n: It be used to decrease the viscosity of the drilling fluid and convenient to separate.

n: a graduated rod, usually of metal, to which water-finding paper or paste can be applied. This paste or paper discolors on contact with water and thus affords a ready means of measuring the depth of water in a tank. Also called a waterfinding rule.

purposely injecting water below and/or into the reservoir to drive the oil towards the producing wellbore. This is a secondary recovery mechanism.

n: a pressure concussion caused by suddenly stopping the flow of liquids in a closed container.

a sharp, sometimes very high force and pressure load that is created when a valve is closed too rapidly in a flowing stream. The major force occurs behind the valve. Most common in a production well when sudden closure (slam closure) of a subsurface safet

n: pump used in waterflooding or in water disposal. In waterflooding, the pump injects water into a well drilled in one part of a reservoir to force oil to a production well. In water disposal, the pump injects water produced from a well into a reservoir for disposal.

n: a well into which water is pumped to dispose of the water or to recover oil in a waterflood.

a well used to inject water into a reservoir to maintain pressure or to drive hydrocarbons towards producing wells.

n: in the cooling system, a passageway inside the rim for circulating water.

n: see water distillation unit. water outlet n: the part of a gun barrel that provides an outlet for the water that has separated from an emulsion and that regulates the amount of water held in the gun barrel.
