Flowrate of a given fluid component or pseudo-component measured at separator
Whenever is used the fluid component / pseudo-component for which the surface flowrates is measured should be explicitly specified to avoid confusion, for example:
Expression | Symbol | Meaning |
---|---|---|
Oil production rate | q_O | Surface flowrate of total production of oil from all produced fluid phases measured at SPE Standard Conditions (STP). |
q_G | Surface flowrate of total production of gas from all produced fluid phases measured at SPE Standard Conditions (STP). | |
Water production rate | q_W | Surface flowrate of total production of water from all produced fluid phases measured at SPE Standard Conditions (STP). |
q_L | ||
Water injection rate | q_{WI} | |
Gas injection rate | q_{GI} |
The surface flowrates are also used to calculate the total sandface flowrate at downhole conditions.
