Seismic Anisotropic Advisor (seisSuperMan) Both seismic survey and well logs are Cartesian (x, y) coordinate system. However the some reservoir properties have preferred orientations. To study the anisotropic effects, the Support Vector Regression should be performed in the flow-oriented (s,n) coordinate systems. Usually the anisotropy settings include a ratio and angle setting. The ratio is the maximum range divided by the minimum range; the angle (0x01 graphic) is the orientation (s direction).
