Neyrfor
Turbodrilling systems
Overview
High-power turbodriling efficiency in harsh environments
Neyrfor™ turbodrilling systems outperform other drive systems by delivering significantly greater mechanical drilling power downhole. Specifically engineered to excel in high-temperature geothermal wells and the toughest, most abrasive formations, they provide premium borehole quality. Their design incorporates a fully concentric drive-train rotation, ensuring sustained optimal power during drilling and the capability to handle excessive loads over extended periods.
Increased ROP, reducing rig time
Toolface control and steerability in geothermal, abrasive, and hard rock formations
Extended drive train life, resulting in fewer trips
Configurable fit-for-purpose tool design reduces BHA failures and bit wear
Maximizing wellbore value
Neyrfor systems deliver consistent predictable toolface control and stabilization, ensuring that hole spiraling and microdoglegs are minimized. This enables customers to steer into fracture zones in geothermal wells with greater accuracy. By rotating the drive shaft at a higher speed while remaining dynamically stable, Neyrfor turbodrilling systems produce unsurpassed ROP without the negative effects of excess torque. The internal cavity of Neyrfor turbine systems have been optimized to enable additional stages for increased power output in hard rock drilling applications. Neyrfor systems also offer several blade designs that are customizable for specific environments.

For straight-hole applications, these turbodrilling systems act as natural dropping pendulum assemblies in rotary mode, which produces higher quality wellbores in less time than conventional BHAs. In directional drilling applications, the systems provide consistent predictable tool face control and stabilization to ensure that hole spiraling and microdoglegs are minimized.
