Aplicação Da Decomposição Espectral De Dados Sísmicos No Estudo Das Acumulações De Hidratos De Gás Da Bacia De Pelotas

In the last years, seismic researches are producing more detailed and precise information for characterization and reservoir management. The spectral decomposition have been recently applied in seismic data as a powerful tool to interpret the properties of reservoirs, to determine the thickness of layers, to detect accumulations of hydrocarbon and to show stratigraphic details not visible in their original form. There are a lot of spectral decomposition methods that can be used but in this work we will apply the Continuous Wavelet Transform (CWT) in<br>seismic data of the Pelotas Basin to check how this technique responds to accumulations of gas hydrates in Brazilian coast.
