Publishable final report on Contract No JOF3-CT97-0036. / /The prediction and detection of abnormal formation pressure is fundamental to hydrocarbon exploration activities. Experience has shown that, with good seismic data, a rough estimation of formation pressure can be obtained. This project followed an integrated approach that combined the standard prediction technique from velocity analysis with a priori geological information, basin modelling and inversion while drilling, wave form (seismic) analysis relating amplitude information (Q) to fluid pressure, and well log calibration. Laboratory data were used to determine velocity -porosity transforms and rock physics models, based on laboratory and well log data. The methods developed were integrated by means of a prototype software for pore pressure prediction based on seismic modelling and inversion and was tested with field data from North Sea Viking Graben wells.
