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, Gerald Murphy, at 659 -5102.

We ran 8 joints 1-1/4" Hydril tubing to the final depth of 264' (RKB) , washing each joint down with fresh water and was unable to make any further progress. Flushed the 13-3/8" x 20" annulus (80' below ground level)-(14.6 bbls) and 156' of 13-3/8" x 16" hole (11.6 bbls) with 58 bbls fresh water using Dowell. Mixed & pumped a total of 46.0 bbls (57 sacks) Lead cmt mixed @ 10.7 ppg. Had good 10.7 ppg cement returns to surface after pumping 26.1 bbls cement. Pulled out of the hole and the fluid level dropped 4". I have attached a picture of the cement to surface. If you need anything else please let us know. «MVC-253X.JPG» Mike Thornton / Granville Rizek Doyon 141 Company Man Rig; 907-659-7170 Fax; 907-659-7103 Content-Description: MVC-253X.JPG Content-Type: image/jpeg Content-Encoding: base64 1 of 1 7/11/20054:06 PM MVC-253X.JPG (JPEG Image, 1024x768 pixels) i I ! ~ , 'i I. ..Jr' 1 of 1 7/11/20054:08 PM Re: No cement to surface on lE-117 13-3/8" casing. Doyon 141 Company Man wrote: Jeff Jones, As per our conversation, We did not get cement to surface. It was very close but no true signs of cement, our 10.5 ppg MudPUSH with Red Dye was 155 bbls late from 16" gauge hole and weighing up to 10.2 ppg. We should have got ± 302 bbls cement to surface. The returns were very thick and we lost returns 86.2 bbls (Plugging up in the hanger) prior to bumping the plug. Our plans are to remove the diverter and run 1" Hydril tubing as far as possible in the annulus of the 13-3/8" x 20" conductor and perform a top job bringing cement to surface as you requested. After we complete the job we will send a follow up e-mail. */Mike Thornton/*/ / Granville Rizek/ /Doyon 141 Company Man/ /Rig; 907-659-7170/ /Fax; 907-659-7103/ Hello Mike, please indicate in pumped for the top Thanks, Jeff Jones AOGCC your follow up e-mail the methods used and quantity of cement job and please attach a photo showing cement to surface. 1 of 1 7/11/20054:09 PM · STATE OF ALASKA A ALASKA ~L AND GAS CONSERVATION COM~ION WELL COMPLETION OR RECOMPLETION REPORT AND LOG ... ... 1a.

In addition a LCM pill composed of "G Seal" may be placed across the Ugnu, West Sak and Stump Island sands to help arrest mud dehydration if losses were experienced while drilling these intervals. ~ Ensure a minimum hydrostatic equivalent of 10.8 ppg on the HRZ during pumping of any pre cement pushes, etc. Losses of hole integrity and packing off can result from a reduction in hydrostatic pressure while pumping spacers and flushes. ~ Once hole conditions are ascertained consider dropping the excess to 30% if possible to reduce the chance of cement entering the Surface shoe. Job 7: Set Whipstock and Drill Production Hole Reference RP .:. "Standard Operating Procedure for Leak-off and Formation Integrity Tests" .:. "Prudhoe Bay Directional Guidelines" .:. "Lubricants for Torque and Drag Management" .:. ERD Recommended Practice Section 5.2 Operating Practices .:. Whipstock Sidetracks- RP Issues and Potential Hazards Y A whipstock will be set in the 7" intermediate casing to facilitate kicking off the horizontal production hole. Once milling is complete, make sure all BOP equipment is operable. Wash out BOP stack to remove any metal cuttings which may have accumulated there. .:. This will be Bakers new style of window milling assembly. Milling procedures will be slightly different than previous system. Discuss procedures with on site Baker representative before tools are picked up. :Þ- There are no "close approach" issues with the production hole interval of P2-43. :Þ- Calcium Carbonate will not be pumped at any time during this interval. The only exception would be if severe losses are encountered. :Þ- Expect a certain amount of geo-steering , but significant changes to the planned directional profile should be discussed with the Operations Drilling Engineer. There is a fault past the end of the polygon that should be avoided. The TD of the directional plan (which is the end of the Geo polygon) is a hard line. Do not cross. Job 9: Install 4-1/2" Production Liner Reference RP .:. Baker Bonzai running procedure (separate attachment to this program) .:. Schlumberger Cement Program. P2-43 Permit to Drill Version 1.0 Page 10 . . Issues and Potential Hazards ~ The completion design is to run a 4-1/2", 12.6#, L-80 IBT-M combination of solid and slotted liner throughout the production interval. ~ Differential sticking is possible. The 9.4 ppg Flo-Pro SF will be -200 psi over balanced to the Kuparuk formation. Minimize the time the pipe is left stationary while running the liner. ~ Ensure proper pre-job meetings have been held with all rig personnel and contractors so everyone will know their role once the liner is on bottom and setting / cementing procedures begin. Consult with Baker representative and ensure they have the latest Bonzai running procedures and tally book "cheat sheet" on location. ~ Sufficient solid 4-1/2" liner will be run to extend -150' back up into the 7" liner. Job 12: Install Completion Reference RP .:. "Completion Design and Running" RP .:. "Casing and Tubing connections" RP .:. "Freeze Protecting an Inner Annulus" RP. Issues and Potential Hazards ~ Diesel will be used to freeze protect the well to -4397' MD / -4150 ssTVD'. The diesel flash point is 1000 F. Diesel vapor pressure is - 0.1 psia at 1000 F. There will be no GLM's in the tubing string so freeze protection will be pumped before setting the production packer. ~ Keep in mind that the Kuparuk interval will be open during the running of the completion. Watch hole fill closely, verify no light fluids are introduced down hole and verify proper safety valves are on the rig floor while running this completion. ~ The completion, as designed, will be to run a 4-1/2",12.6#, L-80, IBT-M production tubing string, stinging into the 4-1/2" production liner tieback sleeve. Job 13: ND/NU/Release Riq Reference RP .:. "ADW Rig Move" RP. Issues and Potential Hazards ~ Four wells (P2-41, P2-42, P2-44 & P2-45) will require surface shut-in for the rig move off P2-42. The closest neighboring wells are spaced as follows: P-42 at -15' to the North and P2-44 at -15' to the South. Care should be taken while moving off the well. Spotters will be used at all times. ~ Note on Barriers during the ND BOP / NU Tree procedures: · Tubing - Kill weight fluid and a TWC. · IA - Kill weight fluid, tested annulus and annular valve. · OA - Kill weight fluid, Zero pressure on annulus and annular valve. ~ Note on Barriers during the RDMO procedures: · Tubing - Kill weight fluid and a BPV. · IA - Kill weight fluid, tested annulus and annular valve. · OA - Kill weight fluid, Zero pressure on annulus and annular valve.

Method of analvsis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two thousand feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. W 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety ~ factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk-based safety factor :3 may be used, with client notification. g 3. All depths are relative to the planned well profile. c3 (1) ....

Method of analysis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two thousand feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. W 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety ;: factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk-based safety factor 3 may be used, with clie'nt notification. g- 3. All depths are relative to the planned well profile. <3 fi) -. Survey Proqram: Instrument Type GYD-GC-SS MWD + IFR + MS Start Depth 28.50'md 1,OOO.00'md End Depth 1,000.00'md 11,076.91'md ì:J ~. ~ ci .J""'!I>. (1) Close Approach Analysis results: Under method (2), all wells may flow. A Gyrocompassing tool is recommended for surface drilling to 1,000' md, and may be needed for a depth deeper than this, depending on offset well magnetic interference. All data documenting these procedures is available for inspection at the Drilling & Measurements Directional Planning Center. Close Approach Drillinq Aids to be provided: A drilling map and traveling cylinder will be provided. Checked by: Scott Delapp 02/07/05 . BP Alaska Anticollision Report .
