1999 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 1999.
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 this past year
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 1999.
The Endicott Field is generally described as having three areas. The three areas are fault
blocks which are identified as the MPI (Main Production Island area), the SDI (Satellite
Drilling Island area), and the NFB (Niakuk Fault Block). Vertically there are six subzones
(3C, 3B, 3A, 2B, 2A, 1) which 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 subzone 3C gas cap in both the MPI and the SDI areas in 1993. Reservoir
studies subsequently identified the SDI 3C area as a primary EOR target and supported
the decision to halt immiscible gas injection in that subzone. As a result, SDI 3C gas
injector 1-15/P-25 has been shut-in since July 1998.
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.
2
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 mmscfpd.
In reality, the maximum sustainable MI rate achieved by the compressor has been closer to
20 mmscfpd, which can be handled by one well at a time. As a result, miscible gas
injection has primarily been alternated between NFB 3A injector 2-22/L-14 and SDI 3C
injector 4-04/T-26. Produced gas samples have been collected in all of the producers
offset from these injection wells to provide a baseline for use in MI breakthrough
monitoring.
Figure 1 shows a map of the field with current well statuses including the existing water
injectors, gas injectors and oil producers. Well service additions and changes from the last
report date include:
• 1-33B/L-24 Sidetracked MPI 2A producer (02/99)
• 3-49A/M-40 Converted from a producer to an injector (04/99)
• 1-67/T-20 Converted from a producer to an injector (05/99)
Table 1 summarizes total production, injection, and well count data for the entire pool
through December 1999. Table 2 details the reservoir balances by area and subzone
through December 1999. The NFB is included in with the MPI on Table 2 for simplicity.
Appendix 1 provides graphs of Production and Gas/Oil Ratio versus Time by area and
subzone.
Appendix 2 provides graphs of Cumulative Crude Production and Percent Original Oil in
Place (OOIP) Recovered versus Time by area and subzone.
Appendix 3 provides graphs of Cumulative Voidage and Reservoir Pressure versus Time
by area and subzone.

Appendix 4 provides graphs of the injection rates, injectivity index, and wellhead pressure
versus time for each of the active injectors.
Waterflood Tracer
The waterflood tracer program was started in 1988. A total of 19 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). 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.
Figure 2 is an Endicott well plat showing the dates and types of tracers injected and the
producing locations where the tracer has appeared.
Future Waterflood/EOR Plans
In 2000 there are no plans to trace additional water injectors. Forty wells will be monitored
for tracer, and fifteen wells will be monitored for sea water breakthrough. Samples of
produced gas will continue to be obtained in the production wells which offset the EOR
injection wells to monitor MI movement. The Endicott owners are working with Nuovo
Pignone, the company which designed the miscible gas compressor, to bring its
performance up to design standards.
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 through new well drilling, converting producers to injectors,
profile modification of existing injectors, and target injection rate control. Offtake will
continue to be optimized through new well drilling, remedial work on existing producers,
and production rate control.

1999 Pressure Monitoring Key Well Program
Introduction
A pressure monitoring key well program was submitted to and approved by the AOGCC in
Administrative Approval No. 202.5. 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 key wells were chosen to provide a real 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.
Seventeen wells were identified as key wells to track pressure variation within the five
major subzones in each of the two main producing areas of the reservoir. Changes have
been made through time as reservoir and well characteristics changed in order to provide
representative data. 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 seventeen 1998 Key Well
reservoir pressures.
1999 Pressure Monitoring Program
Table 4 summarizes the wells included in the Proposed 1999 Key Well Program. The
1999 program consisted of seventeen key wells. Table 5 summarizes the key well
pressure data gathered in 1999.
Appendix 5 lists, by subzone, 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 6 plots, by subzone and area, key well reservoir pressures along with all other
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.
5
2000 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. Although changes in
well service and configuration occasionally necessitate changes to the pressure monitoring
program in order to obtain representative data, BPX recommends no changes in the 2000
program.
Table 6 summarizes the 2000 Endicott key well pressure monitoring program proposal.
As in past years, the amount of static pressure data obtained annually will likely exceed the
seventeen wells included in the proposed 2000 Key Well Pressure Monitoring Program. At
the operators discretion, representative reservoir pressures gathered in other wells during
2000 might be substituted for the proposed key wells to minimize production impacts or for
operational necessity. As the field matures, we will be increasingly challenged with
managing this need for additional pressure data while minimizing the cost and associated
production impacts.

1999 GOC Monitoring Key Well Program
Introduction
A GOC (Gas - Oil Contact) Monitoring Key Well Program was submitted for the Endicott
Field in October 1988, one year after field start-up in accordance with AOGCC
Conservation Order 202, 9(c). 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 key well program for Endicott is based on the understanding of a limited ability to
monitor fieldwide 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 6 degree 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.
Key wells were designed to focus on the 3A and 2B subzones, the more massive high
quality sands where more regional GOC effects could be noted. Key wells to monitor gas
movement in the 2A (MPI), 36, and 3C are not practical due to the close proximity to gas
and complex stratigraphy (shaliness), respectively. In these cases, it is highly doubtful time
lapse logging would provide meaningful data with respect to regional GOC movements.
Six key wells were originally proposed and approved for GOC monitoring: 1-01/J-19,
1-09/J-18, 1-27/P-20, 1-29/M-25, 2-04/M-19, 3-01/N-29. Waivers from continued GOC
monitoring have been received for three of the key wells due to gas influx from maturing
reservoir depletion. Following are the wells no longer monitored:
• 1-09/J-19 : 3A gas under -run.
• 2-04/M-19 : 2B gas under -run.
• 3-01/N-29 : Completed as 3A & 2B producer after waterflood response.

Figure 4 is an Endicott well plot showing the six GOC Monitoring Program wells.
1999 GOC Monitoring Program
During 1999, a total of 12 cased - hole pulsed and compensated neutron logs (PNL / CNL)
were acquired, including the three key well surveys. These logs are routinely used for
reservoir surveillance and diagnosing well problems in order to develop reservoir
management plans and remedial interventions. Following is a list of the wells from which
neutron logs were acquired during 1999:

Table 7 details the history of pulsed neutron log observations in the six GOC key wells,
including the 1999 observations. Three of the six original key wells continue to provide
useful gas -oil contact movement information, as gathered through time lapsed cased hole
neutron logging. Note the use of the CNL is precluded in all wells except 1-27/P-20 due to
size restrictions of down -hole completion equipment employed at Endicott. The table also
identifies GOC movement and gas influx by under -running major shales within Subzones
3A and 2B.
2000 GOC Monitoring Program
The Endicott GOC Monitoring Key Well Program has been successful in establishing
baseline and repeat PNL / CNL surveys to monitor and document rates of gas cap
movement and gas under -runs in the six key wells. It appears that the gas cap itself has
not moved significantly since about 1995 in Subzone 2B & 3A in the MPI. In the Niakuk
Fault Block in well 1-01/J-19, Subzone 2B has been re -saturated with oil and has remained
so since 1996. Perforating this target will be evaluated in 2000.
I
BPX recommends that the 2000 GOC Key Well Program continue with the three remaining
key wells: 1-01/J-19, 1-27/P-20, 1-29/M-25. Production logging and down -hole mechanical
isolation of gas prone intervals has also provided a means to monitor gas influx. Together,
these tools constitute an effective means to monitor gas movement at Endicott.
