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:
| Property | Symbol | Meaning |
|---|---|---|
| Oil production rate | ||
| Water production rate | ||
| Water injection rate | ||
| Gas injection rate |
The surface flowrates are also used to calculate the total sandface flowrate at downhole conditions.
