Item 1a: Classification of Service wells: Gas injection, water injection, Water-Alternating-Gas Injection, salt water disposal, water supply for injection, observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI (Top of Producing Interval). Item 8: the Kelly Bushing elevation in feet abour mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). Item 20: True vertical thickness. Item 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool Item 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 28: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-in, Other (explain). Item 27: If no cores taken, indicate "none".

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. The permit is for a new wellbore segment of existing well KRU 1C-28, Permit No. 205- 104, API 50-029-23270-00. Production should continue to be reported as a function of the original API number stated above. 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. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test.

We will need to wait to see exactly where we get successfully sidetracked and then will submit the 401 for the L1 orphaned wellbore.

I spoke with Steve Davies and you should plan to submit a 401 for the orphaned hole section naming it L1. I do understand that your intent i_s to proceed to the originally planned BHL but, as Steve reminded me, al.l segments need permits. Waiting until the end of the well is not the option I believed it might be. We will look forward to receiving the application. Continued operations are acceptable. Tom Maunder, PE AOGCC Billingsley, Tim A wrote, On 1Of31/2005 1:41 PM: Tom Maunder, On 1C-28, drilling was stopped at 15,378' MD because the rotary steerable assembly was not able to correct an upward trend in the drilling and the bit was alrlost out of the top of the Kuparuk C-4 zone. The last survey indicated the hole was at 95.3 degrees and still climbing even though t:he rotary steerable had been trying to drop angle. It was determined that we could not correct this wellbore without drilling a significant amount of "D" shale above the C-4 pay interval. The rotary steerable assembly was pulled and a motor with a 1.5 deg bend was run. An open hole sidetrack over the weekend was attempted at 15, 248' but was unsuccessful in sidetracking from the original wellbore. The BHA was pulled and a motor with a 1.83 deg bend will be run tonight (Monday October 31, 2005). The proposed plan is to sidetrack the well at approximately 15,130' MD and resume drilling the plan:aed well path with the 1.83 deg bend motor. The orphaned lateral from approximately 15,130' to 15,378' will not be plugged and will not be cased with a slotted liner. The orphaned lateral will be mosr_ly in Kuparuk C-4 reservoir. The 6-3/4" hole will be drilled from the sidetrack point to the planned TD of 18,953' MD with a slotted 4-1/2" liner run from TD to 150' above the 7-5/8" casing shoe at 14,781'. Please advise of any official applications/reports which will be needed once the sidetrack plan is successfully accomplished.
