O-32 MUDSTONE COMPACTION AND ITS INFLUENCE ON OVERPRESSURE GENERATION IN THE NORTH SEA – A 3D CASE STUDY H. SYNOFZIK 1 S. HANSEN 2 and T. HANTSCHEL 1 1 Integrated Exploration Systems Bastionstrasse 11-19 52428 Juelich Germany 2 Norsk Hydro Summary Mudstones are one of the least permeable lithologies in most sedimentary sequences. Therefore mudstones can operate as seals leading to abnormal overpressures. It will be shown with respect to a 3D study in the North Sea that overpressure can be predicted by using basin modeling techniques. A compaction model for mudstones (Yang and Aplin 1995) that depends strongly on
