Abstract
A seal including a first metal component; a second metal component couplable with the first metal component; and a shape memory alloy having a first state and a second state, the first state and the second state being different in at least one dimension, wherein in response to an external stimulus, the shape memory alloy transitions in one or more dimension from the first state to the second state thereby forming at least one metal-to-metal seal.
Claims20
A seal comprising:
- a sleeve that includes a first portion and a second portion;
- a mating component couplable with the sleeve based on the first portion of the sleeve surrounding at least part of the mating component;
- and
- a shape memory alloy disposed at a surface of the sleeve, the shape memory alloy having a first state and a second state, the first state and the second state being different in at least one dimension, wherein in response to an external stimulus, the shape memory alloy transitions in one or more dimensions from the first state to the second state;
- and
- an outer component that is welded to the second portion of the sleeve to isolate the shape memory alloy from an external environment, wherein the transition of the shape memory alloy to the second state leads to formation of at least one metal-to-metal seal between the first portion of the sleeve and the mating component in response to the external stimulus.

A method of creating a seal comprising:
- providing a downhole tool comprising:
- a sleeve that includes a first portion and a second portion;
- a mating component couplable with the sleeve based on the first portion of the sleeve surrounding at least part of the mating component;
- a shape memory alloy disposed at a surface of the sleeve, the shape memory alloy having a first state and a second state, the first state and the second state being different in at least one dimension;
- and
- an outer component;
- arranging the sleeve, the mating component, the shape memory alloy, and the outer component;
- welding the outer component to the second portion of the sleeve to isolate the shape memory alloy from an external environment, wherein the shape memory alloy transitions in one or more dimensions from the first state to the second state when at least one metal-to-metal seal is formed between the first portion of the sleeve and the mating component;
- and
- subjecting the shape memory alloy to an external stimulus to induce the transition from the first state to the second state.
7 more elements
A downhole component comprising:
- a downhole tool sized to be disposed within a wellbore, the downhole tool comprising at least a sleeve and a mating complementary to the sleeve;
- a shape memory alloy disposed at a surface of the sleeve, the shape memory alloy having a first state and a second state, the first state and the second state being different in at least one dimension, wherein in response to an external stimulus, the shape memory alloy transitions in one or more dimensions from the first state to the second state;
- and
- an outer component, wherein the outer component is welded to the sleeve to isolate the shape memory alloy from an external environment, and the transition of the shape memory alloy to the second state leads to formation of forming at least one metal-to-metal seal between the sleeve and the mating component.
