A significant step-change in the prediction of pore pressures has been developed by UT Austin whereby not only the vertical stress is considered to contribute, but consideration of the lateral stress components and the shear stress are included in combination with seismic velocities. This approach has been systematically verified and validated by UT Austin, and has provided valuable insight into the sub-surface pore pressure and stress conditions for exploration wells - the pre-drill results have been very well matched by the well measurements. This provides a new era of pore pressure prediction in combination with geomechanics to enable safe and efficient drilling.
