Debris control arrangement for a whipstock and method

Abstract

A whipstock includes a whipstock body having a diverter face; and a swellable material disposed about the whipstock body and configured, positioned and dimensioned to interact with an inside dimension of a borehole in which the whipstock is run and method.

1 . A whipstock comprising:
 a whipstock body having a diverter face; and   
     a swellable material disposed about the whipstock body and configured positioned and dimensioned to interact with an inside dimension of a borehole in which the whipstock is run. 
   
   
       2 . The whipstock as claimed in  claim 1  wherein the swellable material is toroidally shaped. 
   
   
       3 . The whipstock as claimed in  claim 1  wherein the swellable material is band shaped. 
   
   
       4 . The whipstock as claimed in  claim 1  wherein the swellable material covers the whipstock body exclusive of the diverter face. 
   
   
       5 . The whipstock as claimed in  claim 1  wherein the swellable material is responsive to at least one of water, oil and methane. 
   
   
       6 . The whipstock as claimed in  claim 1  wherein the swellable material is disposed parametrically about the diverter face. 
   
   
       7 . A method for preserving whipstock mobility comprising:
 applying a swellable material to a whipstock body;   running the whipstock in a wellbore; and   exposing the swellable material to a swelling fluid.   
   
   
       8 . The method for preserving whipstock mobility as claimed in  claim 7  wherein the applying is toroidally. 
   
   
       9 . The method for preserving whipstock mobility as claimed in  claim 7  wherein the applying is in a band. 
   
   
       10 . The method for preserving whipstock mobility as claimed in  claim 7  wherein the applying is complete exclusive of a diverter face of the whipstock. 
   
   
       11 . The method for preserving whipstock mobility as claimed in  claim 7  wherein the applying is parametrically about a diverter face of the whipstock.
