Actuation configuration and method

Abstract

An actuation configuration including a baffle having an opening, a plug comprising a plug material extrudable into the opening and compactable therein to hold a differential across the baffle. A borehole system including a housing, a seat in the housing presenting an opening, a plug comprising a plug material extrudable into the opening and compactable therein to hold a differential across seat. A method for treating a borehole including running a plug onto a baffle, extruding plug material into an opening of the baffle, compacting the plug material in the opening to support a target differential pressure across the baffle, and actuating a borehole tool. A method for treating a borehole including running a deformable plug through a restriction, landing the plug on a seat having an opening, compacting material of the deformable plug into the opening to support a differential pressure thereacross, actuating a borehole tool.

What is claimed is: 
     
         1 . An actuation configuration comprising:
 a baffle having a an opening;   a plug comprising a plug material extrudable into the opening and compactable therein to hold a differential across the baffle.   
     
     
         2 . The configuration as claimed in  claim 1  wherein the plug material is an open cell material. 
     
     
         3 . The configuration as claimed in  claim 1  wherein the plug material is a closed cell material. 
     
     
         4 . The configuration as claimed in  claim 1  wherein the baffle includes a plurality of openings therein. 
     
     
         5 . The configuration as claimed in  claim 1  wherein the opening is cylindrical. 
     
     
         6 . The configuration as claimed in  claim 1  wherein the opening is elliptical. 
     
     
         7 . The configuration as claimed in  claim 1  wherein the opening is arc shaped. 
     
     
         8 . The configuration as claimed in  claim 1  wherein the opening includes a wall surface that is roughened. 
     
     
         9 . The configuration as claimed in  claim 1  wherein the opening includes wall surface that has ridges thereon. 
     
     
         10 . The configuration as claimed in  claim 1  wherein the opening includes wall surface that has a threadform thereon. 
     
     
         11 . The configuration as claimed in  claim 1  wherein the opening includes wall surface that has teeth thereon. 
     
     
         12 . A borehole system comprising
 a housing;   a seat in the housing presenting an opening;   a plug comprising a plug material extrudable into the opening and compactable therein to hold a differential across seat.   
     
     
         13 . The system as claimed in  claim 12  wherein the seat further includes a baffle therein. 
     
     
         14 . The system as claimed in  claim 12  wherein the plug material is an open cell material. 
     
     
         15 . The system as claimed in  claim 12  wherein the plug material is a closed cell material. 
     
     
         16 . A method for treating a borehole comprising:
 running a plug onto a baffle;   extruding plug material into an opening of the baffle;   compacting the plug material in the opening to support a target differential pressure across the baffle; and   actuating a borehole tool.   
     
     
         17 . A method for treating a borehole comprising:
 running a deformable plug through a restriction;   landing the plug on a seat having an opening;   compacting material of the deformable plug into the opening to support a differential pressure thereacross;   actuating a borehole tool.   
     
     
         18 . The method as claimed in  claim 17  wherein the actuating comprises shifting of the seat. 
     
     
         19 . The method as claimed in  claim 18  wherein the shifting comprises aligning or misaligning flow structures depending upon whether the flow structures were immediately previous to shifting aligned or misaligned.
