Ratio of gas production rate to oil production rate
:
{\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:
GOR = Y_G = 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.
