Abstract
A compression assembly () for actuating packing elements of a through tubing bridge plug in a casing string of a wellbore. The compression assembly () includes a support assembly () and an anti extrusion assembly (). The support assembly () has a running configuration in which link arm assemblies are substantially longitudinally oriented and an operating configuration in which short arms () are pivoted relative to long arms () of link arm assemblies such that the short arms () form a support platform. The anti extrusion assembly () is operably associated with the support assembly (). The anti extrusion assembly () has a running configuration in which petals () are substantially perpendicular to a base member () and nested relative to one another and an operating configuration in which the petals () are radially outwardly disposed substantially filling gaps between the short arms ().
