Integrating 3D & 4D rock physics inversion data

The uplift in identification and prediction of hydrocarbon sands when using Rock Physics Inversion over Chi angle and Extended Elastic Impedance approaches is presented for a producing asset in Equatorial Guinea, West Africa. Deep water clastic reservoirs with rapid rates of production decline (`30% per year) require continuous phases of infill drilling to fully and effectively deplete the resource. Identification of remaining unswept potential in the fields requires the use of both 3D and 4D seismic data. The 3D data is required for the identification of sedimentary architecture of the reservoir bodies.
