Abstract
A disclosed subsurface detection system includes a first communication device positioned in a borehole and configured to scan a plurality of frequencies in at least a portion of an annulus surrounding an exterior of a tubing including the casing string in the borehole or an interior of the tubing including the casing string. The plurality of frequencies include a first frequency corresponding to a first type of RFID tag and a second frequency corresponding to a second type of RFID tag. The first communication device is further configured to detect a response to the scan from an RFID tag of the first type or the second type in the portion of the annulus or the interior of the tubing. The system further includes a processor configured to receive communication of the detected response from the first communication device, and based on the detected response, determine one or more characteristics of an environment around the corresponding RFID tag (e.g., an intrinsic impedance of a fluid material in the environment).
