We have investigated the value of isotropic seismic converted-wave (i.e., PS) data for reservoir parameter estimation using stochastic approaches based on a floating-grain rockphysics model. We first performed statistical analysis on a simple two-layer model built on actual borehole logs and compared the relative value of PS data versus amplitudevariation-with-offset (AVO) gradient data for estimating the floating-grain fraction. We found that PS data were significantly more informative thandoi:10.1190/segam2013-0305.1 fatcat:edvbfb3kbzfoxpvohqd5h2v7ve
