Abstract
A well production apparatus is provided for a well having a pressure control device operatively associated with the well for controlling pressure within the apparatus and well, wherein the apparatus includes a buoyant tubing member of a sufficient diameter to contain a submersible pump therein which is connected to a compressor. The apparatus further includes a gas fluids separator in the casing of the well. A fluids composition sensor and transmitter are provided for aiding in operating the apparatus.
Claims4
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;
- and
- a 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.
