Volumetric flowrate of the dry gas measured at separator
Usually produced from subsurface gas phase and oil phase
For volatile oil fluid model the gas sandface the oil surface flowrate g is related to oil sandface flowrate is related to surface flowrates of crude oil O and natural gas sandface flowrate G as:
