Abstract
Systems and methods for moving a tubular string within a subterranean well include a ring assembly. The ring assembly includes a structural ring sized with a ring inner diameter to circumscribe the tubular string and a ring outer diameter to fit within a bore of the subterranean well. A rotatable blade extends from the structural ring. Wheels are spaced around an inner diameter surface of the structural ring.
