Spectral decomposition is a method that transforms seismic data into the frequency domain, revealing geological features that may not be visible in conventional seismic interpretation. This technique is widely used in hydrocarbon exploration, reservoir characterization, and geohazard identification.
It enhances thin bed detection, allowing geoscientists to resolve thin reservoirs and stratigraphic layers beyond conventional seismic resolution. The method can also serve as a direct hydrocarbon indicator, detecting frequency anomalies associated with hydrocarbons. Lastly, it supports lithology and facies mapping by differentiating rock types based on their spectral response, making it a valuable tool in subsurface exploration and reservoir studies.
The Mixer in Petrel allows users to compare and evaluate multiple seismic frequency volumes simultaneously using RGB/CMY blending.
