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 is related to surface flowrates of water
as:
q_t = B_w \, q_W |
where
| water surface flowrates | |
| formation volume factors between separator and sandface pressure/temperature conditions |
