Abstract:
Disclosed is a chemical system of gas evolving oil viscosity diminishing compositions (GEOVDC) for stimulating the productive layer of an oil reservoir, that is to chemical compositions for a thermochemical treatment of an oil reservoir, more specifically for initiating a chemical reaction in the productive layer zone of the oil reservoir to produce heat and evolve gases so that the extraction of oil (petroleum) is improved. Further disclosed is a method of thermochemically treating an oil reservoir by means of this chemical system, and an apparatus for performing thermochemical treatment of an oil reservoir.
