A method is described for estimating either flowback or the reservoir fluids production rate from either one individual inlet or the contribution from several inlets separated by intervals in a wellbore located in an oil and/or gas reservoir. The wellbore may include a casing with a plurality of magnetic irregularity elements, such as casing collars, to generate magnetic perturbations within the casing. In the method, one or more sensor elements are delivered in such a way that the flow drags them while the sensor elements record in time the magnetic perturbations generated by the magnetic irregularity elements. The known location of the magnetic irregularity elements and the reading of perturbations enables estimating the velocity of the sensor element(s) along the path direction of the casing, to determine the velocity of the fluid.

Real time monitoring of a predetermined set of downhole parameters related to downhole status of a well comprises deploying a casing module as part of a casing string to a first predetermined location downhole, the casing module comprising a set of components, deploying a tubing module as part of a tubing string, typically within the casing string, where the tubing module comprises a set of tubing module components, and deploying a power generator to a distance within the well, typically as part of the tubing string and typically as part of the tubing module, and operatively connecting the power generator to the tubing module to effect power transmission from the power generator, generated downhole, to the tubing module and from the tubing wireless power transfer transmitter to the casing module. Data related to a predetermined set of downhole parameters related to downhole status of the well are transmitted from the casing module via a wireless data short hop transceiver to a tubing module wireless short hop data transceiver, the data the data and then from a surface data transceiver to a surface location.
