Abstract

La presente invención se refiere a un procedimiento para preparar un aditivo de óxido de hierro de gran área de superficie para lodos de perforación, acuosos, destinándose el aditivo para secuestrar los sulfuros presentes en la formación y obtenido de los residuos de la clacinación de la pirita de lecho fluidizado, sometiendo la fracción del residuo con un tamaño de partícula de entre 0.074 mm y 0.037 mm (malla de 200 y 400) a separación magnética, con lo que se obtiene una fracción magnetica útil para la invención y una fracción no magnetica rechazada. El aditivo de magnetita tiene una área de superficie de 2.9 a 3.3 m cuadrado/g y, cuando se incorpora a los lodos de perforación, no cambiará sus propiedades reológicas, aún si se usa en grandes cantidades.
