 psi 2. O PPPOT-T & IC 3. S Obtain SBHP 4.

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-115L1 & V-115L2- Coiled Tub 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.
