    Аннотация Steam based-thermal methods for improving oil recovery mainly includes steam injection, steam-assisted gravity drainage (SAGD) and cyclic steam injection (CSS). One of main goal of these methods is to achieve in-situ upgrading of heavy and extra-heavy oil. The high content of high-molecular compounds like asphaltenes is the one of main problems that is need to be solved during the process of the upgrading of heavy oils. Therefore, studying changes in the structure and properties of asphaltenes induced by thermal treatment is currently an important task aimed at searching for optimum technologies of upgrading of heavy and extra-heavy oils. In this study, upgrading experiments were carried out in a stainless-steel 500-ml batch Parr reactor (4575/76 HP/HT Reactor) equipped with a heating mantle and a temperature controller. In a typical experiment, the reactor was loaded with crude oil and water at a weight ratio of 1:3, respectively. The reactor was heated at 5?C/min to 250?C, generating
