Abstract:
An appartus for use in recovering gas and fluids from a well having a fluid zone and a gas zone, which includes:perforated casing disposed in the well;production piping disposed in said casing;a gas fluids separator disposed in the casing above the fluid zone and includes a housing sealingly disposed between said casing and said production piping and has a down-hole end and an up-hole end wherein each said end is formed with an open surface, said housing includes a baffle disposed therein to substantially separate and preclude fluids from passing through said up-hole end while permitting gas to emanate through said up-hole end;means communicably connected to the casing for receiving gas cmanating from said uphole end of said housing; anda tubular member surrounding a submersible pump for separating fluids of different densities, said tubular member having an enclosed first end disposed down hole in the casing and an open second end disposed up-hole from said first end, wherein said tubular member is of a diameter to be movably disposed within said casing and operably contain said submersible pump therein, and wherein said tubular member is of a buoyancy such that said tubular member generally floats above the heavier density fluid zone, wherein said tubular member includes a plug axially displaced from said first end and sealably disposed in said housing member forming an air chamber between said first closed end and said plug creating a float aspect to said tubular member.
