Abstract
A stabilizer for a drill string is disclosed. The stabilizer is of split configuration having an open slot or split which extends for the length of the stabilizer. The split stabilizer is slipped over a drill collar and fasteners are used to draw the split stabilizer together to clamp the stabilizer to the drill collar. The stabilizer may thus be positioned at any desired axial location on the drill collar and non-rotatably locked thereto by the fasteners. Advantageously, the stabilizer is made of a non-magnetic material.
