Abstract
An oil recovery method by the modification of the rock wettability from hydrophilic to oleophilic using hydrophobic compounds. Specifically, the method relates to the application of oil-type emulsions in water based on hydrophobic compounds free of silicon and fluorine to increase the oil recovery in mature sandstone-type reservoirs after the injection of water.
