AbstractAn aqueous composition containing an amine oxide surfactant, and preferably containing an amine oxide surfactant and enzymes, is added to crude oil, preferably by injecting the composition into the oil well, or adding the composition to pipelines or tankage containing the oil. An acid can also be used in conjunction with the composition. The composition acts to remove hydrocarbon contamination, from the well bore and mechanical components and further serves to break up the oil/water/sludge emulsion being delivered from the well head to facilitate separation of the oil. When used with an acid, the composition increases the effectiveness of the acid in removing inorganic contamination.
