Claim 4:
5. A system comprising:
a gas-liquid separator and a production tubing, both disposed in a casing;
wherein the gas-liquid separator comprises:
a swirl enhancer that receives a mixture of liquids and gases, at least a portion of the swirl enhancer forms a conical section;
a collector that receives liquids and gases from the swirl enhancer; and
a cross-over section disposed below the swirl enhancer and fluidly connecting the collector to the production tubing,
wherein
the swirl enhancer is disposed to an outer periphery of the production tubing and inside the collector,
the swirl enhancer comprises:
an inlet that receives the mixture of liquids and gases and comprises one or more guide vanes to provide the mixture of liquids and gases with a velocity in a tangential direction;
the conical section having a radius that gradually decreases from bottom to top of the conical section, such that a tangential velocity of liquids increases at a different level from a tangential velocity of gases, due to difference between a density of liquids and a density of gases; and
an outlet at the top of the conical section having a radius smaller than a radius of the inlet, and

the collector receives liquids and gases from the outlet.
