Thermal methods, in particular steam treatment, are the most needed among the tertiary methods of increasing the extraction of Heavy crude oil. The use of catalysts in couple with the steam injection is promising method. This article is about experimenting with the modelling of steam effects on the oil-saturated sandstone, using a dimensional-based catalyst based on iron. The composition and physico-chemical characteristics of the products of the thermocatalytic effects have been studied. It has been shown that th...

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...

In this research the regularities of heavy oil conversion in supercritical water and the presence of finely dispersed caustobioliths and metal oxides were shown. The process of thermo-catalytic conversion was carried out in a closed reactor under temperature and pressure conditions, providing the transition of the aqueous phase in supercritical fluid. To investigate the selectivity of catalysts, different compositions of catalyst systems were prepared and studied for their effectiveness in the process of degradati...
