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. !f you require any additionai information, please contact me or my alternate, Anna Dube, at 659-5102.

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 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: dudng 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, Onefailure, 2;4% 34 Wellhouse inspections, no problems.

I. 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 AOGC. C 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. Weilhouse inspections were conducted on the 21 wells tested with no exceptions noted. Summarv: I witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13.9% failure rate. 2t wellhouse inspections conducted.

As the attached AOGCC BOPE test report shows the test lasted 3 hours with two failures. Very minor leaks were detected on the manual kill line valve and the #10 valve on the choke manifold. Both valves will be repaired after casing is run (aprox. 3days) and cemented. The test went well with good test procedures being employed by the Nabors crews. The rig was clean and all related equipment appeared to be in good working order. The location was spacious and well organized.

Alaska hared ervices rilling RECEIVED MAY 05 1998 To: Blair Wondzell, AOGCC From: Jim Smilh, SSD Program Chanqes, Well Z-38 Date: May 5, 1998 Attached is a summary of the proposed program changes necessary for well Z-38 in Prudhoe Bay. Inability to prevent hole deterioration (sloughing Kingak) has forced us to plan abandonment of the existing hole in favor of redrilling the entire intermediate section to place the intermediate casing fully across the Kingak.

Lloyd Operations Drilling Engineer, Nabors Rig 18E Permit #98-60, Z-38 The present status of the Z-38 well is that the 7" casing has become stuck with the casing shoe at 10978'. Circulation is not possible due to packed off annulus. TD of the 8-1/2" hole interval is 11605'. The originally permitted 7" casing setting depth was to have been 11556' MD. This casing was cemented in place with a single stage cement job consisting of 237 sacks of Class G + 30% silica flour. The plug was bumped with 3000 psi. No shallow hydrocarbon potential was identified with the intermediate logging program, therefore a two stage cementing job was not required. The plan forward is to drill a 6" wellbore from 10978' to permitted TD of 16925' and run 4-1/2" liner from TD to 10828' MD. This will be cemented with 678 sacks of Class G cement.

Diverter, BOPE and mud fluid system schematics will be provided when determining rig (rig will be in the current fleet of north slope rigs and the schematics should therefore be on file with AOGCC). The Kuparuk interval will be drilled under the assumption that it is at the abnormal pore pressure of 10.4 ppg EMW pore pressure. Maximum anticipated bottom hole pressure is 3657 psi at 6764'TVDss. Maximum anticipated surface pressure assuming gas in entire annulus (0.1 ppg) is 2982 psi. Hazards · Ugnu may be slightly overpressure due to water disposal at GC-2 which is ,-,10 miles to the east. Estimated mud weight requirement is 9.3 - 9.5 ppg. · Hydrates in the surface interval are anticipated to require mud weights in the range of 10.2-10.5 ppg · One 80' fault is present within the planned wellbore (reservoir) projection. This fault will be discussed within the well plan and measures will be taken to control lost circulation or other problems associated with drilling across the fault. · Based on offset well data, there are known accumulations of frozen gas hydrates within the 200' - 2300' interval. _. The Kuparuk interval is potentially overpressured due to gas injection in the Kuparuk Operating Unit. Recent well data suggests that a pore pressure of 0.54 psi/ft (,-,10.4 ppg EMW) is possible. _. Low reservoir pressure and lost circulation due to Iow pore pressure within the reservoir interval. Disposal Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal.

Anchorage PROPOSED DRILLING PROGRAM WELL: Z-38 Drilling Operations: (All depths are approximate) The conductor hole will be pre-drilled and the 20" conductor set and cemented before the rig's arrival and while the camp is set up. Move in, rig up. Accept rig for operations. Nipple up diverter and function test same. The well will be drilled as a horizontal "sinusoidal" profile through the reservoir interval. The 12-1/4" hole section will be directionally drilled from 800'md and with multiple "nudge" intervals in the surface section. 9-5/8" 40# casing will be set at ,--22° and cemented to surface with two stage cementing equipment. Install blowout prevention equipment consisting of 5,000 psi W.P. pipe rams, blind rams, and 5,000psi annular preventer. Test B©P's. Maximum anticipated bottom hole pressure is 3658 psi (10.4 ppg EMW) at 6765' TVD. Maximum possible surface pressure is 2982 psi based on a gas column to surface from 6765' TVD. Formation leak-off tests will be performed 20' below the 9-5/8" and 7" casing shoes. The primary drilling in the 8-1/2" interval is a tangent to 7" setting depth. The 7" will be set with a angle of ,-,50° tangent 11636' MD. In the event shallow hydrocarbons are encountered while drilling the intermediate interval, a platform express logging suite along with RFT's and Side Wall Cores will be run. 7", 26# L-80 casing will be run with a 2 stage cement job planned to cover 100' above the casing shoe and also to cover shallow hydrocarbon intervals. A 6" well bore with a sinusoidal profile will be drilled to tpa two reservoir targets on opposite sides of a bisecting fault. The maximum angle will be 98° through the reservoir section, dropping back to 86.5° then building to 97° at the TD of 16925' MD (8826' TVDss). Platform express will be DPC conveyed. Clean out hole. Run and cement 4-1/2" liner. Drill pipe convey the perforating guns and run 3-1/2" completion string. The well is planned to be tested by the PEs after the drilling rig is moved off of the well.

Borax pass #1 depth offset = 24 feet. Borax pass #2 depth offset = 29 feet. 2. Ran spinner, temperature, and pressure sonde only to gather dynamic injection data during CNL passses. Pressure data was suppressed - inconsistent, spikey. 3. Descended to 16018 ft RiD initially. The only difficulty was encountered at GLM #7 at 3258'. Had to pump to gee tool centralized to pass. 4. All pumping was down the backside. Pass #1: Total pumped = 267 bbls KCL water and 135 bbls Borax. Pass #2: Total pumped = 325 bbls KCL water and 135 bbls Borax. Pass #3: Total pumped = 355 bbls KCL water and 135 bbls Borax. 5. The neutron count rates are lower on the baseline pass than on the Borax passes in upper portion of logging interval. This may be due to the early arrival of Borax on the Baseline pass. 6. Ail perforations are open.
