Turbodrill Handbook
Innovative Leaders in Superior Performance TurbodrillingNeyrfor* turbodrilling technology has led the industry for over half a century. With a history of unmatched drilling performance and reliability in the industry, our tools, technology and operational expertise provide customers with superior drilling efficiency in a broad range of drilling applications.
While turbodrills are often associated with extreme applications such as HPHT or hard rock drilling, Neyrfor Turbodrills* consistently deliver enhanced performance in conventional drilling applications including:
■ vertical performance drilling ■ s-shape, tangent, and horizontal directional drilling ■ sidetracking ■ milling ■ re-entries ■ extended reach ■ medium- and long-radius drilling
Regardless of the application, Neyrfor Turbodrills provide high performance and precise directional control without sacrificing hole quality or ROP, even at extreme depths and downhole environments.
The Turbodrilling Advantage Energy EfficiencyBoth Neyrfor turbodrills and PDMs are in essence energy conversion devices, converting the hydraulic energy of the drilling fluid into mechanical energy to drive the drill bit. As such the actual power delivered is very dependent on the efficiency of the energy conversion. Because of the intrinsic nature of the free-running and concentric balanced design of a turbodrill, it is far more efficient than conventional drilling motors.
Power OutputThe superior energy efficiency of the turbodrill translates directly into more power available at the bit to sheer and grind the rock faster for higher rates of penetration. And, because the power output of the turbodrill does not deteriorate over time, the turbodrill maintains its uniformly high power output throughout every run.
Reliability and Operating LifeNeyrfor turbodrills, designed as precision high performance downhole tools, routinely achieve downhole run times of over 400 hours and, in some circumstances, even above 600 hours.
Vibration MitigationExcessive downhole vibrations have been shown to damage expensive downhole electronics, contribute to accelerated bit wear and adversely affect the efficiency of the total drilling operation. The concentric rotation of the turbodrill allows the passage of drilling fluid through the tool to rotate the drive shaft at a high RPM while remaining dynamically stable about the geometric axis. The absence of lateral vibration (off-center motion) means that a greater portion of the available energy generated by the turbodrill is applied directly to the formation.
HPHT CapabilityThe all metallic turbodrill configuration has no elastomer material in the power section to degrade in harsh drilling environments, therefore tool performance is exceptional even in high temperatures and pressures.
Turbodrill Handbook
Directional CapabilityFor any given bent housing angle, turbodrills have been shown to provide greater directional responsiveness and thus can deliver a higher DLS when it is necessary to achieve directional objectives or can achieve normal requirements with a lesser bend. Also, turbodrills operate with much less fluctuating and reactive torque than PDMs making it much easier to control and predict the tool face and resultant directional response.
Underbalanced Drilling CapabilityTurbodrills 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 QualityGoal: Maximize Wellbore Value. turbodrills consistently deliver a smooth and concentric wellbore. With the superior toolface control and use of stabilization on the turbodrill, hole spiraling and micro doglegs are minimized. The result is a hole with minimal rugosity, this enhances wellbore evaluation, casing running, cementing, and the minimization of problems drilling ahead
Cost-per-FootThe ultimate advantage of a turbodrill is the tool’s ability to consistently deliver lower operating cost by reducing drilling 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 than conventional drilling motors.
Custom Configurations for Every ApplicationStraight-Hole High-Performance TurbodrillingIn straight-hole vertical applications, the stabilizer configuration of the Neyrfor turbodrill combined with the much lighter weight on bit required compared to rotary or PDM assemblies, results in a natural dropping tendency. This tendency provides a high-performance drilling solution which maximizes ROP, produces a high-quality wellbore and very consistently maintains verticality. Coupled with unsurpassed downhole longevity and reliability, this makes the turbodrill the obvious choice for operators seeking to minimize drilling time and reduce operating costs.
Directional and Horizontal TurbodrillingNeyrfor turbodrills excel in the demanding world of directional and horizontal drilling.
With the ability to offer consistent, predictable build rates, combined with unmatched toolface control, the Neyrfor Delta* and Neyrfor Traditional* turbodrills ensure that directional objectives can be achieved in the most demanding applications. The directional turbodrill has an outstanding track record providing superior performance in extreme applications such as sidetracking operations below 22,000 ft TVD in HPHT environments. In its robust, all-metallic configuration, the exceptional durability of the turbodrill has allowed it to completely drill both legs of dual-lateral wells in a single run without tripping out of the hole.
Thru-Tubing TurbodrillingWith the most power of any slim-hole drive system, the Neyrfor TTT* thru-tubing turbodrill offers the operator the ability to achieve maximum performance in any thru-tubing operation. The design superiority of turbodrills makes them the preferred solution to provide a performance advantage in low bottom-hole pressure environments, in two-phase gasified fluid systems, in acidizations, and in hot-hole production environments. Notably, the Neyrfor TTT’s ability to run on large percentages of gas, rather than just fluid, allows continuous well production during remedial and underbalanced drilling operations.

Neyrfor LC3Turbodrill Locking Clutch
Drilling environments that induce bit sticking can certainly benefit from using the Neyrfor LC3* turbodrill locking clutch system. When added to a Neyrfor Traditional or Neyrfor Delta series configuration, it assists in freeing the bit if it becomes stuck during drilling or reaming. The clutch engages when the turbodrill drive shaft stops or the rpm is below that of the rotary string speed. Accordingly, the string along with the turbodrill housing and the resulting connected output drive shaft linked together by the locking clutch allows the operators to apply string torque directly to the bit by the LC3* clutch system from the top drive or rotary table. Once the bit has become free, the clutch disengages and normal drilling operations can be resumed.
Bit type and directional well applications are evaluated on a per well basis.
LC3 Performance Improvements ■ Material Changes—1,400% Improvement in Fracture Toughness ■ Design Modification—25% Improvement in Drilling Mode Wear ■ Optimized placement to be run with both Neyrfor Traditional and
Neyrfor Delta series turbodrills—100% Improvement in Reliability while Drilling Directional Wells.

■ †Nominal weights and lengths. Actual values may vary.
Mud Quality Guidelines ■ The turbodrill has tight running clearances that are susceptible to jamming
or plugging. As such, the mud must be free of coarse/fibrous material/plastic beads, or other foreign material.
– Particles or mud solids of 250 to 1,000 micron (0.010 to 0.394 in) can jam the turbodrill and should be removed from the system.
– Larger material may potentially plug the turbodrill.
■ Before turbodrilling, ensure the mud is clean. – All mud brought to location should be pumped across the shakers
before entering the system and then re-circulated over shakers, if possible.
– If the system is thought to be contaminated, it must be cleaned to ensure a successful turbodrill run.
– Circulate the mud across the shakers with a maximum screen size of 80 mesh (177 micron). Finer screens are preferred.
– Use mud cleaner or centrifuge to remove other unwanted solids. – Ensure that suction line screens are installed and clean. – Ensure the slugging pit does not contain incompatible LCM, foreign
material, or excessive solids. – Ensure that degasser and gas buster have been circulated through
with clean mud. – Ensure any other mud cleaning equipment has been circulated
through with clean mud.
■ Always run a drill pipe screen with a fine mesh and check it often, especially before turbodrilling to confirm the mud is free of foreign material.
■ When adding barite or chemicals to the mud, make sure they are thoroughly mixed and blended before adding to the active system. This will reduce the probability of undispersed Barite or other chemicals going straight into the pump suction lines, as this may result in plugging the turbodrill.
■ LCM can be in the system, but must be compatible and well blended with the mud.
– Refer to Neyrfor Field Guideline 009 for a list of compatible LCM and their concentrations.
104
Incompatible LCM, foreign material, or excessive solids can become jammed in the running clearances of the blades and bearings, causing turbines to stall.

† Loads in excess of these limits could result in mechanical failure of body or shaft components. ‡ Transition is defined as the hole section in where the high DLS of the slide section to the
lower DLS of the straight section. The “transition zone” occurs with the initiation of rotation after completing a slide section.
§ The maximum recommended rotatable bend setting for a directional turbodrill is 1.8°.
