Induced AVO Anomalies From Pore Pressure Effects

AVO anomalies are normally associated to changes in the rock’s compressibility and<br>density, which is caused by changes in lithology and bearing rock fluids once the sedimentary<br>sucession is under hydrostatic pressure regime. Frequently, however, AVO signatures can be<br>quite ambiguous causing the need for well/seismic calibration using rock properties<br>and reflectivity modeling.
