Abstract

um método inclui obter pelo menos uma forma de onda digital correspondente a sinais acústicos coletados por uma ferramenta de perfilagem implantada em um ambiente de fundo de poço. o método também inclui executar a análise espectral de frequência janelada (wfsa) na pelo menos uma forma de onda digital para obter informações de semelhança de frequência em diferentes fatias de tempo. o método também inclui derivar um perfil de lentidão em função da posição usando informações de semelhança de frequência.
