X-treme Series Motors

Maximize ROP in challenging wells

Our Navi-Drill™ X-treme™ Series motors withstand the toughest drilling conditions, maximize rates of penetration (ROP), and offer performance unattainable with conventional motors. Their design produces unprecedented torque and power levels, reducing cost-per-foot in harsh environments. Easier steering and high weight-on-bit (WOB) capacity with aggressive polycrystalline diamond compact (PDC) bits maximize penetration.

The motors’ precontoured stator increases mechanical and hydraulic efficiency, enabling more than 1,000 hp at the bit. Manufacturing processes match drive train and steering performance, reducing failure.

Minimized stator elastomer content enables hotter hole deployment with greater chemicals tolerance in aggressive drilling fluids.

Built for performance

These motors are built into our real-time drilling technology, including the Baker Hughes AutoTrak X-treme™ service, CoilTrak™ coiled-tubing bottomhole assembly system, and TruTrak™ service.

The newest in the X-treme series, the X-treme eXtend™ high-performance motor, provides higher power output and reliability for drilling challenging hole sections that have proven to be difficult for conventional motor technologies. The unique design of the motor’s power section enables its use in higher temperatures, and the power output of the motor provides optimal ROP, lowering drilling costs.

For high-torque drilling in straight-hole, tangent, extended-reach or horizontal sections, the medium-speed X-treme motors’ precontoured stator maximizes ROP. The motors are optimized for typical flow rates and medium bit rotation speed characteristics. The motors provide up to 100% greater torque than typical conventional motors, ensuring reservoir access through long, hard, and abrasive horizontal sections.

The X-treme™ LS low-speed motors have larger chamber volumes with similar configurations to yield high torque with lower bit speeds. They’re ideal for high WOB requirements.

X-treme™ RF motors address performance drilling in top-hole sections with PDC bits. High ROP occurs at reduced flow rates and rotary speeds that are typical on low-specification rigs.

Our X-treme™ HS high-speed motors have a precontoured stator in a ½-lobe configuration with speed to 1,185 RPM. With equivalent turbine bit speed, these motors offer higher torque and WOB. In abrasive formations, these motors with impregnated drill bits optimize ROP.

Drill efficiently

Our Navi-Drill™ Ultra X-treme™ motors have shorter power sections that drill a complete well profile. This includes shorter radius profiles to enhance lateral reservoir exposure.

A shorter power section increases efficiency and drills higher dogleg severity in shorter radius profiles. It drills ahead after passing through curves that are too tight for conventional power sections. Evaluation sensors are closer to the bit for precise reservoir navigation and wellbore placement in demanding applications.

The intermediate radius motors’ high-strength material offers flexibility while drilling curves up to 70°/100 ft. They accommodate severe conditions in intermediate-radius drilling.

Rotary Steerable Systems

Our rotary steerable and automated systems have precise steering controls for exact wellbore placement to maximize production.
