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, Anna Dube, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator ~ ~ BP Exploration (Alaska ) inc.

I S Recover SL/fish Fish --- SL and Tubing Plug (lost 06- 25-2002) Surface tie-in for water injection The existing slotted liner completion was completed as a gas injection well in 02/1989. The well is presentily shut-in and will be converted to a water injection well for pressure support in the area. The well had a MITIA done on 01/05/2002 and passed. The well tree has been rotated. Recovering 1600' of slickline and a tubing plug is now in progress. Then the well will be tied-in, ready for water injection. A copy of the wellbore diagram is attached.

The existing completion, Z-33a, is a 5 1/2" horizontal slotted liner in Zone 4 that has been a gas injector since 1989. Gas injection was stopped in June 2001 and the well has been shut in since that time. Z-33b will be a near vertical water injector to support production from Zones 3&4a. If adequate oil column is encountered then Z-33b will be produced from Zones 3 and 4a until it makes sense to begin water injection. A 10-403 and a 10-401 were submitted on 12/27/01 for the Z-33b sidetrack. However, I would like to make a few changes to the plan that was submitted in the 10-403. I. may need to re-submit the entire 10-403, please advise. The changes are involved with plugging the existing 5 1/2" slotted liner prior to sidetracking. The completion interval for Z-33b will be >1000 ft measured and approx. 120 ft vertically deeper than the existing Z-33a slotted liner. The G&G and RE evaluation is that there is no reservoir management reason to fill the existing Z-33a slotted liner with cement. The Z-33b~linerwill be fully cemented to meet zone isolation requirements as a wa.te~injector-. Drilling does require that the existing Z-33a slotted liner be isolated enough to prevent loss of drilling fluid while the new sidetrack is drilled. To meet this objective I am recommending the following procedure to shut off the Z-33a slotted liner. 1. Static BHP survey will be run to confirm reservoir pressure. 2. MITIA will be performed to confirm tubing and casing integrity. 3. A cast iron bridge plug will be set in the slotted liner at approx. 9910' MD. This is opposite a Shublik shale that should be at least partially collapsed around the slotted liner. 4. Set a through tubing whipstock at approx. 9710' in the Sag R. interval. 5. Use~service coil to bullhead approx. 40 bbls 15.8 ppg cement to isolate the slotted liner. A .hesistation squeeze procedure will be used to achieve approx.~1000 psi squeeze required for washing out cement down to the whipstock. If this volume of cement is lost to the formation then the job~will be~repeateduntil losses to the Z-33a~completion are stopped. 6. Window milling will be done by drilling coil. The service coil prep work, steps 3-5, is scheduled for January 21, 2002 with drilling starting approx. Feb. 15, 200Z. A revised completion schematic is attached. Please advise if a corrected 10-403 should be submitted. Ted Stagg 564-4694 <<Z-33b Proposed Completion. ZIP>> TREE = 6" IWB-LHEAD = MCEVOYJ IF?,..=. .........................

Upon reviewing them I find a change or two that I would like to make with respect to how the existing slotted liner is put to rest. If possible, set aside the Form 10-403, dated 12/27/01, until I can make some changes and get the new plan to you. I will be working on that later this week and should have a revised plan to you by Friday, Jan. 4. We now don't expect to spud this one until mid-Feb so there is no great rush.

Supervisor'''~- Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit :Z'Pad Friday, JanUary 19j 200!:. I traveled to BPX's Z Pad in the Prudhoe Bay Field and witnessed surface, safety valve system' testing. Merv Liddelow was the BPX representative in charge of testing. As the attached AOGCC. Safety. Valve System Test Report indicates I witnessed the testing of 21 Wells and 43 components with 6 failures. The pilot on well Z-03 failed to trip and the pilot on well Z-08 was frozen and once thawed it passed a retest but the SSV on this well had an unacceptable closure time (12-min.). The SSV on well Z-18 also had an unacceptable closure time (15-min.) and the SSV's on wells Z-22B and Z-24 failed to pressure test: The high failure rate on Z Pad requires it be placed on a 90- day test interval. Mr. Liddlow indicated to me today that all failures have been repaired except the slow SSV closure of wells Z-08A and Z-18. The hydraulic lines on these wells need to be flushed and he has arranged for the maintenance crew to perform the work. Wellhouse inspections were conducted on the 21 wells tested with no exceptions noted. Summary: I witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13.9% failure rate. 21 wellhouse inspections conducted.

The pemit to re~i!l does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24~"hOurS'prior to commencing equipment installationso that the Commission may witness testing before drilling below the shoe of the conductor pipe.

PROPOSED PROGRAM: The Drilling fluid program will consist of a 9.5 - 10.4 ppg water base mud in the 12-1/4" hole and a 9.5 ppg oil base mud in the 8-1/2" hole. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. Directionally drill 12-1/4" hole to the 9-5/8" casing point above the Sag River Sandstone. Run 9-5/8" 47# L-80 NSCC casing to within 5' of 12-1/4" TD and cement using Class G cement. Perform mechanical integrity test. The 13-3/8" x 9-5/8" annulus will be freeze protected with dry crude. Directionally drill 8-1/2" hole to TD. Run 5 1/2" slotted liner with retrievable SBR and a liner hanger/packer from TD to 100' inside 9-5/8" casing shoe. Clean out to 5 1/2" shoe. Change over to 9.4 ppg. NaCL completion fluid. Run GR/CBT on wire-line from Top of Liner to 13 3/8" Shoe. Run 7" x 5 1/2" tubing with a production packer and a sliding sleeve. Set packer at a 50 degree hole angle. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Freeze protect tubing and annulus.
