  • Publication number: 20240418060
    Abstract: A perforation tool is described herein. The perforation tool has a charge unit comprising a shaped charge; an initiator attached adjacent to the charge unit and comprising a detonator disposed to energize the shaped charge; and a switch attached adjacent to the charge unit and disposed to apply a voltage to the detonator, the switch comprising a processing unit configured to receive data representing depth, compare the received data to a depth target, and apply the voltage to the detonator if the received depth indicates the depth target has been reached. The processing unit can be configured to receive any data that can be converted to depth or any data that can represent an activation condition and apply the voltage when the data indicates the activation condition has been met. The processing unit can be programmed to initiate and operate autonomously in a well independent of surface signals.
