The case study based on the inversion study of an area, situated in Cauvery basin, east cost of India. The objective of this area is to delineate and identification of reservoir sand through seismic inversion. We will discuss here the deterministic and the geostatistical method of seismic inversion and how their results are used for reservoir characterization. The major challenge in reservoir property modeling of Oil industries is to integrate the vertical resolution of petrophysical data with seismic data for lateral as well as vertical extension. In deterministic inversion reservoir properties are directly related with the amplitude of seismic data, but in geo-statistical inversion reservoir properties of wells are populated into the inter well space, simulated with 3D seismic data. Pre-stack deterministic and post-stack geostatistical inversion was carried out for characterization of reservoir properties. Probable litho facies and impedance volumes generated from geostatistical inversion captured distinctively the heterogeneity and small scale variations in the inter-well region that help us to delineate and identification of reservoirs.
