Abstract
A shifting tool including a flow sleeve having a fluidic diode to facilitate flow from an exterior port to an interior port along the flow sleeve and restrict flow in the opposite direction. In a first configuration of the shifting tool, a flow path extends from the exterior of a case, via the exterior port, along the flow sleeve, and, via the interior port, to a flow bore of an operating mandrel. Upon exposure to a pressure differential between a cavity in which the flow sleeve is positioned and the flow bore above a threshold pressure differential, a shear pin breaks, such that the shifting tool assumes the second configuration. In the second configuration, the operating mandrel has shifted longitudinally whereby a snap ring extends into a recess or groove in an outside surface of the operating mandrel, to hold the operating mandrel in the second configuration.
