Volumetric flowrate of the fluid phase across the well-reservoir contact


In most popular practical case of a 3-phase fluid model this will be:

Oil sandface flowrate

LaTeX Math Inline
bodyq_o

Gas sandface flowrate

LaTeX Math Inline
bodyq_g

Water sandface flowrate

LaTeX Math Inline
bodyq_w

Total sandface flowrate

LaTeX Math Inline
bodyq_t



In case of Volatile Oil Reservoir the connection with surface flowrates and mass flowrates will be:
