Electric pressure actuating tool and method
View Patent ↗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.
1. 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;
moving at least one piston in response to the pressure wave; and
a downhole tool by the moving of the piston.
2. A method for actuating a downhole tool as claimed in claim 1 wherein the moving is incremental and includes ratcheting of the at least one piston.
3. A method for actuating a downhole tool as claimed in claim 1 wherein the moving of the at least one piston further includes compressing a fluid in a chamber that is in operable communication with the at least one piston.
4. 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;
moving at least one piston in response to the pressure wave; and
controlling a setting sequence of a packer.
5. A method for actuating a downhole tool as claimed in claim 4 wherein said controlling is partially setting, holding and final setting.
6. A method for actuating a downhole tool as claimed in claim 5 wherein said controlling further includes releasing the setting tool.
