F !Ara. _slo(1 Subject: Corrosion Inhibitor Treatments of GPB Y Pad cgr)1 40 1 Dear Mr. Maunder, - i 4- L3 Enclosed please find multiple copies of a spreadsheet with a list of wells from Y Pad 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, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

Y-14B will extend the wellbore 2000' south, crosscutting Zone 4 to access waterflood reserves in 2 separate fAu~t blocks. When dTilled Y-14B will be completed with a 2.7/8" perforated liner tied back into the 4.1/2" perforated liner. The well operations are detailed below. Drill and Complete extension: Planned for June11,2001 2.3/8" coil tubing will be used to drill and complete the directional hole as per attached plan. The 3.3/4" hole will be completed with a 2.7/8" perforated liner, the top of which will be set in the 4.1/2" perforated liner at approx. 10,960' MD. Mud Program: · FIo-Pro (8.6- 8.7 ppg) Disposal: · No annular injection on this well. · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 2320' of 2.7/8", 6.4#, L-80, ST-L perforated liner from TD to 10,960' MD Well Control: · BOP diagram is attached. · Pipe rams, blind rams and the CT pack off will be pressure tested to 300 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2000 psi. Directional · See attached directional plan · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · A MWD Gamma Ray log will be run over the entire open hole section. · A real time resistivity or memory induction log will be run in the lateral section.

Reservoir Pressure Res. press, is estimated to be 3650 psi at 8800ss. Max. surface pressure with gas (0.12 psi/ft) to surface is 2594 psi. Y-14B CTD Sidetrack Hazards Pre-job HAZOP's and Safety meetings are recommended when there is a clear change in workscope. If at any time things don't feel or look right, stop the job and discuss the situation before making the next move. SAFETY FIRST. · 3650 psi @ 8800' TVDss is the BHP prognosis - equivalent to a 8ppg fluid. · 2595 psi is the maximum WHP possible assuming a full column of 0.12 psi/ft gas. The wellpath crosses 4 faults each with a less than moderate Iow circulation loss potential. Good drilling practices & Iow ECD's should be used to manage losses. · Pressure along the wellpath is predicted to be constant. · H2S content is 20 ppm. · Flammable Fluid Properties Fluid Flashpoint Vapor Pressure _< 1.5 psi Reed Vapour Press - Down Coil Crude Variable < 2.0 psi Reed Vapour Press - Down Backside Diesel 100 deg F 0.1 psia @ 100 deg F MeOH 55 deg F 1.8 psia @ 68 deg F TREE = CIW WELLHEAD= MCEVOY ACTUATOR~ AX~soN KB'..

(3) Well Y-14B was drilled to TD at 12171' MD (8953~ SSTVD) on (4) The hole section from 11780' MD (8922' SSTVD) to 11642' MD (8911' SSTVD) was logged with Ultra Slim Multiple Propagation Resistivity tool while pumping out of hole approximately 31 hours after the hole section was initially drilled. (5) No resistivity on the interval from 11900' MD (8931' SSTVD) to 12171' MD (8953' SSTVD) due to USMPR failure. (6) The data presented here is final and has not been depth shifted to a PDC (Primary Depth Control). As per BPX instructions, Gamma Ray RWD is the PDC for Y-14B boreholeo (7) A Magnetic Declination correction of 26.54 degrees has been applied to the Directional Surveys. 1.0 SURFACE EQUIPMENT: Main surface system software: MSS4 version 4.03 Memory dump system software: D-Series rev 1-03/PowerComms Rev DOWNHOLE EQUIPMENT: Natural Gamma Ray sensor:NaI Scintillation counter MPR Resistivity : 2 MHz and 400 kHz electronic wave RWD Memory rates: Gamma Ray 10 seconds MPR Resistivity 5 seconds Note: Each of the resistivity measurements has un upper limit to it's measurement specification° Above these values the traces can show an exagerated response. 2 MHz Resistivity from Phase Difference 3000 Ohmm 2 MHz Resistivity from Attenuation 500 Ohmm 400 kHz Resistivity from Phase Difference 1000 Ohmm 400 kHz Resistivity from Attenuation 200 Ohmm LOG ENVIRONMENTAL CORRECTIONS: Gamma Ray: Corrected for sensor type and collar size.
