Abstract
La presente provee una formulación de tensioactivos para utilizar en el tratamiento y la recuperación de fluido fósil desde una formación subterránea. La formulación de tensioactivos incluye un tensioactivo no iónico, ácido orgánico -seleccionado entre ácido cítrico, ácido diglicólico, ácido glicólico y una de sus sales- y agua para inyecciones. La formulación de tensioactivos puede inyectarse en uno o más pozos de inyección situados dentro de la formación subterránea y luego, a partir de uno o más pozos productores, pueden recuperarse fluidos fósiles.
