closing pressure at surface for a gas lift valve.

n pi: empirical values for the critical properties (such as temperature, pressure, and volume) of a chemical system made up of multiple components.

a magnetic gravity field expression that is measured at or transformed to the magnetic pole. Susceptibility values are converted to density values and expressed as a vertical integration.

adj: having the capability of changing apparent viscosity with a change in shear rate. Pseudoplastic fluids gain viscosity when subjected to a decrease in shear rate, and lose viscosity when the shear rate is increased. See shear

n: a kinds of non-Newtonian fluid, its character is that it flows when enforced by slim shear stress.



a complex non-Newtonian fluid without thixotrophy. Flow starts with pressure but apparent viscosity decreases instantaneously with increasing rate of shear.

surface opening pressure of the gas lift valve.

pressure safety valve.

n: a device used to measure the amount of water vapor, or relative humidity, of the air. See sling psychrometer.
