Abstract
A method for installing a tool in a downhole system including running the tool to a target location within a tubular structure, creating a magnetic pulse, and urging the tool toward the tubular structure at a minimum velocity of 200 meters per second with the magnetic pulse. A method for actuating a downhole tool including creating a magnetic pulse, coupling the magnetic pulse to a workpiece and moving the workpiece with the pulse, the workpiece achieving a minimum velocity of 200 meters per second.
Claims12
A method for installing a tool in a downhole system comprising:
- running the tool to a target location within a tubular structure;
- creating a magnetic pulse;
- causing a chamber of the tool or adjacent the tool to deform from a first volume to a smaller volume;
- pressurizing a fluid within the chamber with the deformation;
- using the pressurized fluid to move another component of the tool or the downhole system in a direction other than a direction of the magnetic pulse.
A method for actuating a downhole tool comprising:
- creating a magnetic pulse;
- coupling the magnetic pulse to a workpiece;
- moving the workpiece with the pulse, the workpiece causing deformation of a chamber;
- moving another component in a direction other than a direction of the magnetic pulse.
