n: the maximum flow rate that a well could theoretically deliver with zero pressure at the face of the reservoir.

n: Actual mean value of rate of throughput through the pump.

n: a gas measurement device that consists of a mutiple-ported Pitot tube installed inside a pipe through which gas is flowing;it is installed perpendicular to the flow of gas. The length of the annubar is equal to the diameter of the pipe in which it is installed. An annubar senses the difference between total flowing pressure and static pressure;gas volume is calculated from this difference. See Pitot tube.

a gas flow rate measurement device using Pitot tubes. Common in pipelines.

n: the rate at which mud is travelling in the annular space of a drilling well.

n: The linear velocity of a fluid passing through an annular space. The term critical annular velocity is often used to describe the flow rate or velocity at which entrained solids will be efficiently transported by the annular fluid. If the fluid velocity f

the velocity of fluids flowing in the annulus. Important in clean-up and displacement processes.

n: a plant that contains instruments for the measurement and control of temperatures, pressures, flow rates, and properties of resulting products and thereby makes necessary corrections in the plant operating conditions so as to maintain specification products. Such a plant contains shutdown and other automatic devices for minimising damage in the absence of operating personnel.

n: a device that regulates various factors (such as flow rate, pressure, or temperature) of a system without supervision or operation by personnel. See instrumentation.

an isotope tracer in a bead with the same density of the flowing fluid that is used to track fluid flow rates and therefore fluid entry and exit points along the wellbore.

a quick opening, low pressure valve, common on large openings through which solids will move, that allows high flow rate when open.
