This paper introduces the novel concept of a {open_quotes}flexible{close_quotes} polycrystalline diamond compact (PDC) bit, and its capability to reduce detrimental vibration associated with drag bits. The tilt flexibility, introduced at the bit, decouples the dynamic motion of the bottom hole assembly (BHA) from that of the bit, thus providing a dynamically more stable bit. The paper describes the details of a prototype 8-1/2 inch flexible bit design together with laboratory experiments and field tests which verify the concept.
