Sliding Sleeve Door

Tendeka s ssd enables selective flow in production and injection directions.

Sliding sleeve door.

Sliding side door ssd open close sliding sleeve ssd enabling selective flow for production and injection applications. The tool has one connection which minimizes potential leak paths the non elastomeric seal. The sliding sleeve packoff is attached to a lock which anchors and seals in the sliding sleeve. Open close sleeves are shifted between a full open position and a closed position.

There are two main categories of sliding sleeves. Control tubular annular communication in challenging environments. Their main uses are to shut off flow from one or more reservoir zones or to regulate pressure between zones. 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.

The act model l sliding sleeve is a downhole tool used to establish communication when desired between the tubing and annulus. Once the first sleeve was opened the well was unloaded and the second sleeve opened a few days later. The ssd can be combined with tendeka s inflow technologies to provide inflow control when in the open position. The durasleeve sliding side door circulating and production sleeve is a full opening device that can be operated using standard slickline methods.

Selective and or top no go locking devices are available for use with the sleeve. It required two strokes to fully open the sliding sleeve door. Acting as downhole control valves sliding sleeves can also be used to circulate fluids from the annulus to the tubing above the production packer or to inject water into individual zones during waterflood operations. A sliding sleeve is a standard component for the completion of an oil or gas well.

It incorporates an internal sleeve that when open enables communication between the tubing and tubing casing annulus.
