a rheological model used to describe flow in some fluids. Bingham fluids have a linear shear stress, shear-rate behavior after an initial shear-stress boundary has been crossed. Plastic viscosity or PV is the slope of the line. Yield Point is the threshol

back pressure valve.

hydrocarbon pore volume.

n: 1. a gas whose molecules are infinitely small and exert no force on each other. 2. a gas that obeys Boyles law and Joules law. Also called a perfect gas.

a theoretical gas that perfectly obeys PV=RT/m, where V is the specific volume, T is the absolute temperature, R is the universal gas constant, and m is the molecular weight.

n: the equation of the state of an ideal gas, showing a close approximation to real gases at sufficiently high temperature and low pressures: PV=RT where- P = pressure R = gas constant T = temperature V = volume per mole of gas.

n: (PVT) trade name for a type of pit-level indicator. See pitlevel indicator.

n: (PV) the total volume of pore space in a reservoir formation.

n: (PVT) an examination of reservoir fluid in a laboratory under various pressures, volumes, and temperatures to determine the characteristics and behavior of the fluid.

abbr: pore volume.
