Abstract: A filtering medium for removal of solids from a fluid. A solid filtering matrix contains fluid passages that are made up of a plurality of chambers with connecting channels. The chambers have a greater diameter than the connecting channels.

Abstract: An actuation system and method, the system including a tubular having a passage, and an assembly disposed with the tubular. The assembly includes a degradable restriction, the restriction only partially blocking the passage prior to being degraded. The assembly is configured to receive and prevent further movement of a restrictor through the tubular prior to the restriction being degraded. The assembly is further configured to release the restrictor when the restriction is degraded.

Abstract: An apparatus for use in a wellbore is disclosed that in one non-limiting embodiment includes a tubular having an inside and an outside, a sensor on the outside of the tubular that provides a sensor signal in response to a strain induced in the tubular, and a processor that provides a signal responsive to the sensor signal to operate a device in the wellbore.

Abstract: A downhole system includes a tubular having a plurality of spaced apertures radially extending through a wall of the tubular. A section of the tubular blocking radial fluid flow through the wall between an interior and exterior of the tubular. The section arranged from a first end to a second end of the tubular. A plurality of filter pucks respectively inserted into at least some of the plurality of apertures. The filter pucks each including a body configured for insertion in one of the apertures and a filtering element within each body; and, at least one control or monitoring line arranged on the section. Further is a method of controlling sand in a downhole system.

Abstract: An actuation system and method includes a tubular defining a passage, and an assembly disposed with the tubular. The assembly includes a restriction operatively arranged to receive a restrictor for enabling actuation of the assembly. The restriction includes a degradable material with a protective layer thereon, the degradable material degrading upon exposure to a fluid in the passage and the protective layer isolating the degradable material from the fluid.

Abstract: A shear component for releasably securing a first component to a second component, the shear component comprising a body having a first end, a second end, an outer wall surface, an inner wall surface defining a cavity, a shear plane, and a core disposed within the cavity and in sliding engagement with the inner wall surface of the body. The core comprises a first position in which the core is disposed in alignment with the shear plane, and a second position in which the core is disposed out of alignment with the shear plane. The shear component can be included in a downhole tool to maintain the downhole tool in the run-in or initial position until being compromised by a stimulus.

Abstract: A tubular centralizer is secured to the tubular for run in. The profile for run in is small so that damage to the centralizer is minimized during run in. When the string is in position the centralizer is actuated to change shape or volume to engage the surrounding borehole to centralize the tubular for subsequent operations such as cementing or in the case of screens for gravel packing. The centralizer can be a shape memory material that is initially compressed at above its transition temperature to hold the smaller shape. At the desired location after run in it is brought above the transition temperature and changes back to the original shape or volume to centralize the tubular string. The structure can be spaced ring segments or a cohesive ring structure with an undulating profile or radiating blades to create flow spaces in the annulus where it is deployed for flow of a sealing material or gravel, for example.

Abstract: A subterranean screen system features openings in a base pipe and sleeve sections of a porous material that preferably swells in the borehole to span an annular space around the base pipe. Retainers are mounted to the base pipe in a desired location and mechanically fixated using an internal grip system actuated through the wall of the retainer. A wedging action of slip segments is initiated by an angularly advancing assembly through the wall of the retainer. The retainer can have end rings extending past one or both ends over which the screen sleeve extends. Flat or ridges on the exterior of the retainer or end rings make assembly easier with hand tools to allow for rapid field assembly, if needed. Filtration occurs through the sleeves that abut the borehole wall and into the base pipe openings and to the surface.

The selected fluid is released from the inner mass when the shape memory member is heated to a second temperature.
