Comparative analysis of physical and chemical prorerties of oils from various deposits

This article cites the results of a research of fundamental physico-chemical parameters of oil from Kashagan and Martishi. The main physicochemical characteristics of oil are given, including the pour point, kinematic viscosity, fractional composition, the content of mechanical impurities, salts and sulfur in oil from the Kashagan and Martishi fields. On the basis of the conducted research, it was concluded that the oil of both fields is in accordance with the main state-of-the-art physical and chemical indicators. A comparative analysis of the properties of oil from two fields was carried out. Comparison of the content of oil salts from two fields showed that the content of salts in oil from the Martyshi field exceeds this indicator in the Kashagan field, but also corresponds to GOST.
