Abstract

The effect of Enhanced Oil Recovery (EOR) system in the laboratory on the composition of highviscosity and heavy oils from the oil fields of Russia, Germany and Mongolia was investigated. It is shown that thermal treatment and influence to the components of the EOR system causes a significant change in the composition and properties of the investigated oils. The content of low molecular weight n-alkanes in the treated oils was increased 2.5 times. Viscosity of oils was reduced almost three times, the amount of oxygen-containing compounds and total acid number of oils has also declined
