Tubular anchoring system and a seat for use in the same
View Patent ↗A tubular anchoring system includes a first frustoconical member. Slips in operable communication with the first frustoconical member are radially expandable into an 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 is radially expandable into sealing engagement with the structure in response to longitudinal movement relative to a second frustoconical member. A seat in operable communication with the first frustoconical member having a surface configured to be sealingly engagable with a plug runnable thereagainst, is configured and positioned relative to the collar to aid the seat in maintaining a radially expanded configuration against a pressure differential formed across the seat when plugged.
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.
2. The tubular anchoring system of claim 1 , wherein the seat and the first frustoconical member are one piece.
3. The tubular anchoring system of claim 1 , further comprising a seal in operable communication with the collar configured to seal the collar to the structure when radially compressed therebetween.
4. The tubular anchoring system of claim 3 , wherein the seal is polymeric.
5. The tubular anchoring system of claim 1 , wherein the collar, the seat and the first frustoconical member are one piece.
6. The tubular anchoring system of claim 1 , wherein the surface of the seat is positioned in a direction longitudinally downstream of the collar in a direction defined by fluid flow that urges a plug against the surface of the seat.
7. The tubular anchoring system of claim 6 , wherein pressure built against the seat when plugged urges the collar radially outwardly.
