MUDHAMMER

The Drillstar MUDHammer is the first hammer drilling solution capable of using most standard, weighted drilling fluids.

The fruit of 20 years of research and development, it brings percussion drilling performances all the way down to deeply buried formations. As a purely percussive technology, it relies on 2 main components:

• A high-power, fluid-driven downhole hammer, delivering high-energy impacts dozens of times per second.
• A range of specific hammer bits, designed to deliver the best ROP based on the formation and depth drilled.

Unlike PDC and Roller cone bits, hammer bits rely primarily on impact energy to drill rather than weight & rotation. This means high energy levels can be transmitted to the rock while maintaining low WOB, low RPM and low torque levels.

Unlike existing downhole fluid hammers, the Drillstar MUDHammer is not designed to be used with conventional PDC or Roller cone bits, due to the much higher power transmitted to the bit.

This higher drilling power translates directly into higher ROP, especially in hard or very hard formations. ROP gains of 200% and more over rotary drilling have been observed in hard lithologies.
