Abstract

"MéTODO DE MONITORAçãO DE FONTE SìSMICA USANDO ASSINATURAS DE FONTE MODELADA COM FUNçõES DE CALIBRAGEM". A presente invenção refere-se a parâmetros físicos para um conjunto de fontes sísmicas, preferivelmente para cada ativação das fontes sísmicas. As funções de calibragem são obtidas e os parâmetros físicos medidos e as funções de calibragem são aplicadas a um modelo que gera uma assinatura de fonte calibrada para o conjunto de fontes sísmicas. Alternativamente, os parâmetros físicos medidos são aplicados a um modelo, o que gera uma assinatura de fonte modelada e, então, as funções de calibragem são aplicadas a uma assinatura de fonte modelada para gerar a assinatura de fonte calibrada. Alternativamente, as assinaturas de fonte modeladas são geradas para cada fonte sísmica e, então, as funções de calibragem são aplicadas a uma assinatura de fonte modelada para gerar uma assinatura de fonte calibrada para cada fonte sísmica. Então, as assinaturas de fonte calibrada para cada fonte sísmica são combinadas, preferivelmente por meio de superposição linear, para gerar a assinatura de fonte calibrada para o conjunto de fontes sísmicas.
