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 surface flowrate q_O is related to gas sandface flowrate q_g and oil sandface flowrate q_o as:
| (1) | q_G =(1-R_v \, R_s)^{-1} \left( \frac{q_g}{B_g} +\frac{R_s \, q_o}{B_o} \right) |
where
q_o, \, q_g | |
B_o, B_g | oil formation volume factor between separator and sandface pressure/temperature conditions |
R_s | Solution GOR at sandface pressure/temperature conditions |
It simplifies for the Black Oil model to:
| (2) | q_G = \frac{q_g}{B_g} |
