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 / pseudo-component for which the surface flowrates is measured should be explicitly specified to avoid confusion, for example:
