...-wet surfaces and the injection of water as a secondary recovery method may result in low oil recovery factors. The injection of low salinity brines has shown to be a method that can lead to significant additional oil recoveries, since they promote alteration of the surface wettability towards a more...

Abstract In this work, we present a multiscale approach based on first-principles calculations and classical molecular dynamics methods, to investigate the enhanced oil recovery via low-salinity water injection (EOR-LSWI). Salting-in effect, wettability, pH alteration, electrical double layer...

... the chemical composition of the injected water, tests performed in laboratory and in pilot units have shown significant oil recovery (5 to 40%), when compared with a field with traditional water injection. The oil industry has shown great interest in smart water (SMW). Basically, the SMW comprises a seawater...

... Abstract This work, is based on the multiscale coupling between molecular simulations and reservoir simulators, to explore the brine composition for enhanced oil recovery via the low salinity water injection (LSWI) processes. To achieve this goal, molecular simulations were performed, providing...

... Abstract Surfactant losses due to adsorption in the hydrocarbon reservoir is a major concern in surfactant based chemical enhance oil recovery (chemical EOR) methods because it results in the loss of optimum concentration required for adequately reducing oil-water interfacial tension (IFT...

... Abstract Polymer flooding is one of the well-established and commercially-available techniques for enhanced oil recovery in the petroleum industry. It is the most widely adopted chemical enhanced oil recovery technique in sandstones, but its application in carbonates is limited due to the harsh...
