Sliding Sleeve

The Side Door Sleeve (SDS) is used together with tubing which, when open, allows flow between the well tubing and the annular area, opened or closed by standard slickline methods. It is designed with a landing nipple profile in the top sub, packing bores in both top and bottom sub, a non-elastomer seal package, and full tubing flow through the nipple and sleeve.

This circulation & production sleeve is installed as an integral part of the main tubing string, and any number can be run in a single string; the closing sleeve may be placed in three positions — open, equalising or closed. Available in mechanical and hydraulic configurations, sliding sleeves adapt to conventional completions through advanced multi-stage fracturing and intelligent wells.
