    • The object of the invention is a process for the transportation of heavy oil whereby an oil-in-water emulsion containing an emulsifier, with at least 10-15% of water is transported and subsequently separated again into crude oil and water. The emulsifier employed is a carboxymethylated oxalkylate of the formulaR--(OCH.sub.2 --CH.sub.2).sub.n --oCH.sub.2 COOMand ether sulfate of the formulaR'--(OCH.sub.2 --CH.sub.2).sub.m --SO.sub.3 M'in which R and also R' mean a saturated or unsaturated linear or branched aliphatic radical with 8 to 20 carbon atoms, an alkyl aromatic radical with 4 to 16 carbon atoms, an alkyl aromatic radical with 4 to 16 carbon atoms or a di- or tri-alkyl aromatic radical with a total of 5 to 20 and 7 to 24 carbon atoms respectively in the alkyl groups, m means 1 to 40, n means 1 to 40 and M and M' mean an alkali or alkaline-earth metal ion or ammonium.
