Abstract: A method for using flow rate signals for wireless downhole communication comprises generating a first flow rate signal within a wellbore by altering the flow rate of a first fluid in the well bore, wherein the first flow rate signal comprises at least two detectable characteristics; detecting the first flow rate signal at a first downhole tool disposed within the wellbore; and actuating the first downhole tool in response to detecting the first flow rate signal.

Abstract: Sliding sleeve assemblies including a completion body with an inner flow passageway and one or more ports enabling fluid communication between the inner flow passageway and an exterior of the completion body. A sliding sleeve is arranged within the completion body and has a sleeve mating profile defined on an inner surface, the sliding sleeve being movable between a closed position, where the one or more ports are occluded, and an open position, where the one or more ports are exposed. A plurality of wellbore darts are used and each has a body and a common dart profile that is matable with the sleeve mating profile. One or more sensors are positioned on the completion body to detect the plurality of wellbore darts traversing the inner flow passageway. An actuation sleeve is arranged within the completion body and movable to expose the sleeve mating profile.

Abstract: Methods and systems for using flow rate signals for wireless downhole communication are provided. In one embodiment, the methods comprise: generating a first flow rate signal within a wellbore by altering the flow rate of a first fluid in the wellbore, wherein the first flow rate signal comprises at least two detectable characteristics; detecting the first flow rate signal at a first downhole tool disposed within the wellbore; and actuating the first downhole tool in response to detecting the first flow rate signal.
