Changes in Stability of the Heavy Crude Oil from the Usinskoye Oil Field in the Course of Development of the Deposit by Methods for Enhancing Oil Recovery

摘要

It is found out that the treatment of reservoir oil with gel-forming and oil-displacing compositions results in changes in aggregative stability of produced oil. The results of the study of oil samples from the Usinskoye oil field show that the highest increase in oil stability is exhibited by samples after their treatment with an oil-displacing composition based on surfactants.
