There are cost advantages to reaming while drilling. The pilot hole offers good directional control while the enlarged hole from reaming creates the right conditions for running casing or completion equipment which relates to savings in time and cost. An underreamer is device designed to run in conjunction with a drill bit. It has cutters that can be expanded or contracted by mechanical or hydraulic means and used to enlarge or ream a borehole below the casing. Baker Hughes and Statoil jointly developed the industry's first on-command digital reamer as a single size prototype in 2007.
