Abstract
A single use setting tool and associated method for actuating a tool in a wellbore may include an inner piston having a piston proximal end, a piston distal end, and a piston annular wall that defines a piston cavity. The setting tool may include a gas-generating power charge positioned within the piston cavity. The power charge may extend along a longitudinal axis from a proximal end to a distal end and have at least two different widths along its length. The power charge may further include a tapered portion. The setting tool may further include a piston extension connected to the piston distal end. The inner piston may further include a shear element groove circumferentially extending in an outer surface of the inner piston, for receiving a shear element.
