Abstract
A setting tool disposed on tubing runs a packer into casing. During a setting process, a plug is engaged on a seat of an intensifying piston disposed in the tool. Tubing pressure applied against the seated plug moves the intensifying piston, which produces intensified pressure on fluid in a first volume of the intensifying piston communicated to a second volume of a setting piston. In response, the setting piston moves on the tool toward the packer's packing assembly. At some point in the process, the seated plug can be released from the seat. Additionally in the process, the second volume can fill with actuation fluid drawn through a fill valve from an annular space between the setting tool and the casing. The intensifying piston can then be reset as the actuation fluid is communicated from the second volume to the first volume.
