A Sag add perforation opportunity has been identified. The top of Sag_ is located at 9398'md in this well, above the production packer. This program requests to add cement to the annulus above the packer to become the primary barrier to the reservoir. This sundry requests approval for a total of -700'md of cement in the IA and -500' of cement above the Top of Sag. This is to prevent IA repressurization from potential cement channels through the Sag added perforations. Objective Add perforations to the Sag. Expected Start Date: April 1, 2018 Post-Job Evaluation This well is a gas lifted producer; an AA will not be applied for.

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: Chuck Scheve; SUBJECT: Petroleum Inspector DATE: April 24, 2001 Safety Valve Tests Prudhoe Bay Unit G Pad Tuesday, April 24, 200,1: I traveled to BPXs G Pad and witnessed the one-month retest of the safety valve systems. As the attached AOGCC Safety Valve System Test Report indicates I witnessed the testing of 16 wells and 32 components with no failures. The surface safety valve, on well G-03A closed rather slowly but passed its pressure test. The wing valve on wells G-16 and G-18A had very slow leaks but did ~notprohibit a valid test of the surface: safety valve:.::Well G-21:: wh.ich.?failed ~the pre~:ieus months ~test.~,d,uelo:~a frozen pilot :has the new style insulation box in place and functioned properly. Merv Liddelow performed the testing todaY; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection: of the Well:houses on this pad was performed during the SVS testing.with~ noproblems noted. Well G-14A which was:sh'ut inat this time and not tested~was found to have the new style insulation box on the pilot. This should fix the :Problems found on previous tests.

Merv Liddelow was the BPX representative in charge of testing and he performed the tests in a safe and proficient manner. Fifteen wells were tested with:nine failures witnessed. The pilots on wells G-02A, G-1 lA, 'G-14A and G- 21A failed to operate properly. The SSV's on wells G-01A, G-02A, G-03A, G-09 and G-13 failed to close or failed to hold D/P. Wells G-03 and G-09 were shut in pending repairs. Mr. Liddelow indicated to me that all other failures had been repaired and passed a retest within 24 hours. Fifteen well houses were inspected and slight crude oil leaks were noted on wells G-14 and G-16. Mr. Liddelow and his crew repaired these leaks immediately. The AOGCC test reports are attached for reference. SUMMARY.:.

Commission Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular DispoSal Records from July 25, 1995 through preSent time. We compared your list with Our records and are able to provide you with the following data: · Individual Annular Disposal Logs from the ssD database which coincide with the approved wells on your attached AOGCC Annular Log. The.SSD records are proVided to you in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: · Endicott wells 1~03/P-16, 1,65/N-25, 1-59/0-24 · EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30, L-21, K-38, NMP #1 & #2, K-05, K-02, H-07, K-25, K-37, E-17, F-21, K-30, K-34, K,21i, F-66, K-06, K-54, K-33, F,49i, K-18 · PBU Wells E-38, 18-34, 15-42, $-29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal. · The wells listed above in BOLD were not permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a Sundry Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells. Wells drilled between July 25, 1995 and June 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide you with a cumulative report from our database of records from July 25, 1995 through the present. FrOm those records, we show the following wells not listed on your report were used for annular dispOsal: L. {' ,, .Annular Disposal Letter .'. 12/14/98 ! · Endicott wells 1-23/O-15, 1-61/Q-20, 2-40/S-22 · Exploration well Sourdoueh #3 - ~' * o ~ , . · Milne Point wells F-06, ~05, ~-06, J-13, L-24 - ~s-~7~' PBUwells 18-30, 18-31, 14~,~-43, E-34, E-36, G-~A,~dS-33-~'~z Individu~ logs ~e provided to ~ou'.~' OSfo~ ~ these'S~' ~ogs' q fist' O~we~l · Finally, our records show that the B-24 outer annulus was left open (see attached correspondence) Thank you for the opportunity to provide clarity to these records.

As discussed this morning we propose setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid wastes. There areno other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter.

G0m,,nissi0n ^nch0ra¢0 Well Plan Summary G-21 Addition to Permit to Drill Request for Annular Injection Disposal' Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well G-21 for annular pumping. Request to AOGCC for Annular Pumping Approval for G-21: 1. Approval is requested for Annular Pumping into the G-21 9-5/8" x 7" casing annulus. . Aquifers in the Prudhoe Bay Field Western Operating Area (including K Pad) have been exempted from Class II injection activities by the AOGCC by Aquifer Exemption Order #1 as referenced in Area Injection Order #3. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 9-5/8" casing shoe will be set at 3533' MD (3520' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. , The burst rating (80%) for the 9-5/8" 40# NT-80 casing is 4,600 psig while the collapse rating (80%) of the 7" 26# L-80 casing is 4,328 psig. The break down pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 2845 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7" casing is filled with gas). MASP = 4328 psig - ((fluid density ppg - 1.9) X 0.052 X 9-5/8" Casing Shoe TVD) 5. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. 6. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.
