摘要： A method and system for modeling a subsurface structure at a time when the structure was originally formed. A first model having non-planar horizons representing a current subsurface structure may be used to calculate a vector field based on the non-planar geometry of the horizons of the model. The vector field may be non-uniform or uniform. Geographic coordinates of the first model may be transformed to paleo-geographic coordinates of a model representing the subsurface structure in the past, where the non-planar horizons in the first model are transformed to planar horizons in the second model. A set of points describing one or more fractures in the subsurface structure may be used to calculate a tuning parameter to correct a first set of paleo-geographic coordinates. A second set of coordinates representing an improved prediction at a time period when the subsurface structure was originally formed may be generated.

摘要： A method and system for computing and visualizing sedimentary attributes may include receiving, by a processor, paleo-geographic coordinates representing predicted approximate positions of particles of sediment deposited at a time period when a layer was originally formed. The processor may numerically compute or determine a sedimentation rate that varies laterally along the layer. The processor may determine a sedimentary attribute based on the lateral variation of the sedimentation rate along the layer with respect to the paleo-geographic coordinates. A monitor or display may display the sedimentary attribute of the layer in the present-day geological space.

摘要： A system and method may model physical geological structures. Seismic and geologic data may be accepted. A three-dimensional (3D) transformation may be generated between a 3D present day model having points representing present locations of the physical geological structures and a 3D past depositional model having points representing locations where the physical geological structures were originally deposited. An indication may be accepted to locally change the 3D transformation for a subset of sampling points in a first model of the models. The 3D transformation may be locally changed to fit the updated subset of sampling points. A locally altered or updated version of the first model and, e.g., second model, may be displayed where local changes to the first model are defined by the locally changed 3D transformation. The transformation may also be used to extract geobodies in the past depositional model.

摘要： A device, system and method for performing a 3D interpolation in a 2D interpolation stage and a 1D interpolation stage to generate a refined geological-time. A 3D model may be obtained of a subsurface region defined by an initial geological-time in the past when particles in the subsurface region are determined to have been originally deposited. The stages of the 3D interpolation may include a 2D interpolation along one or more initial 2D reference horizon surfaces to generate one or more reshaped 2D reference horizon surfaces, and a 1D interpolation based on the initial geological-time along one or more 1D interpolation lines to generate a refined geological-time, wherein each 1D interpolation line is approximately orthogonal to the initial 2D reference horizon surfaces. The 3D model may be displayed according to the refined geological-time.

摘要： A method of transforming an input stratigraphic grid SGrid which represents a region including one or more geological discontinuities is now disclosed. At least one target cell that is local to one or more geological discontinuities is transformed by displacing at least one target vertex of the target cell of the input SGrid in a selected direction that: i) is selected to approximate a local tangent of the reference horizon; and ii) is oriented from the target vertex to a representative manifold representing one of the geological discontinuities and/or an intersection between two or more of the geological discontinuities. A magnitude of a displacement by which the target vertex is moved is determined according to a non-Euclidian distance between the target vertex of the target cell of the input SGrid and the representative manifold.

摘要： 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.

摘要： 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.
