ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Altemating-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). ITEMS: The Kelly Bushing elevation in feet above mean low low water. 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: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: 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 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

Currently the well is shut-in and has production tubing that is collapsed at approximately 13,864' MD and has a failed 9-5/8" casing pack-off. A /' horizontal sidetrack is seen as the most viable option to restore well bore integrity, access additional reserves, and maximize value. P and A of the original wellbore will be accomplished by recovering the tubing from above the collapsed joint, setting a bridge plug just above the stub and pressure testing to 3500 psi and providing 150' of /' cement in the 7" x 9-5/8" annulus above this point during the cementation of the drilling liner. / The Z-30A sidetrack is currently scheduled for Nabors 7ES beginning around 1/15/03. The pre-rig work for this sidetrack will be priority scheduled immediately after the Application for Sundry is approved. Please contact me directly should any additional information be required.

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 dudng next winter's cold season; Wells z.5 and Z-8had Sl°W-;cloSing SSV's (+ 2 minutes), Merv called the Automation crew and these were being worked on before I left the pad.

Supervisor o~1~-o\ Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Z-Pad .Friday, JanUa.ry.. !9. 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. Value 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 th® 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. Summa~: I witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13.9% failure rate. 21 wellhouse inspections conducted. ,A,, ttachme~nt: SVS PBU Z Pad 1-19-01 JJ Alaska Oil and Gas Conservation CommiSSiOn Safety Valve System Test Report Operator: BPX Operator Rep: Mew Lid&low AOC~C Rep: Jeff Jones Submitted By: Jeff Jones Field/Unit/Pad: PBF/pBU/Z'Pad Date: 1/19/01 Separator psi: LPS 159 HPS """ ,, ',i ' '~ ~ -' ' h '- ',' i ,,, ,, ,, ,- ' i , , i ,", "', ~, '-,, ..... ,'."'t-', ,,,, .... ~::~'~:i"~'~"?'::-'' L---.: :--~:~:::--..,:'-..': ::;:=~,=~=:-.:-'~-;'-:'-".-.~,...." .:-:::~.,-.-.'.-: WeB' Permit Separ -' Set L/P Test Test Test Date Oil, WAG, Ol~J.

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 Sadlerochit Sandstone. Run 9-5/8" 47# NT80-S NSCC casing to within 10' of 12-1/4" TD and cement with Class G cement around the 9-5/8" shoe. The annulus will be freeze protected by dry crude. Directionally drill 8-1/2" hole to TD. Run 5-1/2" liner from TD to 250' inside 9-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Change over to NaCL completion fluid. Test casing and lap to 3000 psi. Run 9-5/8" 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 9-5/8" x 13- 3/8" annulus of the well.
