ABSTRACT:
Disclosed herein is a downhole tool actuation arrangement. The arrangement includes a housing having a chamber, at least one piston in operable communication with the chamber and at least one electrode exposed to the chamber. The electrodes are receptive to a power source. Further disclosed is a method for actuating a downhole tool. The method includes discharging a voltage source through at least one electrode to cause a pressure wave in a fluid surrounding the at least one electrode and moving at least one piston in response to the pressure wave.
