Volumetric flowrate of the dry gas measured at separator
For volatile oil fluid model the gas sandface flowrate is related to surface flowrates of crude oil
and natural gas
as:
q_g = B_g \, ( q_G - R_s \, q_O) |
where
| crude oil and natural gas surface flowrates | |
| gas formation volume factor between separator and sandface pressure/temperature conditions | |
| Solution GOR at sandface pressure/temperature conditions |
It simplifies for gas reservoir with surface flow rate and gas formation volume factor
to:
q_g = q_G \cdot B_g |
