The Ravva 4D Seismic Study - A Multidisciplinary Approach for Identification of Bypassed Oil

A 4D seismic survey was carefully planned, executed and interpreted on the Ravva Field. The geoscience and 4D seismic studies have provided key information that defines fault compartments, position of the current OWC and reveals potential undrained areas in field. In this paper, we describe a multidisciplinary approach for the identification of potential areas of bypassed oil. We show examples of how geoscience and engineering disciplines work together and explain the 4D responses which have delineated the areas of the undrained hydrocarbons. The recent infill drilling results along with on-going dynamic reservoir surveillance programs are in line with the 4D interpretations. All these results are being used to up-date the reservoir model for optimal reservoir management and development.
