Abstract

METODO PARA REDUCIR Y PREFERENTEMENTE PARA PREVENIR, LA PRECIPITACION DEL ASFALTO A PARTIR DEL PETROLEO CRUDO. POR UN LADO, EL PETROLEO CRUDO SE PONE EN CONTACTO EN EL POZO DE SONDEO CON AL MENOS UNA N,N-DIALKILAMIDA DE UN ACIDO GRASO CON DE 8 A 22 ATOMOS DE CARBONO. POR OTRO LADO, LA PRECIPITACION SE REDUCE DURANTE LA ANEGACION MISCIBLE EN UN PROCESO DE EXTREMO DE BOBINA (EOR) AÑADIENDO AL SOLVENTE DE ANEGACION AL MENOS UNA N,NDIALKILAMIDA DE UN ACIDO GRASO QUE TIENE DE 8 A 22 ATOMOS DE CARBONO.
