Industry: chemical industry, oil industry
The present invention relates to cocogem surfactants for an enhanced oil recovery process, said surfactants exhibit reduced critical concentration for micelle formation and thermal stability under conditions typical of deeper oil storage layers (e.g. higher temperature, pressure and/or salinity) as compared to the prior art. Furthermore, said cocogem surfactants provide reduced water-to-oil interfacial tension as compared to the prior art. The invention also relates to a process for producing said cocogem surfactants.
