Abstract (en)
[origin: EP0484207A1] A diverted drain (2) drilled in a production zone (1) is equipped for the production of fluids and is provided with a perforated casing (3) and with a production tube (4). A vacuum is applied at various locations by a selective modification of the position of the application points in relation to these locations. The position of the suction ports and/or their area is varied by a selective opening of valves (8) or by a displacement of the entrance of the production tube (4). A tube and/or a casing having perforations such that a specific vacuum distribution is obtained can be used. The vacuum can be generated by a pumping assembly (5) inserted on the production drain. <??>The invention is used for the activation or stimulation of oil-bearing zones. <IMAGE>
