Abstract
A deflected drain (2) drilled in a producing zone (1) is equipped for the production of effluents and fitted with a perforated casing (3) and with a tubing (4). A depression is applied in different locations by selectively changing the position of the application points in relation to these locations. The position of the suction ports and/or the area thereof is varied through the selective opening of valves (8) or by displacing the inlet of the tubing (4). A tubing and/or a casing with perforations such that a determined distribution of the depression is obtained can be used. The depression can be produced by a pumping assembly (5) intercalated on the production tubing (4).
