A system inserted between the base of a riser ( 5 ) and a production well flowline for collecting an effluent consisting of at least a gas phase and a liquid phase, includes a capacity ( 1 ) including an inlet port for the effluent and two outlet ports, one in the upper part of said capacity for the gas phase, the other in the lower part for the liquid phase communicating with the base of the riser, a gas supply line ( 2 ) connecting the gas outlet port to the riser at a predetermined height H, including a flow control valve ( 3 ), and an instrumentation set for locating the level of the liquid/gas interface in the capacity, a computer receiving the instrumentation data for determining the instructions for controlling said flow control valve so as to adjust the volume of gas fed at height H into the riser.
