Abstract

Basinwide overpressured compartments have been observed in the Anadarko and other basins. Results are presented on a mechano-chemical model of this phenomenon that illustrates how the imposed pattern of sedimentary features and faulting can produce such a three-dimensionally isolated compartment.

The model is based on the solution of equations describing pressure solution, stresses, conservation of pore fluid solutes, and the evolution of pore fluid pressure. The model accounts only for quartz chemistry; fluid over-pressuring is solely through thermal expansion of the fluid and compaction.
