Abstract

"MéTODO DE SEPARAçãO DE SINAIS DE MICROSSISMICIDADE DE SINAIS SìSMICOS EMITIDOS POR UMA OU VáRIAS FONTES". A presente invenção refere-se a um método para separar sinais de microssismicidade induzida de sinais sísmicos adquiridos no âmbito de operações de vigilância sísmica ativa de uma zona subterrânea em decorrer de exploração. São formados registros sísmicos a partir de sinais emitidos por uma fonte sísmica única ou várias fontes sísmicas comandadas por sinais ortogonais uns relativamente aos outros. Nessa alternativa os sinais são tratados para separar as contribuições respectivas das fontes sísmicas nos sinais recebidos e reconstruir os sismogramas equivalentes àqueles que seriam obtidos acionando-se para isso separadamente as fontes sísmicas. Separa-se os sinais de microssismicidade induzida (sísmica passiva) dos sinais sísmicos que emanam das fontes 5 (sísmica ativa) essencialmente isolando-se para isso a contribuição desses últimos, por comparação com um modelo espectral de referência nas freq³ências fundamentais emitidas e em seus harmónicos respectivos, e reconstituindo-se no domínio dos tempos os sinais de microssismicidade induzida e os sinais que emanam das fontes sísmicas 5. Aplicações na vigilância sísmica de reservatórios subterrâneos de hidrocarbonetos ou de estocagem de fluidos.
