Patent ID: 7533726

Claim:
A method for increasing the production of a formation gas from a well bore penetrating a gas producing subterranean formation wherein the formation gas has a water content that results in the formation of condensate water from the formation gas as the formation gas passes up the well bore to the surface so as to cause the condensate water to accumulate at the bottom of the well bore and impede the flow of formation gas into the well bore from the gas producing subterranean formation, the method comprising: injecting a volume of a diluent gas having a water content less than the water content of the formation gas into the well bore at a pressure insufficient to cause the diluent gas to invade the gas producing formation and insufficient to push liquid through the well bore, toward the surface yet sufficient to cause the diluent gas to mix with and dilute the formation gas in the well bore adjacent the gas producing formation at bottom hole pressure and temperature conditions to produce a production gas that has a water content in equilibrium at surface pressure and temperature conditions to prevent the formation and deposition of condensate water as the production gas passes to the surface; and recovering the production gas at the surface.
