Abstract: The core of the technology resides in the reduction of oil viscosity and the respective production rate increase under the condition of oil layer heating. It is known, for example, that the heating of the layer with heavy oil up to 100°C theoretically leads to a 15 to 20 times production rate increase. The technology works on the principle of controlled automated continuous pumping of highly exotermic chemicals into the bore hole through separate channels. Reaction runs mostly in a productive layer and the well itself is cooled by chemicals and is not damaged. The decomposition of chemicals releases huge amounts of gases, what creates long and wide fractures. Heating of 1 cubic metre of formation by 100 K gives 1 cubic metre of oil. The technology can be used efficiently on heavily watered oil wells especially when air is used for slow oxidising of oil and supercritical conditions of water are reached.
