Abstract

A methodology is developed to invert for time-lapse variations of reservoir pressure and saturation from repeated P-wave seismic data. Based on a simplified petroelastic correlation, two independent elastic parameters are obtained; one of which depends on pressure and the other on saturation. Forms for reflectivity and elastic impedance explicitly dependent on production effects are derived and tested on a reservoir model-based study. Following the inversion of multi-angle near, mid and far elastic impedance stacks from the baseline and repeat seismic dataset, reliable dynamic estimates of pore pressure and fluid bulk modulus are obtained.
