APS Technology announces successful first test of their Rotary Steerable System

Thursday, May 7, 2015

APS Technology, Inc. announced the successful first drilling test of its SureSteer 475-rss Rotary Steerable System. The tool was used to drill a directional borehole at the company's Wallingford, CT drilling test facility. Successful and consistent performance was observed while building and turning the well, with doglegs up to 6.5?/100 ft. Further drilling tests will be conducted in advance of anticipated availability of the tool in late Q2, 2015.

Designed for directional drilling applications throughout the world, APS SureSteer Rotary Steerable tools provide 'major service company' rotary steerable system functionality with the simple directional control commands commonly used with steerable motors.

Utilizing APS's proprietary control systems, they can be programmed to use an automated closed-loop feedback system for vertical or tangent angle control or to operate with surface-supplied instructions to efficiently drill any directional well plan. The 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 events such as wiper trips, drilling out or back-reaming. For steering, the desired tool face is set by surface orientation, similar to a steerable motor. This minimizes the amount of time required for downlinking. SureSteer tools have ample on-board computer power to enable much more sophisticated control. Direct linkage to APS MWD enables higher-level directional control and feedback of valuable near-bit information to the surface.

SureSteer Rotary Steerable tools are currently available for 8.5 in. or 8.75 in. (213 mm or 222 mm) holes. SureSteer 475-rss for 5.875 in. to 6.75 in. (149 mm to 171 mm) holes is planned to be available in Q2, 2015. Larger sizes will follow.

Complementary APS options for the SureSteer tools include a wide range of SureShot mud pulse or EM-based MWD and LWD tools; Drilling Dynamics Monitor (DDM), Vibration Memory Sub (VMS) and Vibration Memory Module (VMM) for downhole measurement of drilling mechanics and dynamics; Active Vibration Damper Sub (AVD) for real-time measurement and mitigation of drilling vibrations; and drilling optimization products including SureDrill and WellDrill.
