Steerable Drilling Liner System

Increase drilling efficiency

Statoil and Baker Hughes Incorporated jointly developed the world’s first steerable liner while drilling system, successfully tested from the Brage platform in the Norwegian sector of the North Sea.

Working collaboratively with their combined experience and knowledge, the companies developed this innovative technology for applications in new and mature fields.

Eliminate the need to pull drillstring to run casing

Precise drilling and logging of 3D well profiles with a liner attached directly to the drillstring saves time and drilling costs by minimizing the risk of borehole collapse and reducing nonproductive time. The addition of rotary steerable capabilities helps drill complex well profiles while continuously rotating. Additionally, modular formation evaluation technology allows geologists to make critical real-time decisions while drilling through difficult zones.

Increase efficiencies with combined drilling and completion well construction

The successful Brage platform test involved the combination of our AutoTrak™ rotary steerable system, X-treme™ motors, EZCase™ casing bit system, and EZLine™ liner drilling system. Following a second deployment in January 2010 at Statoil’s Statfjord Field, the new technology will be commercialized.

AutoTrak X-treme

In 2005, Baker Hughes took the capabilities and design of the AutoTrak G3™ system and made one fundamental addition that changed everything: an advanced and proven motor technology. A pre-contoured stator design with an enhanced drive train created a powerful directional drilling machine: the AutoTrak X-treme™ rotary closed-loop system.
