Abstract

A downhole, hydraulically actuated drilling stabilizer that provides versatility in a bottom-hole assembly. The drilling stabilizer can be used in a directional drilling application to help control the inclination in an extended reach or horizontal well. The drilling stabilizer has stabilizer blade members with an angular design portion that provides versatility in a bottom-hole assembly. The stabilizer could also be used in a conventional rotary bottom-hole assembly, or positioned below a steerable motor.
