Abstract:

The extraction and transport of asphaltic crude oils are associated with high pumping costs because of high viscosity. It is necessary to implement different methods leading to decrease it. Chemical products allow energy saving compared with procedures of temperature increase. Experimental studies to analyze a viscosity reducer's influence is proposed, where the results achieved for one type of crude clarifying the chemical-physical mechanism associated. According to viscosity reduction, we see that the high viscosity in heavy crudes is due to forming a dispersed phase of asphaltenes. This paper aims to propose a mesoscopic model that describes the aggregate size behavior and the viscosity of the crude. The obtained model was used to theoretically and experimentally analyze different improvers' influence on an asphaltenic crude

Keywords:

Oil stochastic model, viscosity reduction, asphaltene aggregation.
