Rotary steerable drilling technology made a dramatic entry into the market in the late 1990s. The technology has advanced considerably since then, offering increased flexibility, greater reliability and higher rates of penetration. These high-performance systems facilitate the drilling of complicated wellbore trajectories in harsh environments. With industry costs for nonproductive drilling time estimated at US$ 5 billion per year, rotary steerable systems are a key to preventing or reducing these significant losses.
adnVISION (Azimuthal Density Neutron), PERFORM (Performance Through Risk Management Process), PowerDrive, PowerDrive vorteX, PowerDrive Xceed, PowerDrive Xtra, PowerDrive X5, PowerPak, PowerPulse, PowerV and SlimPulse are marks of Schlumberger.
