GFD Sliding Sleeve
The GFD 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. Equalising holes in the inner sleeve provide pressure equalisation between the tubing and casing annulus as the sleeve is opened. The Sliding Sleeve is made up and forms part of the tubing string. The GFD Sliding Sleeve is a shift-down-to-open tool.
The GFD 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 end subs.
The GFD 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 GFD 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 equalising pressure between an isolated formation and the tubing string.
