摘要: A tool for wellbore sidetracking operations has been invented, the tool, in one aspect, having a body, a milling section on the body for milling an opening in a tubular in a first wellbore in a formation, the milling section having milling material thereon, and a drilling section on the body for drilling a second wellbore beyond the window into the formation. A method has been invented for forming an opening in a tubular in a first wellbore in a formation and for drilling a second wellbore from the opening in a single trip procedure, the method positioning a mill drill tool in the tubular at a location at which an opening is desired in the tubular and from which a second wellbore is desired to be drilled, the mill drill tool having drilling apparatus for drilling the second wellbore and milling apparatus for milling an opening through the tubular, milling the opening in the tubular with the milling apparatus thereby exposing the formation for drilling, and drilling with the drilling apparatus a second wellbore beyond the opening in the tubular into the formation.
