Abstract

See full text

A fixed cutter drill bit includes sets of cutter elements mounted on the bit face, each set including at least two cutters that are mounted at generally the same radial position with respect to the bit axis. The cutter elements of a set are positioned on different blades of the bit and are mounted having their cutting faces are out-of-profile, such that certain elements in the set are exposed to the formation material to a greater extent than other cutter elements in the same set. The cutter elements in a set may have equal diameters or may vary in size. The bit exhibits increased stability or vibration resistance, and drills initially as a 'light-set' bit and later as a 'heavy-set' bit.
