AVO (amplitude-variation-with-offset) and Spectral Decomposition techniques were used together to enhance the difference between the gas sands and wet sands. The conditioning of the CDP gathers to preserve the amplitude was driven by the creation of the synthetic gathers in order to identify the type of AVO anomaly present. The CDP gathers then, were used in conjunction with the conditioned RMS velocity field, to produce the Intercept and Gradient AVO attributes and finally create their corresponding frequency gathers with the use of the spectral decomposition. The frequency gathers...
