Steerable drilling liner service drills and evaluates wellbore while simultaneously installing a liner

HOUSTON -- Baker Hughes announced today the global commercialization of its SureTrak™ steerable drilling liner service, which is designed to drill and evaluate complex, 3D wells while simultaneously installing a liner. The service reduces the technical and economic risks associated with drilling and completing wells in low-pressure zones, unstable shale and coal layers, and formations with variable flows and pressures.

In conventional drilling operations, it is necessary to pull the drillstring before running the casing or liner into the borehole. The SureTrak service uses proven rotary steerable drilling and liner-drilling technologies, including the Baker Hughes AutoTrak™ rotary steerable system and modular logging-while-drilling and measurement-while-drilling systems, to drill, evaluate and install a liner to total depth in one run.

The SureTrak steerable drilling liner service—the first of its kind in the industry—was developed to address operational challenges such as narrow drilling margins, borehole collapse, and lost circulation safely and economically. The service enhances wellbore integrity and minimizes formation damage and, yet, does not require any special rig equipment.
