- Is Parasitic Torque Compromising Your Drilling Efficiency and ROP?
Overview
and can make high-angle or extended-reach wells undrillable without special measures.
Why It Happens
As well inclination increases, the drill string contacts the wellbore wall over a greater length and with greater normal force. Each contact point generates friction torque that accumulates along the string. In short-radius or through-tubing rotary drilling scenarios, these losses can consume the majority of available rotary torque before it reaches the bit.
How It Can Be Fixed
Install Paradigm’s Runner® torque and vibration reduction subs at strategic intervals in the drill string. The non-rotating outer sleeve lifts the pipe off the borehole wall and allows the string to rotate with minimal friction coefficient, reducing drilling torque by 25–40% and enabling consistent torque and ROP delivery to the bit.
Why Paradigm
Paradigm’s Runner® provides a direct, proven mechanical intervention against parasitic torque. It is effective for high-angle wells, short-radius designs, and through-tubing rotary drilling applications. Paradigm’s drilling optimization division offers both the Runner® product and complementary application-specific design and operational support services to engineer the optimum tool spacing and placement for each well.
