Volumetric flowrate of dead oil measured at separator of mostly degasified oil normally measured at SPE Standard Conditions (STP).
Usually produced from subsurface oil phase and gas phase.
It usually requires additional processing before taking commercial form of the crude oilCrude 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
The oil surface flowrate relates to Surface Liquid production rateIt relates to Liquid production rate at surface as:
| LaTeX Math Block |
|---|
|
q_O = (1-Y_W) \cdot q_L |
The oil surface flowrate relates to Total sandface flowrate as:
| LaTeX Math Block |
|---|
|
q_O = \frac{1-Y_W}{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_Lt |
It simplifies for the Black Oil model (
) to:
| LaTeX Math Block |
|---|
|
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 |
