[54] SECONDARY SYSTEM AND METHOD FOR ACTIVATING A DOWN HOLE DEVICE
[57] Abstract: Disclosed is a secondary system and method for initiating a down hole operation in a wellbore when a primary activation system fails. The primary activation system is configured to provide fluid communication between a first chamber and a second chamber in response to a primary activation operation. The secondary activation system includes a passageway between the first chamber and the second chamber, and a rupture member positioned in the passageway. The rupture member has a threshold pressure differential at which the rupture member ruptures to afford fluid communication between the first chamber and the second chamber to thereby initiate the down hole operation if the primary activation system fails. The primary activation operation may be configured to move a trigger member to initiate the down hole operation, whereas the secondary activation operation may be configured to initiate the down hole operation without moving the trigger member.
