Title: COMMUNICATION SIGNAL REPEATER SYSTEM FOR A BOTTOM HOLE ASSEMBLY
Abstract:
A bottom hole assembly includes a cable to transmit power and communication signals. A first measurement-while-drilling tool is coupled with the cable. A second measurement-while-drilling tool is coupled with the cable. An adapter is coupled with the cable and positioned between the first and second measurement-while-drilling tools. The adapter includes a disconnect in the cable that prevents the power from being transmitted through the adapter. A repeater is coupled with the cable and amplifies the communication signals transmitted through the cable.
