Abstract

Volumetric flattening is a novel method for automatically flattening 3D seismic cubes that converts seismic volumes to volumes of horizon slices. With little or no effort, an interpreter can scan over the resulting horizon slices to see channels and other geologic features as they were laid down. Furthermore, the flattening transformation captures the shapes of all horizons in the cube. This transformation leads naturally to numerous interpretation applications ranging from isopach analysis to stratigraphic attributes. This algorithm is currently able to reconstruct across nearly vertical faults and incorporate hard constraints (such as manual picks and well ties). In summary, this data-driven method exploits the computer's ability to honor all of the data in all three dimensions to remap the data to a more geologically intuitive format.
