Abstract
A downhole tool includes a mandrel and a deformable seal positioned around the mandrel to hold overpressure. An extrusion limiter is positioned around the mandrel, and adjacent to the deformable seal. The extrusion limiter includes a body, and grooves formed into the body that separate fins. The grooves have at least one portion formed at an acute angle relative to a circumferential line centered on the central axis of the extrusion limiter body. After the bending of the fins that occurs in use of the extrusion limiter, the gaps left by the grooves between the fins may be smaller than gaps left by straight grooves that are perpendicular to circumferential lines centered on the central axis of the body. The smaller gaps reduce extrusion of the deformable seal.
