Abstract
A method of predicting pore pressures at a proposed drilling location using Interval Transit Times derived from seismic data and Interval Transit Times from a calibrated normal geopressure trend. Seismic Interval Transit Times derived pore pressures and actual pore pressures derived from logs in a drilled well at an offset location are used to correlate graphically or analytically the seismic Interval Transit Times to normal geopressure interval transit times from a proposed drilling location to be used in the prediction of pore pressures at the proposed location.
