Abstract

A well tool can comprise a fluid input, a fluid output and a fluidic oscillator which produces oscillations in a fluid which flows from the input to the output. The fluidic oscillator can include a vortex chamber with inlets, whereby fluid enters the vortex chamber alternately via the inlets, the inlets being configured so that the fluid enters the vortex chamber in different directions via the respective inlets, and a fluid switch which directs the fluid alternately toward different flow paths in response to pressure differentials between feedback fluid paths. The feedback fluid paths may be connected to the vortex chamber. The flow paths may cross each other between the fluid switch and the outlet.
