The proprietary Neyrfor Turbodrill is designed to provide faster rates of penetration, operate in higher temperature applications, deliver longer downhole life, and produce better wellbore quality than conventional positive displacement drilling motors. Neyrfor Turbodrills offer the customer significant cost savings over conventional drilling systems in most applications.
Energy Efficiency
As an energy conversion device, turbodrills and PDMs provide more power to the bit when they are more efficient. Because of the nature of the free-running, balanced design os a turbodrill, it is far more efficient than a PDM, which creates more internal friction and wastes energy due to unbalanced and eccentric design.
Power Output
The superior energy efficiency of the turbodrill translates directly into more power available at the bit to destroy the rock faster for high rates of penetration. The power output of the turbodrill experiences only negligible decreases over time, the turbodrill maintains its high power output throughout the run.
Reliability/Operating Life
Turbodrills, designed as precision high-performance downhole tools, achieve downhole runs of of over 400 hours to 600 hours.
HPHT Capability
Because a turbodrill has no elastomeric material in the powersection, too performance is exceptional even when run in high temperatures and pressures.
Underbalanced Drilling
Turbodrills can operate effectively in applications where two-phase drilling fluid is used. In critical applications where there are concerns about fluid contamination of the reservoir, turbodrilling with highly gas-cut mud systems can help ensure that both drilling and production objectives are met.
Borehole Quality
Turbodrills consistently deliver a smooth and concentric wellbore. With superior toolface control and high degree of stabilization on the turbodrill, hole spiraling and severe localized doglegs are minimized. The result is trouble-free running of casing and reduced cementing costs.
Operating Costs
The ultimate advantage of a turbodrill is the tool’s ability to consistently deliver lower operating costs by reducing srilling time. The value of the more robust high performance turbodrill is realized by increased ROP, the substantial reduction in tripping time due to non-planned events and the increase in operational efficiency derived from more time on-bottom due to high tool reliability and extended drive train life.
