Total sandface flowrate at injecting well or injecting wells:


Water InjectorGas Injector


q^{\downarrow}_{tW} = B_w \, q^{\downarrow}_W




q^{\downarrow}_{tG} = B_g \, q^{\downarrow}_G


where

water, gas surface flowrates

formation volume factors between separator and sandface pressure/temperature conditions
