Prediction of Resistivity Using P and S-wave Properties from Prestack Seismic Inversion

In this paper, we study the prediction of resistivity from seismic data, based on resistivity-velocity relationships calibrated from well logs. Previous efforts in this area have included predicting resistivity from seismic amplitude or seismic-derived P-wave velocity. Here we present the prediction of resistivity from both P and S wave properties (P-impedance and Poisson’s ratio), which can be derived from prestack seismic inversion. The results can be used for identification or upgrading prospects in a mature field where resistivity logs are abundant.
