Application of Anisotropy in Pore Pressure Prediction

B-37 APPLICATION OF ANISOTROPY IN PORE PRESSURE PREDICTION Summary The vertical component of the P-wave interval velocity or slowness is the main ingredient in pore pressure prediction and seismic data are the main source of acoustic velocity estimation. It is known that most sedimentary rocks especially well-consolidated shales display anisotropy characteristics and that conventional velocity analysis method cannot provide vertical velocity in the presence of anisotropy. In a companion paper our co-workers discuss estimation of vertical velocity in the presence of transverse isotropy. In this paper we present application of transverse isotropy (TI) in pore-pressure prediction. We present pertinent formula
