Abstract

Patente de Invenção "PROCESSO EM UMA OPERAçãO COLETORA DE CAMPO DE ONDAS MULTICANAL". A presente invenção apresenta um processo para examinar a geometria da disposição de uma pluralidade de fontes (18-24) e receptores (10-16) através de uma área a ser prospectada tendo em vista otimizar a rede para evitar zonas de sombra de dados e otimizar a imagem sísmica resultante. O processo depende do estudo da distribuição estatística de polaridade de pendentes em escaninhos de pendentes ao longo de azimutes CMP selecionados.
