  • Publication number: 20080243454
    Abstract: Embodiments of the invention provide a system and method for partitioning data for modelling a geological structure including laterally partitioning the data into multiple columns, where each column may be substantially laterally centered about a dual fiber and vertically partitioning each column at each of multiple intersection points of multiple surfaces and the dual fiber about which the column may be substantially laterally centered.

  • Publication number: 20080021684
    Abstract: The invention concerns a method for building a three-dimensional (3D) cellular partition covering a 3D geological domain by defining the cells of the partition, characterized in that said method comprises the following steps A “3D screen construction step” for constructing a 3D screen which is a 3D elementary partition covering the geological domain, said 3D screen being composed of a plurality of voxels (Vi) which are elementary volume elements, A “voxel painting step” for associating a cell identifier (Cell-id) to each voxel, A “cell definition step” for defining the cells of the geological domain, each cell of the geological domain being defined as the subset of voxels of the 3D screen associated to the same cell identifier, thereby allowing the definition of the cells of the geological domain without having to code the geometry and/or topology of said cells in said geological volume.

  • Publication number: 20050228623
    Abstract: A process for stochastic simulation of ancient riverbeds or ancient geological structures includes the following stages: (a) parameterize the geological reference horizon by linking to it a two-dimensional parametric system of paleogeographic coordinates; (b) construct a modeling function, the isovalue curves of which are approximately parallel to the general direction of the ancient riverbed to be simulated; (c) use the absolute value of the modeling function of the general direction of the ancient riverbed to be located in order to define a topographic function of the pseudo-valley; (d) transform the topographic function of the pseudo-valley by using a transfer function to determine the thicknesses, dimensions and characteristics of the ancient riverbed to be located and/or the ancient geological structures associated with this ancient riverbed.

  • Patent number: 6820043
    Abstract: A method of establishing continuity of a property which is interpolated over a surface defined by at least two primary nodes. The method includes identifying first and second portions of a boundary which defines a discontinuity in the surface. The method further includes defining the first and second portions of the boundary by at least one secondary node on each portion, and interpolating the property from a first primary node to a second primary node by utilizing the secondary nodes. When the property is characterized by determined values at primary nodes on the surface, the continuity of the property can be established as substantially the same value of the property at the selected secondary nodes. When the surface is characterized by a given gradient at each of the secondary nodes, the continuity of the property can be established as substantially the same gradient at the selected secondary nodes.

  • Patent number: 6300958
    Abstract: Methods and apparatus for mapping a feature onto a simulated surface having contoured portions, the surface being definable by a plurality of generally adjacent triangulations, the surface being further definable by a plurality of intersecting isoparametric curves linking identified values of the feature to identified points on the surface. In one embodiment, the isoparametric curves are characterized in that when the surface is flat, the isoparametric curves intersect one another in a perpendicular manner, and the perpendicularity of the intersections on the contoured portions of the surface is maintained. In another embodiment, the isoparametric curves are characterized in that when the surface is flat. The isoparametric curves are spaced a predetermined distance apart, and the spacing of the intersections on the contoured portions of the surface is maintained.

  • Patent number: 5465323
    Abstract: A method for obtaining a model of a surface including the steps of obtaining measurements of geometrical data concerning specific points on the surface, making a grid of the surface, with the grid passing through said points, memorizing, at an address which is specific to each node of the grid, the coordinates of the node, the number of satellites of the node, information for access to the addresses of said satellites and thereafter to information which relates to them, and geometrical data which may be associated with said node; for each node, defining a local roughness index obtained from a weighted sum of the current coordinates of the node and its satellites, defining the sum of an overall roughness index representing the sum of all the local roughness indices, and of an overall index of the infringement of said geometrical data, iteratively adjusting the coordinates of indefinite nodes, by using at each adjustment the sum of a weighted combination of current node neighbor coordinates and of a combination
