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