n: a suspension of extremely fine particles in a liquid (such as colloids in a colloidal solution).

n: Subdivision of aggregates. Dispersion increases the specific surface of the particle, which results in an increase in viscosity and gel strength.

a mixture of a internal phase of solids, droplets or bubbles that stay relatively suspended in a continuous fluid.

breaker in small pill-form particles that stays with the polymer and helps break the mud cake.

n: the stay time of the hydrofluoric acid bottle inclinometer under the well

n: in pipeline construction, the means by which a river crossing stays on course. Frequently computerised, guidance systems may be based on information gathered by pendulums, which determine inclination;gyroprobes, which are sensitive to drift and bearing;and sonar. Lasers are also used to guide crossing.

n: The amount of time a liquid stays in a vessel. The retention time assures that equilibrium between the liquid and gas has been reached at separator pressure. The retention time in a separator is determined by dividing the liquid volume inside the vessel b

the time, based on the separator volume and shape and the fluid flow rate that produced fluids spend in a separator. It is based on the time needed to separate an emulsion.

n: diving in which a divers tissues are saturated with an inert gas to a point where no more of the gas can be absorbed by the body. Once a diver is saturated, decompression time remains the same whether he or she stays at the saturated depth for 24 hours or for several days. saturation point n: the point at which, at a certain temperature and pressure, no more solid material will dissolve in a liquid.
