Abstract
A dual-configuration shear bolt for coupling components of an assembly is provided. The dual-configuration shear bolt can include a body defining a chamber and a pin in the chamber. The body can include a shear portion. The pin can move between a shearing position and a non-shearing position. The pin can be retained within the shear portion by a retaining mechanism in the non-shearing position. The pin can be moved away from the shear portion to the shearing position.
Claims20
A dual-configuration shear bolt comprising:
- a body defining a chamber, the body having a shear portion;
- and
- a pin positioned in the chamber, the pin being moveable between a shearing position and a non-shearing position, the pin being retained within the shear portion by a retaining mechanism in the non-shearing position, the pin being movable away from the shear portion to the shearing position for the shear bolt.
A downhole assembly comprising:
- a first component;
- and
- a second component coupled to the first component with a dual-configuration shear bolt, the dual-configuration shear bolt comprising:
- a body defining a chamber, the body having a shear portion that has a smaller width than another portion of the body;
- and
- a pin positioned in the chamber, the pin being moveable between a shearing position and a non-shearing position, the pin being retained within the shear portion by a retaining mechanism in the non-shearing position, the pin being movable away from the shear portion to the shearing position for the shear bolt.
