f Towards integrated petrophysical and seismic modelling

The prediction of lithological and reservoir properties from seismic data requires a strong coupling between rock physics and seismic wave propagation. There is a wide range of rock properties which influence on seismic wave propagation. The most commonly considered parameters are porosity, type of pore fluid and matrix composition (e.g. sand/shale ratio). Less attention is paid to the seismic effects caused by the variability of the pore space properties (e.g. pore geometry), and the influence of immiscible pore fluids (i.e. the various pore fluids occupy different pore volumes). The latter effect should be carefully taken into account when applying seismic methods for monitoring fluid-fluid interfaces in hydrocarbon producing reservoirs.
