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.

An apparatus for use on a subterranean well gravel packing conduit, comprising: a cylindrically shaped inner tubular member having an interior wall and an exterior wall; a fluid flow passageway defined within the interior wall of said tubular member; fluid flow passage means extending from the interior of said tubular member through the exterior wall of said tubular member and in communication with said fluid flow passageway; a fluid-porous particulate-restricting means carried around the exterior wall of said tubular member and having its interior facing the tubular member; wire mesh means disposed between the exterior wall of said tubular member and the interior of said particulate-restricting means and passing across said fluid flow passage means, and having fluid flow openings therethrough, said wire mesh means having inner and outer wrapping means interwoven between one another, at least one of said inner tubular members and said particulate restricting means being secured at at least one of its ends to the subterranean well gravel packing conduit, whereby fluid passing through said particulate restricting means and said wire mesh means is filtered to prevent solids of a pre-determinable size from passing into said fluid flow passage means and into said fluid flow passageway through the subterranean well gravel packing conduit. A method of gravel packing subterranean oil or gas well comprising the steps of: (1) introducing into said well a subterranean well conduit having disposed thereon at least one well packer apparatus and at least one gravel packing apparatus, said gravel packing apparatus comprising: a cylindrically shaped inner tubular member having an interior wall and an exterior wall; a fluid flow passageway defined within the interior wall of said tubular member; fluid flow passage means extending from the interior of said tubular member through the exterior wall of said tubular member and in communication with said fluid flow passageway; a fluid-porous particulate-restricting means carried around the exterior wall of said tubular member and having its interior facing the tubular member; wire mesh means disposed between in the exterior wall of said tubular member and the interior of said particulate-restricting means and passing across said fluid flow passage means, and having fluid flow openings therethrough, said wire mesh means having inner and outer wrapping members interwoven between one another, at least one of said inner tubular members and said particulate restricting means being secured at at least one of its ends to the subterranean well gravel packing conduit, whereby fluid passing through said particulate restricting means and said wire mesh means is filtered to prevent solids of a pre-determinable size from passing into said fluid flow passage means and into said fluid flow passageway through the subterranean well gravel packing conduit; (2) placing said gravel packing apparatus adjacent a production zone in said well; (3) setting said well packer ; and (4) introducing a carrier fluid containing a particulate matter into said well conduit for placement of said particulate matter exterior of said well conduit and adjacent said production formation.
