Flow Rate

Definition - What does Flow Rate mean?

Flow rate can be defined as the speed or rapidness of a fluid or gas that flows through a channel or a vessel. This rate is a means of measuring the speed or velocity of liquid or gas that is meant to flow from a particular channel, pipe or a vessel. By determining how much mass or volume of gas or liquid passes per unit time, scientists can determine how deep the wells are to be dug or appraised in order to reach the reservoir.

Petropedia explains Flow Rate

The volumetric flow rate can be calculated as:

Q = v • A


v = Flow velocity

A = cross-sectional vector area/surface

The flow rate of oil and gas holds a very important role in the upstream sector of the petroleum industry.

The field production phase of the well test, in which a flow test is conducted to gather the data from an underground source of oil and natural gas, determines the production range of a well and whether it can be used for production or not. Therefore, tests are carried out at an oil field after it has been dug. The tests conducted over these fields help engineers to analyze the health of the well and its further requirements.
