n: (W/C) water put into an empty string of pipe in a wellbore to prevent the pipe from being crushed by pressure in the annulus.

n: A volume of water placed in a tubing string prior to conducting a drillstem test or opening a well to flow. The water cushion is designed to reduce and control the pressure drawdown applied to the reservoir when the downhole valve or tester valve is opene

a level of water in a string to be used for flowback to generate an initial damping back pressure.

n: the percentage of water in fluid produced from a well. v: to locate the oilwater interface and use the location to measure the volumes of oil and water in a shore tank or ship compartment.

the amount of water in percent in a produced fluid stream.

n: the depth of free water in a container over and above the dip plate.

a well where produced water is injected back into a deep, usually depleted zone but one that is not connected to the producing pay zones.

n: equipment used mostly on offshore or desert locations to convert salt water to potable fresh water.

n: the reservoir drive mechanism in which oil is produced by the expansion of the underlying water and rock, which forces the oil into the well bore. In general, there are two types of water drive: bottom-water drive, in which the oil is totally underlain by water;and edgewater drive, in which only a portion of the oil is in contact with the water.

a reservoir drive mechanism where an aquifer provides pressure support and pushes towards the low pressure area around the well, driving the oil ahead of it.

n: an oilfield in which the primary reservoir drive mechanism is water.

n: the movement of water into a producing formation as production depletes the formation of oil and gas.

n: The measure used to seal the water layer in the drilling process or workover,for example,squeeze cement.
