  • Patent number: 10795053
    Abstract: A system and method for modeling a geological structure may include, in an initial model, computing a first function for a geological structure including a first set of iso-surfaces. A processor may detect if the first set of iso-surfaces intersect a set of geological markers within a threshold proximity. If not, the initial model may be corrected using an induced mesh having an increased cell resolution compare to the initial model for computing a second function for the geological structure including a second set of iso-surfaces that intersect the geological markers within the threshold proximity. A processor may insert the second set of iso-surfaces into a second model to locally increase its resolution relative to the initial model by dividing cells in the second model along the second set of iso-surfaces. For each new geological structure, the above steps may be repeated using the second model as the initial model.

  • Publication number: 20200225383
    Abstract: A system and method is provided for restoring a 3D tomographic model of the Earth's subsurface geology from the present-day to a past restoration time. Whereas at the present time all faults represent active discontinuities, at a past restoration time some faults have not yet formed. Accordingly, the restored model divides the fault network into ?-active faults (discontinuous surfaces for faults that intersect the layer deposited at the past restoration time) and ?-inactive faults (continuous surfaces for faults that do not intersect the layer deposited at the past restoration time). A new 3D restoration transformation is also provided that uses linear geological constraints to process the restoration model in less time and generate more accurate geological images.

  • Patent number: 10466388
    Abstract: A method for editing a volume-based model imaging geological structures. An initial volume-based model comprising a volumetric mesh and updated geological data defined within a region of the model is received. The volume-based model is decomposed by converting the volumetric mesh into surface meshes linked by stratigraphic fibers to generate a surface-based model. The defined region of the surface-based model is edited by editing positions of control nodes of the surface meshes along the stratigraphic fibers in the defined region of the model so as to fit the updated geological data. The plurality of stratigraphic fibers are updated based on the edited positions of the control nodes so as to fit the updated geological data. The edited surface-based model is meshed to generate an updated volume-based model comprising a volumetric mesh defined by the edited positions of the control nodes. The updated volume-based model is stored and/or displayed.

  • Patent number: 10345467
    Abstract: A system and method for modeling seismic data using time preserving tomography including storing an initial set of parameter values representing an initial seismic data model. The initial seismic model may correspond to at least two or more ray pairs. Each ray pair may have a traveltime. An altered model may be generated by altering two or more parameter values in the initial set of parameter values for each of two or more ray pairs in the initial model. Altering one parameter value without altering the remaining of the two or more parameter values may correspond to a change in the traveltime of each of the ray pairs, while altering the two or more parameter values in combination typically corresponds to no net change in the traveltime of each of the ray pairs.

  • Patent number: 10338252
    Abstract: 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.

  • Patent number: 10339709
    Abstract: 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.

  • Patent number: 10310137
    Abstract: 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.
