Abstract:
An electromagnetic telemetry system adjusts telemetry parameters which may include carrier frequency, signal amplitude and/or data encoding protocol to achieve reliable data transmission and to conserve power. In some embodiments, sweep signals transmit a range of carrier frequencies and the parameters are determined in part by analyzing the received sweep signals. In some embodiments, different parameters are selected automatically based on a mode of drilling.

Claim (Index 1):
A method for downhole electromagnetic (EM) telemetry in a downhole drilling operation, the method comprising the steps of:\n determining a mode of the drilling operation; sending a set of EM sweep signals from a downhole EM telemetry system located at a downhole location to an uphole system located at a surface location, each of the EM sweep signals having a different frequency; determining whether each of the EM sweep signals is received at the uphole system and, for the EM sweep signals received, measuring parameters of the received EM sweep signals, the parameters comprising at least one of signal strength and signal-to-noise-ratio; based at least in part on: the mode of drilling operation, the EM sweep signals received, and the parameters measured, determining a protocol for downhole data transmission, the protocol specifying protocol parameters including one or more of signal frequency, signal amplitude, and data encoding scheme; and configuring the downhole EM telemetry system to transmit data to the uphole system using the protocol.
