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, fop 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.

Z-24 (PTD #9890980) has been confirmed to have IA repressurization while shut-in. The wellhead pressures were tubing/IA/OA equal to SSV/2770/90 on 06/10/09 when the IA pressure was bled from 2770 psi to 2030 psi and repressured 340 psi. Given the checks in the gas lift valves are open on shut-in welis stacked out with gas lift, this is not an unexpected situation. The well has been reclassified as Under Evaluation. We wiil attempt to wait for the GC2 planned shut-down for maintenance to be completed (estimated to be June 29th). Then the well be POP'd so that another TIFL can be conducted with the well online before taking action to change out gas lift valves that might hold once returned to production.

We will attempt to wait for the GC2 planned shut-down for maintenance to be completed (estimated to be June 29th). Then the well be POP'd so that another TIFL can be conducted with the well online before taking action to change out gas lift valves that might hold once returned to production. The plan forward includes: 1. WIE: Monitor GC2 TAR schedule, evaluate if there is time to wait to POP well 2. Operations: POP well post TAR D: Re-TIFL with well online and unloaded A Wellbore Schematic and TIO Plot have been included for reference. «Z-24.pdf» «Z-24 TIO Plot.doc» Please let us know if there are any questions.

Merv Liddelow performed the SVS tests today. The test results (one SSV Failure) are noted on the accompanied SVS test spreadsheet. All well houses were in "OK" condition. This was the first experience ! have had with the new SV control system on Z pad and found it to operate quite well. The temperatures today were somewhat mild (+15)-and it remains, to be seen how they will hold up dudng next winter's cold seaS;3'n. WellS Z-5 and Z-8 had Slow clOsing SSV's (+ 2 minutes), Merv called the Automation crew and these were being worked on before I left the pad. The pad is being used as a staging area for some pipeline fabrication and has some equipment and material stored on it. This was kept for the most part neat and orderly. SUMMARY: I witnessed the three-month SVS retests on Z pad in the Prudhoe Bay Field. 20 wells, 40 components, OnefailUre, 2,4% 34 Wellhouse inspections, no problems.

Supervisor Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Z Pad Friday, JanUary 19j 2001: 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.

RIH, saw nipples on the way in. Could not get back up through btm X nipple. Circulated 15 bbls acid around tool string, able to get through. The acid seems to have done a job, but nipples still required 10,000g overpull and hitting at 80 fpm to get thru. Could not get down thru btm X and decided to come out of hole. While at Surface, displaced acid back into hole. Found packer rubbers missing and bands balled up. Fished packer rubbers with WL, except one small piece of rubber approximately 1" x 3". Note: upon disassembly of packer, found a stone (not cement) measuring 1/2" x 5/8" x 1/4" in packer. This caused packer to partially inflate. It is believed that this was not the initial cause of our problem being stuck, but it was the reason we could not later go back down through the nipples. Run packer//2, locate at EOT, correct to middle of packer element. Wash across perfs w/20 Bbl. acid. Took 29 M# to pull through X- nipple. Once at surface, found packer had never inflated. Recovered all rubbers except the small one, l"x8". Run packer #3 without TEL. Before RIH, pump 25 bbls water down BS to be sure tubing is clear of rubber piece. RIH and pump 20 bbls to warm CT. Drop ball, everything went textbook except packer did not set. POH. Pulled wt at 9300 ft and 9200 ft. Once OOH, found both large packer rubbers (7" long x 2.5" diam) and 1.5 of the small (1" long) rubbers missing. No indications of the packer ever having inflated. Run packer #4. Locate EOT and correct depth counter to middle of packer element. Position packer at 10575'. drop ball to set packer. Packer set. Treat down coil tubing w/18 bbl. 95% Xylene + 5% MS- 10 followed by 67 bbl. 15% HC1 + 10% xylene, flushed w/35 bbl. Sea Water. AIR 1.7 BPM @ 2800 psi.

Ct,',.~h/A,.~ BP Exploration is requesting administrative approval, as outlined on Conservation Order No. 213, Rule 2, to waive productivity profile requirements for three new wells. A waiver is requested for the following wells perforated in one single interval: Z-24 (31' TVD), Z-25 (26.' TVD) and Z-32 (28' TVD). In these cases, the value of obtaining a production profile would be limited. We are monitoring the production behavior of these wells. If production characteristics change sufficiently to warrant some kind of remedial work, we would obtain any required production logs at that time. if you require further information, please contact S.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operattona until all other required permitting determinations are made. 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 installation so that the Co~tssion may witness testing before drilling below the shoe of the conductor pipe.
