  • Patent number: 11143022
    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.
    Type: Grant
    Filed: August 14, 2016
    Date of Patent: October 12, 2021
    Assignee: Halliburton Energy Services, Inc.
    Inventors: Li Gao, Ramachandhran Balasubramanian
  • Patent number: 10941652
    Abstract: Systems and methods for terahertz modulation in a terahertz frequency band from about 0.1 terahertz to about 10 terahertz propagating in a wellbore intersecting a subterranean earth formation. A transmitter generates the EM radiation in the terahertz frequency band. A modulator located in the wellbore receives the EM radiation and generates an amplitude modulated signal with the EM radiation.
