As a promising alternative to thermal steam treatment of oil-saturated reservoir technology to intensify the extraction of heavy oil catalytic aquathermolysis process can be identified. This paper presents the results of research of the active form oil soluble catalysts based on metals Co (II) and Fe (II), formed in the process of the laboratory simulation of catalytic aquathermolysis heavy crude oil, and its influence on the composition of the oil itself. Experimental data shows a decrease in viscosity catalytic aquathermolysis products. According to the hydrocarbon type content analysis (SARA) and IR spectroscopy a significant reduction of high-molecular structures of oil by catalytic thermal destruction was revealed. The composition of the active form of the catalyst powder was analyzed by X-ray diffraction method. It was shown, that the oil soluble complex based on Co is converted to the sulfide form, the complex based on Fe - to the oxide. According to the results of SEM measurements of the catalyst, the particle size is within 60 nm
