[PDF] From Feasibility to Reservoir Characterization: A fully integrated 4D seismic approach for reservoir management. A case study in the Western African offshore
Author: Cyrille Reiser, Didier Lecerf
SEG - 1 January 0001
The development and management of deep-water fields requires material investments and must be supported by the best technology solutions and tools. In this paper, we highlight how the seismic data was used to support the reservoir monitoring of a producing field in the West Africa Offshore. We also discuss how a dedicated 4D seismic project helped in the understanding of fluid movements and fault behaviors in the field in the aim of
identifying business opportunities and driving decision making over our Area of Interest.
