Assignee:

DynaEnergetics Europe GmbH - Troisdorf

International Classification:

E21B 23/00
E21B 41/00

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.

International Classification:

E21B 23/04

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.
