n: 1. a disklike plate of anhydrite, gypsum, limestone, or sulphur overlying most salt domes in the Gulf Coast region. 2. impermeable rock overlying an oil or gas reservoir that tends to prevent migration of oil or gas out of the reservoir.

n: a subsurface hydrocarbon trap created by faulting, in which an impermeable rock layer has moved opposite die reservoir bed or where impermeable gouge has sealed the fault and stopped fluid migration.

a formation that contains oil or gas that is held in place by a displaced, non permeable rock mass.

n: 1. a subsurface layer of rock containing steam or hot water that is trapped in the layer by overlying impermeable rock. 2. a subsurface layer of rock that is hot but contains little or no water. Geothermal reservoirs are a potential source of energy.

n: 1. a porous, permeable, irregularly shaped sedimentary deposit surrounded by impervious rock.2. a lenticular sedimentary bed that pinches out, or comes to an end, in all directions.

a permeable, often small sedimentary deposit bordered by impermeable rock.

n: see formation pressure.

n: The pressure of fluids within the pores of a reservoir, usually hydrostatic pressure, or the pressure exerted by a column of water from the formations depth to sea level. When impermeable rocks such as shales form as sediments are compacted, their pore f
