Abstract

Well tool packing element systems that do not require a back-up element or component include a mandrel (30), an upper supporting member (26), a lower supporting member (28), a cantilever element (22), and a ramp element (24) disposed on the mandrel. The cantilever element and ramp element are disposed on the mandrel with an interface angle between the cantilever element and the ramp element, the interface angle being less than 90 degrees, preferably in a range from 40 degrees to 60 degrees, and more preferably at an angle greater than 45 degrees. When an axial load is applied to upper and lower supporting members, cantilever element and ramp element are forced outward and into an inner wall surface of a casing to seal off the casing bore.
