Abstract

Métodos y dispositivos que utilizan técnicas de FWI mejoradas para la exploración sísmica de formaciones subsuperficiales que incluyen cuerpos de sal, con el uso de una función de costo de tiempo de desplazamiento. En el cálculo de la función de costo de tiempo de desplazamiento, los desplazamientos de tiempo se pueden ponderar con el uso de coeficientes de correlación cruzada de los respectivos datos registrados desplazados en tiempo y los datos sintéticos generados con base en el modelo de velocidad actual. Los métodos mejorados mejoran la imagen resultante mientras que se evitan los saltos de ciclo y los problemas relacionados con la diferencia de amplitud entre los datos sintéticos y registrados.
