Abstract

3D seismic inversion in integration with petrophysical properties has been qualitatively and quantitatively used in reservoir characterization of Oligocene Limestone reservoir in D18 area which lies in the southern part of Bombay High-DCS of Mumbai Offshore Block, Western Offshore Basin of India. Hydrocarbon accumulations have been established from three different levels of Oligocene Limestone reservoir in a number of wells while a few wells are dry. The aim of study was to define the limits of these pays and to separate out the tight carbonate zones to avoid dry hole drilling. Seismic inversion was carried out over PSTM seismic data enhanced for higher resolution using
