bodyB_o, B_g

oil formation volume factor between separator and sandface pressure/temperature conditions

LaTeX Math Inline
bodyR_v

Vaporized Oil Ratio at sandface pressure/temperature conditions


It relates to Surface Liquid production rateThe oil surface flowrate

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_t


It simplifies for the Black Oil model (
