ABSTRACT:
A device comprising a flow string of two parts separated by an assembly for pumping effluents and a side-entry sub lowered into an equipped well provided with a pipe perforated in the part thereof going through a producing zone. At least one assembly of measuring instruments and possibly a device for homogenizing effluents before their treatment are arranged at a bottom end of the lower part of the string. The measuring assembly is connected with the surface installation by a multiconductor cable passing from an inside of the string to the outside at the level of the side-entry sub. The pumping assembly is positioned in a well zone accessible to the produced effluents but far enough from the most deflected and/or the narrowest well portions, in order to facilitate the setting of the pumping assembly and to avoid any risk of jamming or crushing of the cable connected with the assembly of the measuring instruments.
