Abstract:
A time delay apparatus for use with a downhole tool in a wellbore casing. In an exemplary embodiment, the apparatus includes an electronic circuit comprising a timer, a fusible link, a split spool device that includes a center pin held in place in a restrained position with a spool and a spring element surrounding the spool. A pressure applied to a trigger device, such as a rupture disk, activates a pressure switch and starts a timer, configured with a preset countdown time, in the electronic circuit. On expiration of the timer, the timer block of the electronic circuit generates a signal to cause breaking of the fusible link and releasing of the spring element such that the center pin of the split spool travels to a functional position and activates the downhole tool.

Claim (Index 1):
A time delay apparatus for use with a downhole tool in a wellbore casing, the apparatus comprising:\n an electronic circuit having a timer configured to be programmed with a time interval; a trigger configured to activate the timer to commence a countdown of a programmed time interval; a fusible link configured to connect between a downhole tool activator and the electronic circuit, the fusible link degrading during a predetermined time period; wherein, upon activation of the timer in the electronic circuit, and expiration of the time interval of the timer, the fusible link commences degrading such that after the predetermined time period, the downhole tool activator is automatically triggered.
