Wiper Plug

Abstract

Abstract The present invention provides a wiper plug comprising a mandrel and a seal unit disposed about the mandrel wherein the seal unit includes a body and one or more fins extending outwardly from the body. The wiper plug also comprises an anti-extrusion assembly disposed about the mandrel at a leading end of the seal unit. The anti- extrusion assembly is arranged to transition between a first configuration, in which the anti-extrusion assembly is not energized, and a second configuration, in which the anti- extrusion assembly is energized, in response to a pressure applied to an obturating object landed in the wiper plug.
