NEXA-2 Non Elastomeric Sliding Sleeve
The NEXA-2 Non-Elastomeric Sliding Sleeve is a communication device with a ported inner sleeve that can be opened or
closed using a shifting tool by standard slickline or coiled tubing methods. Equalizing holes in the inner sleeve provide
pressure equalization between the tubing and casing annulus as the sleeve is opened. The Sliding Sleeve is made up to
and forms part of the tubing string. The NEXA-2 Sliding Sleeve is a shift-up-to-open tool.
The NEXA-2 Non-Elastomeric Sliding Sleeve uses common machined parts that allow the shift-open direction to be
changed from up-to-open to down-to-open by simply substituting different sub ends
The NEXA-2 Non-Elastomeric Sliding Sleeve is designed for use in high temperature wells to establish a means of
communication between the tubing string and the casing annulus for single-tubing or multiple-tubing string
completions. The NEXA-2 Sliding Sleeve may be used for directing flow from the casing to the tubing in alternate or
selective completions. Other applications include killing a well, spot acidizing and fracturing, or equalizing pressure
between an isolated formation and the tubing string.
