Abstract:
The present invention provides a gas-liquid separator/connector having three concentric tube device made such that flow of fluids from a ESP enters the bottom and are diverted into the largest of the three concentric tubes located as the outside tube. The relatively large space between the inside tube and the outside tube allows for the gas to separate from the liquid. The gas continues to rise to the surface in the tubing-casing annulus. The liquid now can enter by gravity the third tube that is placed outside the inner tube (the tubing) and the large external tube. This third concentric tube is not as long as the large outer tube and is connected at the bottom to become the entrance to the pump intake for the beam pump or PCP. The pump intake for the beam pump or PCP is a part of the smallest inner tube of the connector.
