Volumetric flowrate of dead oil measured at separator
Usually produced from subsurface oil phase and gas phase
For volatile oil fluid model the oil surface flowrate is related to oil sandface flowrate and gas sandface flowrate as (see derivation):
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 relates to Liquid production rate at surface as:
q_O = (1-Y_w) \, q_L |
It simplifies for the Black Oil model to:
q_O = \frac{q_o}{B_o} |
