Delivering more mechanical drilling power downhole than any other drive system, Neyrfor turbodrilling systems are ideal for drilling in harsh HPHT conditions and in the hardest, most abrasive formations. The systems are designed with a fully concentric drive-train rotation to maintain optimal power while on bottom and to absorb excessive loads for extended periods of time.
The drive system efficiently converts hydraulic energy from the mud column into mechanical energy at the bit to deliver more downhole mechanical drilling power. 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.
As a result of the high bit rotary speed, Neyrfor systems produce a consistently smooth wellbore. 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 system's consistent predictable toolface control, along with the use of stabilization, ensures that hole spiraling and microdoglegs are minimized. Toolface control also ensures that directional objectives can be achieved in even the most demanding environments.
Fit-for-purpose intervention mill coupled with a thru-tubing turbodrill milled for more than 100 h in temperatures up to 346 degF.
In a gas well where buildup had blocked access to a perforated interval, the operator successfully removed 206 ft of hard scale in the production liner.
