ABSTRACT:
A novel apparatus and method for producing oil and natural gas from an oil well in the later stages of the well's lifetime. The apparatus includes a one-way valve located at the bottom of the conventional production tubing and a string of macaroni tubing inserted inside of the production tubing. The three chambers defined by the casing, the production tubing, and the macaroni tubing, are connectable to either the suction or discharge manifolds of the apparatus, which are in turn connectable to a compressor. With the valves manipulated in the appropriate fashion by the controller, pressure differentials can be created in the down-hole region of the well to force oil first into the macaroni tubing and then force it up and out of the macaroni tubing and to the sales line. An optional plunger may be used to help reduce paraffin or scale buildup in the macaroni tubing.
