f Use of Pore Pressure Modeling to Constrain Seismic Velocities

Seismic low velocity anomalies may indicate overpressure when related to porosity anomalies due to undercompaction. However, other processes can generate overpressure without porosity anomalies such as lateral transfer. Geological pore pressure modeling can help to explain such situations. Examples will be shown with anomalously low velocities in anticlinal settings not observed in surrounding synclines.
