Abstract
Methods of sealing tubulars are disclosed herein, which methods may include: providing a patch plug assembly that includes: a shaft; a wedge coupled to the shaft; a slip coupled to the shaft; a plug slidably coupled to the wedge; and a ferrule disposed between the wedge and the plug; pushing the slip against the tubular; pushing the plug against the ferrule after the slip is pushed against the tubular; pushing the ferrule against the wedge after the plug is pushed against the ferrule; and pushing a plug portion of the plug against an inner surface of the tubular.
Claims6
A patch plug assembly for sealing a tubular, comprising:
- a swage having a first swage surface, a second swage surface, and a third swage surface;
- a shaft extending through the swage;
- a wedge coupled to the shaft;
- a slip coupled to the shaft;
- and
- a plug coupled to the shaft, the plug comprising:
- a first protrusion disposed around a portion of the first swage surface;
- a second protrusion disposed around a portion of the first swage surface, wherein the first protrusion and the second protrusion share a tangent line extending at an angle to a central axis of the plug;
- and
- an inner plug surface abutted against a portion of the first swage surface, wherein when the inner plug surface is abutted against a portion of the third swage surface, the inner plug surface extends axially at an angle to the central axis;
- wherein when the first protrusion and the second protrusion are disposed around a portion of the third swage surface, the tangent line is parallel to the central axis of the plug.
