Today’s Drilling Challenges

As average well depths have increased over the past decade, directional and extended-reach drilling have become more commonplace. These wellbore trajectories, with their highly deviated paths (ERD) and associated increases in torque and drag, have exerted unprecedented force on the drill pipe, surpassing all previous stress level limits. These trajectories in turn, create severe wear conditions on both the casing and drilling string, which is becoming increasingly detrimental for drilling operations.
