Abstract: The disclosure describes a system and a method for locating a cement plug within a wellbore. The system includes a signal transmitter mounted to the cement plug, a receiver at the opening to the wellbore, one clock positioned on the cement plug and in communication with the transmitter, a second clock which is synchronized to the first clock and in communication with the receiver, and a controller for triggering the transmittal of the signal.

Abstract: In another embodiment, a method of drilling a wellbore includes running a drilling assembly into the wellbore through a casing string, the drilling assembly comprising a tubular string, an underreamer, and a drill bit; injecting drilling fluid through the tubular string and rotating the drill bit, wherein the underreamer remains locked in the retracted position; sending an instruction signal to the underreamer via modulation of a rotational speed of the drilling assembly or modulation of a drilling fluid pressure, thereby extending the underreamers; and reaming the wellbore using the extended underreamer.

Abstract: In one embodiment, a method of drilling a wellbore utilizing a drilling assembly having a tubular string, a first underreamer, a second underreamer, and a drill bit. The method includes running drilling assembly into the wellbore through a casing string; injecting drilling fluid through the tubular string and rotating the drill bit; sending a first instruction signal to the first underreamer; sending a second instruction signal to the second underreamer; wherein at least the first or the second instruction signal comprises a synchronization portion and a command portion. In one embodiment, at least one portion of the instruction signals includes modulating a fluid flow rate according to a predetermined fluid flow rate protocol.
