Flowrate of a given specific fluid component(s) or pseudo-component measured at separator(s) measured at SPE Standard Conditions (STP).
Whenever is used the fluid component should for the fluid component / pseudo-component for which the surface flowrates is measured should be explicitly specified to avoid confusions For confusion, for example:

The surface flowrates are also used to calculate the total sandface flowrate at downhole conditions.
