Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain).

Corr~niRRipn Anchoraq~ p-~ ~ ~9 ~ ~,"` Qs Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Z- 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.

I. Supervisor FROM: Lou Gdmaldi, SUBJECT: Petroleum Inspector SVS Tests BPX Z-pad Prudhoe Bay Field Saturday, April 21, 2001; I witnessed the three-month SVS retests on BPX Z pad in the:Western Operating Area of the Prudhoe Bay Field. 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 I 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 during next winter's cold season. 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, One failUre, 2,4% 34 Wellhouse inspections, no problems.

Supervisor O~l~-o \ Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Z Pad ~Fridav. January 19..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 Val.~e 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. ~ummarv: i witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13.9% failure rate. 2"i wellhouse inspections conducted.

Cleaning the well out and replacing with a sand plug per the program is not possible. Discuss with NRWO TL and Pad Engineer. Decision was made to continue with acid treatment using the scale as a plug back. Pull out of hole. Freeze protect and prepare for acid treatment. Rig up HB&R on IA. Rig in hole with BHA #4.

Install 20" diverter. The Drilling fluid program will consist of an 9.5-10.0 ppg spud mud in the 13- 1/2" hole, a 9.5-10.4 ppg water base mud in the 9-7/8" hole and a 9.5 ppg water base mud in the 8-1/2" hole. Drill 13-1/2" hole to 2700' MD and cement 10-3/4" 45# L-80 Buttress casing to surface. 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. Directional drill 9-7/8" hole to the 7-5/8" casing point above the Sadlerochit Sandstone. Run 7-5/8" 29.7# L-80 NSCC casing to within 10' of 9-7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dry crude. Directional drill 6-3/4" hole to TD. Run 5-1/2" liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Test casing and lap to 3000 psi. Change over to NaCL completion fluid. Run 7-5/8" production packer on tubing. Set packer 50' above top of liner. 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. Set and test packer. The well will be perforated with rig on location. Fluids incidental to the drilling of a well will be pumped down the 7-5/8" x 10- 3/4" annulus of the well.
