ABSTRACT:
In one aspect of the invention, a high-speed measurement system has a first and a second well bore. A first and second plurality of network nodes is integrated into and spaced at intervals along the first and second well bore, respectively. A communications channel connects each plurality of network nodes forming a first and second downhole network. A signal source is in communication with the first downhole network and a signal receiver is in communication with the second downhole network; and a common clock source is in communication with both the signal source and the signal receiver over the first and second downhole networks, respectively. The signal source and signal receiver are synchronized with the clock source and the signal source is adapted to send a signal to the signal receiver through a subterranean formation.
