BOX 100360 ANCHORAGE, ALASKA 99510-0360 November 1 Z, 2008 Mr. Tom Maunder Alaska Oil & Gas Commission 333 West 7th Avenue, Suite 100 Anchorage, AK 99501 ,-.~~~~ ~~t ~ ~ ~~Q~ Dear Mr. Maunder: tga'0ti`~ ~ ~~~ 3 ~" Enclosed please find a spreadsheet with a list of wells from the Kuparuk field (KRU). Each of these wells was found to have a void in the conductor. These voids were filled with cement if needed and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous. agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The cement was pumped starting March 13, 2008 and the corrosion inhibitor/sealant was pumped starting November 10, 2008. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor. Please call MJ Loveland or Perry Klein at 907-659-7043, if you have any questions.

The permit to redrill 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. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope Pager at 659-3607.

Maximum anticipated surface pressure is calculated using a surface casing leak-off of 13.5 ppg EMW and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would occur before a surface pressure of 2146 psi could be reached. Therefore, ARCO Alaska, Inc. has tested the BOP equipment to 3000 psi. The nearest well to 3R-12 is Oliktok Point 2A. As designed, the minimum distance between the two wells would be 316' @ 5,780' MD. The wells would diverge from that point. Incidental fluids developed from drilling operations will be hauled to the nearest permitted disposal well or will be pumped down the surface/production casing annulus of the last well drilled. That annulus will be left with a non-freezing fluid during any extended shut down (> 4hr) in pumping operations. The annulus will be sealed with 175 sx of cement followed by arctic pack upon completion of fluid pumping. REC£[V£D FEB - ? t99~, Alaska Oil & Gas Cons. Anchorage A CO ALASKA, Inc.
