Why Mandrel Type Casing Hangers Are Revolutionizing Drilling.

The oil and gas industry is always evolving, and drilling engineers, operators, and service companies are always looking for innovative ways to improve drilling performance, increase efficiency, reduce costs, and enhance safety. One of the recent developments that have attracted attention and gained popularity is the mandrel type casing hangermandrel type casing hanger.

What is a Mandrel Type Casing Hanger?

A casing hanger is a vital component of a wellhead assembly that supports the weight of the casing strings and creates a seal between the casing and the wellhead. Traditionally, casing hangers were installed through the use of slip-type or threaded-type hangers, which required threading or clamping the casing hanger onto the casing to be supported.

A mandrel type casing hanger, on the other hand, works differently. It does not require threading or clamping, but instead, it is installed by pushing the casing hanger into the wellhead bore. Once in position, the mandrel casing hanger exerts radial expansion forces on the casing and locks it securely in place. By eliminating the need for threading or clamping, mandrel type casing hangers offer faster, safer, and more efficient casing hanger installation.

Advantages of Mandrel Type Casing Hangers.

1. Enhanced Safety.

Mandrel type casing hangers offer enhanced safety benefits compared to traditional slip or threaded hangers. Because mandrel casing hangers are pushed into position, there is less risk of dropped objects, which can cause injuries or damage equipment. Moreover, mandrel casing hangers can be locked in place quickly and easily, reducing the time workers spend near the wellhead.

2. Reduced Installation Time.

Mandrel type casing hanger installation is faster than traditional methods because the mandrel hanger is simply pushed into place. This reduces installation time by up to 50%, which can translate into significant cost savings for drilling operations.

3. Improved Well Integrity.

Mandrel type casing hangers create a better seal between the casing and the wellhead than traditional hangers. The radial expansion forces applied by the mandrel hanger create a more even, consistent contact between the casing and the wellhead. This helps maintain well integrity, reduce the risk of leaks, and increase the lifespan of the well.

Conclusion.

Mandrel type casing hangers offer significant benefits to drilling engineers, operators, and service companies. They are safer, faster, and more efficient than traditional hangers, and they improve well integrity, reducing the risk of leaks and increasing the lifespan of the well. With such benefits, it is no wonder that mandrel type casing hangers are becoming increasingly popular in the industry.
