Halliburton GeoPilot RSS System Guidelines
Halliburton's Geopilot RSS rotary steerable system also uses "point the bit" technology. The design concept involves the deflection of a flexible shaft between the drilling bit and the drill string. A high-side reference housing contains a compact and rugged computer-controlled bias unit (eccentric rings) to impart a controlled deflection to this shaft element, allowing for continuously variable - both in tool face and effective bend angle - steering.
