A common type of situation where overpressure may occur is in a buried river channel filled with coarse sand that is sealed on all sides by impermeable shales.
Because overpressured sediments tend to exhibit better porosity than would be predicted from their depth, they often make attractive hydrocarbon reservoirs and are therefore of important economic interest.
