ANNUAL RESERVOIR SURVEILLANCE REPORT
BADAMI OIL POOL
January 2004 – December 2004
1. Introduction
As required by Rule 9 of the Badami Oil Pool Area Injection Order, dated August 26, 1998,
this report provides a summary of the enhanced oil recovery operations at Badami.
The field was granted a suspension of production (SOP) by the Department of Natural
Resources in May of 2003. The field has been shut -in with the facilities in warm shutdown
mode since August of 2003. The SOP period allows for the evaluation of options for future
utilization of the existing infrastructure.
2. Summary of Reservoir Management and Enhanced Recovery
There has been no injection or production of fluids from the Badami reservoir in the period
covering this surveillance report. Charts of life -of-field oil production history and gas
disposition history are presented in Figures 1 and 2.
In January, 2004, diagnostics confirmed tubing by inner annulus communication in wells B1 -25
and B1 -28. Well service equipment was mobilized to Badami in August 2004 to secure the
wells. In B1 -25, an obstruction -- possibly collapsed tubing -- prevented access below about
4500’. A rig will be mobilized in April 2005 (via ice road) to secure this well. B1 -28 was
secured with an inflatable bridge plug, and the well will continued to be monitored.
3. Voidage Balance
There has been no injection or production of fluids from the Badami reservoir in the period
covered by this surveillance report. Therefore, cumulative voidage through December 31, 2004
remains negative 563,956 reservoir barrels.
4. Reservoir Pressure Monitoring
No bottom hole reservoir pressure surveys were taken at Badami during the report period. A
campaign to gather static reservoir pressures is planned for early in 2005. Wellhead pressures
are monitored daily for well integrity and safety purposes, however extrapolating these
pressures to bottomhole conditions is highly uncertain and inaccurate, and only measured
bottomhole pressures will be included in this report.
5. Production Logging
No production logging was performed during the report period on wells completed in the
Badami reservoir.
6. Special Monitoring
No special monitoring activities were performed during the report period.
7. Evaluation of Well Testing and Allocation
No wells have been tested during the report period.
8. Future Development Plans
BP is planning on obtaining static bottomhole pressures from existing Badami wells early in
2005. Based on this new data and ongoing study, BP will evaluate future plans of Badami
which could include restart of the field and separately, possible redevelopment through the
application of new well design or depletion technologies.
Monitoring of well integrity and surveillance activity on the Class 1 disposal well, B1 -01, will
continue as required.
9. Review of Annual Plan of Operations and Development
The field was granted a 5th POD which is a Suspension of Production (SOP) by the
Department of Natural Resources in May of 2003, which expires June 30, 2005. BP pla ns to
submit a new POD to DNR by June 1, 2005 which will outline any change in plan.
