Volume of fluid which passes through wellbore per unit time:
m = \frac{d M}{ d t} |
| SI unit | Metric unit | Oilfield units |
|---|---|---|
| kg/s | kg/s | ft3/s |
Depending on context the flowrate can be measured at separator (and called Surface flowrates) or downhole (and called Sandface flowrates).
