Y_G={\rm GOR}=Y_G=\frac{q_G}{q_O}


The simplest way to model the GOR in a given well is the GOR Fractional Flow @model:

GORY_G = Y_G {\rm GOR}= R_s + \frac{M_{rg}}{M_{ro}}  \cdot \frac{B_o}{B_g}

which provides a good estimate when the drawdown is much higher than delta pressure from gravity and capillary effects.
