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.
