Neyrfor Turbodrills

When running a turbodrilling operation, efficiency and power are critical because the drill bit is isolated from the drillstring. To maintain optimal power while remaining on bottom for extended periods of time in turbodrilling applications, Neyrfor high-performance turbodrills are designed with a fully concentric drive-train rotation.

Neyrfor turbodrills have a proven track record for high-temperature operations around the world. Our suite of best-in-class HT technology and high-temperature-certified engineers includes products and services for directional drilling, MWD, and LWD. See the HT suite

The Neyrfor drive system is extremely efficient at converting hydraulic energy from the mud column to mechanical energy at the bit, meaning Neyrfor turbodrills deliver more downhole mechanical drilling power than any other drive system under equal hydraulic conditions. The tool rotates the drive shaft at a higher rpm while remaining dynamically stable, so you experience unsurpassed ROP without the negative effects of excess torque.

When compared with positive displacement motors (PDMs), Neyrfor turbodrills offer superior

• energy efficiency
• power output
• reliability and operating life
• vibration mitigation
• high-pressure, high-temperature (HPHT) capabilities
• directional and underbalanced drilling capabilities
• improved borehole quality.

Straight-hole turbodrilling

For straight-hole applications, Neyrfor turbodrills act as a natural dropping pendulum assembly in rotary mode. This action consistently maintains verticality and provides higher ROPs and higher-quality wellbores versus conventional BHAs.

Directional and horizontal turbodrilling

Neyrfor turbodrills provide consistent, predictable drilling rates for directional and horizontal turbodrilling applications. Neyrfor turbodrills have exceptional toolface control, ensuring that directional objectives can be achieved in even the most demanding environments.

Thru-tubing turbodrilling

With the most power of any slimhole drive system, Neyrfor thru-tubing turbodrills give operators maximum performance. Their concentric design makes them the superior service for low-bottomhole-pressure environments, two-phase fluid gas systems, acidizations, and hot-hole productions.
