Dual completion of two-layer objects in wells equipped with one ESP, and ensuring tight separation or choking of one of the operated formations without shutting down the submersible motor. Joint development with OOO NPF Packer. The system is optimal for wells with a distance between formation of 4 meters, with a production casing diameter of 140 mm, a temperature of the produced fluid up to 100°C with a flow rate of the shut off formation up to 30% of the well total flow rate.
The surface readout unit transmits power for the downhole sensor and the valve through the power cable of the motor, the latter is also used for data transmission. The downhole sensor is connected to the “star” of the submersible motor, the electric valve is installed under the downhole sensor and controls the inflow volume from the lower formation upon command from the data acquisition unit.
