In the northwest Gulf of Mexico, an empirical relationship exists between subsurface pressure, bottom-hole temperature, and seismic velocity. The pressure, velocity, and temperature patterns are controlled by sedimentation and faulting. Hydrologic fluid pressures and resulting fluid flow can be predicted and mapped by making use of mud weights, seismic velocities, and bottom-hole temperatures. Pressure, velocity, and temperature data have been compiled into extensive computer databases. This has allowed us to manipulate the data for the preparation of regional hydrodynamic head, seismic interval velocity, and isotherm maps. The application of this pressure-velocity-temperature relationship has led to the detection of an underpressured reservoir in the Oligocene's clastic section of southwest Louisiana. The prediction of the sandy underpressured zone with interval velocity analysis provides a useful tool to explore seismically for the fluviodeltaic sands in this area.
