Abstract:
1. A tubular anchoring system comprising: a first frustoconical member; slips in operable communication with the first frustoconical member being radially expandable into anchoring engagement with a structure in response to longitudinal movement relative to a frustoconical surface of the first frustoconical member; a collar in operable communication with the first frustoconical member being radially expandable into sealing engagement with the structure in response to longitudinal movement relative to a second frustoconical member the second frustoconical member being retrievable after expansion of the collar has taken place while the collar remains radially expanded into sealing engagement with the structure; and a seat in operable communication with the first frustoconical member having a surface configured to be sealingly engagable with a plug runnable thereagainst, the seat being configured and positioned relative to the collar to aid the collar in maintaining a radially expanded configuration against a pressure differential formed across the seat when plugged.
