Paper Abstract

The asphaltenes flocculation process in heavy crude oils is a subject of great interest for the oil industry due to the negative effect of this process in the oil extraction. In this work we present the application of the Confocal Microscopy to the study of the aggregation process of asphaltene in crude oils. The advantages of the technique for study of the particles in surface and in the dispersed phase are shown. Confocal images of different shows changes in the behavior of the differents solutions. The results can be related with the stability and the prediction of asphaltene precipitation in crude oils.
