At some point during normal operations the conductor subsided about 12". With approval, the conductor extension will require the following general steps: 1. Remove landing ring from conductor if necessary. 2. Examine surface casing for any corrosion damage if it is exposed. 3. Extend the conductor to starter head. 4. File 10-404 with the AOGCC post repair.

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 June 26~', 2009. The corrosion inhibitor/sealant was pumped June 30th & July 16~', 2009. The atta.ched spreadsheet presents the well naxne, top of cement depth prior to filling, and volumes used on each conductor. ~ Please call MJ Loveland or Perry I~lein at 907-659-7043, if you have any questions.

This well will be operated as a Class II UIC well in compliance with Area Injection Order No. 2. Water will be injected for the purpose of enhanced recovery into the Kuparuk interval between the depths of 10452' and 10482'. This interval correlates with the strata found in ARCO's West Sak River State Well No. 1 between the depths of 6474' and 6880' as authorized in Rule 1 of this injection order. A Mechanical Integrity Test was performed before injection was initiated and and will be performed every four years hereafter, in compliance with Rule 6 of this order. This well's injection volumes, average injection pressure, and average annulus pressure will be reported to the AOGCC monthly. R. ECEJVED Gas Cons.

The test was started before I arrived and at my request all components were retested. The test went well with all equipment observed functioning properly and holding its pressure test. There was reluctance on Charlie Dicksons part to perform a Iow pressure test on the BOPE due to it not being written into the state regulations. I attempted to explain that a Iow pressure test has become a industry standard and is in line with good drilling practice, i also showed him the directive from Blair Wondzell to the Inspectors requirF~ing us to insure a Iow pressure test is performed during the BOP tests. Mr. Dickson still felt that if it was to be part of a normal BOP test a official letter would be needed. I made a field call and required the tes~o include a Iow pressure test. Recommendation: A letter to Arco Alaska drilling explaining our testing requirements. Summary: I witnessed the weekly BOP test on. Nordic rig #1. Test~e 2 hours, no failures. .

The permit to drill 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 1918 psi could be reached. Therefore, ARCO Alaska, Inc. will test the BOP equipment to 3000 psi. The nearest well to 3H-31 is 3H-21. As designed, the minimum distance between the two wells would be 11.2' @ 325' MD. 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 225 sx of cement followed by arctic pack upon completion of fluid pumping. *Spud mud should be adjusted to a FV between 50-80 sec/qt to drill gravel beds.
