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.
Claims23
A downhole tool actuation arrangement comprising:
- a housing having a chamber;
- at least one piston in operable communication with the chamber;
- and
- at least one electrode exposed to the chamber, said electrode being receptive to a power source;
- at least one capacitor in operable communication with the at least one electrode;
- and
- at least one inflatable or packer in actuation communication with the piston, whereby movement of the piston causes actuation of said inflatable or said packer.
A method for actuating a downhole tool comprising:
- 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;
- and
- actuating an inflatable or a packer in response to movement of the piston.
