A 2008 RWO to change out corroded tubing resulted in a piece of tailpipe with a plug stuck in it, stuck in liner at 9600 MD. No communication with reservoir. Also an obstruction in the Unique machine overshot at 9500 MD. This obstruction is thought to be a partially milled piece of the liner tieback sleeve, milled somewhat lengthwise, laying across the wellbore. No access below 9500' MD. REASON FOR SIDETRACK Sidetrack to regain access to the reservoir The proposed plan for Z-03A is to drill a through tubing sidetrack with the Nordic 2 Coiled Tubing Drilling rig on or around April 10, 2010. The existing perforations will be isolated by the fish, cement, cement retainer, and the primary cement job. The sidetrack, Z-03A, will exit the 4.5" tubing tail and target zone 4. The following describes work planned and is submitted as an attachment to Form 10- 403. Aschematic diagram of the proposed sidetrack is attached for reference.

Final depth-corrected prints were never created. Re-Processed: December, 2003 Solution: GR depth shifts applied to ROPE data (GR and ROPE data now on depth) , Final data is now presented in LDWG format. Final depth-corrected presentations created. When this data was originally processed in 1997, the ROPE data was not depth shifted along with the GR data (The baseline curve is the Schlumberger GRBCS of 20-Sep- 1997) . The GR and ROPE data were then distributed, and a 12' -13' offset was observed between the GR and ROPE data. The GR depth shifts have now been applied to the ROPE data, and the GRMWD and ROP.MWD data are now on depth with one another. The data is now presented in LDWG format as well. Additionally, final depth-corrected prints were never created or distributed. Digital displays (.PDS files) have now beencreatecland are included on this CD. Hard-copy prints have also been distributed as per LDWG guidelines. Please let me know if you have any questions or concerns about this data.

Supervisor DATE: April 21, 2001 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 inthe 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 Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit · Z Pad Friday. JanUary. 19. 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 AOG_CC 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 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. Weilhouse 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.

Pumped 1st stage of Mud Acid Stim Program consisting of 31bbls 12/10 HCL/Xylene, 46bbls 9/1 Mud Acid, 31 bbls 5%HCL. Over flushed with 100 bbls 2% NH4CI spacer. Park coil above perfs. Pumped 12 bbls of 30ppg wax beads in HEC. Perfs completely blocked after 7 bbls gel/wax out of nozzle. Bled pressure down and tried to pump in slowly but injectivity less than 0.3bpm at 2500psi WHP. Decide to circ out the 5% HCL acid out of the coil and neutralize and attempt to flow the well back through Trico overnight. 2/28/98 RIH with jetting nozzle. Dry tag at 3250 PU and saw o/pull to 20k at 3087'. Start pumping hot water and work down through wax plug. Returns playing havoc with Trico. Large globs of wax seizing up flowmeters and sample ports. Coil stby while Trico flow back acid to clean-up. Decision taken to abort second mud acid stage and RD CTU. Suffered 5 gal oil/acid spill out of vac hose bleed port while driver was pH testing his Icad. Fluid bled back through leaking butterfly valve on vac truck. Notes: With hindsight we overlooked the wax diversion design. Only 52ft net perfs, 2SPF = 104 perf holes. 500lbs wax was too much for this new well. Aisc the particle size and shape was not optimal. The smallest pieces were 2 - 3mm and the largest 2mm by 20mm strips. This is very prone to plating out and jeopardizing the job. CT has been stuck in hole with this before. Dowell are currently checking out the rest of their wax supply. Long term we should consider sourcing an equivalent of BJ "Divert 1" as this appears to be more forgiving for diversion acid stims. & Pad operator of completion of work and to return to MI Injection.

The intermediate portion (RUN 1) ~as logged in 8-1/2 hole. The TD portion (RUN 2) was run in 6" hole after intermediate casing was set. This log (BHCS/GR) is considered the primary depth control for any future logs. Logged from 6990 - 3000 and 9700 - 10147 ft md. There are no open hole logs between 6990 - 9700 ft md. ***NOTE*** The AIT rssistivity is NOT CORRECT due to damage to the AIT while trying to spud through a bridge at 7000 ft. The log was not rerun at the request of the BP well site representative and the driller who recommended that the hole conditions was deteriorating and that casing should be set immedidately. A second tool was on location and was ready to run had the hole conditions been better. Since then the AIT tool has been sent back to Houston to be rebuilt. The 90 inch and the 60 inch investigation measurements are not present because the values are not correct. The other investigation depths are presented only for qualitative information and to aid with bed thickness determination. $ PAGE: **** FILE HEADER **** FILE NA~E : EDIT .001 SERVICE : FLIC VERSION : O01CO1 DATE : 97/10/15 MAX REC SIZE : 1024 FILE TYPE : LO LAST FILE : FILE H~ER FILE NUM~ER: 1 EDITED OPEN HOLEMAIN PASS Ail tool strings; Depth shifted and clipped curves; all runs merged; no cased hole data.
