SureSteer-RSM®

LEVEL THE PLAYING FIELD WITH PROVEN “PUSH THE BIT” TECHNOLOGY

APS’s SureSteer™ Rotary Steerable Motor (RSM®) combines an advanced-technology rotary steerable steering unit with a drilling motor power section. Using proven “Push-the-Bit” technology and designed with a very small auxiliary equipment footprint, the RSM provides rotary steerable control while continuously rotating the drill string with the optimum power and bit speed for the application.

The SureSteer-RSM675 is unique in that it can be configured to operate with various types of available power sections, from the traditional Rotary Steerable-compatible, low-speed variety all the way up to high-speed configurations to deliver the ideal bit speed for the drilling application.

Whereas the RSM is designed to maximize horsepower at the bit in downhole drilling applications worldwide, our Rotary Steerable System (RSS™) either runs below a drilling motor or is driven directly from the top drive to maximize build rate capability and drillstring speed.

APS’s RSM provides “major service company” rotary steerable system functionality with the simple directional control commands commonly used with steerable motors.

  • Provides “major service company” rotary steerable system functionality with the simple directional control commands commonly used with steerable motors.
  • Utilize APS’s proprietary control systems to use as a closed-loop feedback system for vertical or tangent angle control or to operate with surface-supplied instructions to efficiently drill any directional well plan.
  • Mode of operation may be easily changed downhole with a series of timed pump speed changes to switch between modes or to turn the tool off for back-reaming.
  • Desired tool face on the initial unit is set by surface orientation, similar to a steerable motor.
  • Desired build rate is communicated with timed pump speed changes.

  • Available tool sizes: 6.75 in. (171 mm) OD for 8.375 in. (213 mm), 8.5 in. (216 mm) and 8.75 in. (222 mm) boreholes sizes.
  • The steering head houses the steering pads; directional measurement and control electronics; and the electrical and hydraulic power systems, which are driven by the power section drive shaft.
  • The control electronics provide timing signals to a hydraulic manifold to control the steering direction and force to achieve the desired directional objective.
