Vacuum Insulated Tubing

Vacuum Insulated Tubing (VIT) and Insulated Tubing replaces oil tubing for heavy oil recovery by steam injection improves project economics. With the following advantages: 

• Reduces heat loss ensuring optimal steam quality being injected into the oil formation.

• Minimizes heat stress on well casing and cement mantle, decreases unwanted annulus pressure.

• Improves well life cycle cost and avoids failure due to well integrity issues.

• Optimized cyclic steam stimulation cycles for better overall project economics.

• Important technology for the economic production of deeper heavy oil formations.
