Seismic data is combined with well log data to generate a two-dimensional geopressure prediction display; this permits deviated and horizontal well planning plus lithology detection. Shale fraction analysis, compaction trend, and seismic velocity may be automatically or interactively generated on a computer...http://www.google.fr/patents/US5343440?utm_source=gb-gplus-shareBrevet US5343440 - Geopressure analysis system
