  • Drilling fluid pressure pulse detection using a differential transducer
    Publication number: 20060250893
    Abstract: An apparatus for detecting mud pulse telemetry signals includes a differential transducer. In various exemplary embodiments, a high-pressure side of the differential transducer is in fluid communication with either drilling fluid in a standpipe (which is in fluid communication with drilling fluid in the borehole) or a gas chamber of a pulsation dampener. Exemplary embodiments typically further include a pressure delay module in fluid communication with the low-pressure side of the differential transducer and the gas chamber of the pulsation dampener. The invention is intended to advantageously improve the reliability and bandwidth of mud pulse telemetry communications in oilfield drilling applications.
