Abstract

a presente invenção refere-se a uma técnica de aquisição sísmica que emprega um arranjo receptor e uma metodologia de processamento que são projetadas para atenuar o ruído sísmico de fundo gravado ao longo de dados sísmicos durante a aquisição. a técnica amplia o conhecimento de que ruídos de fundo naturalmente ocorrentes movem-se com uma velocidade de fase mais lenta do que sinais sísmicos utilizados para formar imagens e invenção e em algumas modalidades, pode chegar de direções particularmente preferidas. a técnica. a técnica conhecida compreende duas etapas 1) determinar a partir de ruído sísmico de fundo nos dados sísmicos preliminares uma faixa de velocidades de fase e amplitudes que contêm primariamente ruído e o grau do qual o ruído necessita ser atenuado, e 2) projetar um método de aquisição e processamento para atenuar o ruído relativo ao sinal desejado.
