ABSTRACT:
A wellbore mill has been invented which has milling apparatus with a starting mill and a finishing mill, the starting mill having a central channel extending longitudinally therethrough, the central channel having an interior surface with carbide cutters thereon. A milling method has been invented for finishing a window in a casing in a wellbore, the window having been begun with a first mill, the method including inserting a second mill apparatus into the wellbore adjacent the window, the second mill apparatus having a milling system with a starting mill and a finishing mill, the starting mill having a central channel extending longitudinally therethrough, the central channel having an interior surface with carbide cutters thereon, rotating the second mill apparatus to finish the window. A two-trip milling operation has also been invented for milling a finished window in a casing in a cased wellbore, the wellbore having installed therein an anchoring-orientation device, the operation using the wellbore mill described above. In one aspect the mill(s) mill off high center producing a piece of casing which enters into the hollow portion of the mill(s).
