The original 1971 vintage F-04 reached GOR in 2001. The 2003 CTD Sidetrack F-04A was shut in for integrity in 2006. In 2008 a RWO was performed to cut and pull the production liner and change out the tubing. REASON FOR SIDETRACK Sidetrack to gain access the Ivishak Zn 1 reservoir to the west in an unswept portion of the reservoir. The proposed plan for F-04A is to drill a through tubing sidetrack with the Nordic 1 Coiled Tubing Drilling rig on or around September 01.2010. The existing perforations will be isolated by the pre-rig cement squeeze past the whipstock. The sidetrack, F-04B, will exit the 7" liner drill a 4.25" hole through the Kingak, run a 3-3/16" liner across Kingak_and drill a 3" hole to the target in the Ivishak Zone 1 A/1 B. The following describes work planned and is submitted as an attachment to Form 10- 403. Aschematic diagram of the proposed sidetrack is attached for reference.

Before even starting to mill the window we twisted off a motor shaft leaving a fish in the well. When Nordic 1 was unable to recover the fish the rig was moved off and service coil tried fishing. Those attempts failed also. / Summary of Operations: To resume operations on F-04a we are planning to lay additional 17 ppg cement to cover the fish and provide for a cement ramp kick off in Zone 4. While the target interval remains the same as originally permitted, the kick off point will be higher. The new directional plan is attached. V" One fault, 15-25 ft throw, will be crossed in the horizontal section of F-04a. This fault orientation and throw suggest a minimal risk of lost circulation but may present a geosteering challenge in re-Iocating Zone 1 B on the far side of the fault. /"j Phase 1: Prep work.

Maximum hole angle will be 90 degrees. ~ Mud Program: · Phase 1: Seawater /....) · Phase 2: Mill with seawater/biozan, drill with Flo-Pro (8.~r1pg) Disposal: · All drilling and completion fluids and all other Class" wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: / The production liner y¡iH 23/8" ST-L from TD to approx. 8560'MD (7398 'ss). The liner will be cemented with a minimum 0:..13 bb to bring cement up to approx. 9,800' (8416ss) or about 210ft above the window. Well Control: · BOP diagram is attached. · Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. /' · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan. Max. planned hole angle is 91 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. /' Logging · MWD Gamma Ray will be run in the open hole section. Memory CNL will be run inside the liner. Hazards · The maximum recorded H2S on F Pad is 30 ppm on well F-43. · Zones 3 and 2 conglomerates may cause slow ROP, possible bit damage. · One small fault mid-polygon may cause lost circulation.

The coil sidetrack, F-04a, will exit the 7" liner in Zone 2 and target Zone 1 B. F-04a will be completed with a fully cemented 2 3/8" liner. The existing F-04 perfs will be cement squeezed with a 17 ppg slurry desiged to be used as a cement ramp for the F-04a window. To prepare F-04 for the sidetrack, an X nipple in the production packer seal stem at approx. 8581' will be milled from 2.313" 10 to 2.75" 10. Additionally, the X-O from the production packer mill out extension to the 2 7/8" tailpipe will be milled such that the 2 7/8" tailpipe will be dropped off and chased to TO. With a recent TO tag at 10,510" , there is ample room for the 2 7/8" tailpipe in the 7" liner sump. One fault, 15-25 ft throw, will be crossed in the horizontal section of F-04a. This fault orientation and throw suggest a minimal risk of lost circulation but may present a geosteering challenge in re-Iocating Zone 1 B on the far side of the fault. Phase 1: Prep work. Planned for May 7, 2002. 1. Service coil to mill XN nipple and X-O ~ove tailpipe, push tailpipe to TO. 2. Service coil to lay approx. 25 bbls 17 ppg cement to shut off perfs and provide a cement whipstock ramp. I Phase 2: Mill window, Drill and Complete sidetrack: Planned for May 15, 2002. Drilling coil will be used to mill the window then drill and complete the directional hole as per attached plan. Maximum hole angle will be 91 degrees. Mud Program: · Phase 1: Seawater /' · Phase 2: Mill with seawaterlbiozan, drill with Flo-Pro (8.6 - 8.7 ppg) 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. Casing Program: The production liner will b;ë 3/8" ST-L from TO to approx. 8560'MD (7398 'ss). The liner will be cemented with a minimum of 10 bbls to bring cement up to approx. 1 O,OOO;,or about 150 ft above the window. Well Control: · BOP diagram is attached. /' · Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan. Max. planned hole angle is 91 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · MWD Gamma Ray will be run in the open hole section. Memory CNL will be run inside the liner. Hazards / · The maximum recorded H2S on F Pad is 30 ppm on well F-43. . · Zone 2 conglomerates may cause slow ROP, possible bit damage. · One small fault mid-polygon may cause lost circulation. ') ) Reservoir Pressure Res. press. is estimated to be 3272 psi at 8800'ss (7.2 ppg emw). Max. surface pressure with gas (0.12 psi/ft) to surface is 2216 psi.
