Volumetric flowrate of dry gas measured at separator
Usually produced from subsurface gas phase and oil phase
For volatile oil fluid model the gas surface flowrate is related to gas sandface flowrate and oil sandface flowrate as (see derivation):
q_G =(1-R_v \, R_s)^{-1} \left( \frac{q_g}{B_g} +\frac{R_s \, q_o}{B_o} \right) |
where
oil formation volume factor between separator and sandface pressure/temperature conditions | |
Solution GOR at sandface pressure/temperature conditions |
It simplifies for the Black Oil model to:
q_G = \frac{q_g}{B_g} |
