Joint P and P-SV Inversion

Robert R. Stewart

ABSTRACT

Linear equations relate small changes in rock properties across an interface to seismic reflectivity (Aki and Richards, 1980). These equations for P-wave and P-SV wave reflectivity can be inverted exactly or in a least-squares sense to provide estimates of relative changes in density, P-wave velocity and SV-wave velocity. By using two observations (P and P-SV reflectivity), this inversion promises better rock property estimates.
