The present invention is used in conjunction with a multi-channel system of a production string for deployment in gas, condensate or oil wells. An end-piece is placed at the entrance to such multi--channel system. It includes a semi-enclosed space helping to increase the proportion of gas phase entering the system at its bottom entrance. Increased proportion of gas allows lifting liquids and/or solids from the wellbore with greater efficiency. Examples of using the invention include wellbore water removal for gas wells with liquid loading problems, for solution gas drive or gas cap driven oils wells during their initial "natural flowing phase", or during gas re- injection or gas-lift recovery operations for oil wells. It can also be used for gas-lifting water in water wells.
