downhole tool, method to act a downhole tool and system to act the downhole tool

摘要

a system and method for operating a downhole tool, where the tool can include a body, a closure element and a degradable actuation ring. an actuation ring profile can be configured to engage an actuation tool (for example, displacement tool, ball drop, dart, plug, etc.) used to move the activation ring through the hitch and thereby move the closing element to a different position. the degradable actuation ring can be degraded by a bore down agent to degrade and / or remove the actuation ring from the downhole tool, thereby providing a high clearance through the tool.
