An actuation member for use in fracking operations, which immediately prior to fracking locates a sand screen at a desired location along a tubing liner and eliminates having to trip out the frac string prior to commencing production. The actuation member comprises a cylindrical hollow collet sleeve, with one or more radially-outwardly biased protuberances forming a unique profile which further matingly engages a corresponding mating profile on one of a plurality of sliding sleeve members in the tubular liner. A longitudinally-extending sand screen is provided, longitudinally slidable on the actuation member. A spring member, adapted to be forcibly compressed by the sand screen member when pressurized fluid is applied, and decompressed upon removal of pressurized fluid, is further provided on the actuation member.

An apparatus has been described, including a tubular housing including opposing first and second end portions and defining an interior surface, an exterior surface, and an internal flow passage; an open inflow area extending radially through the tobular housing and adapted to distribute the radial flow of a fluid from the internal flow passage to the wellbore; a closure member extending within the tubular housing and adapted to cover the open inflow area; and a filter defining a plurality of gaps, the filter concentrically disposed about the exterior surface of the tubular housing and extending axially along at least the open inflow area. In an exemplary embodiment, the open inflow area includes a plurality of openings formed radially through the tubular housing and defining a tubular injection interval extending axially along the tubular housing. A system and assembly have also been described, each incorporating elements of the above described apparatus.

Downhole pumps may include, at the inlet, a component that reduces the amount of water taken up by the pump. For example, a downhole assembly may include a tool string that includes a fluid pump, a fluid intake subassembly, a motor, and a downhole control system each coupled such that a fluid flowing into the fluid intake assembly is conveyed to the fluid pump; one or more inlets defined in the fluid intake subassembly; a flow line fluidly coupled to at least one of the one or more inlets and containing a filter component that contains a filter media at least partially coated with a relative permeability modifier (RPM), wherein the fluid flowing through the flow line contacts the RPM.
