Patent number: 8248266Abstract: A system and method for communicating data between a downhole tool and a surface controller is provided that comprises a rotating drill string extending in a borehole and having a downhole telemetry module disposed proximate a bottom end thereof and transmitting a first signal across a telemetry channel. A surface telemetry module is disposed proximate a top end of the rotating drill string and is adapted to receive the first signal transmitted by the downhole telemetry module across the transmission channel. The surface telemetry module has a radio frequency transmitter disposed therein for transmitting a second signal related to the first signal. A stationary communication module has a radio frequency receiver adapted to receive the second signal.Type: GrantFiled: January 12, 2009Date of Patent: August 21, 2012Assignee: Baker Hughes IncorporatedInventors: John D. Macpherson, Frank W. Shepard, Ralf Zaeper, Volker Krueger
