Abstract
A limit collar includes a limit component coupled to a surface of a wellbore tubular; and an interface component engaging the limit component. The interface component may include an extension, and wherein at least one surface of the extension is coupled to the limit component. The extension may also include a side extension.
Claims23
A limit collar comprising:
- a limit component coupled to a surface of a wellbore tubular;
- and
- an interface component engaging the limit component, wherein the interface component comprises a material with a compressive strength greater than that of a material used to form the limit component.
A limit collar comprising:
- a limit component coupled to a surface of a wellbore tubular;
- and
- an interface component engaging the limit component, wherein the limit collar comprises a plurality of portions, and wherein each portion does not extend around the perimeter of the wellbore tubular.
A method comprising:
- providing a limit collar disposed on a wellbore tubular and a first component slidingly engaged on the wellbore tubular, wherein the limit collar comprises:
- a limit component coupled to a surface of the wellbore tubular;
- and
- an interface component engaging the limit component, wherein the interface component comprises a material with a compressive strength greater than that of a material used to form the limit component;
- and
- conveying the wellbore tubular within a wellbore, wherein the first component is retained on the wellbore tubular due to the engagement of the first component with the interface component.

A method comprising:
- providing a limit collar disposed on a wellbore tubular and a first component slidingly engaged on the wellbore tubular, wherein the limit collar comprises:
- a limit component coupled to a surface of the wellbore tubular, wherein the limit component comprises a polymer, and wherein the polymer comprises a cross-linked polymer, a polyolefin, a cross-linked polyolefin, or any combination thereof, and
- an interface component engaging the limit component;
- and
- conveying the wellbore tubular within a wellbore, wherein the first component is retained on the wellbore tubular due to the engagement of the first component with the interface component.
2 more elements
A method comprising:
- providing a wellbore tubular;
- and
- forming a limit collar on a first surface portion of the wellbore tubular, wherein the limit collar comprises:
- a limit component coupled to the first surface portion of the wellbore tubular;
- and
- an interface component engaging the limit component,
- wherein forming a limit collar on the first surface portion comprises:
- disposing a mold about the interface component and the first surface portion;
- and
- injecting a composite material into a space between the mold and the first surface portion to form the limit component.
7 more elements
A method comprising:
- providing a wellbore tubular;
- and
- forming a limit collar on a first surface portion of the wellbore tubular, wherein the limit collar comprises:
- a limit component coupled to the first surface portion of the wellbore tubular;
- and
- an interface component engaging the limit component,
- wherein forming a limit collar on the first surface portion comprises:
- disposing a polymer material about the interface component and the first surface portion;
- and
- shrinking the polymer material to form the limit collar by applying heat to the polymer.
7 more elements
A method comprising:
- providing a wellbore tubular;
- and
- forming a limit collar on a first surface portion of the wellbore tubular, wherein the limit collar comprises:
- a limit component coupled to the first surface portion of the wellbore tubular;
- and
- an interface component engaging the limit component,
- wherein forming a limit collar on the first surface portion comprises:
- thermally spraying a composition comprising a metal onto the first surface portion and the interface component to form the limit collar.
