Abstract

"FONTE SìSMICA E MéTODO DE OPERAçãO DA MESMA, MéTODO DE ELIMINAçãO DE FANTASMAS DE DADOS SìSMICOS, E ARRANJO DE PESQUISA SìSMICA MARINHA". Fonte sísmica marinha escalonada contém ambos arranjos, inferior e superior (10, 11), de emissores de energia sísmica (S11, S12e S21, S22). O arranjo superior (10) sendo horizontalmente deslocado em relação ao arranjo inferior (11) . A fonte é usada em um arranjo de pesquisa sísmica marinha tendo meios para movimentar a fonte e pelo menos um receptor sísmico. Em uso, a fonte se desloca na água em uma direção paralela, na qual os dois arranjos são dispostos. Os arranjos (10, 11) são disparados seq³encialmente, e o atraso de tempo entre o disparo do primeiro arranjo e o disparo do segundo arranjo é escolhido de modo que cada emissor sísmico em um arranjo seja disparado nas mesmas coordenas -x e -y que do correspondente emissor no outro arranjo. os campos de onda sísmicos gerados pelos disparos dos dois arranjos são gerados desta forma nas mesmas coordenadas -x e -y, mas em profundidades diferentes. Os dados sísmicos gravados no (s) receptor (es) resultantes do disparo do primeiro arranjo podem ser usados para eliminar fantasmas (de-ghosting) dos dados sísmicos adquiridos em conseq³ência do disparo do segundo arranjo ou vice-versa, assim eliminando ou reduzindo reflexões fantasmas ou reverberações
