A string mill is a robust milling tool used in drilling and sidetracking operations, specifically designed for milling over existing casing, liners, or tubular strings. These tools are vital in operations where precise cutting or removal of metal or composite downhole structures is required, particularly in openhole whipstock sidetracking scenarios.
At Progrynd, our string mills are engineered for durability and efficiency, ensuring clean, controlled milling operations with minimal damage to surrounding structures.
🛢️ String Mill Applications in Oil & Gas Drilling
String mills are primarily deployed in the following scenarios:
- Casing Milling: When older casing must be milled out for access or redirection.
- Window Milling: To assist in whipstock operations by enlarging the casing window.
- Clean-Out Operations: Removing scale, hard debris, or downhole obstructions.
- Sidetracking Operations: Providing smooth sidetrack paths by conditioning the borehole.
Their versatility makes string mills an essential tool in the toolbox for engineers performing complex whipstock jobs or sidetracking operations.
