GL Sliding Sleeve
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 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 acidising and fracturing or equalising pressure between an isolated formation and the tubing string.
Features & Benefits
- Closing Sleeve Upper seals are designed to accommodate elastomer swell, to prevent pressure trapping and to require only a moderate and consistent shifting force.
- Lower seals have all of the above features and in addition are integrally mold-bonded to the Closing Sleeve, allowing the "GL" Sliding Sleeve to be opened against severe differential without seal damage
- Collet Lock on Closing Sleeve provides a uniform shifting force requirement. Immune to solids.
- GF Top No-Go Nipple Profile
- Closing Sleeve Skirt provides insurance against being blown up the hole during an opening operation. This is accomplished by placing the flow path above the engaging members of any shifting tool.
- Seal bores are contoured and polished to pass chevron packing without damage
- Manufactured standard in 4140 18-22 Rc Alloy Steel with Viton elastomers for Standard and H2S Service
