Oil and gas reservoir with a gas cap. Gas production from these reservoirs may be restricted in order to preserve the gas cap energy and ultimate recovery.

n pi: total pressure at a depth underwater, expressed as multiples of normal atmospheric pressure.

n: A colloidal, viscosity-building clay used principally in salt-water muds.

a colloidal, viscosity building clay used in water based muds. They generate viscosity due to the mechanical interference of their straw shaped bodies.

n: A kind of baculate clay, sometimes called salt-resisting clay or brinish clay because it is easy to slake in the brine and it is high yield.

n: a plant that contains instruments for the measurement and control of temperatures, pressures, flow rates, and properties of resulting products and thereby makes necessary corrections in the plant operating conditions so as to maintain specification products. Such a plant contains shutdown and other automatic devices for minimising damage in the absence of operating personnel.

n: the average of all the instantaneous values of current or voltage in one-half a cycle of AC electricity;equal to 0.636 times the maximum value.

n: voltage induced in the armature of a motor by the magnetic field in which it is turning. Also called counter emf. See electromotive force.

an operation or transaction that results in movement of gas in a direction opposite of the normal flow direction in a pipeline.

n: an option right reserved by the granting company of a farmout to convert an overriding royalty to a working interest once the conditions for such back-in have been met. Compare election at casing point.
