Claim 8:
9. A method comprising:
disposing a gas-liquid separator and a production tubing in a casing, wherein the gas-liquid separator comprises a swirl enhancer, a collector, and a cross-over section disposed below the swirl enhancer;
receiving a wellbore fluid containing liquids and gases through the swirl enhancer;
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 wellbore fluid containing liquids and gases and comprises one or more guide vanes to provide the wellbore fluid containing liquids and gases with a velocity in a tangential direction;
a 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

separating liquids and gases in the swirl enhancer under centrifugal effect;
further separating liquids and gases toward different ends of the collector under gravity; and
directing the liquids from the collector to the production tubing through the cross-over section.
