Abstract

"MéTODO PARA EXPLORAçãO SìSMICA UTILIZANDO SENSOR DE MOVIMENTO E DADOS DO SENSOR DE PRESSãO". A presente invenção refere-se a métodos para processamento de dados sísmicos adquiridos usando tanto sensores de movimento quanto sensores de pressão. é descrito um método para anulação de fantasmas e atenuação da reflexão do múltiplo da superfície da água nos dados sísmicos marinhos de sensor duplo. A anulação de fantasmas é executada transformando os dados no domínio da freq³ência espacial, e separando os componentes do campo de onda ascendente e descendente dos dados transformados. Além disso, é descrito um método para a exploração sísmica que inclui atuar uma fonte de energia sísmica em uma massa de água em uma pluralidade de posições. São medidos um parâmetro relacionado com a pressão e um parâmetro relacionado com um componente vertical do movimento da partícula. As medições do parâmetro relacionado com a pressão e parâmetro do movimento da partícula adquiridas em cada uma da pluralidade das posições de fonte são então decompostas em componentes de campo de onda ascendente e descendente, e um campo de onda substancialmente sem múltiplo é então determinado a partir dos componentes do campo de onda decomposto.
