Sliding Sleeves

HMS manufactures high-performance Sliding Sleeves, designed as essential downhole tools for selective zone control and wellbore communication. Installed in the production tubing, sliding sleeves provide flexibility and reliability in multi-zone completions and intervention operations.

Key Features

• Versatile Functionality – enables communication between tubing and casing for:
  • Selective production from multiple zones
  • Stimulation and testing of individual zones
  • Displacement of tubing or casing after wellhead installation
  • Well killing by circulation
  • Circulation of treatment chemicals or agents
• Sealing Integrity – equipped with replaceable V-type upper and lower seals to ensure maximum sealing performance for extended downhole service.

• Material Compliance – available in metallurgical grades conforming to NACE MR 0175, suitable for H₂S and CO₂

• Precision Engineering – Top and Bottom Subs feature high-finish seal bore IDs to accommodate isolation sleeves and other sealing devices.

Applications

• Multi-zone completions requiring selective production
• Well stimulation and testing operations

• Chemical treatment and circulation processes

• High-pressure, corrosive environments demanding long-term reliability
