Abstract

A screen device includes a foam body having a passageway that extends longitudinally through the foam body, the foam body has an open cell structure such that at least two surfaces of the foam body are in fluidic communication with one another through the foam body.

First claim

What is claimed:

1. A screen device comprising a foam body having a passageway and a void that both extend longitudinally through the foam body, the foam body having an open cell structure such that at least two surfaces of the foam body are in fluidic communication with one another through the foam body, the passageway and the void each having separate perimetrically continuous walls formed in the foam the perimetrically continuous wall of the passageway defining a non-fluid permeable barrier.

2. The screen device of claim 1 , wherein one of the at least two surfaces defines a wall of the void in the foam body.

3. The screen device of claim 2 , wherein the void is receptive to a perforated tubular.

4. The screen device of claim 2 , wherein the passageway is helically spiraled about the void.

5. The screen device of claim 2 , wherein the foam body surrounds the void and an inside of the void and an outside of the foam body are in fluidic communication through the open cell structure.

6. The screen device of claim 1 , wherein a longitudinal axis of the passageway is substantially parallel to a longitudinal axis of the foam body.

7. The screen device of claim 1 , wherein the foam body defines a tubular.

8. The screen device of claim 1 , wherein the foam body is positioned on a downhole tool string and the passageway forms a conduit receptive to a line.

9. The screen device of claim 8 , wherein the line is at least one of a hydraulic line, an electric line, a fiber optic cable and a chemical injection line.

10. The screen device of claim 1 , wherein the passageway and the void are parallel to one another yet are not coaxial.

11. A downhole screen, comprising:
a foam body having a passageway and a void extending therethrough, the foam body defining perimetrically continuous walls of both the passageway and the void, the foam body having an open cell structure providing fluidic communication between an outer surface of the foam body and an inside of the void;
a tubular having a wall with perforations therethrough extending longitudinally through the void; and
a conduit extending longitudinally through the passageway, wherein each of the perimetrically continuous walls defining the passageway and the conduit being permeable to fluid.

12. The downhole screen of claim 11 , wherein the conduit helically surrounds the tubular.

13. The downhole screen of claim 11 , wherein an axis of the conduit is substantially parallel with an axis of the foam body.

14. The downhole screen of claim 11 , further comprising a line running through the conduit.

15. The downhole screen of claim 14 , wherein the line is fixedly attached to the foam body.

16. The downhole screen of claim 14 , wherein the line is slidably engaged with the foam body.

17. The downhole screen of claim 14 , wherein the line is one of a hydraulic control line, an electric line, a fiber optic cable and a chemical injection line.

18. The downhole screen of claim 11 , wherein the foam body is constructed of resins, polyolefins, polyurethanes, polyvinylchlorides, metals, ceramics and combinations thereof.

19. A screen device comprising a foam body having a passageway and a void that both extend longitudinally through the foam body, the foam body having an open cell structure such that at least two surfaces of the foam body are in fluidic communication with one another through the foam body, the passageway and the void each having separate perimetrically continuous walls formed in the foam, wherein the passageway is entirely surrounded by the foam body.
