The spectral attributes from synthetic forward model were analyzed. The analysis result reveals that the reservoir thickness and reflectivity series are the first-order factors to control the spectral decomposition response. The spectral anomalies of the gas-associated reservoirs can occur at low-frequency sections or high-frequency sections. The systematic synthetic model was developed on the basis of reservoir properties. This model can provide information about the properties of spectral attributes for the special reservoirs and is helpful in selection of the optimal frequency range in the reservoir fluid detection.
