A well bore apparatus comprising a first flow joint in a well bore having an annulus, the first flow joint comprising at least one three-dimensional surface defining a hollow body capable of fluid flow, at least one section of the first flow joint body being permeable and at least one section of the first flow joint body being impermeable; a second flow joint in the well bore, the second flow joint comprising at least one three-dimensional surface defining a hollow body capable of fluid flow, at least one section of the second flow joint body being permeable and at least one section of the second flow joint body being impermeable; wherein the annulus is a space between the first and second flow joints and a casing or a formation sand in an uncased well; at least one permeable section of the first flow joint being connected to at least one permeable section of the second flow joint to provide at least one fluid flow path between the first flow joint and the second flow joint; the well bore apparatus allowing flow in accordance with the following scenarios: I. fluid flow through the first flow joint, second flow joint and annulus; and II. a) when the first flow joint is plugged: fluid flow through the second flow joint and the annulus but not through the first flow joint; and b) when the second flow joint is plugged: fluid flow through the first flow joint and the annulus but not through the second flow joint; and c) when the annulus is plugged: fluid flow through the first flow joint and the second flow joint but not through the annulus; and wherein III. when the first flow joint and the annulus are plugged: fluid flow through the second joint past the plugged region into the annulus and the first flow joint; and IV. when the first and second flow joints are plugged: fluid flow through the annulus past the plugged region of the first and second flow joints; and V. when the second joint and the annulus are plugged: fluid flow through the first flow joint past the plugged region of the second flow joint and the annulus. I. fluid flow through the first flow joint, second flow joint and annulus; and II. a) when the first flow joint is plugged: fluid flow through the second flow joint and the annulus but not through the first flow joint; and b) when the second flow joint is plugged: fluid flow through the first flow joint and the annulus but not through the second flow joint; and c) when the annulus is plugged: fluid flow through the first flow joint and the second flow joint but not through the annulus; and wherein a) when the first flow joint is plugged: fluid flow through the second flow joint and the annulus but not through the first flow joint; and b) when the second flow joint is plugged: fluid flow through the first flow joint and the annulus but not through the second flow joint; and c) when the annulus is plugged: fluid flow through the first flow joint and the second flow joint but not through the annulus; and wherein III. when the first flow joint and the annulus are plugged: fluid flow through the second joint past the plugged region into the annulus and the first flow joint; and IV. when the first and second flow joints are plugged: fluid flow through the annulus past the plugged region of the first and second flow joints; and V. when the second joint and the annulus are plugged: fluid flow through the first flow joint past the plugged region of the second flow joint and the annulus.
