Description
The high-speed EM telemetry delivers real-time data at speeds four times faster than conventional mud pulse. Operators can make better decisions using more information without reducing ROP.
With two-way electromagnetic communication, the operator can downlink commands to the tool. The EM transmitter can be paired with a mud pulser in one string to provide dual telemetry. The EM MWD system can transmit high-resolution data from all PDT sensors at a reliable high speed. Signal-decoding technology filters noise from the transmission.
