US Patent 11401762 Roll-out apparatus, method, and system

A roll-out apparatus, method, and system is disclosed for deployment in a subterranean well at a setting location. The roll-out apparatus, method, and system includes a load ring and an energizing ring. The load ring may include an outer surface having an outer circumference and a slot extending through the entire wall thickness that follows a circuitous path from a front face to a back face of the load ring. The energizing ring includes an outer surface configured to contact an inner surface of the load ring to enlarge the outer circumference of the load ring in a radial direction. This causes the outer surface of the load ring to seal to an inner surface of the subterranean well at the setting location.
