Volumetric flowrate of the dry gas measured at separator
Usually produced from subsurface gas phase and oil phase
For volatile oil fluid model the oil surface flowrate is related to oil sandface flowrate and gas sandface flowrate as:
q_O =(1-R_v \, R_s)^{-1} \left( \frac{q_o}{B_o} +\frac{R_v \, q_g}{B_g} \right) |
where
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:
q_O = \frac{q_o}{B_o} |
