Abstract: A method for automatically selecting a frequency band for transmission of a telemetry signal includes transforming acquired measurements from a time domain to a frequency domain to obtain a spectrum of measurements. The spectrum of measurements is processed to compute a total energy in band and a standard deviation of the power spectral density in band for a plurality of frequency bands. A ratio of the total energy in band to the standard deviation acquiring a plurality of measurements of transmitted telemetry signals and of the power spectral density in band is computed for at least two of the plurality of frequency bands. The frequency band having the highest computed ratio is selected and automatically downlinked to a downhole transmitter.

Abstract: A technique facilitates diagnosis of a telemetry system, such as a mud pulse telemetry system or an electro-magnetic telemetry system. The technique comprises operating a telemetry system in a wellbore and collecting a variety of data. The data may relate to a rig state, a downhole state, a signal state, a surface state, and/or other suitable types of data. The data is processed to determine whether states of operation indicated by the data match states indicating a problem with operation of the telemetry system. If a problem is detected, appropriate information regarding the problem is transmitted for use in correcting the problem.
