Pore Pressure Assisted Earth Model Building

Abstract

This abstract presents the concept and examples of using pore pressure to assist in earth model building. In shale dominated clastic lithology environments a rock physics model relating velocity and pore pressure can be calibrated and used to convert velocity to pore pressure properties. The cross validation between velocity and overpressure, which follows the geology, can be used to better understand the model, help build an initial velocity model, and allow for the selection of tomography solutions with more confidence.
