Date of Defense 2001-12-04 Availability unrestricted AbstractWest Delta Block 84 Field is located off the coast of Plaquemines Parish, Louisiana. The intent of this endeavor is to prove that the two of the reservoirs, the KE-1 and KF-1, form a single communicating reservoir, the KEKF-R1; that a waterflood into the KF-1 reservoir was ineffective; that oil reserves were bypassed; and that a portion of these bypassed oil reserves can be recovered without drilling new wells.
Comparisons between pre-seismic and post-seismic geological interpretations were studied, a thorough volumetric analysis was performed with a subsequent material balance calculations and a reservoir computer simulation was performed. Once a history match was made, prediction studies were performed for both remaining “primary” reserves and for secondary reserves recoverable through a new water-flood design and implementation.
There are many new insights on this reservoir as a result of this study. First, the KE-1 and the KF-1 reservoirs are indeed one communicating reservoir. The KF-1 waterflood was inefficient and resulted in bypassed oil pay. Bypassed oil may be recovered through several techniques. Based on prediction runs on BOAST, the best case scenario analyzed thus far without additional drilling is an additional 1,600,000 barrels of oil. This study indicates that a small amount of old technology, in the form of a resurrection of a waterflood and a small amount of new technology, in the form of the "Downhole Water Sink" (DWS) method will greatly increase the ultimate recovery of the “lost” reserves.
This study has provided sufficient evidence and documentation to justify the need for additional research and study of this reservoir. More detailed recovery strategies should be prepared, the DWS technology should be studied in more detail and a more detailed grid should be prepared for the reservoir.
