Vacuum insulated tubing (VIT) has been used successfully to mitigate the potentially harmful effects of annular pressure buildup (APB). In a recent deepwater installation, the subject well had lost alternate APB mitigation capability through a series of events. VIT was then chosen as the only viable technology.

A common design companion of VIT is gelled brine, chosen to decrease annular natural convection driven by heat loss around the VIT connections.
