Abstract
A device for vibrating tubing as it is inserted into a wellbore is disclosed. The device has a fluidic switch that has no moving parts. The fluidic switch is connected to a piston that oscillates back and forth in a cylinder. The piston is the only moving part. As the piston oscillates, it blocks and unblocks openings in the cylinder or other components. The movement of the piston controls the timing of the oscillation, and also generates an impulse or vibration. The vibration may reduce the friction between the tubing and the wellbore.
