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.

Abstract: A single use setting tool and associated method for actuating a tool in a wellbore may include an inner piston with an annular wall defining a piston cavity. A portion of the inner piston including the piston cavity may be positioned within a central bore of an outer sleeve, and the inner piston and the outer sleeve may be slidable relative to one another. A portion of the inner piston may extend beyond an end of the outer sleeve and have a shock absorbing wedge positioned thereon, and the end of the outer sleeve may have a cutout for receiving the shock absorbing wedge. A bi-directional gas-generating power charge may be positioned in the piston cavity and include a power charge having a booster positioned in an indentation adjacent each of a first end and a second end of the power charge.

Abstract: A single use setting tool for actuating a tool in a wellbore includes an inner piston extending through a central bore of an outer sleeve. The inner piston has a seal adapter portion and a piston cavity housing an initiator holder for receiving a push-in detonator. A gas diverter channel is open to and extends from the piston cavity through an annular wall of the piston, to transfer gas pressure to a gas expansion chamber for stroking the outer sleeve. A method of actuating a wellbore tool with a single use setting tool includes inserting an initiator into the initiator holder, attaching a tandem seal adapter to the seal adapter portion of the inner piston, and relaying an electrical signal to a line-in portion of the initiator, to initiate the initiator. The single use setting tool may be used in a wellbore tool string.
