| 20110203797 | GAS EVOLVING OIL VISCOSITY DIMINISHING COMPOSITIONS FOR STIMULATING THE PRODUCTIVE LAYER OF AN OIL RESERVOIR - The invention is directed to 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. The invention is further directed to a method of thermochemically treating an oil reservoir by means of this chemical system, and to an apparatus for performing thermochemical treatment of an oil reservoir. | 08-25-2011 |
