Abstract:
Systems and methods for moving a tubular string within a subterranean well include 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 plurality of individual openings are spaced around an outer diameter surface of the structural ring, each individual opening associated with an inflatable member. The inflatable member is operable to vibrationally impact an internal surface of the subterranean well with repeated inflating and deflating the inflatable member. Wheels are spaced around an inner diameter surface of the structural ring.
