Summary
This chapter describes the basic mechanisms that give rise to subsurface excess fluid pore pressure. These mechanisms include rapid deposition where the fluid cannot escape as the sediments are deposited, giving rise to excess pore pressure. This is known as disequilibrium compaction. Other mechanism are also described, including chemical diagenesis, kerogen maturation, aquathermal pressuring, and hydrocarbon buoyancy effects.
