This paper presents the results of developmental work applied to modify off-the-shelf polycrystalline-diamond-compact (PDC) bit designs to incorporate low-friction-gauge technology. The low-friction gauge limits harmful bit-whirl tendencies by directing the radial bit imbalance to a gauge pad that makes smooth sliding contact with the wellbore wall. Field testing indicates that use of a low-friction gauge improves bit life and rate of penetration (ROP).
