Patent number: 10795053Abstract: 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.Type: GrantFiled: October 29, 2014Date of Patent: October 6, 2020Assignee: EMERSON PARADIGM HOLDING LLCInventors: Jean-Claude Dulac, Wan-Chiu Li

Patent number: 10422923Abstract: A system and method for receiving data associated with a set of microseismic events and a fracture network, the data associated with each microseismic event including a location where, and a time when, the microseismic event was recorded by one or more sensors. Each microseismic event in the set may be added to a fracture network in chronological order of the time when the microseismic event was recorded. Each microseismic event may be added by connecting the event to the fracture network by a fracture according to a connection criterion. A stimulated rock volume may be generated that is defined by an iso-surface of points having a constant distance to the fracture network, wherein the fracture network includes a plurality of microseismic events in the set and a plurality of fractures connecting the plurality of microseismic events according to the connection criterion.Type: GrantFiled: September 12, 2014Date of Patent: September 24, 2019Assignee: EMERSON PARADIGM HOLDING LLCInventors: Alexandre Hugot, Jean-Claude Dulac

Patent number: 10339709Abstract: 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.Type: GrantFiled: June 27, 2018Date of Patent: July 2, 2019Assignees: Emerson Paradigm Holding LLC, Jean-Laurent MALLETInventors: Jean-Laurent Mallet, Jean-Claude Dulac, Emmanuel Labrunye, Christophe Winkler, Laurent Deny

Patent number: 10114134Abstract: A system and method for modeling a subsurface structure. Data representing a configuration of faults, horizons, and/or unconformities may be transformed to a depositional model comprising cells representing an estimated configuration of subsurface structure at a depositional time period when the subsurface structure was formed. Groups of cells in the depositional model may be divided into sub-meshes using iso-surfaces, where one set of iso-surfaces may represent the horizons at the depositional time period. The sub-meshes may be divided into one or more parts using the transformed geological data representing an estimated depositional configuration of the faults. For each group of cells in each sub-mesh part, the group of cells in the sub-mesh part may be represented by a single polyhedron. The polyhedrons may be transformed to generate a current model to represent the current configuration of the faults and horizons using transformed polyhedrons.Type: GrantFiled: April 27, 2012Date of Patent: October 30, 2018Assignee: Emerson Paradigm Holding LLCInventors: Wan-Chiu Li, Laurent Deny, Olivier Grosse, Jean-Claude Dulac

Patent number: 8635052Abstract: 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.Type: GrantFiled: June 7, 2010Date of Patent: January 21, 2014Assignee: Paradigm Ltd.Inventors: Jean-Laurent Mallet, Wan-Chiu Li, Jean-Claude Dulac
