A method and apparatus are provided for use on a subterranean well gravel packing conduit. The apparatus incorporates a cylindrically shaped inner tubular member having an interior wall and an exterior wall. A fluid flow passageway is defined within the interior wall of the tubular member and fluid flow passage means extends from the interior of the tubular member through the exterior wall and communicates with the fluid flow passageway. In a preferred embodiment, an outer fluid-porous means, or particulate restricting means is carried around the exterior wall of the tubular member having its interior facing the tubular member. Wire mesh means are disposed between the exterior wall of the tubular member and the interior of the particulate-restricting means, and passing across the fluid flow passage means, with fluid flow openings therethrough, to enable fluid passing through the particulate restricting means and the wire mesh means to be filtered to prevent solids of a predeterminable size from passing into the fluid flow passage means, to the top of the well. The device may be utilized in a number of well completion hook-ups, such as in non-vertical completion apparatuses and methods.
