Abstract

A wellbore isolation device includes a tubular body having an inner bore formed longitudinally therethrough. A plurality of centralizing arms is radially extendible from the tubular body. At least one slip is radially extendible from the tubular body. A sealing assembly that is radially extendible from the tubular body is also included and disposed between the centralizing arms and the slip. The sealing assembly includes a radially extendible elastomeric sealing surface and an anti-extrusion device having at least two support members coupled to opposite longitudinal ends of the elastomeric sealing surface. An equalizing port is also included which is disposed in the tubular body and permits, when opened, fluidic communication between external the tubular body and the inner bore thereby equalizing the pressure between external the tubular body and the inner bore.
