ABSTRACT

We estimate overpressure in the Columbus Basin, Trinidad W.I. using PS-waves. Shallow gas in this region reduces both seismic quality and velocity for P-waves, therefore, we use a modified Eaton's approach for pressure prediction using PS-wave moveout velocities, and we verify our findings with well data.
