Abstract
Un método para emplear una formulación surfactante en la recuperación de petróleo mejorada por productos químicos, en el cual dicha formulación surfactante comprende por lo menos: i) una sal aniónica de un alquil sulfato alcoxilado, donde dicho alquil sulfato alcoxilado tiene una estructura molecular expuesta en la fórmula [1] en la cual R es un grupo alquilo lineal, ramificado, o mezcla de lineal y ramificado que contiene de 10 a 20 átomos de carbono, n = 4 - 15, m = 0 - 10, M⁺ es un ión de metal alcalino, un ión de alcanolamina, un ión de alquilamina o un ión amonio y ii) un etoxilato de alcohol no iónico, donde dicho etoxilato de alcohol tiene una estructura molecular expuesta en la fórmula [2] en la cual R¹ es un grupo alquilo lineal, ramificado, o mezcla de lineal y ramificado que contiene de 8 a 24 átomos de carbono, y = 20 - 100.
