Prospecção sísmica das Bacias de Camamu, Almada, Jequitinhonha e Cumuruxatiba

Abstract

Considering that the seismic survey has shown to be a quite efficient geophysical method in the study of the geology in subsurface, mainly, with the objective of determining possible structures capable to store hydrocarbons. This monograph seeks to present a study about seismic survey accomplished in the last years in the basins of Camamu, Almada, Jequitinhonha and Cumuruxatiba. Firstly, it was made a geological description of the basins in study, presenting the crono-stratigraphical and structural evolution of them. Soon afterwards, it is described as the seismic acquisition is accomplished, in earth and in sea; showing how it is made each stage of the seismic processing, step-by-step, on the data. After these stages, the volume of data proceeds for the analysis of the interpreters. With the geological information at hands determine the petroleum system of each basin indicating the location of oil wells. ln this case, it is indispensable that a certain number of geological requirements happened simultaneously in the sedimentary basins. ln other words, the synchronism that makes the generating rock reservoirs, sealing, traps and migration originate and grow in an appropriate scale of time for the formation and accumulations of petroleum.
