Vacuum Insulation Tubing and Casing
Secondary and tertiary oil recovery processes can involve the use of heat. Oil deposits in such oilfields are heavy and need to be melted before they are pumped to the surface.
The high-temperature conditions for such oil wells can pose a serious challenge to the ordinary oil recovery equipment. The normal tubing and casing will conduct the heat and get damaged. The activity of oil recovery process will be negatively impacted.
Vacuum insulation tubing (VIT) and Vacuum insulation casing (VIC) are manufactured to deal with such conditions. They mitigate the impact of temperature on the overall oil recovery process.

How Vacuum insulation Tubing and Casing Works
The working mechanism of a vacuum insulation tubing and casing depends on the presence of vacuum which provides a form of insulation. The vacuum separated the casing and the tubing pipes. This is unlike in most equipment where the casing and tubing are connected to each other directly.
The vacuum minimizes heat loss from the tubing and the casing, either by conduction or convection. The extra insulation minimizes heat transfer through radiation. Here an insulation blanket is used for covering the outside diameter and the inner tube.
The outer and inner diameter is welded creating a vacuum between the casing and the tubing. After that, the tubing is sealed completely so that the quality of the infrastructure is not compromised.
The materials that are used for the vacuum insulation tubing and casing have a very low thermal conductivity. This is done to further minimize the loss and transfer of heat during the oil extraction process.
Once a vacuum has been established between the casing and tubing, efforts are upped to ensure that it remains in the same state. This is because the oil production process can impact the effectiveness of the vacuum layer.
For instance, the presence of hydrogen in the vacuum can diminish its power and effectiveness.
Reliable vacuum insulation tubing and casing manufacturers build VIT and VIC that minimize the penetration of hydrogen into their systems. Some chemical compounds such as Getter are added to trap and eliminate hydrogen from the vacuum layer.
Timely servicing of the vacuum insulation tubing and casing will also play a big role in ensuring that your equipment is always in perfect condition.
Application of Vacuum insulation Tubing and Casing
Vacuum insulation tubing and casing have proven its effectiveness in various oilfields across the globe. Here are some of these areas:
-Shell Tahoe: Shell Tahoe oil field which is located in the Gulf of Mexico was the first place where vacuum insulation tubing and casing was installed. This oilfield occupies a 1400 ft water depth and was completed in 1996.
Approximately 7200ft of vacuum insulation tubing and casing was installed here.
-BP’s Troika: BP Exploration oilfield that is located in Houston Texas is was also among the first oil fields to experience the benefits of vacuum insulation tubing and casing. With a water depth of 2060 ft, VIT and VIC were ideal since most oil wells had attained the end-of-life conditions.
Subsea Application
It is imperative to note that vacuum insulation tubing and casing can also be used on the subsea applications. For example, the Troika oil wells embraced the equipment as they were ideal for the temperature of the wells.
Another perfect example of the subsea application is the Amerada Hess’ Penn oilfield which is Garden Banks. The field has a water depth of 1456 ft and features a high reservoir temperature.
Since then, vacuum insulation tubing and casing, it has found its way in many different oilfields.
What are the Benefits of vacuum insulation tubing and casing?
There is no doubt that vacuum insulation tubing and casing has an important role to play in the official recovery. It is more vital in the tertiary stage of oil extraction where you have to deploy some external aid.
So, what are some of the benefits of using this insulation vacuum and not just the ordinary tubing and casing equipment?
-Minimize heat loss from steam: Are you using steam injection as a method of oil extraction? You would what the steam to reach the oil deposit when it is still hot.
Vacuum insulation tubing and casing will help you achieve this goal. It will preserve maximum heat which will eventually guarantee the effectiveness of the oil extraction process.
-Protects the well from the effects of heat: The insulation that is provided by the casing and the tubing ensures that heat is concentrated in the desired areas. The remaining sections of the oil well will remain at their usual standard temperatures. The cement mantle which is just next to the casing won’t be affected by the high temperatures emanating from the insulation casing and tubing.
-Optimizes the effectiveness of the steam: Since the steam will reach the oil deposits while still hot, you will be able to extract most of the oil from the oil well. This will improve the economic value of the wellbore.
-Improves the oil well lifecycle of the well: As we have seen, this agile method of casing and tubing protects the well from structural degradation. This helps to increase the productivity of the oil well hence longer lifecycle.
