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

The device has replaceable upper and lower seals which are easy and inexpensive to replace. They can be of various elastomer types.

The SLA Sliding Sleeve has no profile in the upper sub nor seal bores in either the upper sub or lower sub. This allows greater ID clearance. However, it restricts the installation of various flow control devices, and should be used with careful consideration.

The SLA 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 SLA Sliding Sleeve open and closed.  The tool is designed to that normal wireline activities will not open or close the sleeve inadvertently. Upward jarring opens the Inner Sleeve and downward 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.
