Abstract
A power charge and method for actuating a wellbore tool with a power charge. The power charge may include a groove formed in the outer surface of the power charge. The power charge may include a first volume containing a first energetic material and a second volume containing a second energetic material that is a faster burning material compared to the first energetic material. The wellbore tool may include a tool body wall defining a power charge cavity. The groove formed in the outer surface of the power charge may define a gas pressure path between the tool body wall and the power charge, within the power charge cavity, when the power charge is inserted into the power charge cavity. The method may include coupling an initiator to the wellbore tool and initiating combustion of the first energetic material and the second energetic material to actuate the wellbore tool.
