34. 56 - Cameroon). - Abnormal pressures associated with diapirs. 34) : palaeopressure due to uplifting previously deep-lying formations to shallower depths (A), confinement of pierced layers (B), isolated "rafts" on the top of the diapir (C). Because the overburden pressure transmitted to such isolated formations is omnidirectional, significant overpressure will develop within them (salt domes), pressure transfer from the undercompacted clays to the pierced reservoirs (D), osmotic effects due to raised salinity in the water of formations close to the salt dome (E).

A reduction in clay porosity is accompanied by an increase in bulk density. Measurements of clay porosity and density form the basis of the study of compaction. To summarize, normal clay compaction is the result of an overall balance between the following variables : - clay permeability, - sedimentation and burial rate, - drainage efficiency.

Geochemical fossils Fig. 27. - Hydrocarbon generation as a function of temperature and depth (modified from Tissot & Welte, 1978, and Kartsev, 1971). As compaction proceeds and less water is expelled, decomposing organic matter would tend to cause the water to become saturated in gas and eventually produce free gas. If this gas is unable to escape it causes abnormal pressure (HEDBERG, 1974). Pressure anomalies and undercompaction due simply to the overburden effect will be magnified if gaseous hydrocarbons are generated at the same time.
