The GL 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. The Sliding Sleeve is made up to and forms part of the tubing string. The GL Sliding Sleeve is a shift-up-to-open tool.
The GL Sliding Sleeve is used to establish a means of communication between the tubing string and the casing annulus
for single-tubing or multiple-tubing string completions. The GL 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.
