Abstract
A downhole, hydraulically actuated drilling stabilizer 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 can also be used in a conventional rotary bottom-hole assembly or positioned below a steerable motor. A drilling stabilizer with adjustable extension diameters provides improved inclination control over currently existing options.
