that fluid is able to pass therethrough in either direction between the open cell structured foam 31 and the conduit 26 an embodiment wherein the walls 28 b are permeable permits treatments therethrough for example chemical injection for treating the open cell structured foam 31 or the earth formation 12 such as for acid treatments or corrosion inhibitor treatments the anticipated treatments and environmental conditions in which the screen device 10 will be operational will influence materials used to construct the foam body 13 additional considerations include whether or not the foam body 13 needs to be deformable or not as such materials contemplated for the foam body 13 include resins polyolefins polyurethanes polyvinylchlorides metals ceramics and combinations thereof regardless of the material of the foam body 13 running the line 22 through the conduit 26 provides a means of communicating through the screen device 10 the line 22 can be one or more of several lines commonly used in downhole completion applications such as a hydraulic line an electric line a fiber optic cable and a chemical injection line for example referring to fig2 the line 22 can be free to slide within the conduit 26 by sizing the line 22 and the conduit 26 with an annular space 54 therebetween alternately the line 22 can be fixedly attached to the conduit 26 as illustrated in fig3 one way to attach the line 22 to the conduit 26 is to surround the line 22 with a foam 58 that is radially small enough to.
