Circulation flow apertures in a wellbore pipe, tubing, casing or casing liner screen may be selectively closed by an internal pipe sleeve that is formed of a thin, malleable material. One axial end of the sleeve is flared and secured to the inner bore surface of the pipe as by welding or by clamping between the ends of axially adjacent pipe joints joined by a threaded coupling. The remaining length of the sleeve extends along the pipe and over any pipe apertures to form an annular space between the outer cylinder surface of the sleeve and the inner bore surface of the pipe. A perimeter seal element such as an O-ring is placed around the sleeve outer perimeter beyond the apertures in a direction opposite from the sleeve flare. The flow aperture in the pipe is closed by a swaging tool that expands the sleeve against the pipe bore wall sufficiently to close the annulus and compress the O-ring seal against the pipe borewall.

A gravel pack screen assembly has one or more hollow flight augers that a continuous or segmented with multiple upwardly oriented gravel entrances and multiple downwardly oriented gravel exits. The gravel passes through the auger and around any bridge. The auger helps advance the screen into position as well as to centralize it during gravel deposition. The auger protects the screen during run in as well as the internal passages that pass through it due to its structural rigidity. An alternative embodiment features spirally wound tubes with staggered exit locations for better distribution of the gravel.

The invention involves the use of a base pipe perforated only in a specific section under each screen section. Inflow comes through an outer shroud that is optional and goes through the screen material and into an annular space between the screen material and the unperforated base pipe. After traveling longitudinally in that annular space, the flow must go through a restriction that preferably comprises a porous media in a passage defined outside the still unperforated base pipe. After passing through the porous media in a particular screen section, the flow can pass through openings in the base pipe. A surrounding ring preferably protects the porous media during run in and expansion and can also optionally create additional resistance to flow to work in tandem with the porous media. Other flow restricting techniques in place of the porous media are contemplated.

A particulate exculder tool includes a basepipe having one or more retention features; a screen jacket disposed radially outwardly of the basepipe; one or more end housings at the screen jacket; and a deformable element disposed between a portion of the one or more end housings and one or of the one or more retention features and method.

A method and apparatus for manufacturing any given length of a completion filter assembly is described. An outer perforated jacket is assembled over the filter media, which is itself placed over a coarse support screen or drainage layer. In the preferred embodiment, the drainage layer and outer jacket have end rings such that when advanced through a die are pushed together with the filter media in between to effect a seal of the subassembly. The subassembly can then be placed on a support pipe which is perforated, and if metallic, the end rings are welded to the support pipe to complete the assembly. Optionally, many of the components can be made of materials which lend buoyancy to the assembly so that when it is advanced into a long lateral, it will float to assist in its proper positioning.
