Sliding Sleeve (SSD)
The device is designed to connect the pipe space with the casing space by moving the inner sleeve, which can be opened or closed using standard tools on cable equipment or coiled tubing. Holes in the inner sleeve provide pressure equalization between the tubing and casing space when the valve is opened. The PXA circulation valve is opened upwards using a tool to move the sleeve. The PXA circulation valve can be used to direct flow from tubing space to tubular space in selective layout. Other applications include killing wells, performing acid treatments and hydraulic fracturing, or equalizing pressure between isolated formations and a tubing string.
