study the complex interactions between oil, rock and water to deconvolute the mechanism governing low salinity reservoir flooding

Oil recovery is done by water flooding. Pushing water, typically seawater, through a sandstone reservoir can release upto 50% of the oil. To unlock the rest, intelligent changes has to be made to the injected water. Understanding the complex interactions between oil, rock and water is key to knowing what changes will be beneficial for the recovery. Lowering the salinity of the injected water is one such successful change, however understanding the full set of mechanism behind the increased release is still an enigma, but a full revelation of the mechanisms might lead to the ultimate water flooding.
