Milling Before Running Casing Surface testing a Section Mill before RIH to create a window inside a 9 5/8" #casing, during a P&A program that has a micro annulus in the B-annulus. Mill is designed for milling tubular fish, cleaning a casing internal diameter before running a casing patch and suppressing the damaged parts of a casing. Mill can be perfectly directed into the fish head, avoiding side tracking. The pilot is hardfaced for optimum resistance to wear and enables perfect, smooth guiding

The HEAVY METAL™ swarf-free section milling service, by Baker Hughes, a GE Company (BHGE), eliminates swarf-to-surface through a unique upward milling process, depositing swarf deep in the rathole, allowing a robust rock-to-rock barrier. | Drilling Foreman
