Abstract:
A stabilizer for passing through a restriction includes a tubular body having a bore therethrough; a rigid blade disposed on the tubular body; and a deformable blade disposed on the tubular body, wherein the deformable blade includes a geometric profile configured to preferentially bend the deformable blade in one direction when the deformable blade encounters the restriction, and wherein the deformable blade has a height greater than a height of the rigid blade. In one example, the deformable blade is offset from a radial axis.
