Abstract
A technique facilitates use of frangible components. The frangible components may comprise components of a gripping tool, e.g. anchor, used in a variety of applications, including well related applications. The tool is provided with a plurality of gripping members which each comprise a frangible structure. The gripping members may be selectively deployed to provide the desired gripping within a tubular structure, e.g. an open wellbore or well casing. The frangible structure in each gripping member is designed to break down into smaller portions after being exposed to a predetermined input, thus facilitating removal of the tool from the tubular structure.
Claims19
A device for use in a wellbore, comprising:
- an anchoring tool comprising a plurality of slips, each slip having a base portion and a wall gripping portion, the base portion being formed with a frangible structure which breaks down into smaller portions following a predetermined input in the wellbore, wherein the base portion is formed of a first material and the gripping portion is formed of a second material, wherein further the frangible structure comprises at least one notch designed to fracture the base portion when placed under a predetermined load.
A system for use in a well, comprising:
- a tubing string;
- and
- a tool mounted to the tubing string, the tool comprising gripping members oriented to grip a surrounding wall located in the well, the gripping members being formed with a frangible structure, the frangible structure breaking down into smaller portions upon a predetermined input, wherein each gripping member comprises a base portion and a gripping portion, the gripping portion being formed of a harder material than the base portion, wherein further the frangible structure comprises at least one notch designed to fracture the base portion when placed under a predetermined load.
A method of providing temporary gripping capability in a wellbore, comprising:
- providing a well tool with a plurality of gripping members each formed with a frangible structure;
- creating at least one notch in the frangible structure designed to fracture the frangible structure when placed under a predetermined loading;
- deploying the well tool in a well;
- operating the plurality of gripping members to grip a surrounding wall;
- and
- exposing the frangible structure in each gripping member to an input causing breakdown of the frangible structure into smaller portions.
