Abstract: A method is described for seismic imaging that may include receiving digital seismic data; processing the digital seismic data to create a digital seismic image in a seismic domain; flattening the digital seismic image to generate a digital flattened image; identifying artifacts in the digital flattened image; transforming the artifacts back into the seismic domain; and reprocessing the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts. The method may be executed by a computer system.
