Abstract
A repairable seal assembly for deployment at a wellbore includes an elongate body, a first seal carried by the elongate body and configured to seal against an adjacent surface, and a transitional component carried by the elongate body. The transitional component is adjustable from a first configuration in which the transitional component defines a gap between the transitional component and the adjacent surface to a second configuration in which the transitional component contacts the adjacent surface to form a second seal at the adjacent surface.
Claims23
A repairable seal assembly for deployment at a wellbore, the repairable seal assembly comprising:
- an elongate body;
- a first seal carried by the elongate body and configured to seal against an adjacent surface;
- and
- a transitional component carried by the elongate body and being adjustable from a first configuration in which the transitional component defines a gap between the transitional component and the adjacent surface to a second configuration in which the transitional component contacts the adjacent surface to form a second seal at the adjacent surface.
A completion system installed at a wellbore, the completion system comprising:
- a tubular component providing an interface;
- and
- a repairable seal assembly positioned adjacent the interface, the seal assembly comprising:
- an elongate body,
- a first seal carried by the elongate body and configured to seal against the interface, and
- a transitional component carried by the elongate body and being adjustable from a first configuration in which the transitional component defines a gap between the transitional component and the interface to a second configuration in which the transitional component contacts the interface to form a second seal at the interface.
A seal assembly for deployment at a wellbore, the seal assembly comprising:
- an elongate body;
- and
- a transitional component carried by the elongate body and being adjustable from a first configuration in which the transitional component defines a gap between the transitional component and an adjacent surface to a second configuration in which the transitional component contacts the adjacent surface to form a seal at the adjacent surface.
A method of sealing a tubing system installed at a wellbore, the method comprising:
- forming a first seal between a sealing element carried by an elongate body and a surface adjacent the elongate body;
- determining a failure of the first seal at the surface;
- adjusting a transitional component carried by the elongate body from a first configuration in which the transitional component defines a gap between the transitional component and the surface to a second configuration in which the transitional component contacts the surface;
- and
- forming a second seal between the transitional component in the second configuration and the surface.
