The patented Anti Stick-Slip Tool (AST) from Tomax
counteracts excessive torsional peaks from the bit by
continuously regulating the depth of cut based on the
reactive torque. This allows a much more aggressive
choice of bits to maximise ROP without increasing
stick-slip. Using sharper bits requires less weight to
maximise ROP and the reduced compressional load
reduces friction, heat and wear.
The combination of the AST and aggressive bits is field
proven and has delivered substantial cost savings for
operators globally.
