Total produced flowrate of live oil across the well-reservoir contact with the volumes measured at the sandface temperature and pressure conditions.
For the volatile oil fluid model the oil sandface flowrate q_o is related to surface flowrates of crude oil q_O and natural gas q_G as:
(1) | q_o = B_o \, (q_O - R_v \, q_G) |
where
q_O, \, q_G | crude oil and natural gas surface flowrates |
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 |
