Collection: Vacuum Insulated Tubing – VIT
At Novarix, we supply advanced Vacuum Insulated Tubing (VIT) designed to dramatically reduce heat loss in Steam Assisted Gravity Drainage (SAGD) operations. By minimizing steam consumption, VIT improves well efficiency, reduces operational costs, and lowers environmental impact.
How VIT Works
VIT consists of two concentric tubing strings with the thin layer of air between them removed, creating a vacuum barrier. Since heat transfer through a vacuum is extremely limited, this design keeps steam hotter for longer as it travels downhole. The result: significantly less heat loss to surrounding formations.
Key Benefits in SAGD Applications
- Reduced Steam Consumption – Lower fuel and water usage by minimizing the need for additional steam injection.
- Faster Pre-Heat Times – Research shows VIT-equipped wells can require as little as 75 days of pre-heating, compared to up to five months with conventional tubing.
- Lower Operating Costs – Decrease natural gas usage and water consumption.
- Environmental Impact Reduction – Reduced greenhouse gas emissions through more efficient steam utilization.
