Flowrate of a specific fluid component(s) or pseudo-component(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:
Property | Symbol | Meaning |
---|---|---|
Oil production rate | q^{\uparrow}_O | Surface flowrate of total production of oil from all produced fluid phases measured at SPE Standard Conditions (STP). |
q^{\uparrow}_G | Surface flowrate of total production of gas from all produced fluid phases measured at SPE Standard Conditions (STP). | |
Water production rate | q^{\uparrow}_W | Surface flowrate of total production of water from all produced fluid phases measured at SPE Standard Conditions (STP). |
q^{\uparrow}_L | ||
Water injection rate | q^{\downarrow}_{WI} | |
Gas injection rate | q^{\downarrow}_{GI} |
The surface flowrates are also used to calculate the total sandface flowrate at downhole conditions.
In case of Volatile Oil Reservoir the connection with Sandface flowrates and mass flowrates will be:
