Seismic data processing including data-constrained surface-consistent correction

Methods and systems for constraining surface consistent amplitude corrections are described. An amplitude map generated from pre-stack or post-stack seismic data can constrain, through the bin term, the surface consistent inversion.

description Methods and systems for constraining surface consistent amplitude corrections are described. An amplitude map generated from pre-stack or post-stack seismic data can constrain, through the bin term, the surface consistent inversion. The methods and systems provide a solution to correct for wavelength and regional anomalies associated with heterogeneous near surface or buried velocity variations above the target horizon. The methods and systems can be used for 2D, 3D, 4D surveys or for a merge of different surveys.
