Volumetric flowrate of dead oil measured at separator.
Usually produced from subsurface oil phase and gas phase.
It usually requires additional processing before taking commercial form of the Crude Oil.
For volatile oil fluid model the oil surface flowrate q_O is related to oil sandface flowrate q_o and gas sandface flowrate q_g as (see derivation):
| (1) | q_O =(1-R_v \, R_s)^{-1} \left( \frac{q_o}{B_o} +\frac{R_v \, q_g}{B_g} \right) |
where
B_o, B_g | oil formation volume factor between separator and sandface pressure/temperature conditions |
R_v | Vaporized Oil Ratio at sandface pressure/temperature conditions |
It relates to Liquid production rate at surface as:
| (2) | q_O = (1-Y_w) \, q_L |
It simplifies for the Black Oil model to:
| (3) | q_O = \frac{q_o}{B_o} |
