Coreflooding experiments were performed to study the effect of injected water salinity on oil recovery. The experiments were conducted at a temperature of 90C and a net overburden pressure of 1500 psi using Berea sandstone core samples and Arabian Light crude oil. Different concentrations of NaCl Brines (5500-200,000 mg/l), treated sea water, Wasia water, and 100,000 (mg/l) synthetic Arab-D water were used as displacement fluids. As a result of this study, it was found that oil recovery increases as the injected water salinity increases up to 100,000 (mg/l). Increasing the salinity beyond 100,00 (mg/l) did not give a significant increase in oil recovery. The increase in oil recovery was found to be supported by a decreasing the IFT as a function of water salinity up to 100,000 (mg/l), where the IFT started to increase slightly beyond this salinity. The realtive permeability ratio (Kro/Krw) was found to increase as the injected water salinity increases. The Compatibility tests conducted showed that when connate Arab-D water was mixed with sea water at 90C, calcium sulphate precipitated. However, analysis of the coreflooding effluents did not show any incompatibility problems due to injection of Wasia, and sea waters.
