The article presents the results of approbation of the methods of determining the coefficient of difference of physical properties of oil and displacing agent (0), proposed by Lysenko V.D. on the example of the Kalamkas field. Determination of this parameter is necessary for designing and improving the development based on direct oilfield data. The coefficient of difference between the physical properties of oil and the displacing agent (0) was determined by several methods, which showed high convergence, thereby confirming the theoretical validity in practice. The presented methods were successfully applied for the first time on the example of the Kalamkas field.
