The gas lift pressure is much lower than the 2500 psi test pressure applied in the unsuccessful MIT. Bringing the well on for cleanup is acceptable. If the rig is delayed into the the new year, it would be appropriate to consider where the well falls in the SCP rules and apply the approval/waiver process. Keep us informed regarding the wells performance (pressure behavior) and the anticipated arrival of N3 S. Tom Maunder, PE AOGCC NSK Problem Well Supv wrote, On 11/30/2005 5:36 PM: Tom: Kuparuk producing well 1 Q-04 (PTD 1842340) was recently sidetracked by the Coiled Tubing Drilling unit (Nordic 2). During the safeout for drilling T x IA communication was discovered, the repair of which was delayed until CTD was finished with the well. Subsequent to CTD a Leak Detect Log was ran which found a leak in the tubing. There were also indications two possible additional small leaks. Yesterday (11/29) a patch was set across the primary leak and today the MIT failed. We suspect the additional leaks are present and repairing these is not the preferred option. The well is now being considered for a tubing swap to replace the old with new (Nabors 3S). The T x IA communication is not severe; the 2500 psi MITIA equalized with the tubing pressure in 25 minutes. The well will require gaslift to produce and the communication is expected to have minimal impact on the lift performance. Of immediate concern is that CTD left the multi-laterals full of FloPro drilling mud. To prevent formation damage we would like approval to flow the well for a period not to exceed 14 days in order to fully clean up the perforations/laterals. The well will be shut-in and secured at that point until the workover can be performed. The ETA for the rig is expected to be near the end of December. Please let me know if we have approval to flow 1 Q-04 for a period not to exceed 14 days. Thanks!

After pressure stabilization expect a SBHP of 2400psi to 2500psi. Expect to encounter increasing pressure as lateral is drilled away from mother well. Max. expected pressure of 3100 psi. The EMW is 9.2 ppg at 6511' TVD (L1 invert point). Max. surface pressure with gas (0.1 psi/ft) to surface is 2449 psi. ,,- Variance request • BPXA requests a variance to the provisions of 20 AAC 25.036 (d)(4) THROUGH TUBING DRILLING AND COMPLETION. This is regarding the function pressure test requirement after the use of BOP ram type equipment for other than well control or equivalent purposes. The variance will not apply when the KRU 1(F04L1 & 1Q-04L1-01 Sidetracks -Coiled Tubing Drilling Revision 1 to include L1-02 lateral Revision 2 to include L1-03 lateral routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadvertently closed on a tool joint during routine operations.) While drilling 1Q-04 it will be routine to close the 2-3/8" combi rams (pipe/slip) on the BHA during deployment and undeployment. These activities will not compromise the integrity of the BOP equipment. Managed Pressure Drilling Managed pressure drilling techniques will be employed to provide constant bottom hole pressure by using ~ 8.6 ppg drilling fluid in combination with annular friction losses and applied surface pressure. Constant BHP will be utilized to reduce pressure fluctuations to help with hole stability. Applying annular friction and choke pressure also allow use of lighter drilling fluid and minimizes fluid losses and/or fracturing at the end of the long well bores. A hydraulic choke for regulating surface pressure will be installed between the BOPE choke manifolding and the mud pits and will be independent of the BOPE choke. This well has a tubing retrievable sub-surface safety valve that will be utilized to facilitate BHA deployments and liner running. However, it is still possible that deployment of the BHA under trapped wellhead pressure would be necessary. Pressure deployment of the BHA will be accomplished utilizing the BOP pipe/slips (2- 3/8" rams, see attached BOP configuration). The annular preventer will act as a secondary containment during deployment and not as a stripper. Operating parameters and fluid densities will be adjusted based on real-time bottom hole pressure measurements while drilling and shale behavior. The following scenario is expected at TD: • Estimated reservoir pressure: 3100 psi at 6511' TVD, 9.2 ppg EMW. • Expected annular friction losses while circulating: 1017 psi (based on 90 psi/1000 ft) • Planned mud density: 8.6 ppg equates to 2912 psi hydrostatic bottom hole pressure. - • While circulating 8.6 ppg fluid, bottom hole circulating pressure is estimated to be 3929psi or 11.6 ppg ~' ECD • When circulation is stopped, a minimum of 1017 psi surface pressure will be applied to maintain constant BHP. • • K RU 1 Q-04 L 1 /L 1-01 /L 1-02/L 1-03 Producer Proposed CTD Completion rev.2 H. 3-'h" Baker 'FVL' SSSV set at 1815 RKB, 2.812" ID 9-5/8" 36# J-55 casing @ 4622' G. 3-1/2" 9.3# J-55 EUE Srd Mod tubing w/ 3-1/2" x 1"Camco 'KBUG' mandrels F. 3-'/z" x 1-'/z" Camco MMG mandrel ConocoPhillips Alaska, Inc.

The geology has been very complicated and we are near TD with much less than plannedineeded pay. We would like to run slotted liner from TD to 10100' (L1-01}then kick off an aluminum billet and drill above the L1-01 wellbore. We would drill L1-03{?} from 10100-10700" then run liner up to the tail pipe. We are about 80°lo sure we want to go this route. There is about 250' left to drill in L1-01 and there is not much of a chance we'll get enough sand to make a decent well. Since we°II be making the final decision very late tonight l figured I should give you a little notice and ask for approval to move forward while we get the paperwork together for a permit. seen From: Thomas Maunder [mailto:tom maunder@admin.state.ak.us] Sent: Friday, October 21, 2005 7:14 AM To: McLaughlin, Sean M Cc: Steve Davies Subject: Re: 1Q-04L1 & 1Q-04L1-Ol CTD sidetrack Sean, It is acceptable to continue your operations.

Thanks for sending your question. Tom Maunder, PE AOGCC McLaughlin, Sean M wrote, On 10/20/2005 12:04 PM: Tom, Nordic Rig 2 is currently drilling L1 on 1 Q-04. This was planned as a L1(south) and L1-01 (north). The plan on the L1 leg was to drill through the A3 sand, crest in the A4 (only offtake in the A4 in this area), then drill back through the A3. We have encountered a hard ankerite stringer in the upper A3 and have poor WOB in which to drill the planned A3 tail. We are planning to TD this lateral in the A4 at 10900' and run a liner back to 10050'. We would then kick off the liner top and target the A3 sand. That would make this an L1-01 and the planned later to the south would then be the L1-02. I am working on getting a permit submitted but would like approval to move forward with this plan. Should I submit a permit for L1-01 and the current permit (205-140) be revised to reflect the name L1-02?

(2) All depths are Bit Depths unless otherwise noted. (3) All Gamma Ray data (GRAX) presented is realtime data. (4) Baker Hughes INTEQ utilized CoilTrak downhole tools and the advantage surface system to log this well. (5) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure and Downhole weight on Bit), a Directional and Gamma Sub, Ultra Slim Resistivity Sub and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (6) Data presented here is final and has not been depth adjusted to a PDC (Primary Depth Control log. The INTEQ MWD Gamma Ray is the PDC for this wellbore. (7) The sidetrack was drilled from 1Q-04 through a milled window in 3 1/2" liner. Top of Window 9070.1 ft.MD (6522.16 ft.SSTVD) Bottom of Window 9072.9 ft.MD (6524.09 ft.SSTVD) (8) The interval from 10573 ft.to 10597 ft.MD (6624.8 ft.to 6626.2 ft.SSTVD) was not logged due to sensor bit offset at TD.
