Claim Text:
1. A gas separator assembly for a use with a downhole pump supported at a bottom end of a production tubing string received within an outer casing of a hydrocarbon producing well, the assembly comprising: an inner casing member defining a primary passage extending longitudinally therethrough between opposing first and second ends of the inner casing member, the first and second end are both connected in series with the outer casing of the well; an outer casing member supported externally of the inner casing member so as to define a secondary passage extending longitudinally and externally of the primary passage between a first end and a second end of the secondary passage; a first port in communication between the primary passage of the inner casing member and the secondary passage of the outer casing member adjacent the first end of the secondary passage such that the first end of the secondary passage only communicates with the primary passage through the first port; a second port in communication between the primary passage of the inner casing member and the secondary passage of the outer casing member adjacent the second end of the secondary passage such that the second end of the secondary passage only communicates with the primary passage through the second port; and a barrier arranged to be supported in the primary passage to seal the primary passage at a location between the first port and the second port so as to define a sump area in the primary passage between the barrier and the first port which is arranged to receive an inlet of the downhole pump therein whereby produced fluids in the outer casing below the assembly are directed from the outer casing below the assembly upwardly through the secondary passage from the second port to the first port and downwardly through the primary passage from the first port to the inlet of the downhole pump.
