METHOD AND APPARATUS FOR THERMALLY ACTUATING AND UNACTUATING DOWNHOLE TOOLS

A method for actuating a downhole tool comprising disposing a phase change material having selected volumetric change upon phase change in contact with a tool or tool component. Raising a temperature of the material above the phase change point of the material. Directing a resultant force of the vol...

Summary:A method for actuating a downhole tool comprising disposing a phase change material having selected volumetric change upon phase change in contact with a tool or tool component. Raising a temperature of the material above the phase change point of the material. Directing a resultant force of the volumetric increase of the phase change material to the tool or tool component.
