In the demanding world of oil and gas exploration and production, efficiency and reliability are paramount. Coiled tubing, a flexible steel tubing wound on a reel, offers a versatile solution for various downhole operations. However, securely connecting the Bottom Hole Assembly (BHA) to the coiled tubing is crucial for successful deployment. This is where the Roll-On Connector comes into play.
Understanding the Roll-On Connector
The Roll-On Connector is a specialized type of connector designed specifically for coiled tubing applications. It features a unique design that combines a grooved end with threads on the opposite end. This configuration enables a secure and reliable connection between the BHA and the coiled tubing.
The Connection Process
The process of connecting the BHA to the coiled tubing using a Roll-On Connector involves these steps:
