Abstract
Un método para mejorar la estabilidad de una emulsión de agua en petróleo mediante el pretratamiento de por lo menos una parte del petróleo antes de la emulsificación. El paso del pretratamiento puede consistir en agregar polímeros al petróleo, biotratamiento de petróleo, tratamiento fotoquímico del petróleo, o combinaciones de estos métodos. Se puede utilizar la emulsión en varios métodos para recuperación mejorada de petróleo, inclusive como agente inyector para desplazar los hidrocarburos en la formación subterránea, y se puede utilizar la emulsión como fluido de barrera para desviar el flujo de fluidos dentro de la formación.A method to improve the stability of a water-in-oil emulsion by pretreating at least part of the oil before emulsification. The pretreatment step may consist of adding polymers to the oil, biotreatment of oil, photochemical treatment of the oil, or combinations of these methods. The emulsion can be used in various methods for improved oil recovery, including as an injecting agent to displace hydrocarbons in the underground formation, and the emulsion can be used as a barrier fluid to divert fluid flow within the formation.
