An actuator, including a dynamic component, a static component. A seal is disposed between the dynamic component and the static component. A bypass pathway is open to flow dependent upon a position of the dynamic component relative to the static component, the bypass pathway when open changing a required flow rate to move the dynamic component relative to the static component. A method including applying a first pressure across a seal between a static component and a dynamic component, moving the dynamic component, opening or closing a bypass pathway with the movement, bypassing fluid when open whereby a higher flow rate is required to continue the movement of the dynamic component. A wellbore system, including a borehole in a subsurface formation, a string in the borehole, and an actuator disposed within or as a part of the string.

Actuator, method, and system

A backup includes an anchor portion, an operable portion extending from the tip of the anchor portion, and an S section having a curvilinear line therein and where a substantially constant thickness of material from the line to an inside surface of the S section and a substantially nonconstant thickness of material from the curvilinear line toward an outside surface. A backup system including a backup, a gauge ring engageable with the anchor portion, the gauge ring including a contact surface with a back angle configured to engage the S section when the backup is set. A seal system including a mandrel, a backup, disposed on the mandrel, a gauge ring disposed on the mandrel and configured to interact with the backup; and a seal element disposed on the mandrel.
