Abstract

"MéTODO PARA DETERMINAR A NATUREZA DE ESTRATOS ABAIXO DO LEITO DE MAR". Um método de processar uma resposta de campo de onda eletromagnética em operação de registro de leito de mar. O campo de onda é resolvido em componentes ascendentes e descendentes. O componente descendente representa as reflexões da superficie de mar, enquanto o componente ascendente representa as reflexões e refrações de estratos subterrâneos. O componente ascendente é então sujeito à analise.
