Figure F1. A. Overpressure (P*) results when sedimentation occurs more rapidly than fluids can be expelled by compaction. B. This is recorded by an "undercompacted" porosity profile. C. Overpressure is often interpreted from the undercompacted profile. A suite of models describes how overpressure is generated during rapid deposition (Bethke, 1986; Bredehoeft and Hanshaw, 1968; Gibson, 1958; Koppula and Morgenstern, 1982; Osborne and Swarbrick, 1997; Swarbrick and Osborne, 1996).
