'• tilAt ILL 8 20'1 Mr, Tom Maunder Alaska Oil and Gas Conservation Commission 333 West 7 Avenue Anchorage, Alaska 99501 Subject: Corrosion Inhibitor Treatments of GPMA Niakuk Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPMA Niakuk that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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 • w BP Exploration (Alaska) Inc.

The TIOs were 2160/2050/30 on 02/01/08. This well currently has an Administrative Approval to inject produced water with manageable TxIA communication. As previously discussed, the plan forward for this well is to allow the IA pressure to climb until stable to determine if an IA MAASP increase from 2000 psi to 2500 psi should be pursued. A 30-day TIO plot has been attached for reference. «NK-16 30-day TIO.BMP» Please call with any questions or concerns.

Box 196612 Anchorage, AK 99519-6612 ATTN: Jack Perrin I have compiled a summary of Anadrill's performance on Niakuk well NK-16 drilled on Pool 7. SERVICES PROVIDED Directional Survey Service (DSS) began at 65' on 4/15/95 and continued to 12787' Downhole weight and torque on bit (DWOB & DTOR) were added to the DSS service at 7886' to help optimize PDC bit efficiency and continued to 12787' to monitor bit condition while drilling through the tuffs. Realtime compensated dual resistivity (CDR) was added at 12019' and run to 12787' on 4/28/95. OPERATING STATISTICS Total MWD pumping time was 194.3 hours. Total MWD footage was 12722' over six bit runs. Total LWD pumping time was 34.3. Total LWD footage was 768' over one bit run. Total LWD below rotory table time was 66 hours. No MWD or LWD failures occurred during the well. ,lOB PERFORMANCE DIRECTIONAL The well was kicked off at 2605' with Anadrill providing tool face orientations, conventional surveys at connections, and real-time surveys while sliding. Conventional surveys at connections and real time inclination readings were continued while rotating through the tangent section of the well in order to minimize dogleg severity. A gyro was not run on this well so it was not possible to correct surveys to a gyro reference station. Two different MWD tools were run for external validation, with check shots taken each run at an established benchmark. The f'mal survey point was at 12699.49' with an inclination of 15.05 degrees at an azimuth of 55.03 degrees. The survey was projected to TD, giving the following bottom hole location: Measured Depth: 12787.00' True Vertical Depth: 9315.3~ Vertical Section: 6855.97' Latitude: 4778.80'N ,,~ ~ ~" E !V ~ Departure: 4916.24' E Displacement at Azimuth: 6856.12' @ 45.81 degrees P~l}2 0 ~ '}99§ Ala$~.0it .& 6as Gens. ,Anchorage DRILLING MECHANICS DWOB and DTOR services were run on this well to help optimize PDC bit efficiency and to evaluate bit condition while drilling through the tuffs. The Mechanical Efficiency Log (MFJ~) was used for this purpose, indicating a constant down hole torque was being applied to the bit with changes in formation and drilling parameters. The Sticking Pipe Indicator Log (SPIN) was also run to monitor trends in the rotating friction and drag of the drillstring so that anomalies could be identified for quick response. No sticking events were detected. SHOCK Very severe and persistent downhole shocks were encountered while drilling out of 10 3/4" casing 581,000 shock cycles in excess of 25g. Total down hole shock cycles measured during the well was 974,000. WASHOUT DETECTION Washouts can be detected when the MWD turbine voltage in monitored along with pump pressure and flow rate. No washouts were detected. Anadrill appreciates the opportunity to provide B.P. Exploration with MWD and LWD services.
