Abstract: A downhole separator (10) separates gas from well fluids which are pumped intermittently to the surface. The separator includes an outer tubular housing (12) and an inner flow tube (22) for passing well fluids to the surface after separation of the gas from the well fluids. A vortex flow generator or spiral gas separator (20) imparts a helical flow to effect separation of the gas from the well fluids. Gas from the gas chamber flows upward past the vortex flow generator when the pump is not pumping well fluids to the surface.
