FIELD: oil and gas industry.
SUBSTANCE: salts obtained by saponification of carboxylic acids contained in vegetable oils are used as organic acid salts and inorganic salts of molybdenum, tungsten, chromium are used as water-soluble inorganic metal salts. The invention also relates to methods (alternatives) of catalyst use which is that the catalyst is dissolved in a solvent and injected into the reservoir layer, wherein in order to intensify the catalyst action it may be applied in combination with heating of the catalyst target object - heavy hydrocarbon raw material.
EFFECT: reduced viscosity and increased flow of oil-in-place, increased profitability of the process of oil production and handling, extended list of purpose catalysts.
