Enhanced bearing pack technology improves motor reliability

Increasing drilling efficiency and tool reliability are mandatory in the difficult economic environment and competitive marketplace. To meet these requirements, the industry demands new technologies to drive down break-even costs. To improve penetration rates, operators are selecting motor BHAs equipped with more aggressive bits that generate higher torque levels. The increased cutter count intensifies torsional loading on internal connections and bearing assemblies that can lead to premature tool failure.
