Abstract

a presente invenção refere-se a uma atualização de modelo de velocidade com um gradiente de inversão de forma de onda total. pelo menos um método pode incluir a atualização de um modelo de velocidade de uma subsuperfície, que pode incluir a supressão de componentes de número de onda alto do modelo de velocidade fornecido pela energia refletida com um gradiente de inversão de forma de onda total decomposto. os componentes de número de onda baixo podem ser preservados no modelo de velocidade.
