We have drilled from a window depth of 9635' MD to a TD of 11,703' MD. We have chosen not to complete this Ivishak target due to insufficient pay, and we will instead drill our contingent Sag target 13-30C (PTD #2080870). Plans are to drill the Sag target via the same window at 9635'. AOGCC approval is requested this morning to plug the Ivishak target by setting an IBP at 9840' MD and laying in cement from the IBP to the window. We will follow-up with the 10-403 paperwork later today and attach your reply to this a-mail.

Oral approval on the abandonment can be handled fairly easily. You will need to send me some plan description via email so I can inform the Commissioners. With regard to the possible 13-30C, it makes sense to go ahead and permit the well so that timely part of the process can be completed prior to a potential spud. If you don't need 13-30C, it can be cancelled. Call or message with any other questions. Tom Maunder, PE AOGCC 7/17/2008 Question about permitting 13-~ • Page 2 of 2 From: Sarber, Greg J [mailto:SarberJG@BP.com] Sent: Tuesday, May 20, 2008 3:f7 PM To: Maunder, Thomas E (DOA) Subject: Question about permitting 13-30C Tom, I have a question for you. I am currently planning a horizontal CTD sidetrack of well 13-30A. The AOGCC has issued a sundry to abandon the 13-30A pertorations and a permit to drill 13-30B. The "B" lateral is an Ivishak zone 4 sidetrack targeting an unswept area of the reservoir that is assumped to be isolated by a fault. There is a possibility that when the "B" lateral is drilled, the formation will be found to have been swept by water flood, with no recoverable reserves. BP has developed an alternate sidetrack candidate, well 13-30C targeting the Sag River formation. This candidate lateral would be more than 500' away from 13-30B and in a different horizon. A PTD would certainly be needed for sidetrack 13-30C. 13-30C has not had a PTD application submitted yet. Ideally, if the "B" lateral is wet, the rig would abandon it, and proceed immediately to setting a whipstock and drilling the "C" lateral. To make most efficient use of the rig, it would be best to have continuous operations without having to put the rig on standby or move off the well while a sundry and PTD are obtained. My question for you is how is this best handled? If the B lateral is found wet, would BP need a sundry to abandon the uneconomic 13-30B lateral? Could the sundry be obtained verbally, then the paperwork submitted. Should BP apply for a PTD well 13-30C, even though it may not be drilled? I can call and discuss on the phone if needed.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). cerely, Daniel T.

That sidetrack will be 13-30B, which has been permitted by the AOGCC. The PTD # for 13-306 is 2080780. The target interval for the 13-30B sidetrack is the Ivishak zone 4 sand. That sidetrack is based on the assumption that there is a sealing fault that isolates unswept oil from the parent 13-30A wellbore.. If that assumption is proven false, and the sand to the south of the fault is found water wet, then the 13-306 lateral will be abandoned with a cement plug. There is an alternate target from the parent 13-30A well. This target is in the Sag river sand. That target is the one covered by this PTD application. The reason for this permit to drill is a contingency plan if 13-306 is found to be wet. The intention would be to immediately drill the Sag river target while the rig is still on location. That is the scope of this permit to drill application. Pre-CT Rig Work: (Scheduled to begin on May 29, 2008) 1. MIT-IA, -OA 2. Dummy GLV's 3.

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: 3.75" x 4.125" (bi-center bits used) in build section from 9,520'-10,400', 2.375" Coil Tubing 2.70" x 3.0" (bi-center bits used) in lateral section from 10,400'-12,000'. 2.0" Coil Tubing Casing Program: Protection Liner -Fully cemented • 3-3/16", L-80 6.2# TCII 9,650' and -10,400' md. • A minimum of 7.0 bbls of 15.8 ppg Class G cement will be used for the protection liner cementing. (Assuming TD at 10,400' and top of liner at 9,650') • TOC planned at the top of liner 9,650' • The purpose of the protection string is to avoid hole problems at the Shublik/Sag river sand interface. CTD has lost holes from ledging developing at this location. Production Liner -Slotted Liner • 2-3/8", L-80 4.6#, STL slotted liner 10,300' and - 12,000' and • No cement will be pumped on this liner, it is a slotted liner completion. • The liner top is planned to provide a potential future coil sidetrack from the 3-3/16" liner.

Directional • See attached directional plan. Maximum planned hole angle is 106.26 deg at 9,900'. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property -18,530' to unit boundry to south. • Distance to nearest well within pool - 500 ft. (Well 13-12) Logging • MW D directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole MCNL/GR/CCL logs will be run. Hazards • The parent well is a very prolific (+6000 bpd) water producer. Isolation from the parent is critical. This may require multiple cement squeezes to P&A the 13-30A lateral. This activity will be accomplished in pre-rig preparation work to ensure a good cement job. • The window will be milled in slotted liner. This is an unusual technique for CTD, and may require dressing runs with a tapered crayola mill. • The maximum recorded H2S level on DS 13-30 was 160 ppm on 2-2-2008. • The maximum recorded H2S level on DS 13 was 200 ppm on well 13-05 on 6-29-2002. Reservoir Pressure • The reservoir pressure on 13-30A was last recorded at 3,345 psi at 8,800' TVDSS in June 2007. (7.31 ppg equivalent) • Max. expected surface pressure with gas (0.10 psi/ft) to surface is 2,465 psi.
