Well-Guide RSS™

The Well-Guide RSS™ is a fully closed-loop, automated Rotary Steerable System available in two sizes for holes from 8 3/8 to 17 1/2 inches. Well-Guide uses 'point-the-bit' steering to produce a smooth borehole and maximize drilling efficiency.


Rotary Steerable Cross-Section

    Operating Principles
    • A rotating shaft is positioned within a non-rotating housting by means of bearings and actuators.
    • With information from directional sensors, an on-board computer calculates a toolface and the transmission shaft is automatically deflected in the required direction by means of the system's actuators.
    • The curvature developed by Well-Guide defines the borehole curvature.
    • Automatic closed-loop control in both inclination and azimuth provides an accurate borehole profile with minimal surface intervention.
    Control Features
    • Continuous steering while rotating:
      - Accurate borehole of low tortuosity
      - Less torque drag
    • Drilling course can be changed at any time:
      - Accurate well placement
    • Turn rate can be adjusted at any time:
      - Accurate well placement
    • Directional sensor close to bit:
      - Accurate control
    • Can be steered to a gravity force:
      - Steers in areas of magnetic interference
    Mechanical Features
    • Bearings and mechanisms do not see drilling forces:
      - Reliable and long life
    • Bearings and mechanisms operate in lubricating oil:
      - Reliable and long life
    Drilling Features
    • Steers a conventional rotary drilling assembly:
      - Maximizes reach
      - Maximizes hole cleaning
      - Reduces possibility of stuck pipe
    • Can simultaneously underream/hole open:
      - Cost saving
    • Can be used below a motor:
      - Faster drilling
    • Any MWD/LWD can be used:
      - Operator has free choice
    • Operates in any formation:
      - Completely versatility
    • Operates in any fluid medium - mud/foam/air:
      - Complete versatility
