Turbodrills use the mechanical energy of the rotary table, and the hydraulic energy provided by the rig’s drilling fluid pumps to deliver power to the drill bit. These proprietary tools are designed to provide faster rates of penetration, operate in much higher temperature applications, deliver longer downhole life, and produce better wellbore quality than conventional positive displacement drilling motors. In many applications Neyrfor Turbodrills offer the customer significant cost savings over conventional drilling systems.
