Abstract

Rock Physics Modelling acts as a bridge between elastic properties (P-wave velocity, S-wave velocity, density, impedance, Vp/Vs ratio) and petrophysical parameters (Volume of clay, Porosity, Water saturation). Rock Physics Models can be used to interpret observed sonic velocities in terms of reservoir parameters or even to predict beyond the available data range to study certain what-if conditions like change in facies or fluid. Over the years, Rock Physics Modelling has become an important tool in reservoir geophysics and an integral part of quantitative seismic interpretation.
