Research and Development of High-Performance Section Milling …

Casing section milling technology is widely used for sidetracking old wells or well abandonment operations. Conventional section milling tools for small- and high-steel-grade casings in deep wells pose problems, such as long cutting time, and slow section milling speed leads to a short section milling footage. This study concerns the design of …Web
