摘要： A method and system for generating a model function h(x,y,z) implicitly representing geologic horizons. Geological data representing a fault network and horizons automatically extracted from seismic data may be received. A 3D mesh may be generated and divided into a plurality of fault blocks by the fault network. A discrete function h(x,y,z) may be defined having values of the geological data representing horizons at discrete nodes of the mesh. Constraints may be installed on the discrete function h(x,y,z) defining surfaces representing horizons. Constraints may be installed on the discrete function h(x,y,z) to ensure the uniqueness of the function h(x,y,z). The discrete function h(x,y,z) may be interpolated at the nodes of the mesh to create a piecewise continuous function h (x,y,z) while honoring the constraints. The piecewise continuous horizon function h(x,y,z) may be synchronized across multiple fault blocks. A model of the piecewise continuous horizon function h(x,y,z) may be displayed.

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, apparatus and system for, in a computing system, perturbing an initial three-dimensional (3D) geological model using a 3D vector field. A coherent 3D vector field including 3D vectors may be generated where each 3D vector of the 3D vector field is associated with a node of the initial 3D geological model and has a magnitude within a range of uncertainty of the node of the initial 3D geological model associated therewith. The coherent 3D vector field may be applied to the initial 3D geological model associated therewith to generate an perturbed 3D model. The perturbed 3D model may differ from the initial 3D geological model by a displacement defined by the 3D vector field associated with nodes having uncertain values. The perturbed 3D model may be displayed.

摘要： A method, apparatus and system for, in a computing system, modeling a subsurface structure at a time period when the structure was originally formed. A memory may store a first model having a plurality of non-planar horizons representing a current state of the subsurface structure. A processor may compute a vector field based on the non-planar geometry of the horizons of the first model. The vector field may be a non-uniform vector field (e.g., the axe and/or co-axe vector field) or a uniform vector field (e.g., a global axis). Using the vector field, the processor may transform geographic coordinates of the first model to paleo-geographic coordinates of a second model representing a predicted state of the subsurface structure at a time period when the subsurface structure was originally formed, where the non-planar horizons in the first model are transformed to planar horizons in the second model. A display may display the first model.

摘要： 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. In a third embodiment of the invention, the isoparametric curves are characterized by defined mathematical relationships having a plurality of variables associated with at least the topology of the surface, and at least one of the variables is held constant between isoparametric curves. Preferably, each of the triangulations are characterized by vertices terminating at points on the surface, and the method further includes using the vertices to define a gradient of a mathematical function associated with the feature, which function is interpolated over the triangulated surface.
