Produced flowrate of live oil across the well-reservoir contact with the volumes measured at the sandface temperature and pressure conditions.
For MBO fluid model the oil sandface flowrate q_o is related to surface flowrates of crude oil q_O and natural gas q_G as (see derivation):
(1) | q_o = \frac{B_o \cdot (q_O - R_v \, q_G)}{1- R_v \, R_s} |
where
B_o | oil formation volume factor between separator and sandface pressure/temperature conditions |
R_v | Vaporized oil ratio at sandface pressure/temperature conditions |
It simplifies for the Black Oil model to:
(2) | q_o = B_o \, q_O |
