  • Systems and Methods for Modeling 3D Geological Structures
    Publication number: 20110205844
    Abstract: Systems and methods for modeling a three-dimensional (3D) geological structure to improve maximum continuity interpolation. An integration method describes local anisotropic effects and introduces interpolation techniques to perform the interpolation between two points of interest along a direction of maximum continuity and across fault surfaces.
