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.

Abstract:

A method for steering a downhole tool includes receiving an electromagnetic (EM) signal from the downhole tool. The downhole tool is in a wellbore in a formation. The EM signal comprises a gap voltage and a gap current that are measured across a gap sub in the downhole tool. The method also includes determining a gap impedance based at least partially upon the gap voltage and the gap current. The method also includes determining a first formation resistivity at a first location in the wellbore based at least partially upon the gap impedance. The method also includes steering the downhole tool based at least partially upon the first formation resistivity.
