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.
An end-piece for a multi-channel system positioned in a reservoir well, said multi-channel system having a bottom entrance and a plurality of passageways configured to transport a multi-phase flow including at least a gas phase from said reservoir along said well, said multi-channel system extending from a top portion of said well to location of liquid accumulation, said end-piece comprising a sleeve extending from said bottom entrance towards said reservoir to direct said multi-phase flow towards said bottom entrance of said multi-channel system, said end-piece including a semi-enclosed space opened towards said reservoir, said space sized to increase proportion of said gas phase in said multi-phase flow, whereby deployment of said multi-channel system equipped with said end-piece prevents liquid accumulation in said well.
An end-piece for a multi-channel system positioned in a well extending from a reservoir, said multi-channel system having a plurality of passageways extending from a bottom entrance facing said reservoir, said multi-channel system configured to transport a multi-phase flow including a gas phase from said reservoir along said well, said multi-channel system extending from a top portion of said well to location of liquid accumulation, said end-piece comprising a sleeve extending from said bottom entrance towards said reservoir to direct said multi-phase flow towards said bottom entrance of said multi-channel system, said sleeve being at least equal or greater in cross-section than said multi-channel system so as to concentrate said gas phase in said multi-phase flow, whereby deployment of said multi-channel system equipped with said end-piece prevents liquid accumulation in said well.
A method for increasing liquid lift in a well extending from a reservoir, the method comprising the following steps:
