CC: Art Saltmarsh <art_sattniarsh~actmin.state.ak.us>, .Fim Regg <im_ regg~ci„admin.state.ak.us> Mark, I have looked at your Area of Review determination. I have used the information available in the AOGCC well files to perform my own assessment for comparison. The Commission well files for the listed W pad Ivishak wells do not have a lot of detailed information regarding the cementing operations and no formation top information for the shallow horizon objectives. I would appreciate if you could provide additional information concerning the cementing operations and formation tops on the Ivishak wells. W-203 and its laterals are the newest wells identified for the AOR. I agree with your assessment on W-203. Using 30% XS factor, I also agree that the TOCs for W-OS and W-O1 are likely around 4500' tvd and that the TOC for W-08 is likely below the Schrader. For W-07, I calculate a TOC near 4650' tvd. Details comments for each well are included below. I look forward to the additional information. On receipt, I should. be able_to conclude the AOR evaluation. I would also appreciate if you would have another look at the information for W-07 so we can reconcile. Call or message with any questions. Also, is the potential spud date still around January 20? Tom Maunder, PE AOGCC ~~'~~+~ ~~ A ~? ~' ~ O 1 ------------------------------------------------------------- ~~av~ W-203 (202-097)--The AOGCC well file has sufficient information to verify AOR statements provided.. Based on 30% XS washout, the TOC in the 8-1/2" x 7" annulus would be about 5079' md. A USIT log was run in this well and indicates a TOC of about 5235' and which is about 4000' tvd in agreement with the provided AOR statement. Based on the 5300' and TOC, the XS hole size is about 40%. The L2 window top is at 7120' and (5030' tvd). ----3-~ ~-'------------------------------------------------- W-O5 (189-043)--The AOGCC well file does not have sufficient information to verify AOR statements provided.

File does indicate that the plug was not bumped and cement was tagged at 11279' (1494' above FC). This essentially means that no tail slurry was pumped outside the casing. Using only the lead cement volume and 30% XS washout, the TOC in the 12-1/4" x 9.625" annulus would be about 7131' and (5200' tvd). ------------------------------------------------------------- W-07 189-019)- The AOGCC well file does not have suf(fi~cient information to verify AOR 1.~1~1 ~.Gs'C'~~a:~G.~ ~~~ G`~C~~.Cjl` ~C.t ~)~C~~S p~ J~~1C.~S Sl~ti~ I of 2 ~ a 1/8/2007 2:09 PM Re: [Fwd: W-2101 Area of Review] statements provided.

I wrote up the word document that basically summarizes the cement integrity of the wells within 1/4 mile of W-210i. The powerpoint has an annotated W-210i map. Our geophysicist created the map, and this is what he said - "I chose the Top OBa interval (highest injection zone) to show W-210i in relation to it's neighbor wells. The map is pretty busy - I only showed the well spiders for W-210 and the wells w/I the 1/4 mile circle -you can zoom in to see the detail. There are dots on the map to show where each well is at TopOBa. I can easily make other versions to show the same sort of thing for the Top of the Pool/PA (UG_Mc Top), or any other Schrader zone." Let me know if this information is sufficient, or if more information will be needed.

Contact the Commission's petroleum field inspector at (907) 659-3607 (pager). As provided in AS 31.05.080, within 20 days after written notice of this decision, or such further time as the Commission grants for good cause shown, a person affected by it may file with the Commission an application' for rehearing. A request for rehearing is considered timely if it is received by 4:30 PM on the 23rd day following the date of this letter, or the next working day if the 23rd day falls on liday or weekend.

The well is shut-in due to corroded tubing and leaks. The well last produced continuously in 2001 at rates of200-250 BOPD at roughly 6000 scflstb GOR (including lift) and 40-50% water cut. I calculate 200 MSTB reserves remaining assuming a limit of 100 BOPD. The planned horizontal sidetrack will access the current reserves plus additional beyond this wellbore. Plug-back of this well will not cause waste and there is sufficient information to approve this sundry.

This well has been shut in since 2002 due to badly corroded tubing, with multiple hole~he 9 5/8" casing passed a CMIT to 2,500psi in 10104. The 9 5/8" casing pack-off passed a PPPOT to 3,500psi in 11/04. / Additionally, the original well is thought to be drilled down a fault plane. The planned sidetrack, to a new BHL, is thought to be more economic than a simple RWO. Obviously, the corroded tubing will be replaced during completion. The W-07A sidetrack is scheduled for Nabors 7ES. Current estimates have it beginning around August 01, 2005, following the completion of rig summer maintenance. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Scope Notify the field AOGCC representative with intent to plug and abandon Pre-Ri~ Operations: 1. The 3 Y2", 9.2#, L-80, TDS tubing is badly corroded from -1,500'md to -3,900'md, based upon a caliper survey run April 01, 2004. There are multiple holes in the tubing throughout this range. 2. R/U coiled tubing. RIH and plug and abandon th~J}érí)erfOrations (112') with 15.8ppg class 'G' cement. The estimated cement volume required i . 0.5. Is, minimally.

Dear Mr. Stagg: Enclosed is the approved application for permit to drill the above referenced well. The permit to drill does not exempt you from obtainin~g additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting deteznninations are made. 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.
