Abstract

Se describe un método para calcular los datos sísmicos de fuentes de interferencia en la tierra que rodean un primer receptor sísmico y un segundo receptor sísmico. El método incluye el cálculo de una función de Green G'(X1, X2) entre un primer receptor sísmico X1 y un segundo receptor sísmico X2 usando la interferometría. El primer receptor sísmico X1 está ubicado a una distancia lejos del segundo receptor sísmico X2. Después de calcular la función de Green G'(X1, X2), el método puede incluir las etapas para determinar una cálculo de uno o más campos de onda no físicos presentes en la función de Green G'(X1, X2) y determinar un filtro para eliminar los campos de onda no físicos de la función de Green G'(X1, X2) con base en el cálculo de los campos de onda no físicos. El filtro entonces se puede aplicar a la función de Green G'(X1, X2) para obtener una función de Green G"(X1, X2) libre de campos de onda no físicos.
