Sliding Sleeves

Shift with wireline, coiled tubing (CT), or interventionless operations

A shifting tool and wireline or CT are used to shift the sleeve open or closed. Alternatively, an external shroud can be run in the closed position while the inner sleeve is open. The shroud is sheared hydraulically with annular pressure to establish communication. Heavyweight mud can be displaced from the annulus to the tubing without a slickline or CT trip to open the sleeve. Standard slickline or CT methods are used to close the sleeve.

Selectively produce multizone wells

The sliding sleeve separation tool enables flow from the casing and tubing annulus through an open sliding sleeve and up the production tubing while blanking off the tubing just below the sliding sleeve. This allows alternating production of two zones (isolated from each other by packers) without commingling.

When production from an upper zone is not wanted and the sliding sleeve leaks fluid between the tubing and casing annulus when closed, a packoff can be used to isolate the zone. The sliding sleeve packoff is attached to a lock, which anchors and seals in the sliding sleeve. The packoff assembly isolates the sliding sleeve ports and prevents fluid migration between the tubing and casing annulus while allowing restricted flow up the production tubing from below.
