n: a measure of the smallest increment of change in the pulse output of a flowmeter as it relates to the actual volume being measured.

n: the unit weight of a fluid, e.g., pounds per gallon.

The mass per volume density of a fluid.

n: in fluid dynamics, the state of a fluid in motion is determined by the type of fluid (e.g., Newtonian, plastic, pseudoplastic, dilatant);properties of the fluid such as viscosity and density;geometry of the system;the velocity. Thus, under a given set of conditions and fluid properties, the fluid flow can be described as plug flow, laminar (called also Newtonian, streamline, parallel, or viscous) flow, or turbulent flow.

n: the state of fluid dynamics of a fluid in motion is determined by the type of fluid (e.g, newtonian,plastic pseudoplastic, dilatant),the properties of the fluid such as viscosity and density, the geometry of the system and the velocity,thus under a given

the distance outward from the wellbore to the leading edge of the lost fluids. Varies with the permeability of the zone.

n: the erratic impact of a pump plunger against a fluid when the pump is operating with a partial vacuum in the cylinder, with gas trapped in the cylinder, or with the well pump off.

or rod pound – a beam lift term where the pump is filled with gas from pump-off or too fast of an operating speed (rod speed).

a measurement in the well of the pressure vs. depth. Useful for spotting liquid levels, leaks, fluid entries, etc.

n: the amount of the pore volume of a reservoir rock that is filled by water, oil, or gas and measured in routine core analysis.

the fractional or percent amount of pore space which a specific fluid occupies.

n: the reciprocal of viscosity. The measure of rate with which a fluid is continuously deformed by a shearing stress;ease of flowing.

n: a kind of highboy clean-up system for entire fluid ，equipped with vibrosieve，dust remover，sand remover ，mud remover and centrifuge
