Abstract
The invention relates generally to rotary drilling equipment, and more particularly to stabilizers which are specifically adapted for use during directional drilling when only the drill bit is rotated using a down-hole motor, but which are also well suited for use during conventional drilling when the entire drill string is rotated. In a preferred embodiment, this is achieved by using three longitudinal ribs on the stabilizer body, one of which is displaced laterally in a down-hole direction and is radially oriented such that it contacts the low side of the borehole during directional drilling.
