Abstract

A system for performing a wellbore operation while a fluid circulates in a wellbore may include a string, a fluid circulation system, a control device, The string may include at least a first tubular section and a second tubular section. The a fluid circulating system has a first fluid path and a second fluid path, wherein only one of the first fluid path and the second fluid path circulate the fluid into the string at a specified time. The control device selects one of the first or second fluid path through which to convey the fluid into the string, at least one signal generator in hydraulic communication with the circulating fluid, the at least one signal generator configured to impart at least one pressure signal into the circulating fluid, and at least one pressure transducer in pressure communication with the circulating fluid and configured to detect the imparted at least one pressure signal, wherein the at least one signal generator and the at least one pressure transducer form a communication link, the communication link configured to convey information between at least two locations along a flow path of the circulating drilling fluid, irrespective of the fluid path selected by the control device to convey the fluid into the drill string.
