Petrophysics and seismic wave technology: Applications in exploration, formation evaluation, and reservoir characterization

A new method for predicting the spatial variation in rock and fluid properties is presented along with laboratory results and a case study. Various models of porosity, permeability, pore-fluid and lithology were created to predict the corresponding P- and S- wave velocities and acoustic impedances. The best fit between synthetic seismic and sonic models would indicate the most probable reservoir model. The method could be useful in Reservoir Characterization, Formation Evaluation, and Seismic Exploration.
