Abstract
A downhole gas separator is connected to the lower end of a tubing string. The separator includes a tubular body which has a decentralizer mounted to one side for driving the opposite side of the separator against an interior wall of the casing. This creates a narrow flow zone between the separator body and the adjacent casing wall and a wider flow zone on the decentralizer side of the body. A fluid inlet is provided on the side of the gas separator tubular body facing the narrow flow zone. The fluid in the narrow flow zone has a substantially higher concentration of liquid than the fluid in the wider flow zone. Fluid, primarily liquid, flows through the fluid inlet into a chamber within the separator. A dip tube transfers the fluid from the separator chamber to the pump.
