The production of heavy oil has emerged as one of the great challenges of the oil industry today. The high viscosity, characteristic of these oils is linked to factors such as the presence of higher molecular weight components, asphaltenes, paraffins, resins and even due to emulsion stability. Highly emulsified oils are seen as a big problem because it directly affects the oil production and the costs involved to do it. Already the phase behavior of asphaltenes has been the subject of discussion in various jobs that match to recognize its complexity. Thus it is of utmost importance to develop new technologies that act reducing the viscosity and consequently reflecting in higher yields with lower costs. This study aimed to develop products that act reducing the viscosity, in operations where asphaltene dispersion and controlled droplet size of emulsified water from the system increased, so as to promote a significant reduction in viscosity with the use of environmentally products correct. A sample of oil used in the tests was from an exploratory field onshore Colombia. Products containing mixtures of different green chemical-polymeric agents with the intention of promoting a multifunctional and excellent synergy with the proposed system were developed. The analyzes were performed oil viscosity in a Haake RS 600, wherein the oil had its SARA and its water content measured by Karl Fischer. The results obtained with viscosity reduction were highly significant and promising, as the oil used in this study, no previous treatment had a viscosity of approximately 180000 cP, and after the development and application of the product is reached viscosities of up to 25 cP, while optimizing the process of demulsification end of oil.
