Abstract
Se relaciona con un proceso para recuperar hidrocarburos de una formación subterránea mediante la inyección de una emulsión dentro de la formación. Mas especificamente, la emulsión se estabiliza por medio del uso de partículas sólidas no disueltas y puede utilizarse para desplazar los hidrocarburos de la formación o para producir una barrera que desvie el flujo de fluidos en la formación. Se puede adicionar a la emulsión dióxido de carburo u otro gas para ajustar la viscosidad de la emulsión al nivel deseado.It is related to a process to recover hydrocarbons from an underground formation by injecting an emulsion into the formation. More specifically, the emulsion is stabilized through the use of undissolved solid particles and can be used to displace hydrocarbons from the formation or to produce a barrier that diverts the flow of fluids in the formation. Carbide dioxide or another gas can be added to the emulsion to adjust the viscosity of the emulsion to the desired level.
