Abstract

An inverted seal including a disintegrable body, one or more inside dimension seals disposed in the body. A method for removing an inverted seal from a downhole environment including exposing the body of the inverted seal to a condition to which it is responsive, disintegrating a portion of the body. A method for deploying a conventional seal after an inverted seal in a borehole including 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.

First claim

What is claimed is:

1. A method for deploying a conventional seal after an inverted seal in a borehole comprising:
positioning an inverted seal in a disintegrable body;
arranging the inverted seal supported in the disintegrable body in a downhole location;
utilizing the inverted seal for its intended purpose;
removing at least a portion of the disintegrable body supporting the inverted seal;
radially displacing the seal after removing the portion of the disintegrable body; and
running a conventional seal further downhole of the location of the inverted seal.

2. The method as claimed in claim 1 comprising:
setting the conventional seal.

3. The method as claimed in claim 1 wherein the removing is disintegrating.

4. The method as claimed in claim 1 wherein the removing is forcible.
