Summary:
Pore pressure estimation from seismic data is an important issue in exploration studies for prospect detection and drilling planning. The target of this paper is to present a strategy based on statistical techniques to predict pore pressure from seismic attributes. The proposed statistical approach to pore pressure prediction is based on factor analysis method and it is compared to classical deterministic models based on physical equations which link velocities to pressure. We tested the methodology on laboratory measurements and applied it to a real case study in North Africa.
