Abstract

A method of making a downhole swellable seal with a passageway therethrough includes, perimetrically surrounding a first tubular with a first substantially nonswellable material, perimetrically surrounding at least one second tubular with a second substantially nonswellable material, positioning the at least one second tubular adjacent the first tubular, perimetrically surrounding the first tubular and the at least one second tubular with a swellable material, curing the first substantially nonswellable material, curing the second substantially nonswellable material, and curing the swellable material.

First claim

What is claimed is:

1. A method of making a downhole swellable seal with a passageway therethrough, comprising:
perimetrically surrounding a first tubular with a first substantially nonswellable material;
perimetrically surrounding at least one second tubular with a second substantially nonswellable material;
positioning the at least one second tubular adjacent the first tubular;
perimetrically surrounding the first tubular and the at least one second tubular with a swellable material;
curing the first substantially nonswellable material arranged on the first tubular;
curing the second substantially nonswellable material arranged on the second tubular; and
curing the swellable material.

2. The method of making the downhole swellable seal with a passageway therethrough of claim 1 , further comprising:
withdrawing the at least one second tubular from the second substantially nonswellable material;
leaving a void with perimetrically continuous walls in the second substantially nonswellable material; and
inserting a third tubular into the void.

3. The method of making the downhole swellable seal with a passageway therethrough of claim 2 , further comprising connecting the third tubular to the at least one second tubular prior to withdrawing the at least one second tubular.

4. The method of making the downhole swellable seal with a passageway therethrough of claim 1 , further comprising sealing the first tubular to the first substantially nonswellable material and sealing the at least one second tubular to the second substantially nonswellable material.

5. The method of making the downhole swellable seal with a passageway therethrough of claim 1 , further comprising applying a release agent to the at least one second tubular prior to the surrounding with substantially nonswellable material.

6. The method of making the downhole swellable seal with a passageway therethrough of claim 1 , further comprising damming the swellable material with at least one of the substantially nonswellable materials.

7. The method of making the downhole swellable seal with a passageway therethrough of claim 6 , further comprising sealably attaching a mechanical device to the at least one second tubular and to the substantially nonswellable material that is damming the swellable material.

8. The method of making the downhole swellable seal with a passageway therethrough of claim 7 , wherein the sealably attaching of the mechanical device to the at least one second tubular is a metal-to-metal seal.

9. The method of making the downhole swellable seal with a passageway therethrough of claim 7 , wherein the sealably attaching includes immobilizing the at least one second tubular with respect to the substantially nonswellable material that is damming the swellable material.

10. The method of making the downhole swellable seal with a passageway therethrough of claim 1 , further comprising perimetrically surrounding at least one of the first substantially nonswellable material and the second substantially nonswellable material with the swellable material.
