Alaska 99519-6612 &.. �� i_>, (907) 561-5111 RE: Year End 1990 Endicott Oil Pool - Waterflood Surveillance Report Dear Mr. Johnston: Attached is the annual Endicott Waterflood Surveillance Report. This report covers the status of the Phase 1 and the 313/3C subzones waterflood program from the initiation of injection in February 1988 through December 1990. In addition, field surveillance and material balance information is provided from field start-up in October 1987 through December 1990. BP Exploration recommends a briefing in March 1991 to illustrate the present status and future waterflood plans. Please advise Mr. H. L. Hellman at 564- 4785 concerning a convenient time for the meeting and if there are any other questions. Sin Xi «u B. J.

Coms�lss(°' ENDICOTT OIL POOL WATERFLOOD SURVEILLANCE REPORT DECEMBER 31, 1990 Proiect Status Summ This report covers the period from the start of water injection on February 29, 1988 through December 31, 1990 for the Endicott Oil Pool. During the report period water injection occurred in seventeen wells, fifteen previously reported wells and two new wells. Exhibit 1 shows a map of the field with the year- end well status including the existing water injectors, gas injectors, and oil producers. Cumulative Endicott production since start-up is 118.1 MMSTB of oil, 126.2 BSCF of gas, and 21.0 MMB of water. Cumulative water injection into Endicott through December 1990 is 64.5 MMB sea water and 16.9 MMB produced water for a total of 81.4 MMB as detailed in Exhibit 2. The cumulative injected and produced reservoir volumes since start-up are shown in Exhibit 3. As of December 31, 1990, reservoir voidage had exceeded gas and water injection by 57.53 MMRB. Iniection Well Performance An overview of waterflood performance is shown in Exhibit 4. Total injection volumes, the target injection rates, injectivity index and well start-up dates through December 30, 1990 are shown. Exhibit 5 provides graphs of the injection rates, injectivity index and wellhead pressure versus time for the seventeen water injection wells. Below is a detailed activity summary for several injection wells. Well 1-37/P-24 was converted from zone 2B injection to zone 3A production during November, 1990 and placed on production December 2, 1990. This well will be converted back to injection after freeze-up in the fall of 1991. After that, the utility of this well will alternate between 3A zone production during the summer and 2B zone injection during the winter. Well 1-37/P-24 will be used as an oil producer to drain an area of the 3A sub -zone where drilling an additional well could not be justified. Simulation studies calculated that using 1-37/P-24 for half the year would not affect recovery if injection is comparably increased in well 2-34/P-14. Water injection in well 1-69/V-19 commenced in November, 1990. This well was pre -produced for 3 months to clean up perforations in preparation for water injection. Normal injection rates have been 8-9 MBWPD at approximately 2100 psi wellhead pressure. Well 2-64/U-10 was drilled as a down dip water injector for zone 3C. Attempts to establish injection have been unsuccessful due to the low permeability of the sands. Stimulation options are under evaluation. Water injection in well 4-48/K-43 commenced in December, 1990. This well was pre -produced for 2 months to clean up perforations in preparation for water injection. Normal injection rates have been 11 MBWPD at approximately 2100 psi wellhead pressure. The MPI 3A water injector, well 2-44/R-12, is under evaluation for a rig workover to repair a parted connection in the 7" liner 4' above the 7" WD packer. Water Injection Performance Pressure surveys taken as part of the reservoir surveillance program continue to verify the restricted pressure communication across the mid -field fault system. The observed pressures in the SDI region continue to be lower than those observed in the MPI region. Implementation of water injection in the SDI area has mitigated the pressure decline in subzones 2A, 2B and 3A. Refer to Exhibit 6 for the bottomhole pressure data and voidage plots since field start-up. Summer Sea Water Quality To maximize sea water injection during the winter months, commingled water injection started in October 1990. Winter sea water injection is improved over 1989 with no scale or operation problems. Future Waterflood Plans There are seventeen water injectors in the field with injection capacity over 200 MB/D . This brings to completion the Phase 1 injection program for subzones 3A, 28, and 2A, as well as the subzones 3B and 3C waterflood. The waterflood surveillance program will be used to evaluate the reservoir performance and determine the need of Phase II Waterflood Development wells. 1�.i'd �11 FFR 2s��`'. Alas'ria Oil & a; Cnns.
