All wireline work will be done through a 5000 psi WP BOP/Lubricator, tested to 1.2 times the maximum expected surface pressure. The SSSV will be installed at the conclusion of the perforating and clean-up operation. The well is currently injecting source water. Seawater will be in the wellbore during perforating operations. These perforations are in the Victor waterflood zone. The reservoir pressure at the perforation depths is approximately 3710 psi. Proposed Perforation Interval' 11877' - 11954' Ref: BHCS 12/25/76.

ND tree. NU BOPE & test to a maximum of 2100 ps.i in order to minimize the shear stress on the tubing hanger support pins. (The BOPE will be re-tested after the 5-1/2" tubing has been pulled.) SA3/12a.2 ARCO A;aska, Inc. Date: June 2, 1988 Internal Correspm. ,ce File code: Subject: MGEVQY G~NERATION I WELLHEADS, MAXIMUM BOB TEST PRESSURE~ TUBING HANGER DESIGN CHANGES From/Location: D. C. Sims/AT0 1482 Telephone: X 4119 To/Location: F i ] e The unique design of the McEvoy' Gen I Unihead tubing hanger landing mecha- nism results in a reduced maximum BOP test pressure when a blanking plug is installed in the tubing hanger and pressure is applied above. The tubing hanger lands on four (4), 1.75" OD support pins in the tubinghead. The pins have a maximum shear strength of 100 KSI when new. Assuming a safety factor in shear of 2.0, the maximum allowable shear stress for each support pin is 50 KSI. An example calculation of maximum allowable BOP test pressure with a blanking plug installed is given below. Note that the maximum test pressure will vary with tubing string weight. Buoyed Tubing String Weight : 90,000 lbs. (4000' of 7" 26# in seawater) Tubinghead Profile ID-- 13.6 in. Max BOP Test Pressure = [4((50,000 lb./in2)(~r (1.75 in.)2/4)) - 90~000 lb.~ ( ¢r (13.6 in. )2/4) Max BOP Test Pressure = 2700 psi Due to this limitation, it is recommended that future workovers** of McEvoy Gert I wells include a modification of the tubing hanger landing mechanism that will eliminate the use of the tubing hanger support pins. Instead, a tubing hanger support bushing will be designed to land in the profile below the tubinghead and provide a landing shoulder for the tubing hanger. In cases where a casing string is already landed in the profile below the tubinghead, a smaller support bushing will be designed to land on the casing pack-off and provide a landing shoulder for the tubing hanger. In each case, the tubing hanger will have to be modified slightly to land on the support bushing rather than the support pins. Specifications for the tubing hanger support bushing and the modifications to the tubing hanger are available from Cameron/McEvoy. All machine work can be done in Anchorage, however, the 4130 steel necessary to machine the support bushing will likely have to be ordered. Questions 'or comments should be directed to Pete Thompson, McEvoy (562-2332} or Tom Taylor, McEvoy-Houston (713-939-2053). ** DS 1-~thru 1-6, DS2-2 thru 2-~, DS 4-1 thru 4-6, PWDW 1-1, PWDW2-1. , _.....~. _1'1 ngineer ' ~ ~ iZL.~ DCS:hf(DCS/35) xc: Workover Engineers £~n~ E.

Skaalure AOGCC CONTACT: Mike Mendor REASON: Injection Well 4-6 Annular Communication Per Rule 7 Requirement of Area Injection Order No. 4 DISCUSSION: Informed AOGCC that PWI injector 4-6 has a tubing leak and probable packer leak as diagnosed by temperature logging & pressure testing conducted on 7/31/87. AOGCC not notified earlier because of weekend. AOGCC had previously been notified of a potential annular communication problem on this well and that diagnostic work would be undertaken. Verbal approval was received at that time to continue injection operations until diagnostics could be completed. Informed AOGCC that well 4-6 was currently loaded with water and freeze protected, and would remain shut-in until a workover could be conducted. Mentioned that we currently had no plans to kill the well, but would continue to monitor the tubing & casing pressures to verify static wellbore conditions. AOGCC RESPONSE: Approved of steps taken to shut-in & secure well. Requested that Sundry Notice be filed to formally document the well's current condition and our plans for repairing the well.

Upon firing the FFP remained zero; however, the turbine meter rate surged to 3600 BOPD. The rate declined rapidly and was 2850 BOPD eleven minutes later when the well was SI. The second gun (a dual select-fire) was positioned to perforate the interval 12148-12158' M.D. SITP was 810 psig. The well was opened m~ 3/4" choke and was flowing at 0 FTP nine minutes later when the gun was fired. FFP rose to 25 psig, but the turbine meter failed and no rate response was available. The gun was repositioned to perforate the inte~wal 12133-12142' M.D. with the well flowing. Seven minutes after the initial perforation, the second perforations were made. The FTP rose in~ediately to ].50 psig. ~e well was SI two minutes later to allow repair of the turbine meter prior to cleanup flow. A piece of rubber was removed from the turbine meter and the well was opened on 3/4" choke. Initial FTP was 125 psig and initial rate was 5200 BOPD. In 25 minutes the FTP was 90 psig and the rate had declined to 4100 BOPD. Shortly thereafter, the FTP and rate began increasing. Fifty minutes into the flow, calcium chloride water and gas surfaced. FTP was 200 psig and the rate was ± 6000 BOPD. The turbine meter was bypassed and the clemmp flow continued. The well was flmved for m~ additional 1.5 hours until consistent production samples indicated the presence of no water. Total flow time was 2 hours and twenty minutes. Final FTP was 660 psig with a wellhead temperature of 42°F. ~ring this flow 535 barrels of fluid was recovered of which 242 bbls. was diesel, 73 barrels was calcium chloride water, and the remaining 220 barrels was reservoir fluid. D.S. #4-6 Perforation and Cleanup Record Page 2 A Fluid Density Log was run indicating the water at 12200' M.D. with a transi- tion zone to 100% oil at 12034' M.D. The third g~ (a dual select-fire) was positioned to perforate the interval 12117-12127' M.D. SITP was 1350 psig. The well was opened 3/4" d~oke and the FTP was 825 psig when the gunwas fired five minutes later. The g~ was reposi- tioned (with the well flowing)-to perforate the interval 12000-12007' M.D. The FTP was 660 psig when the second perforations were made and remained at 660 psig until the well was SI five minutes later. The fourth gun was positioned to perforate the interval 12095-12111' M.D. SITP was 1290 psig. The well was opened on 3/4" choke and FTP was 810 psig ~en the gun was fired. Pressure increased gradually and FTP was 975 psig five minutes later when the well was SI. The fifth gm~ was positioned to perforate the interval 12059-12082' M.D. SITP was 1320 psig. The Well was opened on 3/4" choke and FTP was 1020 psig five minutes when the gun was fired. The FTP was 1070 psig five minutes later when the well was SI. The sixth gun was positioned to perforate the interval 12039- 12059' M.D. SITPwas 1300 psig. The well was opened on 3/4" choke and FTP was 1075 psig when the gun was fired five minutes later. The pressure increased slightly in five minutes to 1090 psig and the well was SI. The final gun (a dual select-fire) was positioned to perforate the interval 11986-11993' M.D. SITP was 1290 psig. The well was opened on 3/4" choke and FTPwas 1110 psig five minutes laterwhen the gunwas fired. With the well flowing, the gun was repositioned to perforate the inte~al 11964-11972' M.D. FTPwas 1110 when the gun was fired. Five minutes later the well was SI. Final FTP was 1090 psig. An Amerada pressure bomb was used to determine the 8800'ss static pressure, 4378 psig. The well was flowed for 1 hour thirty minutes on 1/2" choke at ~n average 3947 BOPD resulting in 247 barrels of oil production. ]~e initial I~P was 1230 psig but had increased to 1340 psig just prior to SI With a wellhead temperature of 35°F. The Amerada showed a maximum drawdo~m (just prior to SI) of 82 psi, resulting in an approximate PI of 48.1 STB/psi. BHT was 190°F m~d fina~ SITP was 1480 psig. The total estimated volumes of oil and gas produced during perforating operations were 720 bbls. of oil and 540 MCF gas. 7/13/77 STAT~ OF A.LASIO~ North Alaska District Fmgineering TRANSMITTAL To' -- From' 9-8-77 Date' Well Name' J.

Atlantic Richfield Company proposes to perforate selected intervals within the Sadlerochit interval. All perforated intervals will be reported, on subsequent report. A 5000 psi WP wireline lubricator, tested to working pressure, will be utilized with all wireline work. All perforations will be made with hollow carrier type guns at 4 shots per foot. Well will be flowed to a surge tank to recover load fluids and any produced well fluids. All recovered liquids will be retained in the surge tank, then trucked to the oily waste disposal facilities for disposal. Any produced gas will be vented to the atmosphere during perforating operations. The down hole safety valve will be installed and tested upon conclusion of job. Estimated start date- May 16, 1977 16.

This 13-3/8" casing was landed at 2191' with 3 strings of external mounted sensors to monitor the freezeback process in the permafrost in February 1972. To study the freezeback influence of drilling mud in an open hole annulus, the shoe was cemented back to a depth of 1580'. A second stage job was per- formed through DV tool at 486'. The cement top was determined to be 400' based on a CBL. The permafrost base is at 1812'. Atlantic Richfield Company asked that this well be permitted as an exception to Title ll, Alaska Administrative Code, Section 22.540, Convervation Order No. 98-B, Rule 3(c). This exception was discussed on October 22 by John Miller of the Department of'Oil and Gas, and M. L. Waggoner, for C. R. Knowles, District Drilling Engineer, Atlantic Richfield Company. Atlantic Richfield Company proposes to directionally drill this well to 12,850'MD, 9085'TVD to produce the Sadlerochit zone. Dual Induction Laterolog~, Self Potential, Sonic, Gamma Ray, Density, Caliper and Com- pensated Neutron Logs will be run from TD to the shoe of the 9-5/8" casing (8220'TVD). A 13-5/8" 5000 psi Hydril, two 13-5/8" 5000 psi pipe rams and one blind ram will be used on the 13-3/8" and 9-5/8" casing. The BOP equipment will .be pressure tested weekly and operationally tested each trip. A non-freezing fluid will be left in all uncemented annuli within the permafrost interval. A single 5½" tubing string, packer, and appropriate subsurface safety equipment will be run in a weighted calcium chloride solution. The tubing will be displaced to the top of the packer with diesel.
