Abstract

A drill string stabilizer includes an elongated tubular body (T) having a circumferential, radially extending enlargement (E) between the ends thereof. First and second groove means (20, 21) are provided in the enlargement with the first groove means (20) inclined in one direction and the second groove means (21) inclined in the other whereby the first and second groove means intersect to form opposed fluid flow paths in the well bore adjacent the stabilizer to assist in maintaining the drill string on course. <IMAGE>
