Please see corrected surveys for PBU 04-29A, 04-29AL1 and 04-29AL1PB1, if you have any questions please don’t hesitate to let me know. Thanks!

That work has not been completed yet. The IA leak rate was too small to measure @ 3000psi last time it was checked. Tubing held to 3000 psi last time we checked. Both those tests were done in 2007 and need to be redone. A leak detect log showed a leak @ 9974' which is suspiciously close to liner top packer depth. Step 5 in the main procedure is testing a 9.625" bridge plug @ probably 2500'. If the pre-rig IA test fails we'll move the packer test up from step 11 in rig portion of the program and find our leak(s). Terrie left copies of the 2 sundries she filed for this well on my desk, so you should already have the dual paperwork. Hope that answers your questions. Dave Bjork will be taking this well so let him know if it doesn't. Thanks, Hank Baca Drilling Engineer 907-564-5444 office 907-748-0997 cell From: Schwartz, Guy L (DOA) [mailto:guy.schwartz@alaska.gov] Sent: Monday, April 12, 2010 1:54 PM To: Baca, Hank Subject: 04-29AL1 RWO (PTD 200-178) Hank, In reviewing the RWO I did't see the current CMIT results listed. You state a IA X OA leak but don't indicate the rate loss or where it is located in the 9 5/8" casing. Will it hold 1000 psi ??? (ie step #5) Is the OA arctic packed?? Was curious as to what evidence there was for the liner lap leak too. Could you elaborate on this.... In addition the Sundry is written under the L1 lateral PTD. The motherbore PTD 04-29A) would be more appropriate but in reality the wellwork should be reported for both PTD numbers. Please submit another sundry for 04-29A . At completion wellwork reports (404's) will be needed for both motherbore and 04-29AL1. 1 realize this is some duplication but it keeps our well records complete. Don't hesitate to call if you have any questions. Thanks in advance.

Nothing further will be required. When the 407 is filed, this change can be captured there. Please call if there are any questions. Tom "Stagg, Ted O (ORBIS)" wrote: Tom, SLB/Nordic I has reached TD on MPF-73a at a depth of approx. 14,606'. This is approx. 600 ft shy of the permitted TD of the sidetrack. Drilling has been stopped at this point due to Iow resistivity of the Sag River interval targeted for this well. The completion plan has been modified from that described in the Permit to Drill (200- f 98). The 100% slotted liner originally planned has been changed to a combination cemented and slotted liner. Both the solid and slotted liners will be 2 7/8", no 3 3/16" will be used in this completion. The mason for the change is that a significant lost circulation zone was encountered at approx. 13, 640'. This loss zone was successfully sealed with a bentonite.cement treatment. However, to insure continued isolation from the loss zone a 2 7/8" solid liner will be run from approx. 300 ft above the window (top of 2 7/8" ~ 12,400) to approx. 150 fl below the loss zone, 13, 800. The solid liner will be cemented with a minimum of g bbls Class G cement. Slotted liner will extend from 13, 800' to TD at approx. 14, 606'. The cement portion of the completion will be perforated above the loss circulation zone, I am attaching a schematic of the planned completion. Please advise if further info is needed for this change in completion plans.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. The permit is for a new wellbore segment of existing well 04-29A, Permit No 195-172, APl 50-029-21453-01. Production should continue to be reported as a function of the original API number stated above. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The sidetrack, 04- 29aL1, will kick off from a window milled from a mechanical whipstock to be set in the Zone 1 interval of 04-29a. The 04-29aL1 target is lower Zone 1 to the west of 04-29a. The following describes work planned to prep 04- 29a for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack completion is attached for reference. 1. GLM's will be dummied off, the IA liquid packed and tested to 2500 psi. 2. Wellhead seals will be tested for integrity. 3. A dummy whipstock drift will be run to whipstock depth. 4. CTE-Line will set a mechanical whipstock at approx. 10,490' MD in the 7" liner. 5. No abandonment work will be done as the existing slotted liner will be retained to produce along with the sidetrack. CTE-Line is scheduled to set the whipstock on 11/6/00. Drilling coil is scheduled to move onto the well for milling/drilling on Nov. 13, 2000. Ted Stagg CTD Drilling Engineer CC: Well File Petrotechnical Data Center (' bp 04-29aL1 Sidetrack Summary of Operations: 04-29a is a Zone I horizontal slotted liner producer that suffers from Iow rate. The sidetrack, 04-29aL1 will exit the 7" just above the 4 ½" slotted liner and target Zone I sands to the west of the 04-29a completion. A flow-through whipstock will be used in order to retain production from the 04-29a slotted liner. This sidetrack will be conducted in two phases. Phase 1: Drift, set whipstock on CTE-Line. Planned for Nov. 6, 2000. · The IA will be loaded and pressure tested. · A dummy whipstock drift will be run. · CTE-Line will set the whipstock at approx. 12,490' MD (8820ss). Phase 2: Mill window, Drill and Complete sidetrack: Planned for Nov. 13, 2000. Drilling coil will be used to mill the window then drill and complete the directional hole as per attached plan. The sidetrack will be completed with a slotted liner. Top of 2 7/8" slotted liner to be approx. 12,210' MD (8702ss). Mud Program: · Phase 1: Seawater · Phase 2: Seawater and FIo-Pro (8.6 - 8.7 ppg) Disposal: · No annular injection on this well ..... · All drilling and completion fluids and all other Class II wastes will go to Grind & InjeCt~'; '? .~ ,:... ~'"i'./'" ;!i.'" i'"~.~, · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 2 7/8" slotted liner will be run from TD to approx. 12,210' MD (8702ss). 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 2000 psi. Directional · See attached directional plan. BHL (State Plane): 721,288; 5,952,021. Max. hole angle is 92 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray Icg will be run over all of the open hole section. · A real time Resistivity Log will be run in open hole and a memory CNL wil be run in cased hole. Hazards A 4-29a production test separator sample was measured at 25 ppm H2S on 8/28/98. The maximum H2S measured on test separator samples from DS 4 is 490 ppm on well 04-40 on 9/26/00. Lost circulation risk is Iow. The existing slotted liner will be sealed off with high vis FIo-Pro while drilling the 04-29aL1 sidetrack. Reservoir Pressure Res. press, is estimated to be 3365 psi at 8800ss. Max. surface pressure with gas (0.12 psi/ft) to surface is 2309 psi. 4-29aL1 Proposed Completion 4.5" 12.6# 13 Cr 9 5/8" window 10,174-10,239 Baker S-3 Pkr @ 12,168' 13 3/8"@ 2550 7"x 5.5" x 4.5" at 30' TRSV @ 2200' 6 Gas Lift Mandrels 34O4' 7312' 9401' 10529' 11194' 11620' 4.5 X Nipple @ 12,242' 4 1/2" WLEG @ 12,254' Top of Whipstock to be set approx. 12,490'.
