VACUUM INSULATED TUBING

Vallourec Tube-Alloy’s Vacuum Insulated Tubing (VIT^TM) is a high-performance, double-walled tubular product that provides temperature isolation in response to various production challenges such as permafrost issues and high-viscosity oil. VIT is the highest level of thermal insulation available in a tubular. It is ideal for deepwater projects and other specialized applications including:

Reduction of Annular Pressure Buildup (APB)
High production volumes leading to high temperatures can cause dangerously high pressures to develop if the casing annuli are sealed. VIT keeps heat inside the production tubing, thereby reducing APB to an acceptable level and often preventing the collapse of deepwater casing strings.

Cold Startups
VIT maintains wellbore temperatures to prevent hydrate formation near the mudline which can impede a cold startup.

Reduction of Paraffin Deposits
VIT helps to maintain flowing product temperature above the paraffin deposition temperature.

Well Testing
Some well test operations involve alternate periods of production and shut-in. When deepwater operations are involved, VIT helps prevent paraffin and hydrating problems.

Heavy Oil Production
VIT helps maintain lower viscosity levels, reducing the need for artificial lift and increasing total ultimate recovery.

Steam Flooding
VIT provides excellent steam quality downhole, playing an integral role as the injection string in constant injection, “huff and puff” and Steam-Assisted Gravity Drainage (SAGD).
