= DOWNHOLE PLUG =

'''Abstract''':
a downhole plug, has an inner mandrel and a sealing assembly carried on and surrounding an outer surface of the inner mandrel. the sealing assembly is positioned between a lower support downstream of the sealing assembly and a setting shoulder upstream of the sealing assembly. the sealing assembly is activated from a deactivated state to a sealing state by causing the setting shoulder and the lower support to apply a compressive force to the sealing assembly such that an elastomeric seal extrudes outward into sealing engagement with an inner surface of a tubular. the lower support has a series of expandable segments mounted by a frangible connection, such that, as the compressive force is applied, the expandable segments break away from the lower support and move outward into engagement with the inner surface of the tubular.
