Disintegrable inverted seal

Abstract

An inverted seal includes a disintegrable body; one or more inside dimension seals disposed in the body. A method for deploying a conventional seal after an inverted seal in a borehole.

1 . An inverted seal comprising:
 a disintegrable body;   one or more inside dimension seals disposed in the body.   
     
     
         2 . The inverted seal as claimed in  claim 1  wherein the body comprises a controlled electrolytic material. 
     
     
         3 . The inverted seal as claimed in  claim 1  wherein the body is disintegrable in response to downhole fluids. 
     
     
         4 . The inverted seal as claimed in  claim 1  wherein the body is disintegrable in response to fluids delivered to the inverted seal. 
     
     
         5 . The inverted seal as claimed in  claim 1  wherein the body is entirely disintegrable. 
     
     
         6 . The inverted seal as claimed in  claim 1  wherein the body is partially disintegrable. 
     
     
         7 . The inverted seal as claimed in  claim 1  wherein the body includes a portion that is disintegrable and portion that is durable. 
     
     
         8 . The inverted seal as claimed in  claim 7  wherein the durable portion is radially outwardly disposed of the disintegrable portion. 
     
     
         9 . A method for removing an inverted seal from a downhole environment comprising:
 exposing the body of the inverted seal of  claim 1  to a condition to which it is responsive;   disintegrating a portion of the body.   
     
     
         10 . A method for deploying a conventional seal after an inverted seal in a borehole comprising:
 positioning an inverted seal in a downhole location;   utilizing the inverted seal for its intended purpose;   removing at least a portion of a body of the inverted seal;   running a conventional seal further downhole of the location of the inverted seal.   
     
     
         11 . The method as claimed in  claim 10  comprising:
 setting the conventional seal. 
 
     
     
         12 . The method as claimed in  claim 10  wherein the removing is disintegrating. 
     
     
         13 . The method as claimed in  claim 10  wherein the removing is forcible. 
     
     
         14 . The method as claimed in  claim 10  wherein the removing is cutting. 
     
     
         15 . The method as claimed in  claim 10  wherein the removing is scraping.
