Abstract: A method for attaching a ring to a borehole tool including locating the ring on the tool, running a weld bead around the ring without alloying the ring to another parent material, the weld causing contraction in a circumferential dimension of the ring. A method for producing a ring for a downhole tool including forming the ring with a weld groove at an outside surface of the ring. A ring for a downhole tool including a ring body, a weld groove formed in an outside surface of the ring. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a ring disposed on the string.

Abstract: A screen and valve system includes a first screen portion including an inner surface and an outer surface. The inner surface defines a first conduit section. A second screen portion includes an inner surface portion and an outer surface portion. The inner surface portion defines a second conduit section. The second screen portion is mechanically joined with the first screen portion such that the first conduit section and the second conduit section form a flow path. A valve member is arranged in the flow path. The valve member includes a a first end segment, a second end segment and an inner surface defining a conduit. First end segment is arranged in the first conduit section without a mechanical connection and the second end segment is arranged in the second conduit section without a mechanical connection. A valve element is slideably arranged in the conduit.

Abstract: A method and system perform flow characteristic control. The system includes a tube inflow control device (ICD) including a tube input port. The tube ICD conveys fluid along an axial length of a tube of the tube ICD. The axial length of the tube controls a drop in pressure of the fluid between the tube input port and a corresponding tube output port. The system also includes a base pipe with an input port coupled to the tube output port of the tube of the tube ICD, wherein the base pipe is configured to convey the fluid to a surface.

Abstract: An apparatus for separating fluids and controlling flow of production fluid includes a support structure configured including a fluid conduit and a tubular assembly disposed at the support structure. The tubular assembly includes an outer tube defining a flow path and having an outer tube inlet in fluid communication with the production fluid, and at least one inner tube disposed eccentrically within the outer tube. The support structure and/or the tubular assembly is configured to cause a centrifugal force on the production fluid that at least partially separates the production fluid into a first fluid portion having a higher concentration of high density fluid than an initial concentration, and a second fluid portion having a higher concentration of the low density fluid than the initial concentration of the low density fluid. One or more inner tubes have an inner tube outlet in fluid communication with the fluid conduit.

Abstract: A screen jacket termination configuration includes a base pipe, a rib disposed at the base pipe, a wire wrapped about the base pipe and rib to form a screen jacket, and a termination strip wrapped about the base pipe and rib and disposed between wraps of the wire. A method for terminating a screen jacket includes disposing a termination strip between adjacent wraps of a screen jacket, the termination strip closing a space between the screen jacket and a base pipe at an end of the screen jacket such that any gap between the termination strip and the base pipe is less than a gauge of the screen jacket.

Abstract: A screen assembly for subsurface systems including a tubular having an outer surface. A first screen portion and a second screen portion extend about the outer surface. The second screen portion is displaced from the first screen portion by a void region. A plurality of weld plugs is mounted about the outer surface of the tubular in the void region. A centralizing ring extends about the tubular at the void region. The centralizing ring extending over each of the first screen portion and the second screen portion and is mechanically joined to the tubular through the plurality of weld plugs.

Abstract: A method of forming a screen assembly includes arranging a first end portion of each of a plurality of rib members into a rib alignment jig, positioning a sleeve about the rib alignment jig with an inner surface of the sleeve abutting the first end portion of each of the plurality of rib members, and resistance welding the sleeve to the first end portion of each of the plurality of rib members.
