Abstract:
1. A multi-channel downhole telemetry system disposed within a wellbore comprising: a downhole transmitter located at a first position within said wellbore and operable to optically transmit a first data stream on a first optical channel and a second data stream on a second optical channel; a downhole receiver located at a second position within said wellbore and operable to receive the first data stream and the second data stream; wherein said first position within said wellbore is not within a line-of-sight of said second position within said wellbore, and an optically transmissive fluid disposed in the wellbore that provides a medium for the optical transmission of the first data stream and the second data stream between the downhole transmitter and the downhole receiver, the optically transmissive fluid containing suspended solids having refraction surfaces that scatter the optically transmitted data streams in the wellbore.
