Abstract
We propose an innovative approach to calculate pore pressure from seismic velocities using Biot-Gassmann theory and Skempton coefficient. The first synthetic tests on North Sea overpressured shales show reliable results which are close to the pore pressure estimated with conventional empirical Bowers formula. The new method is promising as it does not require any extensive calibration.
