A downhole tool of this disclosure includes a set/reset ring located adjacent a gauge ring which is opposite at least one sealing member. The set/reset ring is arranged to move between an unset diameter at least equal to the unset diameter of the sealing member and a set diameter at least equal to the set diameter of the sealing member. The set/reset ring is like a coil spring having at least two full turns and, therefore, a 360° face surface when in its unset and set diameters. When a setting mandrel moves toward the sealing member, the sealing member moves to its set diameter and the set/reset ring moves into its set diameter. When the setting mandrel moves away from the sealing member, the sealing member returns to its unset diameter and the set/reset ring returns to its unset diameter.

Resettable element back-up system

Embodiments of a tubing anchor catcher includes a setting and a stationary sleeve each containing a set of spaced-apart cone pieces at one end that form a cone block configured to engage a set of slips. The anchor catcher, which may be designed for hydraulic or rotational setting, provides a reduced outside diameter that allows room for gas or debris bypass as well as capillary or electrical lines to be banded along the outside of the tool while providing a full open inside diameter. Because there is area available between the slips, multiple lines may be banded to the tool. In some embodiments, one of the raised slip protectors may include a line carrier sized to receive a capillary or electrical line.
