A versatile Steerable solution for maximum build rate
Rotary Steerable System for Directional Drilling
The SureSteer™-RSS™475 rotary steerable tool was created to complement APS’s field-proven Rotary Steerable Motor (RSM®). Whereas the RSM incorporates an integrated power section designed to maximize horsepower at the bit, the RSS either runs below a drilling motor or is driven directly from the top drive to maximize build rate capability and drillstring speed.
The APS RSS is a modular design and is currently offered in two configurations; A 4.75” directional gamma RSS system utilizing a single collar assembly or a 2 part configuration for RSS with WPR, or higher LWD capability
Features & Benefits
- Can be programmed to use 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.
- Easily programmable downhole and straightforward to use. A series of timed pump speed changes allow for switching between modes or turning the tool off for events such as wiper trips, drilling out or back-reaming.
- Desired tool face on the initial unit is set by surface orientation (similar to a steerable motor), minimizing time required for downlinking.
- Desired build rate is communicated with timed pump speed changes.
- Can be directly linked to an APS MWD or LWD system for higher-level, comprehensive trajectory control, depending on the deployment method.
- Available tool sizes: 4.75 in. (121 mm) OD for 6.0 in. (152.4 mm) and 6.75 in. (171 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 an integrated turbine and alternator system.
- The control electronics provide timing signals to a hydraulic manifold to control the steering direction and force to achieve the desired directional objective.
- Maximize build rate and drillstring speed during directional drilling
