| Isotropic | Spatial range corresponds to the size/shape of your main target structure: in the case of isotropic range, your structure has an approximately circular shape, with the same distance in every direction. Define Isotropic (X) spatial range values (meters / feet) based on analysis from your interpretation team and a priori geological knowledge about the subsurface. |
| Anisotropic | Spatial range corresponds to the size/shape of your main target structure: in the case of anisotropic range, your structure has an approximately ellipsoidal shape, with the two different distances in the two main directions, and, possibly, an azimuth. Define anisotropic (X,Y) spatial range values (meters / feet) based on analysis from your interpretation team and a priori geological knowledge about the subsurface. |
