Total produced or injected flowrate of water across the well-reservoir contact with the volumes measured at the sandface temperature and pressure conditions.
For the volatile oil fluid model the total sandface flowrate is related to surface flowrates of water as:
| (1) | q_t = B_w \, q_W |
where
q_W | water, oil, gas surface flowrates |
B_w | formation volume factors between separator and sandface pressure/temperature conditions |
