In this study information is included about the determination and the characterization of asphaltenes as it was published in the previous decades. Specifically, the purpose of the study is to collect and to give to the readers a general idea about the definition of the asphaltenes and their basic characteristics, as they have been determined by scientists from the middle ’19 century until now. Firstly, basic information is given about the properties of the asphaltenes and two approaches which are associated with asphaltene physicochemical behavior (solubility and colloidal approach) are also highlighted. Furthermore, the analytical methods and techniques which are used by scientists for asphaltenes detection and characterization are mentioned. Finally, two models that can determine the asphaltenes precipitation taking into account the prevailing experimental conditions and the thermodynamical effects in asphaltene are given.
