Drilling On-Gauge

The upset diameter of the screw on stabilizers increases the pressure differential at the bottom of the hole, which enhances the cleaning acion around the bottom hole assembly. The multi-point drilling on gauge stabilized motor consists of a set of reamer cutters incorporated in the bit box, that act as roller bearings, guiding the drill bit.
