Claim Text:
1. A method for transmitting downhole measurements to a surface location, the method comprising: deploying a mud pulse telemetry transmitter in a drill string in a subterranean wellbore; causing the mud pulse telemetry transmitter to modulate a flow of drilling fluid in the drill string, said modulated flow generating an acoustic signal in the drilling fluid, the acoustic signal representative of the downhole measurements; deploying an accelerometer on an exterior surface of a conduit providing fluid communication between a discharge side of a drilling fluid pump and an inlet to the drill string; using the accelerometer to receive the acoustic signal in the drilling fluid; and converting said received acoustic signal in the drilling fluid into representations of the downhole measurements; wherein the accelerometer is deployed at a position corresponding to a maximum amplitude of a standing wave generated in the conduit by the mud pulse telemetry transmitter and a minimum amplitude of a noise signal generated in the conduit by a drilling fluid pump.
