The Evolution Model NEXO Sliding Sleeve is a down hole device, normally screwed into the production tubing, that allows communication between the tubing and the casing.

The device contains non-elastomeric (Teflon® encapsulated Viton) O-rings as well as replaceable upper and lower easy-to-replace Vee seals.  The Vee seals can be of various elastomer types.  The standard seal material is a carbon graphite/Teflon® composition.

The NEXO Sliding Sleeve has an Otis® X-style Selective Nipple profile and a sealing bore in the upper sub which serves as a receptacle for other Flow Control devices such as blanking plugs and separation tools.  The lower sub also contains a seal bore.

The NEXO Sliding Sleeve can be installed at any point in the tubing string.  More than one can be installed without any loss of function. When multiple sliding sleeves are in place, they can be selectively opened and closed in the tubing string.

The EB Shifting Tool is used to shift the NEXO Sliding Sleeve open and closed.  The tool is designed to that normal wireline activities will not open or close the sleeve inadvertently. Downward jarring opens the Inner Sleeve and upward jarring closes the Inner Sleeve.  It is available in tubing sizes from 1.900” up to 5 ½”, in 4140 L-80 material, as well as premium steels such as 9 Cr, 13 Cr and Incoloy 925. The standard thread is EUE, but various premium threads may be machined into this tool as required.
