Paper: DOWNHOLE DIVERTER GAS SEPARATOR

The Downhole Diverter Gas Separator increases the liquid capacity and gas separation capacity over conventional poor boy or Improved Collar Sized downhole gas separators. The increased separation capacity of the diverter gas separator is provided by using the larger tubing-casing annulus for both gas separation and liquid separation. A simple movable rubber seal is used to divert the flow of liquids and gas vertically from below the rubber seal through a central tube approximately 5 feet in length. When the fluids exhaust into the tubing-casing annulus above the seal, the large annulus flow area reduces the annular gas velocity which allows the liquid to fall back through the large area tubing-casing annulus into the pump intake. Larger tubing-casing annular area below the diverter exhaust port provides high liquid capacity. Large tubing-casing annular area above the diverter exhaust port reduces the gas velocity, reduces liquid holdup and provides high gas separation capacity.
