Abstract

A plug assembly includes a cone assembly, a sealing ring, a slip device of a plurality of blades, a plurality of spaces defined by adjacent blades, a plurality of support lugs, and a setting ring. The setting ring moves from a first setting distance relative to the cone assembly to a second setting distance closer to the cone assembly to radially expand the sealing ring, slip device, and spaces to install the plug assembly at the downhole location. The support lugs are aligned with the spaces to prevent extrusion of the sealing ring into the spaces and radially expand when the blades and spaces radially expand. The support lugs can be separate from each other, overlap, or interlock. The method of installation includes radially expanding the sealing ring, when the sealing ring is separated from the spaces formed by the blades of the slip device.
