ABSTRACT:
A bladed stabilizer including an upper body section having an upper annular flow area between the outside surface of the upper body section and the walls of the bore hole. The stabilizer further includes a lower body section wherein a plurality of blades are mounted for the purposes of reaming the hole. The outside diameter of the lower body section and the cross-sectional measurements of the welded blades combine to provide a net annular blade flow area between the lower body section and blades and bore hole which is greater than the flow area available past the upper body section so that flow past the stabilizer is maximized.
