ABSTRACT:
A method designed to combine both pseudo compressional interval velocity and pseudo shear interval velocity from seismic data for predicting fluid type and porosity in oil and gas exploration. The first step is the generation of ψS, pseudo shear reflectivity data, and P, pseudo compressional reflectivity data from the seismic data. The second step of the method is to produce scaled pseudo shear reflectivity ψVs and scaled pseudo compressional reflectivity ψVp from both the ψS and P data and then combine and re-project the ψVs and the ψVp data. The compression and shear reflectivity data are inverted, scaled to pseudo-velocity and then calibrated to well control. The resulting ψVp and ψVs volumes produce fluid volume and porosity volume. The fluid and porosity volumes can be stored in an electronic storage medium for analysis to distinguish between commercial and non-commercial gas accumulations prior to drilling.
