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.
