Abstract
An assembly includes a fastener deployable in a wellbore and actuated by a shape-memory alloy. The shape-memory alloy releaseably interlocks multiple components deployed in the wellbore. The physical shape of the shape-memory alloy can be selectively changed between a first shape and a second shape.
Claims20
An assembly, comprising:
- a fastener deployable in a wellbore, the fastener comprising a shape-memory alloy for releaseably interlocking a plurality of components deployable in the wellbore, wherein a physical shape of the shape-memory alloy is selectively changeable between a first shape and a second shape.
A system, comprising:
- a fastener comprising a shape-memory alloy for releaseably interlocking a plurality of components deployable in a wellbore, wherein a physical shape of the shape-memory alloy is selectively changeable between (i) a first shape configurable for interlocking the plurality of components and (ii) a second shape configurable for releasing the plurality of components;
- and
- a temperature-control device for heating or cooling the shape-memory alloy to change the shape-memory alloy between the first shape and the second shape.
A method, comprising:
- interlocking a plurality of components deployed in a wellbore with a fastener comprising a shape-memory alloy, wherein a physical shape of the shape-memory alloy is selectively changeable between a first shape and a second shape;
- heating the fastener, by a temperature-control device, above a transition temperature;
- changing the shape-memory alloy from the first shape to the second shape;
- and
- releasing the plurality of components from one another.
