This paper presents the results of research of the influence of the rock-forming minerals on the decomposition temperature of the oil-soluble catalyst precursor in the process aquathermolysis of heavy crude oil. As the catalytic agent was used nickel tallate, which in the process of aquathermolysis of heavy oil is converted into an active form. Changes in the composition of heavy oil after aquathermolysis in the presence of a precursor catalyst were evaluated using the hydrocarbon type content analysis (SARA). In ...

The depletion of light hydrocarbon resources and increasing the amount of heavy oil reservoirs drive petroleum companies to produce high viscous oil by unconventional methods, particularly thermal methods. Presently increasing the efficiency of thermal applications is a vital task. This paper discusses the influences of catalytic (introduction of catalytic precursors and H donor with amount of 1 wt% on oil) and non-catalytic aquathermolysis to the group composition and properties of extra-heavy oil from ?Ashalchin...

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 ...
