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.

A computer-implemented method for modeling a three-dimensional (“3D”) geological structure, which comprises:
- selecting input data for the geological structure;
- digitizing an image of the geological structure represented by the input data, the digitized image comprising multiple sample points;
- processing the digitized image using intelligent point densification to only initialize a location for each sample point and optimize each sample point location;
- calculating a structure and diffusion tensor field for the digitized image, each tensor for the tensor field being linked with a respective sample point at an optimized sample point location for the respective sample point;
- processing the digitized image using structure-oriented smoothing to form an enhanced image;
- calculating a fault displacement field for the digitized image using a computer processor;
- and
- interpolating the structure and diffusion tensor field, the enhanced image and the fault displacement field to produce a 3D geological model.
A non-transitory computer readable medium tangibly carrying computer executable instructions for modeling a three-dimensional (“3D ”) geological structure, the instructions being executable to implement:
- selecting input data for the geological structure;
- digitizing an image of the geological structure represented by the input data, the digitized image comprising multiple sample points;
- processing the digitized image using intelligent point densification to only initialize a location for each sample point and optimize each sample point location;
- calculating a structure and diffusion tensor field for the digitized image, each tensor for the tensor field being linked with a respective sample point at an optimized sample point location for the respective sample point;
- processing the digitized image using structure-oriented smoothing to form an enhanced image;
- calculating a fault displacement field for the digitized image;
- and
- interpolating the structure and diffusion tensor field, the enhanced image and the fault displacement field to produce a 3D geological model.
