For volatile oil fluid model the oil surface flowrate flowrate
is related to oil sandface flowrate LaTeX Math Inline body q_O
and gas sandface flowrate LaTeX Math Inline body q_o is related to surface flowrates of crude oil
and natural gas LaTeX Math Inline body q_O LaTeX Math Inline body q_G
as:g
| LaTeX Math Block | ||||
|---|---|---|---|---|

q_oO = B_o(1-R_v \, R_s)^{-1} \left( \frac{q_O - _o}{B_o} +\frac{R_v \, q_G)_g}{B_g} \right) |
where
| crude oil and natural gas surface flowrates | ||||
| oil formation volume factor between separator and sandface pressure/temperature conditions | ||||
| Vaporized oil ratio at sandface pressure/temperature conditions |
It simplifies for the Black Oil model to:
