Abstract: A method is described for time-lapse seismic imaging that may include detecting moire patterns in seismic images generated from time-lapse seismic data and identifying geologic features based on the moire patterns. 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.
