Abstract: A method for configuring transmission signals is disclosed. The method includes receiving a signal from a downhole tool in a wellbore. The signal may include a telemetry portion and a noise portion. The method also includes reproducing the telemetry portion based at least partially on the signal. Further, the method includes subtracting the telemetry portion from the signal. The method includes estimating, based at least partially on the subtraction, the noise portion of the signal. The method also includes altering a transmission configuration of the downhole tool based at least partially on the noise portion of the signal.

Abstract: A fluidic modulator having a body forming a flow aperture between an inlet and an outlet, the flow aperture having a nominal diameter less than the inlet diameter and the outlet diameter whereby the flow aperture provides a constriction to a fluid flowing axially from the inlet to the outlet, and a moveable portion operable to alter the flow aperture. To create a modulated pressure pulse the moveable portion may be for example radially shifted in the flow aperture, rotated in the flow aperture, or the rotation of the moveable portion in the flow aperture may be controlled.

Abstract: A method for placement of electrodes includes determining spatial distribution of a signal caused by generating an electromagnetic field in an instrument disposed in drill string used to drill a wellbore. The electromagnetic field comprises encoded measurements from tromagnetic at least one sensor associated with the instrument. Voltages induced by noise are measured across at least one pair of spaced apart electrodes placed at a plurality of positions spaced apart from a surface location of the wellbore. A spatial distribution of noise is estimated using the measured voltages. Positions for placement of at least two electrodes are selected using the spatial distribution of signal and the spatial distribution of noise.

Abstract: A method, a non-transitory computer-readable medium, and a computing system are provided for determining a telemetry mode of a signal. A drilling telemetry signal is received from a downhole tool in a wellbore. A transformation is determined based at least partially upon the drilling telemetry signal. Multiple features are extracted based at least partially upon the transformation. A decision region is identified based at least partially upon the features. A telemetry parameter is identified based at least partially upon the decision region. A telemetry mode of the drilling telemetry signal is determined based at least partially upon the telemetry parameter. The drilling telemetry signal is decoded based at least partially upon the telemetry mode.

Abstract: A method includes receiving a signal having a telemetry portion and a noise portion. The method may also include identifying one or more harmonic frequencies in the signal. The method may also include determining whether the one or more harmonic frequencies are in a predetermined frequency band. The method may also include determining whether a signal-to-noise ratio (SNR) of the signal is below a predetermined SNR threshold. The method may also include generating one or more notifications in response to the determination whether the one or more harmonic frequencies are in the predetermined frequency band and the determination whether the SNR is below the predetermined SNR threshold.
