Endicott Shut-in well list Endicott Oil Field 2010 Waterflood Surveillance Program Introduction Conservation Order 202 Rule 12 approved a field wide waterflood project for the Endicott reservoir. The waterflood was to be implemented within two years of regular production and a waterflood plan submitted three months before actual water injection began. By letter, dated June 15, 1988, the plan to implement the field wide waterflood was approved and semi-annual pressure maintenance project reports stipulated. The Endicott Waterflood development was recognized as complete and fully operational by letter, dated January 11, 1991, and annual waterflood surveillance reporting was approved. This document constitutes the report for 2010. Project Status Summary Endicott Field production began in October 1987. From field start-up, produced gas has been reinjected back into the existing gas cap to provide pressure support. Water injection was initiated in February 1988, and a tertiary recovery process was initiated with the installation of a miscible injection compressor and commencement of miscible injection in March 1999. This report summarizes the cumulative effects of pressure maintenance since field start-up and details activities in 2010. The Endicott Field is generally described as having three areas. The three areas of the field are fault blocks identified as the MPI (Main Production Island), the SDI (Satellite Drilling Island), and the NFB (Niakuk Fault Block). Vertically there are six subzones (3C, 313, 3A, 213, 2A, 1) that are the general geological subdivisions within the Kekiktuk formation. Initially, produced gas was reinjected into the gas cap in the updip portion of MPI subzones 2A and 2B. Gas injection was extended into the MPI subzone 3A gas cap in May 1988 and into the MPI and the SDI subzone 3C gas cap in 1993. Reservoir studies subsequently identified the SDI 3C area as a primary EOR target and supported the decision to reduce immiscible gas injection in that subzone. In July 1998, SDI 3C gas injector 1-15/P-25 was shut-in. From July 1998 to June 2010, well 1-15/P-25 was returned to service on numerous occasions while wellwork was planned and executed on the primary gas injectors. In June 2010 well 1-15/P-25 failed an MIT -IA and was shut in for tubing by inner annulus communication. Non -rig attempts to restore integrity have failed 2 and well 1-15/P-25 is currently shut-in. Water injection is occurring in peripherally placed injectors in all subzones in all areas of the field with the exception of Zone 1, which is on primary depletion and Niakuk 2A which currently has no off -take. Endicott's EOR project began in March of 1999. The original EOR Phase I implementation plan consisted of 8 water -alternating -gas (WAG) injection wells, with two wells being on MI at any given time. This plan was based on an MI compressor design rate of 45 mmscfd. The average MI injection for 2010 was 4.4 mmscfd, with peak rates of 16.0 mmscfd. In 2010, miscible gas injection occurred in 1 well; SDI 3B/3C injector 1-67/T-20. Produced gas samples are routinely collected in all of the producers offset from the injection wells in order to monitor MI breakthrough. Figure 1 shows a map of the field with well status as of December 31, 2010 including the existing water injectors, gas injectors and oil producers. The well service changes taking place in 2010 were as follows: Well 3-43/P-36 was converted from a producer to an injector. Table 1 summarizes total production, injection, and well count (wells online during December 2010) for the entire pool through December 2010. Table 2 details the reservoir balances by area and subzone through December 2010. The Niakuk Fault Block (NFB) is included with the Main Production Island (MPI) on Table 2 for simplicity. Appendix 1 provides a graph of Production and Gas/Oil Ratio versus Time by area and subzone. Appendix 2 provides graphs of Cumulative Voidage versus Time by area and subzone. Appendix 6 lists the wells in the participating area that were shut in for all of 2010. 3 Infection Well Performance Table 3 provides an overview of the performance of each of the pressure maintenance injectors. Included in this exhibit are the start-up dates and cumulative injection volumes. Appendix 3 provides graphs of the injection rates, injectivity index, and wellhead pressure versus time for each injector. Waterflood Tracer The waterflood tracer program was started in 1988. A total of 24 water injectors have been traced: 3 in 1988, 8 in 1989, 6 in 1991, and 3 in 1996 (well 2-44/R-12 was traced with two different tracers), 2 in 2005, 1 in 2007, 3 in 2008 (well 3-35/L-36 was traced with four different tracers), and 1 in 2009 (well 3-35/L-36). The program has been very successful in identifying the progress of the waterflood as depletion matures. Numerous interventions have been implemented on producers and injectors to improve ultimate recovery. Based on the maturity of the waterflood tracer program, the decision was made to discontinue sampling efforts on all producers except for those immediately offset to injectors 3-351-36, 3-41/K-39, and 3-45/M-39; in 2008. In 2010, with the completion of the LoSaITM Pilot, sampling on the wells offset to injectors 3-351-36, 3-41/K-39, and 3-45/M-39 was also discontinued. Figure 2 is an Endicott well plat showing the tracer data for the LoSaITM Pilot. It includes the dates and types of tracers injected and the producing locations where the tracer has appeared. For information on the waterflood tracer programs completed prior to 2010, reference the 2009 Endicott Surveillance Report. Reservoir pressure and gas and water movement will continue to be closely monitored through logging, mechanical isolations, and well testing. Changing pressure maintenance needs will continue to be met by evaluating new well drilling locations, converting producers to injectors, profile modification of existing injectors, and target injection rate control. Offtake will continue to be optimized by evaluating new well drilling locations, remedial work on existing producers, and production rate control. .19 r- Eider PA .so -W U-10 u -IQ ' NSN QQ k S", *YaE•Qt I I 5"4V--%1/SN-06 0- g T �JS�"iL73 IN -20 rt - Figure 1. 2010 Well Status — Endicott Field, Alaska Sag Delta North PA Duck Island Unit C -3a h.. � �W'— 'y [.x-39 39 �'�`0A34�13 A_2ry7.34 �;E 41 TgiO3 4N'fr37 �6 P-43 Kekiktuk Subzornes 3A 3C 2A IWO1 4.77 Nishak aril SAG SAG S 4.77 Map Scale - 1' = 4673 Feet BP Exploration, Alaska Inc * ** TABLE 1 ENDICOTT OIL POOL SUMMARY OF PERTINENT DATA (as of December 31, 2010) Water Injection Start-up: February 29, 1988 Miscible Gas Injection Start-up: March 24, 1999 Endicott Production since Field Start -Up: Black Oil and Condensate (MMSTB) 455.9 NGL's (MMSTB) 24.6 Gas (BSCF) 2608.9 Water (MMB) 1142.4 Endicott Injection since Field Start -Up: Gas (BSCF) 2304.9 Miscible Injectant (BSCF) 34.8 Water (MMB) 1523.0* Wells in Operation during the month of December 2010: Oil Producers 51 Gas Injectors 5 Water Injectors 20 Water -Alternating -Gas Injectors 1 Waste Water Disposal 0 ** Total 56 Water injection volumes do not include Cretaceous injection Cretaceous injector not shown in Figure 1 2 NOTE: Water injection volumes do not include Cretaceous injection NOTE: Voidage is calculated as Injected Volumes minus Produced Volumes _Ki_ MPI TOTAL 5.11 TABLE 2 1.90 133.62 10.78 1,121.21 ENDICOTT OIL POOL 592.68 18.46 2,072.83 RESERVOIR BALANCE FOR WATERFLOOD SANDS 1,474.00 0.00 3.58 Through 12/31/2010 728.06 0.00 2,205.64 (Values in MMRB) MPI & NIAK REGION by SUBZONE Produced Volume 3C 3B 3A 2B 2A Oil 28.89 43.35 31.24 84.72 165.64 Solution Gas 10.75 16.14 11.63 31.54 61.66 Free Gas 115.28 119.42 128.81 248.76 498.16 Water $073 73.14 76_87 215.57 193.81 Total 174.90 235.90 236.91 549.06 857.61 Inoected Volumes Gas 227.56 120.31 28.01 518.49 579.63 MI 0.41 1.49 1.68 0.00 0.00 Water 43.78 115.95 103.14 200.47 264.73 Total 271.74 237.75 132.83 718.95 844.36 Net Voidage Volumes Total 96.85 1.85 -104.08 169.90 -13.24 SDI REGION by SUBZONE Produced Volume 3C 3B 3A 213 2A Oil 61.78 19.13 33.63 93.43 47.94 Solution Gas 23.00 7.12 12.52 34.78 17.85 Free Gas 205.65 28.87 7.48 40.83 148.66 Water 140.53 4132 86.63 179.24 135.47 Total 407.96 89.32 127.74 313.50 332.07 I nieclffj Vlms Gas 94.68 6.25 0.00 0.00 0.00 MI 14.91 5.26 0.00 0.00 0.00 Water 137.67 102.71 79.84 388.24 132.16 Total 247.26 114.23 79.84 388.24 132.16 Net Voidage Volumes Total -160.71 24.91 -47.90 74.74 -199.91 FIELD TOTALS by SUBZONE 3C 3B 3A 2B 2A Produced Volume Oil 90.67 62.48 64.87 178.15 213.58 Solution Gas 33.75 23.26 24.15 66.32 79.50 Produced Gas 320.93 148.29 136.29 289.60 646.82 Water 171.26 114.45 163.50 394.81 329.28 Total 582.86 325.22 364.65 862.55 1,189.67 Injected Volumes Gas 322.24 126.56 28.01 518.49 579.63 MI 15.31 6.76 1.68 0.00 0.00 Water 181.45 218.66 182.98 588.71 396.89 Total 519.00 351.98 212.67 1,107.20 976.52 Net Voidaae Volumes Total -63.86 26.76 -151.99 244.64 -213.15 NOTE: Water injection volumes do not include Cretaceous injection NOTE: Voidage is calculated as Injected Volumes minus Produced Volumes _Ki_ MPI TOTAL 5.11 358.94 1.90 133.62 10.78 1,121.21 2.57 592.68 18.46 2,072.83 0.00 1,474.00 0.00 3.58 0.00 728.06 0.00 2,205.64 -18.46 132.81 K1 SDI TOTAL 0.54 256.45 0.20 95.46 0.37 431.86 0.10 583.28 1.00 1,271.59 0.00 100.93 0.00 20.17 0.00 840.63 0.00 961.73 -1.00 -309.86 1 FIELD TOTAL 5.65 615 2.10 229 11.14 1,553 2.66 1 176 19.46 3,344.42 0.00 1,575 0.00 24 0.00 1.569 0.00 3,167 -19.46 -177.05 Table 3 Endicott Oil Pool Injection Well Data Through 12/31/2010 MPI Reservoir Area Cumulative Cumulative Cumulative Water Gas MI Start -Up Well Name MMBW BSCFG BSCFG Date 1-05/0-20 534.1 May -88 1-23/0-15 89.2 Mar -95 1-37/P-24 33.5 Dec -87 1-41/0-23 74.5 Dec -95 2-06/J-22 664.7 Oct -87 2-12/Q-16 333.0 Apr -93 2-16/M-16 99.7 Mar -89 2-22/L-14 68.6 4.7 May -89 2-24/M-12 4.8 Mar -95 2-34/P-14 96.5 Nov -89 2-44/R-12 20.8 Mar -89 2-54/Q-12 101.8 Jan -92 2-64/U-10 13.8 Dec -90 2-70/U-15 22.4 0.6 Jul -89 5-01/SD-07 625.4 Oct -87 5-02/SD-10 76.6 Jan -88 SDI Reservoir Area Cumulative Cumulative Cumulative Water Gas MI Start -Up Well Name MMBW BSCFG BSCFG Date 1-15/P-25 147.7 Jun -93 1-43/P-26 176.6 Apr -89 1-51N-20 17.3 Apr -93 1-67/T-20 27.5 3.7 May -99 1-69N-19 24.5 Dec -90 3-01/N-29 +++ 10.6 Mar -09 3-07/N-28 47.6 Apr -89 3-17F/K-30 ++ 4.6 Feb -09 3-35/L-36 """ 7.0 Nov -07 3-37/L-35 45.0 Aug -98 3-41/K-39 156.3 Apr -89 3-43/P-36 // 0.0 May -94 3-45/M-39 77.0 Sep -88 3-47/Q-35 25.6 12.5 Mar -95 3-49A/M-40 35.2 0.2 Apr -99 4-02/Q-28 8.5 May -88 4-04/T-26 / 44.0 13.1 Mar -90 4-08/P-27 48.4 May -93 4-14/R-34 --- 38.1 Oct -89 4-40/P-43 7.1 Oct -92 4-48/K-43 + 20.0 Dec -90 Total 1523.0 2304.9 34.8 Note: Water injection volumes do not include Cretaceous injection.

This program supersedes the requirements of Conservation Order 202, Rule 6(c), and complies with Conservation Order 202, Rule 6(d). The pressure monitoring program's key wells were chosen to provide areal coverage of reservoir pressure in each of the major subzones in the two production areas of the reservoir. Historically, the Key Well Program has included at least two points of pressure measurement for each of the producing subzones, one from each MPI and SDI area, to ensure that a valid picture of reservoir pressure behavior can be drawn. Sixteen wells were identified as key wells to track pressure variation within the five major subzones (2A/2B/3A/3B/3C) in each of the two main producing areas of the reservoir. In order to provide representative data, changes have been made throughout time as both the reservoir and well characteristics have changed. Much more reservoir pressure data, other than the key well data, is gathered to address specific well and reservoir surveillance needs. Figure 3 is an Endicott well plot showing the location of the fifteen Key Well reservoir pressures and one Non -Key reservoir pressure for 2010. Due to no off -take occurring in Niakuk 2A there was no pressure monitoring proposed for Niakuk 2A. 2010 Pressure Monitoring Pro ram Table 4 summarizes the wells included in the proposed 2010 Key Well Program. Table 5 summarizes the key well pressure data gathered in 2010. Appendix 4 lists all current and former key wells with the reservoir pressures obtained since field start-up. These pressures are adjusted to a datum depth of 10,000 feet TVDSS, as is customary in our state pressure reporting. Appendix 5 plots, by subzone and area, key well reservoir pressures along with all other 10 reservoir pressure surveys. Generally speaking there is good agreement between the key well reservoir pressures and other pressure gathered around the field. There are a few exceptions where wells are in small pressure isolated regions. 2011 Pressure Monitoring Program The Endicott Key Well Pressure Monitoring Program has been successful in establishing and monitoring pressure trends within each of the major subzones. Changes in well service and configuration occasionally necessitate changes to the pressure monitoring program in order to obtain representative data. As in previous years BPX plans to combine the MPI 3B and MPI 3C into a single pressure monitoring region. Only one well is completed in the MPI 3B interval and historic pressure data indicated reservoir pressures in the two intervals share a similar performance. Table 6 summarizes the 2010 Endicott key well pressure monitoring program proposal consisting of fifteen wells. As in past years, the amount of static pressure data obtained annually will likely exceed the fifteen wells included in the proposed 2010 Key Well Pressure Monitoring Program. At the operator's discretion, representative reservoir pressures gathered in other wells during 2010 may be substituted for the proposed key wells to minimize production impacts or for operational necessity. 11 Eider PA r- 1 L� Figure 3. � t8 *S4342 i3 2 1d to W20 Sag Delta North PA Duck Island Unit 30 2010 Pressure Data — Endicott Field, Alaska KekiMuk Suwones 3A 3c 2A 1.95 Past Streams - 1.

At that time, BP Exploration sought, and received a waiver (Administrative Approval Order 202.5) from the State of Alaska, to initiate the key well program for Endicott on a subzone basis for each of the three distinct reservoir development areas of the field. Administrative Order No. 232.1 provided an exemption for key well GOC monitoring in Sections 1, 3, 7, 9, 10, and 35 of the field as being outside a real gas cap limits of the reservoir. The initial GOC Monitoring Key Well Program consisted of six wells: 1-01/J-19, 1-09/J-18, 1-27/P-20, 1-29/M-25, 2-04/M-19, 3-01/N-29. Conservation Order No. 462, rule 9 (b) revoked the Key Well Monitoring Program and allowed the operator to submit modifications to the Gas Oil Monitoring Program for Commission approval. The details of the 2010 GOC Monitoring Program as submitted by the operator are listed in the section below. The GOC monitoring program for Endicott is based on the understanding of a limited ability to monitor field -wide gas cap movement. A scarcity of wells and limited lateral offset from gas severely restricts the use of time lapse cased -hole logging as a viable tool to predict gas movements at Endicott. It is recognized that narrow hydrocarbon corridors caused by a relatively steep 60 structural dip combined with sands separated by thick laterally continuous shales promotes under -running as a common gas movement mechanism. In addition to the continuous shales that separate the reservoir into six vertically isolated subzones, major East-West trending fault offsets provide either lateral hydraulic isolation or partial pressure communication between the three main Endicott development areas. The more massive high quality sands of the 3A and 2B subzones are where more regional GOC effects are more easily noted. Monitoring region gas movement in the 2A subzone is more tenuous due to the close proximity to gas and likelihood of localized gas coning and under runs. Monitoring gas movement in the 313, and 3C subzones is not practical due to complex stratigraphy (shaliness). 16 2010 GOC Monitoring Program During 2010, two cased -hole neutron logs were acquired. These logs are routinely used for reservoir surveillance and diagnosing well problems in order to develop reservoir management plans and remedial interventions. The following are the wells from which the neutron logs were acquired during 2010: Well Location 2-2813/0-19 MPI 1-27/P-20 MPI In addition to the cased hole neutron logs run in 2010, a total of 4 production logs were acquired. These logs are routinely used to understand changes in zonal performance and consequently the need for remedial intervention. Following is a list of wells from which production logs were acquired during 2010. Well Location Well Location 1-27/P-20 MPI 3-03/J-33 SDI 3-27/M-33 SDI 4-38/K-34 SDI 2011 GOC Monitoring Program BPXA proposes a 2010 GOC Monitoring Program that consists of a notional five well program focusing on the 2A, 213, and 3A intervals and to a lesser extent the 3B and 3C intervals. The 2A, 213, and 3A intervals have the highest potential for monitoring depletion and improving recovery through effective reservoir management and the identification of potential infill drill locations. Production logging and down -hole mechanical isolation of gas prone intervals also provide a means to monitor gas influx. Together, these tools constitute an effective means to monitor gas movement at Endicott and will be a part of future GOC Monitoring Programs. 17 Appendix 1 Production Rate versus Time Plots BP ALASKA - ENDICOTT MPI Reaion - Zone 1 Production (Oil Rate, GOR, WC) 1x10' 1002 87 as 89 90 91 92 93 94 95 98 97 98 99 00 01 02 03 04 05 06 07 08 09 10 r(1-1) Cal Day Oil (bbi/d)x-(L1) GDR (cf/bbl) +-(R1) Wtr Cut % VS Time BP ALASKA - ENDICOTT RADI Omriinn - 7nno 90 Prnductinn /Oil Rate.
