Con~ni~~ion Anchcrap~ ~~' ~r ~~'~ ~ ~ ~~ 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.

Close blind rams and pressue up between blind rams and Halliburton storm packer set 30' below BOP stack to 3500 psi. Close in valves and observe pressure on gauge at drillers panel. 3. Bleed down all pressure on Outer Annulus below 9-5/8" packoff to 0 psi. 4. Pressure held at 3500 psi on 9-5/8" packoff and area between blind rams and storm packer. 5. Bleed down pressure between blind rams and storm packer to 0 psi and the pressure on the FMC gauge covering the test port bled down slowly to 0 psi indicating that the lower packing to the OA was holding and the upper packing to the area between the blind rams and storm packer was not holding. Consulted w/town engineer and decision was made to nipple down BOP and replace the tubing spool on the basis of the above test by: 1. Leaving the the 9-5/8" packoff in place secured by the lock down screws in the top end of the casing flange. 2. ND the tubing spool and the BOP stack above the tubing spool. 3. The lower seals on the 9-5/8" packoff serve as suitable barrier to any pressure or flow which might develop f/the outer Printed: 7/17/2006 1 :50:02 PM Legal Well Name: Common Well Name: Event Name: Contractor Name: Rig Name: Z-18 Z-18 WORKOVER NABORS ALASKA DRILLING I NABORS 7ES Start: 7/6/2006 Rig Release: 7/14/2006 Rig Number: Spud Date: 9/8/1989 End: 7/10/2006 21 :30 - 23:30 7/11/2006 23:30 - 00:00 00:00 - 01 :30 01 :30 - 02:30 02:30 - 04:30 04:30 - 06:00 06:00 - 07:00 07:00 - 09:00 2.00 WHSUR N SFAL DECOMP annulus. 4.

A RWO was performed in 1991 to replace 3.5" tubing with 4.5" tubing in preparation for a hydraulic fracture treatment. The well was shut in 1998 and returned to production in 2000 at 200 bopd, 80% WC, 1500 GOR; additional water influx seems to have occurred during the 2 year shut in period. There is a history of both intermediate casing hanger leakage and tubing hanger seal leakage. The outer annulus was downsqueezed with gelled diesel with cell flake additives 8/04. The well currently is shut in with TxlA communication and secured by a tubing tail plug. / Proiect: The scope of work includes a chemical cut of the tubing above the packer. the existing tubing will be cut and pulled, 9 5/8" packoff replaced, and 4.5" premium thread L-80 tubing rerun. The completion will consist of 4-1/2" L-80 premium thread tubing, in a stacked packer configuration, and no GLMs. Area Review ¿ There are no wells within 14 mile radius of Z-18. The cement job on the 5-Yz" liner went smoothly and was logged in November, 1989. Enclosed is a copy of the CBL log showing cement isolation between the 9-5/8" casing shoe at 13,459' md and the top perforation at 13,720' md. ___ Pre-RWO 1. Check wellhead lock down screws. (Unable to check wellhead seals due to remedial plastic packing) 2. Remove PXN plug from tubing tail and drift for chemical cut and FasDrill. 3. Set FasDrill plug in tubing tail just below packer (~13,167'ftd). 4. Chemical Cut 4Yz" tubing above packer (~13,13l' md). ~ 5. Circulate well clean with seawater and freeze protect with diesel. 6.

I. Supervisor Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Z Pad .Fr. idav, JanuarY. 19,.2_001: 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. .Spmmaw: I witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13.9% failure rate. 21 wellhouse inspections conducted.

Grimaldi i~-!~-~ Petroleum Inspector Wednesday. 1/9191: I performed a RIG/BOPE inspection on Doyon #16 working on Z-18 for BPX. The rig was in very good shape and the only problem I could find was that the gas detector for the rig floor was indicating a malfunction. The toolpusher was aware of this and explained to me that he had another sensor enroute and would install it as soon as it arrived. Their last BOP test was on 1/3/91. In summary: Doyon I6 is a very good looking and well maintained rig and appears to be in good shape for drilling. Note: Gas detectors were fully operational on Jan. 13, 1991 as per telecon with Jim Willingham, Doyon toolpusher. 02-00lA (Rev. 6/89) 20/ll/MEMO1.PM3 BP EXPLORATION BP Exploration (Alaska) Inc. 900 East Benson Boulevard P.O.
