Abstract: Intrinsic catalytic properties of mineral matrices of various natures (basalts, clays, sandstones) were studied, which are of interest for heavy oil upgrading in situ (i.e., underground) to create advanced technologies for enhanced oil recovery (EOR). The elemental, surface and phase composition and matrix particle morphology, texture and acidic properties were studied using elemental analysis, X-ray diffraction, high resolution transmission electron microscopy, IR spectroscopy, adsorption and desorption of nitrogen and ammonia. The data obtained on the catalytic activity of inorganic matrices to ammonium nitrate decomposition (reaction with a large gassing), oxidation of hydrocarbons and CO, and hydrocracking of asphaltenes into maltenes (conversion of heavy hydrocarbons into more valuable light hydrocarbons) were discussed. The matrices of basalt and clay natures were used as supports for preparing catalysts Fe/basalt, Ni/basalt, Fe/clay in order to check if they are appropriate for development of catalytic systems for asphaltenes hydrocracking. The catalytic activity of the matrices in the reactions of decomposition ammonium nitrate, oxidation of hydrocarbons and carbon monoxide, hydrocracking of asphaltens was observed for the first time.
