Abstract
A system and method for signal communication using a piezoelectric fiber composite (PFC) sensor. A telemetry module is locatable within a borehole intersecting a subterranean earth formation. The PFC sensor is coupled to a carrier in communication with the telemetry module. The PFC sensor is configured to generate a signal indicative of a stress in the carrier. A processor in communication with the PFC sensor is configured to convert the signal generated by the PFC sensor into a telemetry signal transmitted by the telemetry module.
Claims19
A telemetry system for use in a borehole intersecting a subterranean earth formation, comprising:
- a telemetry module locatable within the borehole and configured to receive data and transmit the data in a telemetry signal;
- a carrier in communication with the telemetry module, the telemetry module configured to transmit the telemetry signal through a fluid in the carrier;
- a piezoelectric fiber composite (PFC) sensor coupled to the carrier and configured to detect stress in the carrier indicative of the telemetry signal and generate a signal indicative of the detected stress in the carrier;
- and
- a processor configured to receive the signal from the PFC sensor.
A method of telemetry communication in a borehole intersecting a subterranean earth formation, comprising:
- coupling a piezoelectric fiber composite (PFC) sensor to a carrier at the surface;
- receiving data in the borehole;
- transmitting a telemetry signal from a location in the borehole through a fluid within the carrier to induce a stress in the carrier, the telemetry signal including the received data;
- detecting the stress in the carrier and generating a signal indicative of the stress in the carrier using the PFC sensor;
- and
- converting the signal generated by the PFC sensor into the telemetry signal.
