Summary:
In this abstract, we propose a multiscale approach for enhancing the resolution of instantaneous attributes, such as cosine of phase and phase dip, both of which tend to be highly sensitive to noise in seismic data. In particular, we use a multiscale representation, namely the Gaussian pyramid, to exploit seismic features at different resolutions followed by multiscale fusion to enhance both the quality and reduce noise sensitivity of these attributes. The value of the proposed technique is demonstrated through application on the Netherlands offshore F3 block, indicating its potential for improving more seismic attributes, such as coherence and curvature.
