Abstract: A downhole tool for use in a well has a mandrel with an expandable sealing element disposed thereabout. The mandrel has a head portion threadedly connected thereto. A shoulder in the head portion and an upper end of the mandrel define an annular space. A sleeve with a bore therethrough may be positioned in the annular space. The head portion may be removed and a solid plug installed so that it fits within the annular space and so that the downhole tool will act as a bridge plug. The downhole tool has slip rings made up of a plurality of individual slip segments that are adhesively bonded to one another at the sides thereof.

Abstract: A downhole tool has a mandrel with a sealing element disposed thereabout. The sealing element is movable from an unset position to a set position in which the sealing element engages the well. Extrusion limiters are positioned at the ends of the sealing element. The extrusion limiters have first and second layers and the first and second layers are different materials. The second layer may be made up of a plurality of discs. At least one of the discs may be a disc with an irregularly shaped outer peripheral edge and a generally circular inner peripheral edge. A plurality of the discs with the irregularly shaped outer edge may be stacked and may be stacked with a generally circular or ring-shaped segmented disc. The first and second layers are stacked and then molded into a final shape for placement at the ends of the sealing element.

Abstract: An apparatus for use in a wellbore is provided. The apparatus comprises a mandrel, a sealing element carried on the mandrel, the sealing element being radially expandable from a first run-in diameter to a second set diameter in response to application of axial force on the sealing element, and an extrusion limiting assembly carried on the mandrel and proximate the sealing element. The extrusion limiting assembly comprises a plurality of separate segments and a first circumferential band that retains the plurality of segments in a ring shape and substantially covers an outer circumferential surface of the plurality of segments while in a run-in condition of the apparatus.
