what is the difference between EUE tubing pup joint and NUE tubing pup joint?

The main difference between EUE (External Upset End) and NUE (Non-Upset End) tubing pup joints is in the way their connections are designed.

EUE connections have a larger diameter than the rest of the tubing, which helps to prevent the tubing from being pulled out of the wellbore under heavy loads. The EUE connection is also threaded, which allows for easier makeup and breakout of the connection. EUE connections are commonly used in high-stress applications, such as deep wells and deviated wells.

NUE connections, on the other hand, do not have the larger diameter or upset section. Instead, the end of the tubing is simply threaded with a smaller diameter. NUE connections are generally used in low-stress applications, such as shallow wells or where the tubing is not subjected to heavy loads.

Both EUE (External Upset End) and NUE (Non-Upset End) tubing pup joints are designed to withstand harsh production environments. However, EUE tubing pup joints are generally considered to be more suitable for harsh environments due to their thicker walls and deeper threads, which provide greater resistance to wear and tear. Additionally, EUE connections are typically stronger and more durable than NUE connections, making them better suited for high-pressure applications.

What is the application of tubing pup joint?

A tubing pup joint is a short length of tubing that is threaded on both ends and used to adjust the length of the tubing string in a wellbore. The purpose of a tubing pup joint is to make up for any length discrepancies between the tubing and the wellhead or other downhole equipment.

In oil and gas operations, tubing pup joints are often used when a tubing string is being run into the wellbore or when a tubing string needs to be pulled out of the wellbore. They are also used when making connections between different types of tubing, such as between a larger diameter tubing string and a smaller diameter one.

By using tubing pup joints, operators can ensure that the tubing string is properly positioned and connected to downhole equipment, which helps prevent leaks and other issues that can occur when the tubing string is not properly installed. Additionally, tubing pup joints can be used to replace damaged or corroded sections of tubing without having to remove the entire string, which can save time and money.
