Pore Pressure and Stress State

Published:

Abstract

Pore-pressure prediction from well-log and seismic data is critical in drilling operations and also is important in estimations of geomechanical parameters and stress-states from seismic data. It is well established that stresses in the subsurface have a direct impact on rock physics and, hence, on seismic amplitudes. Indeed, knowledge of effective-stress variations laterally and with depth markedly reduces interpretation uncertainty and helps separate intrinsiceffects from extrinsic influences of pore pressure and stress state on seismic rock properties. An approach to pore-pressure and vertical-effective-stress analyses is discussed in Chapter 2.
