n: 1. a permeable body of rock capable of yielding groundwater to wells and springs. 2. the part of a water drive reservoir that contains the water.

n: (1) water bearing strata. (2) aqueous section in water controlled reservoir.

a water containing formation that may or may not be directly connected to the hydrocarbon bearing zone. A connected aquifer may or may not offer pressure support to the pay.

n: see water drive.

n: a combination of two or more natural energies that work together in a reservoir to force fluids into a wellbore. Possible combinations include gas-cap and water drive, solution gas and water drive, and gas-cap drive and gravity drainage.

n: see water drive.

n: the force exerted by a body of fluid at rest. It increases directly with the density and the depth of the fluid and is expressed in pounds per square inch or kilopascals. The hydrostatic pressure of fresh water is 0.433 pounds per square inch per foot (9. 792 kilopascals per metre) of depth. In drilling. the term refers to the pressure exerted by the drilling fluid in the wellbore. In a water drive field. the term refers to the pressure that may furnish the primary energy for production.

n: the load exerted by a column of fluid at rest.hydrostatic pressure increases uniformly with the density and depth of the fluid.

pressure created by a column of fluid that expresses uniform pressure in all dirrectins at a specific depth and fluid composition above the measurement point.

n: the method of producing a gas reservoir that is not associated with a water drive. Gas is removed and reservoir pressure declines until all the recoverable gas has been expelled.

a method of producing a reservoir when water drive is not available. Also a condition that exists when the gas pressure is drawn down before the oil is recovered.
