Processamento de Dados Sísmicos Reais da Bacia do Amazonas Utilizando as Migrações de Kirchhoff Pós e Pré-Empilhamento Em Tempo

Among the several problems in prospecting for oil and gas in the Amazon region, diabase sills occurring in the Amazonas Basin (Brazil), in spite of its role in the maturation of the organic matter that originated all hydrocarbons accumulations known so far, still poses difficulties for exploration seismic, causing anomalous seismic wave spreading, multiple reflactions and pull-up and pull-down effects, consequently rising the exploration risk. In this context, the present work then presents the results of conventional techniques: poststack Kirchhoff time migration and of modern techniques: prestack Kirchhoff time migration, seismic processing of the survey lines 0204-RL-0053, 0204-RL-0057 and 0204-RL-0058 acquired in the Amazonas Basin, with the objective of enhancing the seismic images of these cited sections.
