When a [[Normal hydrostatic pressure#Fluid pressure|fluid pressure]] is higher than estimated from the [[Normal hydrostatic pressure gradients|normal hydrostatic fluid gradient]] for a given depth, it is called overpressure. For this situation to occur, the fluid must first be trapped within a rock unit (pressure compartment).

For this situation to occur, the fluid must first be trapped within a rock unit (pressure compartment).

Overpressure can be caused by [[uplift]], increased [[heat]], [[compaction]], [[Hydrocarbon generation|generation of hydrocarbons]], or a combination of these factors.
