Annotation:
The authors of the article consider colloidal and thermodynamic aspects of asphaltenes precipitation and their practical use in the Arctic deposits conditions. The influence of low temperatures and high pressure on asphaltenes stability is considered as well as the application of the Hildebrand solubility parameter and the Gibbs equation for predicting the conditions of their precipitation. The authors of the article present experimental results obtained in the course of modeling conditions typical for arctic zones and offer recommendations for preventing asphaltenes precipitation, being important for oil production optimization in difficult conditions.
