Gas material balance continued

[@sachindhandhan1702]

Sir, in writing the equation in surface condition, We should be divided by Bw, not by Bg?

[@BoffyBlunt]

A good question: the water influx We is the reservoir volume of water that goes into the gas field. It displaces the same volume We of gas. This gas when produced to the surface has a volume We/Bg. This is an equation for gas production, not water, so we use Bg.
