Total sandface flowrate at injecting well or injecting wells:


Water InjectorGas Injector
(1) q^{\downarrow}_{tW} = B_w \, q^{\downarrow}_W
(2) q^{\downarrow}_{tG} = B_g \, q^{\downarrow}_G

where

q^{\downarrow}_W, \, q^{\downarrow}_G

water, gas surface flowrates

B_w, \, B_g

formation volume factors between separator and sandface pressure/temperature conditions
