Ruggedized rotary steerable system
With an internal sealing mechanism, the PowerDrive Xceed RSS drills extended-reach wells through abrasive, soft, and hard formations.
The PowerDrive Xcel RSS was designed for use in high-profile directional drilling operations. In contrast with many RSS units, which rely on a magnetic and gravity field measurement for steering control in areas with high magnetic interference, such as drilling out of a whipstock window and close to offset wells or ferrous formations, the PowerDrive Xcel RSS provides inertial directional control in deviated sections. This feature, which can be toggled on and off by a downlink, enables tight directional control even through the magnetic zone-of-exclusion (ZOE). Its gyro can also be used as a redundant backup system to magnetic control. The PowerDrive Xcel RSS also has the ability to sense magnetic and inertial stick/slip as well as shock and vibration on three axes, enabling the tool to completely monitor downhole drilling for maximum drilling performance in any environment.
The system features automated closed loops for simultaneous inclination and azimuth and can be customized for ERD applications to optimize the curvature delivery and provide tighter control in long tangent sections. Reinforced critical components deliver greater durability for extended periods and through harsh environments. Evolving from one size fits all to an optimal configuration to maximize performance, PowerDrive Xcel RSS can be also configured to improve the curvature delivery in dogleg severity (DLS) assurance applications and to deliver on challenging environments. The PowerDrive Xcel RSS has a gamma ray sensor placed near the bit, which enables geostopping, early identification of zones of interest, and more accurate data that enhances real-time decision making.
Operator uses point-the-bit RSS to drill and log 2,000-m section in one run, offshore Russia.
Operator eliminates planned motor trip, mitigates risk of tracking casing, and drills section in one run.
Statoil ASA uses point-the-bit RSS's inertial steering mode to drill four sections in high-magnetic-interference environment without shutting in offset wells.
In any well delivery operation there are three drivers—drilling efficiency, accurate well placement and high-quality wellbores.
