Abstract
A tubular anchoring system includes a frustoconical member and a sleeve with at least one first surface that is radially alterable in response to longitudinal movement of the frustoconical member relative to the sleeve. The at least one first surface is engagable with a wall of a structure positioned radially thereof to maintain position of at least the sleeve relative to the structure when engaged therewith. A seal with at least one second surface is radially alterable in response to longitudinal movement of the frustoconical member relative to the seal, and a seat is in operable communication with the frustoconical member having a land which is sealingly engagable with a removable plug runnable thereagainst. The land is longitudinally displaced relative to the sleeve in an upstream direction defined by direction of flow that urges the plug thereagainst.
