Schlumberger's downhole wireless Muzic

摘要

Schlumberger has just released 'Quartet' a reservoir testing system using wireless telemetry ('Muzic,' what else!) to provide bi-directional downhole communications. Muzic uses mud pulses to transmit data to and from the test tool. For deepwater applications, repeaters are run in the test string to enhance signal to noise. The relatively low bandwidth offered by the mud pulse system is OK for well testing operations that last from days to weeks.
