Abstract: Process for water-wetting oil-wet surfaces by applying an aqueous formulation comprising at least one wettability modifier which is a water-soluble ester of an alkoxylated saccharide to the oil-wet surface. The oil-wet surfaces may be any hydrophobic surfaces such as the rocks of subterranean oil-bearing formations.

Abstract translation: 通过将含有至少一种润湿性改性剂（其是烷氧基化糖的水溶性酯的润湿性改性剂）的水性制剂施用于油润湿的表面，来进行水润湿油润湿表面的方法。 油湿表面可以是任何疏水表面，例如地下含油层的岩石。
