There is more information in the seismic data than just Amplitude. A technique to extract more information is multiresolution analysis.
In this research, the Multiresolution Analysis (AMR) technique is applied in the domain wave number- space to 3D seismic data in the central Bolivian sub-Andean zone. Geologically the research is focused on deep studies around 4200 m (TVD), on the Robore sands (ArRob I, II and III) at levels of the Lower Devonian. The results, called k-anomalies, show an interesting relationship between long wavelengths and hydrocarbon reservoirs.
