ABSTRACT:
A split-stream method and apparatus for preventing the accumulation of liquids, such as water or oil, in subterranean gas wells having low shut-in bottom hole pressures is provided. A compressor whose capacity can be less than the theoretical adiabatic horsepower for full wellhead depletion, is used to remove a two-phase liquid-gas mixture through a secondary fluid transmission conduit. Production of dry gas in larger quantities through a primary production conduit is then possible since liquids cannot accumulate to kill the well. An optional mechanism for initiating production in very low pressure wells and a means of preventing the buildup of paraffin is also described.
