Box 196612 Anchorage, Alaska 99519-6( (907) 561-5111 - RE: Year End 1993 Endicott Oil Pool - Waterflood Surveillance Report Dear Mr. Johnston: STAT TECH; 'SLE -- Attached is the annual Endicott Waterflood Surveillance Report. This report covers the status of the Endicott waterflood program from the initiation of injection in February 1988 through December 1993. In addition, field surveillance and material balance information is provided from field start-up in October 1987 through December 1993. As in the past, BP Exploration extends an offer to brief the AOGCC to illustrate the present status and future waterflood plans. Please advise Mr. Mark Weggeland at 564-5351 concerning a convenient time for the meeting and if there are any other questions. S ncerely, _ D. E.

G=MlAAi0` Anchk,e ENDICOTT OIL POOL WATERFLOOD SURVEILLANCE REPORT DECEMBER 31 1993 P_roiect Status Summ This report covers the period from the start of water injection on February 29, 1988 through December 31, 1993 for the Endicott Oil Pool. During the report period, water injection occurred in twenty-two wells including 1-51N-20 which was drilled in 1993. 4-02/Q-28 was injecting until April and then was worked over and made into a producer in October. It will no longer be a swing well. 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 236.2 MMSTB of black oil and condensate, 6.4 MMSTB of NGLs, 403.6 BSCF of gas, and 90.4 MMB of water. Cumulative water injection into Endicott through December 1993 is 157.85 MMB sea water and 86.97 MMB produced water for a total of 244.8 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, 1993, reservoir voidage had exceeded gas and water injection by 94.16 MMRB. Injection 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 31, 1993 are shown. Exhibit 5 provides graphs of the injection rates, injectivity index, and wellhead pressure versus time for twenty- one water injection wells. 4-44/M-44 has no data available to plot because it remains shut in. Below is a detailed activity summary for several injection wells. A CTU cement squeeze was completed on the well drilled in March, 1993, 1- 51 N-20, and the well was recompleted in the MPI 313/3C sands. The well was initially completed as a Zone 3B and 3C water injector with the plan to pre - produce the well for 3 years. We have re-evaluated the strategy for the well and found no additional recovery benefits by pre -producing it. We added perfs and put it on permanent injection December 13, 1993. A CTU cement squeeze was completed on well 2-70/U-15, and the well was recompleted in the MPI 36/3C sands. The well was put back on injection in December. A rig workover was completed on well 4-02/0-28 in October so that the well could produce from SDI 3C1 sands. It is permanently on production. A rig workover was completed on well 3-45/M-39 in October to allow installation of an isolation packer tailpipe between the 2B and 3A subzones to help facilitate injection into the SDI 36/3A sequences. A rig workover was completed on well 2-34/P-14 in October to repair a leaking packer and to shut off gas from zone 1 A. The well was put back on injection. The SDI 2A interval in well 3-41/K-39 was reperforated February 28th. A tubing leak was discovered in March and the well has remained on injection via a variance from the AOGCC. The well will be worked over in 1994. The SDI 3C2 interval in well 4-40/P-43 received 25' of added perforations in January to evaluate if additional perforations need to be added to 3C1. This evaluation is still in progress. Well 1-37/P-24 was converted from MPI zone 2B injection to MPI zone 3A production in June. The well was returned to zone 2B injection in November, as seawater was again available. The well will remain a permanent injector. Well 4-08/P-27 was converted to a SDI zone 2A/2B water injector May 4, 1993. Well 4-44/M-44 remains shut in as it has no future utility as an injector due to poor pay. Well 2-64/U-10 remains shut in as a possible side-track candidate Water Iniection Performan 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. Commingled Water Inie tc ion To maximize sea water injection during winter months, commingled water injection started in October 1990. We have been able to continue commingled injection with no scale or operation problems. Waterflood Plan Reservoir pressure, gas and water movement will continue to be closely monitored. Changing needs will be met through new well drilling and converting producers to injectors. QECEivEc T aia;ka Uii & Gas Consi cmmissio Anchcr< ,= During 1993, two 3B/3C gas injection wells were drilled, both located on the MPI. Gas injection into the 3B/3C provides a means to better balance voidage and reservoir pressure in these sequences. This work will bring the Endicott injection well total to twenty-one and will improve sweep efficiency and increase our capacity to match voidage in these sub -zones. The waterflood surveillance program will be used to evaluate reservoir performance and determine the need for additional waterflood development wells.
