WELL HISTORY: There have been no prior RWOs or sidetracks on W-31. The well is currently shut in due to rock production because the liner is damaged. The tubing is corroded and needs to be replaced. Tubing currently has up to 50% penetrations over much of the tubing string. In January 2008, a CMIT TxIA failed when tested to 3500 psi. A LLR of 2 bpm 03100 psi was established. A leak detection log run on 6/16/08 determined the location of the leak at the packer. PROPOSED DRILLING & COMPLETION OPERATIONS: The W-31 wellbore will be plugged and abandoned from 10,947' to TD with cement. In order to conduct this planned sidetrack, the existing 4-1/2" L-80 tubing will be cut at 10,850', pulled, and a 9-5/8" bridge plug will be set around 9,810'. A whipstock will be set on top of the bridge plug and used to kick off the 8-1/2" intermediate hole section drilling BHA. After the intermediate hole section is drilled down to the top of the Sag River (-10,918'), it will be cased with 7" drilling liner and cemented to 9,640'. The 6-1/8" horizontal production hole will be drilled to TD (12,027') in Zone 4 before being cased with 4-1/2" 13-Cr, cemented, and perforated (300' minimum). The well will be completed with a 4-1/2" 13CR Production string Other Requests: Given rig floor height limitations, a MASP < 3000 psi, and the fact that the three ram drilling BOP configuration is preferred to a two ram configuration with a spool, BPXA requests a variance to the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the BOPE when existing wellhead or testing equipment prevents the testing of the YYY ___ ~'t, lowest set of pipe rams. If the lower set of pipe rams cannot be tested during the primary ~~ BOP test, that set of rams will be tested at the earliest opportunity during path-forward de-completion work, i.e., after the completion has been pulled from the well. Safety • concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the BOP stack. MASP: 2,892 psi W-31 A- Drill and Complete Procedure Summary Pre-Rig Operations: 1. RU a-line and run LDL to determine leak location (Done 6/16/08). 2. GLV stations #2-5 have all been replaced with dummy valves. GLV station #1 is currently open (AWGRS 12/25/07). The well is currently fluid packed with dead crude and diesel (AWGRS 1/5/08). 3. Replace open pocket of gas lift valve #1 with dummy valve and ensure IA is fluid packed for CT P&A. 4. RU slick line and pull the XXN plug (installed 12/25/07) from the XN-nipple at 10935'. 5.

The Permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other govern- mental agencies prior to commencing operations at the well site. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment ~so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe. ,, ~ ,, ~, ,,,~,~.~i¥'~U?~,,,~ Chairman Alaska Oil and Gas Conservation Commission BY ORDER OF THE CO~MISSION jo Enclosure C~ Department of Fish & Game, Habitat Section - w/o encl Department of Environmental Conservation - w/o encl STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION PERMIT TO DRILL 20 AAC 25.0O5 la.
