High expansion downhole packer
First Claim
1. An expandable apparatus for filling a space downhole in a wellbore, comprising:
- an expandable body having a hollow interior which defines an open flow path through said body;
a deformable material within said hollow interior for at least partially obstructing said flow path when said body is moved into said wellbore, wherein said deformable material is displaceable to expand said body into the space and to open said flow path through said body.

Abstract
An expandable apparatus for sealing a space downhole in a wellbore. The apparatus has an expandable body having a hollow interior for defining an open flow path. A deformable material within the hollow body interior partially obstructs the flow path when the body is run into the wellbore, and the deformable material is displaceable to expand the body into the downhole space and to open the body flow path. Such material can be displaced with a setting tool or with mechanical movement of the body components. A second body section can be moved relative to a first body section to displace the deformable material from the body interior. The second body section can initially be discontinuous with the first body section to permit installation through narrow wellbore spaces and can be connected downhole to create a unitary body structure.

9. An apparatus for filling a space downhole in a wellbore, comprising:
-
a first body section having a hollow interior about a longitudinal axis through said first body section which defines an open flow path through said body section; a second body section moveable relative to said first body section and having a hollow interior about said longitudinal axis which defines an open flow path through said second body section; a deformable sheath having a first end attached to said first body section and having a second end attached to said second body section, wherein said sheath at least partially defines an interior volume proximate to said first body section and said second body section; and a deformable material within said interior volume for moving said sheath into the downhole wellbore space when the sheath second end moves relative to said sheath first end, wherein said second body section is attachable to said first body section after said deformable material is displaced. - View Dependent Claims (10, 11)

12. An apparatus for filling a space downhole in a wellbore, comprising:
-
a first body section having a hollow interior about a longitudinal axis through said first body section which defines an open flow path through said first body section; a second body section moveable relative to said first body section; a deformable sheath between said first body section and said second body section for at least partially defining an interior volume proximate to said first body section and to said second body section; a deformable material within said interior volume for moving said sheath into the downhole wellbore space when said second body section moves relative to said first body section, wherein said deformable material is displaceable to open said flow path through said first body section; and a connector for attaching said second body section to said first body section after said deformable material is displaced from said interior volume. - View Dependent Claims (13, 14, 15, 16)
