Abstract: A method is described for property estimation including receiving a seismic dataset representative of a subsurface volume of interest and a well log from a well location within the subsurface volume of interest; identifying seismic traces in the seismic dataset that correspond to the well location to obtain a subset of seismic traces; windowing the subset of seismic traces and the well log to generate windowed seismic traces and a windowed well log; multiplying the windowed seismic traces and the windowed well log by a random matrix to generate a plurality of training datasets; and training a neural network using the plurality of training datasets. The method may be executed by a computer system.

Abstract: A method is described for seismic imaging that may include receiving a partially flattened seismic image representative of a subsurface volume of interest; detecting moire patterns in the partially flattened seismic image; quantitatively characterizing the moire patterns; calculating flattening corrections based on the quantitatively characterized moire patterns; applying the flattening corrections to the partially flattened seismic image to generated a new flattened seismic image; and identifying geologic features based on the new flattened seismic image. The method may be executed by a computer system.

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.
