Houston, Texas – Schlumberger Limited, the world’s largest oilfield services company has launched its PowerDrive Orbit rotary steerable system (RSS), the company said in a news release.

The new RSS aims to expand the operating envelope of rotary steerable technology by extending system life, delivering precise directional control and increasing drilling efficiency.

The newly designed pad actuation system is combined with real-time, three-axis, shock-and-vibration measurements to withstand difficult drilling conditions at higher rotational speeds than conventional systems. Multiaxis continuous inclination and azimuthal gamma ray capabilities improve well positioning and enable self-steering for a smoother wellbore, the company said.

The PowerDrive Orbit RSS was field tested in more than 500 runs over two years in challenging onshore and offshore drilling conditions in regions that included the Middle East, onshore US, US Gulf of Mexico, Colombia, Mexico, China, Venezuela and the North Sea, the release said.

In the Middle East, a customer had a requirement to maintain directional control while drilling deep laterals in a challenging onshore oil well. The PowerDrive Orbit RSS drilled 3,868 m (12,690 ft) in a single run, extending the lateral length of previous wells by 33% and completing the operation 21 days ahead of schedule, the release said.
