  • High efficiency acoustic transmitting system and method
    Patent number: 6697298
    Abstract: The present invention includes a well system having a sensor; a controller for converting the sensor output, a signal conducting mass, a magnetostrictive actuator for inducing an acoustic wave the signal conducting mass, a reaction mass being greater than the signal conducting mass, an acoustic wave receiver up-hole, and a processor for processing a signal from the acoustic wave receiver and for delivering the processed signal to an output device.
    Type: Grant

  • Adjustable shear valve mud pulser and controls therefor
    Patent number: 6469637
    Abstract: A telemetry system involving a shear-type mud pulser valve as the preferred embodiment is described. The control system includes a motor driver for the mud pulser which, in essence, moves one movable plate with respect to a stationary plate to create openings of various sizes. Pressure is sensed uphole of the pulser valve and is compared in real time to the desired pressure pulse amplitude. By allowing different relative rotational positions of the rotatable plate with respect to the stationary plate, different amplitudes can be achieved to further enhance the transmission of data to the surface. The control system compensates for wear in the mud pulser valve itself as well as drastic changes in mud flow and pressure. The configuration is simple and not prone to fouling from grit or other particles in the mud.
