Abstract

A shape memory material element configuration. The element includes a shape memory material element, and a capillary line extending to the element, and positioned to apply an activation fluid to the element.

Claims (27)

1. A shape memory material element configuration comprising:

a shape memory material element having a remembered shape, the shape memory material including a manifold within the element configured to distribute activation fluid within the element; and

a capillary line extending to the element and connected to the manifold to apply an activation fluid through the capillary line to the manifold, the activation fluid being distributed within the element and triggering the element to passively assume the remembered shape.

2. The configuration as claimed in claim 1 wherein the shape memory material is a shape memory polymer.

3. The configuration as claimed in claim 1 wherein the element is permeable.

4. The configuration as claimed in claim 1 wherein the line extends into the element.

5. The configuration as claimed in claim 4 wherein a portion of the line extending into the element includes a plurality of orifices in the line.

6. The configuration as claimed in claim 4 wherein a portion of the line extending into the element is porous to activation fluid.

7. The configuration as claimed in claim 1 , further comprising a manifold in fluid connection with the line.

8. The configuration as claimed in claim 7 wherein the manifold is a separate structure from the element but disposed in the element.

9. The configuration as claimed in claim 7 wherein the manifold is a created within the element.

10. The configuration as claimed in claim 7 wherein the manifold is an activation fluid distribution pathway within the element.

11. The configuration as claimed in claim 10 wherein the pathway is a branching pathway.

12. The method as claimed in claim 10 further including regulating the volume of activating fluid such that the volume is sufficient to activate the element while avoiding excess activating fluid escape to an environment outside of the element.

13. The method as claimed in claim 10 further including contacting a borehole wall with the element and filtering fluid passing between a formation surrounding the borehole wall and an inside diameter surface of the element.

14. The configuration as claimed in claim 1 wherein the element expands upon exposure to the activation fluid.

15. A method for deploying a shape memory material element configuration as claimed in claim 1 comprising:

injecting a volume of activating fluid through the capillary line; and

infusing the shape memory material with the activating fluid.

16. A method for deploying a shape memory material element configuration as claimed in claim 1 comprising:

preparing a volume of activating fluid needed to deploy the element to be supplied to the element; and

supplying the volume to the element without dilution or loss of the volume.

17. A wellbore system comprising:

a borehole in a subsurface formation;

a string in the borehole; and

a shape memory material element configuration as claimed in claim 1 disposed within or as a part of the string.

18. The configuration as claimed in claim 1 wherein the manifold is a separate structure from the element but disposed in the element.
