Abstract
The features of creating a procedure for surface-consistent amplitude correction using factors decomposition approaches are considered. The possibility of changing the models used is demonstrated, which makes it possible to choose the optimal models that have the best correspondence to the processed seismic material within the framework of the problem being solved. The effect of energy values related to different time intervals containing signals on the quality of the obtained factor estimates is studied. The procedure was tested on models and real data. It demonstrated the capabilities of the developed procedure and the correspondence of the results obtained by it to existing world-class software products.
