Volumetric flowrate of mostly degasified oil normally measured at separator or at processing plantSPE Standard Conditions (STP).
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 For MBO fluid @model the oil surface flowrate is related to oil sandface flowrate and gas sandface flowrate as as below (see derivation Derivation):
| LaTeX Math Block |
|---|
|
q_O =(1-R_v \, R_s)^{-1} \left( \frac{q_o}{B_o} +\frac{ R_v \, \frac{q_g}{B_g} \right) |
where
It relates to Surface Liquid production rate The oil surface flowrate relates to Surface Liquid production rateL and Total sandface flowrate as as:
| LaTeX Math Block |
|---|
|
q_O = (1-Y_W) \cdot q_L |
The oil surface flowrate relates to Total sandface flowrate as:

q_O = \frac{ |

}{B_w Y_W + \left[ (B_o - R_s B_g) + (B_g - R_v B_o) \, Y_G \right] \cdot (1-Y_W)} \cdot q_t |
It simplifies for the Black Oil model (
) to:

|
q_O = \frac{q_o}{B_o} =(1-Y_W) \cdot q_L = \frac{1-Y_W}{B_w Y_W + \left[ (B_o - R_s B_g) + B_g \, Y_G \right] \cdot (1-Y_W)} \cdot q_t |
