A valve apparatus comprises a valve body defining a flow path therethrough, a valve member mounted within the valve body, and an actuator assembly mounted internally within the valve body. The actuator assembly comprises a piston bore and piston member defining a piston chamber therebetween, wherein at least one of the piston bore and piston member is engaged or associated with the valve member such that the valve member is moveable in accordance with fluid pressure within the piston chamber to selectively occlude the flow path.

Piston actuated valve apparatus

A screen assembly, such as a downhole/sand screen assembly, comprising first and second screen portions or screens longitudinally coupled together, wherein there is provided a fluid flow path between the first and second screen portions or screen. Optionally, the first and second sleeves are coupled or connected by a centraliser or further sleeve or screen, and/or optionally by or via first and second support ring.

Screens

A screen assembly, such as a downhole/sand screen assembly, comprising first and second screen portions or screens longitudinally coupled together, wherein there is provided a fluid flow path between the first and second screen portions or screen. Optionally, the first and second sleeves are coupled or connected by a centralizer or further sleeve or screen, and/or optionally by or via first and second support ring.

Downhole screen assembly

A downhole arrangement () comprises first () and second () members, a lock profile () fixed relative to one of the first and second members, and a lock member () for engaging the at least one lock profile. A release member () is provided which is moveable to selectively lock the lock member in engagement with the lock profile so as to selectively secure the second member relative to the first member. Such a downhole arrangement may permit a releasable connection between the first and second members.

Downhole arrangement

A downhole actuator () comprises a tubular housing () which includes an indexing profile () on an inner surface thereof, and an indexing sleeve () mounted within the housing (). The indexing sleeve () comprises an engaging arrangement including first and second axially spaced engagement members () which cooperate with the indexing profile () of the housing () to be sequentially engaged by an actuation object () passing through a central bore () of the indexing sleeve () to drive the indexing sleeve () one discrete step of movement through the housing () towards an actuation site.

Downhole apparatus and method

A downhole tool () comprises a tool housing () defining a central bore () and including a fluid port (), and a valve member () mounted within the housing () and being moveable from a closed position in which the fluid port () is blocked to an open position in which the fluid port () is opened. The tool () further comprises a catching arrangement () mounted within the housing () and comprising one or more radially moveable seat members (), and being configurable from a free configuration in which the seat members () permit an object () to pass through the tool (), to a catching configuration in which the seat members () catch an object () passing through the tool ().

A gravel pack assembly for a borehole has first and second joints and a foil. The basepipes of the joints connect end-to-end, and both of the basepipes having filters for filtering fluid passage from a borehole into bores of the basepipes. Transport tubes are disposed along the first and second joint, and a jumper tube expands across the connected ends of the basepipes and connects the transport tubes together. The foil encloses an area across the connected ends. The foil has an external surface defining an annulus thereabout with the borehole. The foil has end rings abutting the filters of the joints. At least a section of the foil leaks fluid from the borehole to the area enclosed by the foil, and at least a filter portion of the assembly filters the leaked fluid from the area to at least one of the first and second bores.

Leak-off assembly for gravel pack system

A downhole shifting tool () for shifting a downhole component () comprises a body with a positioning arrangement () provided on the body for engaging or interacting with a downhole component to provide alignment of the shifting tool with said component. The tool further includes a connecting member () provided on the body and being moveable to selectively engage a connection profile of the downhole component.
