Abstract
A power source for actuating a subsurface tool is described herein, the power source comprising thermite in a quantity sufficient to generate a thermite reaction, and a polymer disposed in association with the thermite. The polymer produces a gas when the thermite reaction occurs, the gas slowing the thermite reaction. The slowed thermite reaction enables a continuous pressure to be provided to the subsurface tool over a period of time, providing superior actuation over a conventional explosive power charge, through a non-explosive reaction.
