Rock Physics Modelling and Seismic Inversion for Reservoir Characterisation

Abstract

Rock physics modelling is vital in various stages of exploration and production to comprehend the fluctuations in the seismic response to variations in the physical and fluid properties of rock. Rock physics explores the quantitative relationships of seismic, sonic or ultrasonic velocities to the petrophysical properties so as to predict beyond the existing data range facilitating the initial phase of seismic interpretation. This can be achieved through a forward or an inverse rock physics model, with the primary aim being linking the elastic properties of rocks to porosity, lithology etc. Therefore, rock physics is an integral part of reservoir characterisation, seismic reservoir monitoring and lithology discrimination.
