O-25 CHALLENGES OF POROSITY BASED PORE PRESSURE PREDICTION DR. R. E. SWARBRICK 1 GeoPOP University of Durham Department of Geological Sciences South Road Durham DH1 3LE UK Abstract Porosity is used as a rock property implicitly reflecting the degree of compaction of sediment. The porosity values may be derived from wireline response or a porosity attribute may be used directly for example velocity data derived from seismic. Where undercompaction occurs due to fluid retention and overpressure porosity is retained above the level referred to as “normal compaction”. Hence a methodology has been developed which can work well in low temperature
