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.
