The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Mehreen Vazir, at 659-5102. Sincerely, Gerald Murphy BPXA, Well Integrity Coordinator • • BP Exploration (Alaska ) Inc.

I apologize for this office dropping the ball on these wells. Thank you for your patience in this matter, Ron Wilson WI Tech 659-5524 ------------------------------ We have recently completed a mid year review of MIT data from our inspection database to see how many injection wells may be in question regarding M1T timing. Results of our review relating to BP-operated fields are as follows: MITs are past due for the following wells (injecting as of 7/31/2006) 1) PBU 04-13; due 1/8/2006 2) PBU S-101; due 2/25/2006 3) PBU NK-13¡ due 5/4/2006 4) PBU X-36; due 5/20/2006 5) PBU R-25A¡ due 7/24/2006 The following shut in wells are past their due date for MIT 1) MPU H-06; due 2/28/2006 (S1 since 7/2002) 2) PBU WGI-01; due 4/22/2006 (81 since 12/12/2005) 3) MPU F-41; due 5/14/2006 (SI since 5/2005) 4) PBU S-31A¡ due 6/1/2006 (SI since 12/2004) 5) PBU P1-01¡ due 6/4/2006 (SI since 6/2006 for workover) 6) PBU Pl-25; due 7/2/2006 (SI since 6/2006) 7) PBU GC-02C¡ due 7/22/2006 (SI since 4/2006) A MIT for each well injecting on the list should be conducted as soon as practical¡ please notify the Commission for an opportunity to witness. Regarding SI injectors, the Commission suggests deferring testing (at least 2of4 9/25/20069:15 AM .~~. .- "., ~V~'VJ' V' VV~' ,~,,' 'VV'.' ~Jn \' ,'-' "'/'" . the Commission's witnessed test) until injection is recommenced and well conditions have stabilized. There's also two wells with MITs that have apparently been done (not witnessed) that we would like to have for our database: 1) PBU 03-10¡ MIT 9/30/2005 (CMIT IAxOA) 2) PBU 04-08¡ MITs (IA and OA) done per monthly injector rpt¡ date unknown As with all operating companies, the Commission is willing to work with you to take advantage of operating efficiencies in scheduling MITs (perform multiple MITs per pad¡ perform tests during the more temperate months; etc.). Feel free to call if you have any questions, and thank you in advance for your prompt attention to those MITs that are past due.

Well NK-13 was drilled and completed in October of 1996 as a conventional high angle well. The well has been shut-in since January of 1999 due to Iow oil rate and high water cut. The current production declines in Segment 3/5 and the reservoir model indicate that additional water support is needed in this area. The offset producers that should benefit from injection at NK-13 are in Section 22 & 23, Township 12N and Range 15E. As part of the injection plan produced water will be used initially and if needed we have the capability to use seawater in the future. These issues are included in the revised Area Injection Order. Currently, we are planning on obtaining a static pressure survey and performing a Mechanical Integrity Test. A Segmented Bond Log was run on October 5, 1996 and shows fair bond across the Kuparuk interval with excellent bond above and below the perforated intervals. We would like to begin injection once the facility changes have been made. These changes should be completed by eady February. If you have any questions conceming this Sundry Application, please don't hesitate to call me at 564- 5359 or email me at wamerdwC, bp.com. Sincerely, Dwight W.

BOPE Test Pool Rig 7 Niakuk NK-13 PTD 96-0134 Monday, September 2, 1996: I traveled to BP Exploration Niakuk NK-13 Well to witness the BOPE Test on Pool Rig 7. The 13 318" casing had to be pulled out of the hole due to hole problems, the hole was cleaned and condition and the casing rerun. Each joint of casing was circulated down from 4.700' to 5,100' during the second attempt, a DV collar was installed at 4,975' and the remaining casing run without problem. The casing was cemented in two stages and clean cement returns were received at surface. A copy of the BPX morning drilling report covering the running and cementing of the 13 318" casing is attached for reference. As the attached AOGCC BOPE Test indicates there was one Choke Manifold Valve failure. The valve was rebuilt and retested before drilling out the 13 318" casing shoe. I found the rig to be very good condition and well laid out. All access areas to the rig were being kept open and clean.

Original reservoir pressure is 4500 psi at 9200' SS (9.4 ppg EMW). The most likely reservoir pressureIbased on NK-14-- is estimated at 4130 psi (8.65 ppg EMW). NK-12a and NK-14 are shallow close approach wells and will be shut in during the close approach intervalIspud to +_2200'. NK-02 and NK-02a are also classified as close approach wells between 13,620'-14,760', however they are not considered a drilling hazard. These well are plugged and abandoned, and pass BP's Deep-Intersection Guidelines.

Conservation Order No. 356A BP Exploration (Alaska), Inc. Niakuk 13 . April 7, 1995 Amended August 9, 1996 BP Exploration (Alaska), Inc. submitted an application dated March 21, 1995 requesting exception to 20 AAC 25.055(a)(3) to allow drilling the BP Niakuk 13 development oil well to a producing location that is closer than 500 feet to a quarter section line in an undefined pool. Notice of oppommity for public heating was published in the Anchorage Daily News on March 23, 1995 pursuant to 20 AAC 25.540. No protests to the application were received. Conservation Order No. 356 granting the requested spacing exception was issued April 7, 1995. BP Exploration (Alaska), Inc. submitted a revised bottom-hole location for the Niakuk 13 well on July 22, 1996. The revised bottom-hole location also requires an exception to 20 AAC 25.055 because it is closer than 500 feet to a quarter section line. Notice of oppommity for public heating for the revised bottom-hole location was published in the Anchorage Daily News on July 25, 1996 pursuant to 20 AAC 25.540. No protests to the application were received. FINDINGS: The BP Niakuk 13 well as proposed will be a deviated hole drilled from a surface location 1342' from the south tine (FSL) and 970' from the east line (FEL) of Section 36, T12N, R15E, Umiat Meridian (UM) to a proposed producing location 4835' FSL and 944' FW of Section 23, T12N, R15E, UM and a bottom hole location 258' FSL and 506' FWL of Section 14, T12N, R15E UM, Conservation Order No. April 7, 1995 Amended August 9, 1996 Page 2 . Offset owners ARCO Alaska, Inc. and Exxon Company U.S.A. have been duly notified. An exception to 20 AAC 25.055(a)(3) is necessary to allow drilling of this well. CONCLUSION: Granting a spacing exception to allow drilling of the BP Niakuk 13 well as proposed will not result in waste nor jeopardize correlative rights. NOW, THEREFORE, IT IS ORDERED: BP Exploration (Alaska), Inc.'s application for exception to 20 AAC 25.055 for the purpose of drilling the Niakuk 13 well is approved as proposed.

A request for rehearing must be received by 4:30 PM on the 23rd day following the date of the order, or next working day ff a holiday or weekend, to be timely filed. The Commission shall grant or refuse the application m whole or in part within 10 days. The Commission can refuse an application by not acting on it within the 10-day period. An affected person has 30 days from the date the Commission refuses the application or mails (or otherwise distributes) an order upon rehearing, both being the final order of the Commission, to appeal the decision to Superior Court. Where a request for reheating is denied by nonaction of the Commission, the 30-day period for appeal to Superior Court runs from the date on which the request is deemed denied (i.e., 10th day after the application for rehearin$ was fried).

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. No agreement to change bottom-hole location is implied. 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. ~hyai~n~E~R-' )E COMMISSION dlf/Enclosures Department of Fish & Game,' Habitat Section w/o encl.

The SLIM1 GR was run for bit runs 1,2, and 3, and the CDR/ADN was run on bit run 4. The data from the SLIM 1 bit runs was combined into one file. The bottom quadrant measurements were used in the merged file, and all four quadrants were presented in the raw file. The SLIM1 GR data was presented as delivered from the field and was not interpolated. The merged data was depth shifted to a WA CH GR run SEP-96 from 18460' to 21165' and the shifts were graduated to O' offset at 7011'. $ $ PAGE: **** FILE HEADER **** FILE NAME : EDIT .001 SERVICE : FLIC VERSION ' O01CO1 DATE : 96/10/22 MAX REC SIZE : 1024 FILE TYPE : LO LAST FILE : FILE HEADER FILE NUMBER: 1 EDITEDMERGEDMWD Depth shifted and clipped curves; all bit runs merged.
