Aquifers,which play a prominent role as an effective tool to recover hydrocarbon from reservoirs,assist the production of hydrocarbon in various *** so-called water flooding methods,the pressure of the reservoir is intensified by the injection of water into the formation,increasing the capacity of the reservoir to allow for more hydrocarbon *** studies have indicated that oil recovery can be increased by modifying the salinity of the injected brine in water flooding ***,various characteristics of brines are required for different calculations used within the petroleum ***,it is of great significance to acquire the exact information about PVT properties of brine extracted from *** properties of brine that are of great importance are density,enthalpy,and vapor *** this study,radial basis function neural networks assisted with genetic algorithm were utilized to predict the mentioned *** root mean squared error of 0.270810,0.455726,and 1.264687 were obtained for reservoir brine density,enthalpy,and vapor pressure,*** predicted values obtained by the proposed models were in great agreement with experimental *** addition,a comparison between the proposed model in this study and a previously proposed model revealed the superiority of the proposed GA-RBF model.
