Abstract: A wellbore reamer tool for use in downhole oil well operations includes two helical impellers, two cutting portions, and an integral blade stabilizer. The first helical impeller is positioned at a downhole end for cleaning the wellbore of formation cuttings in advance of reaming by the cutting portions, and directing the formation cuttings to a desired position on the first cutting portions. The first and second cutting portions include radially insertable cutter inserts having cutters for reaming the wellbore to yield the formation cuttings. An integral blade stabilizer is positioned between the cutting portions for supporting the tool while driving uphole flow of the formation cuttings. A second helical impeller is positioned above the second cutting portions for cleaning the wellbore and boosting newly incorporated formations cuttings uphole towards surface.

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.
