It has been shown that the use of multiple seismic attributes enhances the rapid identification of anomalies and speeds up seismic interpretation, highlighting structural and/or stratigraphic features. The additive method RGB (Red, Green, Blue) is the most widely used, especially for spectral decomposition, which combines the primary colors. On the other hand, the subtractive method CMY (Cyan, Magenta, Yellow), that merges the opposites of the primary colors, cyan opposite to red, magenta to green, and yellow to blue respectively, is mainly used to highlight structural features by blending seismic structural attributes based on seismic amplitude, phase, and frequency. The resulting cube is essentially lighter, while the structural discontinuities and/ or faults are observed darker, in shades of gray and black and, consequently, their interpretation is more intuitive and agile for the interpreter. In the present work, an innovative methodology is proposed as a complement to the traditional seismic interpretation to contribute to the identification of anomalies and structural features in frontier exploration zones offshore Colorado basin of Argentina, including: 1) CMY subtractive blend of structural seismic attributes tensor, semblance, and dip to automatically perform structural analysis; 2) Blend of critical attributes, instantaneous frequency, envelope and dip, to highlight anomalies; and 3) Spectral decomposition to recognize stratigraphic features or potential contacts.
