Abstract: A computer-implemented method for integrating a full wavefield inversion (FWI) solution with a non-FWI solution. Computational costs for generating a large bandwidth FWI solution, such as to 50 Hz, may be considerable. However, limiting the FWI solution to a narrower frequency band, such as up to 20 Hz, renders the FWI solution less useful. To remedy this, an FWI solution that is band limited, such as up to 20 Hz, is integrated with a non-FWI solution. The non-FWI solution may comprise seismic stacks or non-seismic data, and is directed to a different frequency band, with at least part of the non-FWI solution frequency band being greater than 20 Hz. In this way, bandwidth extension may be performed for at least one subsurface physical property parameter by combining a band limited FWI solution with a non-FWI solution.
