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?

I wrote up the word document that basically summarizes the cement integrity of the wells within 1/4 mile of W-2101. The powerpoint has an annotated W-2101 map. Our geophysicist created the map, and this is what he said - "I chose the Top OBa interval (highest injection zone) to show W-2101 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. Thanks, Mark Staudinger GPB Rotary Drilling (907) 564-4337 (907) 440-7403 cell ~ o - 1/8/2007 2:09 PM . .

The pennit to drill does not exempt you from obtaining additional pennits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required pennitting detenninations are made. Annular disposal has not been requested as part of the Pennit to Drill application for Prudhoe Bay Unit W-203. 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.

Well Control A. The Schrader Bluff in this fault block is expected to be normal pressured at 8.6 ppg EMW. This pressure is estimated based on the initial static on W-200 (Dec-99). ' II. Hydrates and Shallow gas A. Hydrates have not been a significant issue thus far on W-Pad during the recent drilling of W-211 and W -212, however there is always a potential. III. Lost Circulation/Breathing A. Lost circulation is unlikely. B. Breathing will not be an issue as we are not drilling below the Schrader Bluff. IV. Kick Tolerance/Integrity Testing A. The 9-%" casing will be cemented to surface. The top of the 15.8 Ib/gal tail cement slurry is planned to be at -3,292' MD. B. The 7" casing will be cemented with 15.8 Ib/gal tail cement slurry to 500' MD above the Ma Sands -5,668' MD C. The Kick Tolerance for the surface casing is 53.3 bbls with 9.2 ppg mud, 11.6 ppg FIT, and an 8.7ppg pore pressure. D. The Kick Tolerance for the intermediate casing is infinite with 9.2 ppg mud. E. Integrity Testing V. Test Point 9-%-in shoe 7-in shoe Test Depth 20-ft minimum from 9-%--in shoe 20-ft minimum from the 7-in shoe Test type FIT FIT EMW (lb/gal) 11.6 minimum 12.0 minimum Stuck Pipe A. We do not expect stuck pipe. B. There could be slight differential sticking issues with the liners. Centralizers will be run to mitigate. VI. Hydrogen Sulfide A. W Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. Water injection on W -Pad was initiated in late 2001, and H2S levels are expected to remain low until the waterflood matures. Recent H2S data from the pad is as follows: B. Adjacent producers at Surface: a. W -12: less than 8 ppm C. Adjacent producers at TO: a. W -200: 0 ppm D. The maximum recorded level of H2S on the pad was under 20 ppm. VII. Faults A. The planned directional trajectory crosses two faults. These faults have been previously crossed at similar TVD's by W-01 with no problems associated with them. B.
