Abstract
A disposable setting tool may include an outer housing and a piston. The outer housing may have a proximal end portion defining a power charge chamber and a distal end portion. The outer housing may define a longitudinally-extending bore configured for holding a medium therein. The bore and the power charge chamber may be divided from one another by a proximal wall. The piston may be configured for receipt in the bore and to move axially relative to the outer housing.

A disposable setting tool for actuating a tool in a wellbore, comprising:
- an outer housing having a proximal end portion defining a power charge chamber, and a distal end portion, the outer housing defining a longitudinally-extending bore configured for holding a medium therein, the bore and the power charge chamber being divided from one another by a proximal wall;
- and
- a piston configured for receipt in the bore and to move axially relative to the outer housing,
- wherein the outer housing defines a ventilation hole radially therethrough for permitting a flow of the medium out of the bore in response to axial movement of the piston.
A tool for setting a plug in a wellbore, comprising:
- an outer housing including:
- a proximal end portion defining a power charge chamber;
- a distal end portion configured for coupling to a setting sleeve;
- and
- an intermediate portion extending between the proximal end portion and the distal end portion, the intermediate portion having an annular inner surface defining a longitudinally-extending central bore configured for holding a dampening medium therein;
- a power charge received in the power charge chamber;
- and
- a piston received in the central bore and configured to translate relative to the annular inner surface, wherein the outer housing defines a longitudinally-extending gas channel in fluid communication with the power charge chamber and the piston such that the piston is configured to move proximally within the central bore in response to a combustion of the power charge,
- wherein the outer housing defines a ventilation hole radially therethrough for permitting a flow of the dampening medium out of the central bore during proximal movement of the piston through the central bore.
A tool for setting a plug in a wellbore, comprising:
- an outer housing including a proximal end portion defining a power charge chamber, and a distal end portion configured for coupling to a setting sleeve;
- a power charge positioned in the power charge chamber;
- a dampening medium stored in the outer housing and positioned distally of the power charge;
- and
- a piston received in the outer housing and hydraulically coupled to the dampening medium, wherein the outer housing defines a longitudinally-extending gas channel having a proximal end portion in fluid communication with the power charge chamber, and a distal end portion positioned adjacent the piston, such that the piston is configured to move proximally within the outer housing in response to a combustion of the power charge,
- wherein the outer housing defines a ventilation hole radially therethrough for permitting a flow of the dampening medium out of the central bore during proximal movement of the piston through the outer housing.
