Methods of employing and using a hybrid transponder system to determine the size, extent, and orientation of a hydraulic fracture of a reservoir, are provided. An exemplary method can include the steps of inserting a plurality of transponders into a fluid, injecting the fluid carrying the transponders through casing perforations and at least one fracture aperture in a wellbore and into a hydraulic fracture, actuating each of the transponders by a reader to provide an acoustic return signal to the reader, determining a three-dimensional position of each of the transponders, mapping the location of the each of the transponders, and determining characteristics of the hydraulic fracture responsive to the three-dimensional position of each of the plurality of transponders. The method can be implemented utilizing a reader including an RF transmitter and one or more acoustic receivers along with typically a substantial plurality of transponders each containing an RF receiver and an acoustic transmitter. |
