ABSTRACT:
A wellbore tool is provided to perform work in a wellbore by converting a chemical pressure source into a force exerted over a distance. The wellbore tool includes a pressure chamber sealed by a firing head and containing a power charge which includes a plurality of chemical components which are burned in a combustion reaction to generate gas. The combustion reaction of the power charge is initiated by a resistance heater which directly initiates the combustion reaction by receiving electrical energy and generating heat. The combustion reaction generates gas within the pressure chamber, the gas having a pressure which pushes a pressure responsive member into movement relative to the pressure chamber for providing a force over a distance to operate a downhole tool.
