Abstract
A chemical reaction heat source for use in heaters for downhole applications is provided. The heat source has a solid fuel composition that comprises thermite and a binding agent. The binding agent serving to maintain the solid form of the solid fuel composition during burning and ensure a predetermined uniform heating pattern can be provided for longer. The solid fuel composition can be provided in the form of blocks. The solid fuel composition can also be provided in the form of a plurality of fragments that, during burning, behave more like powdered thermite and have the ability to flow.
Claims8
A chemical reaction heat source for use in heaters for down-hole applications, said heat source having an inactive state and a reactive state, and having a solid fuel composition wherein the fuel composition comprises thermite and one or more binding agents that maintain the solid form of the solid fuel composition between said states wherein said solid fuel composition is provided in the form of a plurality of fragments, each of said fragments constitutes a reactive cluster that comprises various component parts of said fuel composition.
