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.

It appears that the documentation of the notification did not make it into the drilling report. Documenting contacts with the Inspector so they "print" in the report is important. You relate in your message that the importance of properly documenting such contacts will be a subject of future meetings with rig personnel. This matter is closed. Call or message with any questions.

And as the day-time Wellsite Leader recalls (Duncan Ferguson who was the on rig at the time of this top-job cement job and happens to be on the rig today), Chuck was notified prior to the actual top-job cement job, however, he declined witness of the job when it occurred (note also that Chuck was on location later that day (6/6/08)to observe the BOP test). Also, let there be no doubt that we (BP) would not move forward with an operation of this nature without having the appropriate conversations} with your agency and as I recall, it was clear to this office that those conversations had occurred and that we did have a "green-light" from your agency to move forward with the top job cementing operations. What we could have done better, is the need to make better/more complete notations of any and all conversations with your agency personnel in DIMS as well as to follow-up these conversations with an a-mail and those points will be re-emphasized to both our Anchorage based and rig based personnel for all path-forward operations. I have attached a copy of the daily rig log/diary and a copy of the 6/6/08 DIMS report for your review and if you have any questions or concerns, please advise. Thanks - jr John ~i.

It is reported that the cement was not circulated to surface by the primary surface casing cement job ~ June 7, 2008. Although a port collar had been run, it was not possible to pump a 2"d stage cement job using it and ultimately 275' of 1" pipe was run into the annulus and 178 bbls of DeepCRETE was pumped with cement to surface. Neither myself or my colleagues have any record of having been notified that the primary cement operation was not successful as required by 20 AAC 25.030 (d)(4). Please examine your records with regard to the circumstances of this matter. We are particularly interested in ... 1. Why it appears that Commission was not notified of the unsuccessful primary cementing operation? 2. How 275' was determined as the cementing depth for the top job? If you determine other factors that have bearing on the operations, please include them. The Commission reserves its right to pursue an enforcement action in this matter. I look forward to your reply.

For the planned drilling of this well, 20" conductor casing has been set and cemented at ~80' at the B-37 surface location. From there, the basic drilling plan will include a 12-'/" surface hole to 3725' MD (SV3) where 9-5/8" surface casing will be run and cemented to surface. An 8-1/2" intermediate hole will then be drilled from the 9-5/8" casing shoe to the top of the Sag River formation 10,107' MD where a 7", 26.0# intermediate casing string will run and cemented with the proposed cement top to be 1000' below the surface casing shoe. A 6-'/e" production interval will then be drilled to the Zone 2 target with the final well TD at 10,865' MD where a 4-'/z", 12.6#, 13 chrome solid liner will be run and fully cemented. The planned completion for this well will include a 4-''h", 12.6#, 13 chrome tubing, four gas lift mandrels and an S-3 permanent packer. The B-37 well is currently scheduled for Nabors 7ES beginning ~02/O1/08. Please refer to the additional data within this request for specific well details and do not hesitate to call if I additional information is required.

As the B-02A, B-05, B- 05A and B-22 wells are all currently abandon, no additional wells will require sub-surface shut-in during drilling operations. Reference the Anti-collision report in the directional plan for a full list of offset well paths. B-37 Wellplan Summary 4 10/10/2007 Well Control Surface hole will be drilled with a diverter.

Well Control /Reservoir Pressures: Normal pore pressures (8.5 ppg) are expected throughout surface hole drilling operations. Normal pore pressures (8.5 ppg) are also expected throughout the intermediate hole drilling operations, however, Cretaceous injection pressures up to 9.4 ppg may be encountered from the top of the UG1 to the base of the West Sak formation. For the production interval of the well, the Ivishak reservoir is expected to be pressured to 6.9 ppg EMW. II. Hydrates and Shallow gas: No gas hydrates or shallow gas is anticipated, however, follow good drilling practices in the regards at all times. III. Lost Circulation /Breathing: Lost circulation on the surface hole cement jobs has been a problem on this pad. Well breathing problems are a possibility in the intermediate hole after weighting-up the mud to 10.6 ppg for the HRZ. Lost circulation in the reservoir section is considered low. Follow the RP guidelines for dealing with Lost Circulation problems when/if they occur. IV. Kick Tolerance /Integrity Testing: Intermediate Section Kick Tolerance and Integrity Testing Integrity Test- 8-1 /2" hole:LOT 20' - 50' from 9 g/e" shoe • Kick Tolerance: 67 bbl KT with a 10.6 ppg mud with an 11.2 ppg FIT/LOT (NOTE: Need a 12.5 ppg FIT/LOT to satisfy ECD management requirements.) Production Section Kick Tolerance and Integrity Testing • Integrity Test - 6-%e" hole: FIT 20' - 50' from 7" shoe • Kick Tolerance: Calculated an Infinite KT with an 8.5 ppg mud with 8.8 ppg FIT/LOT (NOTE: Need a 10.5 ppg FIT/LOT to satisfy ECD management requirements.) V. Stuck Pipe There will be some differential sticking tendencies across upper sands in the intermediate hole with the planned 10.6 ppg mud weight in the hole. Keep the pipe moving and follow good "practices" while drilling and running the 7" casing in this interval of the well. VI. Hydrogen Sulfide B-Pad is not considered an H2S pad (22 ppm in average) in line with WI operation policy. 8-01 last H2S sample ~ 50 PPM 05/10/2006. However, as B-Pad does have at least 1 well with greater than 100 ppm HzS (see below), the Standard Operating Procedures for HZS precautions should be followed at all times.
