Abstract

MÉTODO DE LEVANTAMENTO SÍSMICO, E SISTEMA DE LEVANTAMENTO SÍSMICO. Uma técnica é projetada para realizar um levantamento sísmico. A técnica utiliza uma pluralidade de matrizes de vibrador empregadas para realizar um levantamento sísmico utilizando vibradores de alta frequência e de baixa frequência em cada matriz de vibrador. A pluralidade de matrizes de vibrador varre continuamente sinais de baixa frequência via vibradores de baixa frequência. Enquanto varrendo sinais de baixa frequência, vibradores de alta frequência emitem sinais de alta frequência em um padrão alternado entre matrizes de vibrador para intensificar o levantamento sísmico.
