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 (</em><em>₀</em><em>) 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.</em></p>coefficient of difference of physical properties of oil and waterfluid-oil factorfinal mobility coefficientкоэффициент различия физических свойств нефти и водыжидкостно-нефтяной факторкоэффициент конечной подвижности
