A rotary valve including a port housing, a port, an axially actuated rotary sleeve disposed within the port housing, the sleeve having a plurality of apertures in fluid communication with the port; and an insert disposed within the sleeve, the insert having an opening, the sleeve being rotatable to align one of the plurality of apertures with the opening. A rotary valve including a port housing, having a port, an axially actuated rotary sleeve disposed within the port housing, the sleeve having an aperture; and an insert disposed within the sleeve, the insert having a plurality of openings of distinct size from one another, the aperture of the sleeve being selectively alignable with one of the plurality of openings.

Rotary valve and system

A downhole tool includes a tubular having an outer surface, an inner surface, a recess extending from the inner surface toward the outer surface, and an opening extending from the outer surface to the recess. A hydraulic passage extends through the tubular. The hydraulic passage includes an inlet, a first and a second branch. The second branch is fluidically exposed at the inner surface. A piston is arranged in the recess. A locking ring is arranged radially inwardly of the piston and a member is arranged in the tubular spaced from the inner surface. Application of hydraulic pressure in the first branch urges the piston radially inwardly clamping the locking ring against the member and application of hydraulic pressure in the second branch urges the member axially in a first direction relative to the tubular.

An indexing valve system includes a tubular having an inner surface portion defining a passage portion, a first plurality of indexing components provided on the inner surface and a second plurality of indexing components provided on the inner surface portion. A valve sleeve is arranged in the passage portion. The valve sleeve includes a first plurality of indexing elements that selectively engage with the first plurality of indexing components, a second plurality of indexing elements that selectively engage with the second plurality of indexing components, and an inner surface section defining a passage section. The inner surface section includes a plurality of indexing step members. An insert extends into the passage section. The insert includes an outer surface supporting an indexer that selectively engages with the plurality of indexing step members to shift the valve sleeve between the first plurality of indexing components and the second plurality of indexing components.

Indexing tool system for a resource exploration and recovery system

A diffuser assembly has pairs of split rings rotationally locked to each other in an alternating array with other pairs of split rings where adjacent pairs are responsive to pressure differential to be biased toward a sliding sleeve or the surrounding housing in an alternating pattern. The split rings are made to have an interference initial fit to the sleeve or housing and the splits on adjacent rings are offset while a relation of a projection to a depression between adjacent rings prevents relative rotation to keep the desired circumferential offset in the splits between adjacent rings. End tapers can bias adjacent pairs in opposed directions responsive to applied differential pressure. The rings are preferably metallic and can have a coating to facilitate relative sliding and enhance durability.

Multi-component diffuser assembly

An insert device can straddle an existing production string port into the annulus such as through an open sliding sleeve so that annulus access into the production string is available. An injection string is associated with the insert to allow placement of the injection fluid at the desired location even if that location is below an isolation packer. The port can be part of an existing ported sub such as a sliding sleeve. Alternatively, the port can be created at a desired location and the insert supported with an anchor so that spaced seals straddle the port that is created to allow injection access from the annulus into the production tubing. The produced fluids pass around the injection tubing and through the insert body to get to the surface. The insert can be removed if needed.
