Abstract
Near-field magnetic resonance is used to retrieve information stored in sensors passing through a fluidic channel in a fluidic medium, and can also be used for recharging a power source in the sensors. The sensors have been previously injected into a downhole and/or reservoir environment, and are then retrieved in order to access the information the sensors have obtained by measuring physical and/or chemical properties of the downhole and/or reservoir.

A system for reading information from sensors carried in a fluidic medium, comprising:
- equipment for extracting a fluid from a geological formation, wherein the fluid contains a plurality of sensors that have information stored in an electronic storage device implemented within each of the plurality of sensors;
- equipment for transferring the extracted fluid through a fluidic channel;
- a self-resonator comprising a wire wound around the fluidic channel;
- a coupling loop positioned in proximity to the self-resonator;
- a RF signal source coupled to the coupling loop, whereby the RF signal source is configured to feed a RF signal into the coupling loop, wherein the coupling loop and the self-resonator are configured so that the coupling loop inductively excites the self-resonator to its self-resonance to generate a magnetic field suitable to retrieve the information from each of the plurality of sensors as they pass in proximity to the coupling loop.
