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.
