Abstract
A power charge and method for actuating a wellbore tool with a power charge. The power charge may include a first volume containing a first energetic material and a second volume containing a second energetic material positioned within the first energetic material. The second energetic material may be a faster burning material compared to the first energetic material. The wellbore tool may include a power charge cavity, an initiator positioned in an initiator holder adjacent to the power charge within the power charge cavity, and a gas diverter channel for directing to an expansion chamber gas pressure generated by combustion of the power charge, to actuate the wellbore tool. The method may include inserting the initiator into the intiator holder within the power charge cavity and initiating combustion of the first energetic material and the second energetic material.
