SteeringWheel Gauge
The SteeringWheel gauge provides lateral stability without loss of steerability and is considered suitable
for applications that encounter formations which are particularly susceptible to inducing lateral vibrations,
or where borehole quality is of paramount importance or where the hole angle is very high and gravitational
forces are at their highest.
Active Gauge and DAG Cutters Design Solution
In order to maintain sufficient steerability a partial SteeringWheel™ geometry is used. This provides a
break in the ring continuity so that Active
Gauge (AG) cutting elements can be placed along the edge of the
open ring section. In addition, Dual
Action Gauge (DAG) cutters
are positioned on the back angle of the ring to improve sidecutting when the bit is tilted by the bias unit.
