Abstract

Un metodo para procesar datos sismicos, habiendo sido obtenidos dichos datos sismicos efectuando una pluralidad de barridos, donde cada barrido comprende generar senales sismicas en la tierra, usando una pluralidad de vibradores, aplicando una forma de onda de barrido piloto a cada vibrador; siendo cada barrido piloto una forma de onda de frecuencia cambiante; midiendo la fuerza aplicada a la tierra por cada vibrador, para determinar una forma de onda de fuerza medida, y midiendo las senales sismicas en uno o mas sitios alejados de los vibradores; comprendiendo el metodo: filtrar la forma de onda de fuerza medida para eliminar las armonicas del barrido piloto y, de esa manera, determinar una forma de onda de fuerza filtrada; generar un operador de inversion a partir de la forma de onda de fuerza filtrada, para cada vibrador; y aplicar el operador de inversion a las senales sismicas medidas para determinar la contribucion de cada vibrador a las senales sismicas.
