<p>Systems (30) for determining a size, extent, and orientation of a hydraulic fracture (21) of a reservoir (23), are provided. An exemplary system (30) can include a plurality of RFID transponders (65) modified to include an acoustic transmitter (97), and an RFID reader (63) modified to include both an RF transmitter and a pair of acoustic receivers (75), to be deployed in a wellbore (27) adjacent a hydraulic fracture (21). The system (30) includes a computer (31) including memory (35) storing program product (51) configured to receive acoustic return signal (77) data to determine the three-dimensional location of each RFID transponder (65) within the reservoir (23), to map the location of each RFID transponder (65), and to responsively determine the size, extent, and orientation can be determined.</p> |
