For volatile oil fluid model the total sandface flowrate is related to surface flowrates of fluid components as:

|---|---|---|---|---|

q_t = q_w + q_o + q_g = B_w \, q_W + (B_o - R_s \, B_g) \, q_O + (B_g - R_v \, B_o) \, q_G |
where
| water, oil and gas sandface flowrates | ||||
| water, crude oiland natural gas surface flowrates | ||||
| formation volume factors between separator and sandface pressure/temperature conditions | ||||
| Solution GOR and Vaporized oil ratio at sandface pressure/temperature conditions |
It simplifies for the Black Oil model to:
