Regulator | Dynomax Drilling Tools

Real Innovation

Dynomax constantly strives to produce tools that meet today's challenges. With extended reach wells becoming more commonplace, the Regulator brings hole cleaning to the next level.

The Regulator has a proven history with multiple friction-reduction tools in both coil-tubing and conventional applications.

Today’s drilling applications are becoming more challenging with deeper, longer and more complex wells being drilled faster than ever before. One challenge is keeping the hole clean while drilling, which is achieved with higher flow rates. These flow rates are limited by the power sections on the motors and quite often lead to premature failure due to over-pumping.

The Patented Regulator^TM employs a variable size exit orifice to actively moderate the flow that goes through the motor continuously – extra fluid is vented out the side. The exit orifice is controlled by a valve that measures the flow entering the motor. The valve mechanism begins responding in milliseconds so that flow to the motor is always regulated.
