Gradient of Texture

Salt domes are an important diapir shaped geophysical structures in the Earth’s subsurface that are impermeable and contain hints about petroleum and gas reservoirs. Therefore, determining the accurate location of the salt domes within migrated seismic volumes in one of the key steps in the exploration projects.

We proposed a novel seismic attribute three dimensional gradient of textures (3D-GoT) for delineating geophysical structures such as salt domes within migrated seismic volumes. The 3D-GoT computes an attribute map by measuring the dissimilarity between the neighboring cubes around each voxel in seismic volume across crossline, inline and time directions. The experimental results on real seismic data from the North Sea demonstrates that the 3D-GoT delineates salt domes with high accuracy and precision and outperforms the state of the arts methods of salt dome delineation.
