  • High temperature high pressure acoustic sensor design and packaging
    Patent number: 11910144
    Abstract: A system including a work string and an acoustic device for sensing or transmitting an acoustic signal at least partially traveling through a borehole fluid within a wellbore and a method of operation. The acoustic device includes a compensation fluid, an acoustic transducer at least partially disposed in the compensation fluid and configured to sense the acoustic signal, and a metallic cover that separates the compensation fluid from the borehole fluid and configured to deform in response to a pressure difference between the borehole fluid and the compensation fluid. The acoustic device is conveyed into the wellbore and an electric signal is sent or received with the processor to or from the acoustic transducer.
