  • Patent number: 9377546
    Abstract: Systems, methods, and computer-readable media for modeling a fracture network are provided. The method includes mapping a sub-seismic data set to a portion of a seismic-resolution data set, and defining a fractal region of the seismic-resolution data set containing the portion thereof to which the sub-seismic data is mapped. The method also includes generating a training image for sub-seismic scale characteristics of the one or more fracture networks of the seismic-resolution data set using the portion of the seismic-resolution data, and modeling the sub-seismic scale characteristics of the one or more fracture networks of the fractal region of the seismic-resolution data set outside of the portion, using the training image.

  • Publication number: 20140058713
    Abstract: The present disclosure describes a system, method and computer readable medium capable of extracting, characterizing and modeling fracture networks in a subterranean formation. In one embodiment, seismic data points indicating one or more discontinuities in the subterranean formation may be identified using processed seismic data and arranged according to a tree structure. In one embodiment, connection criteria and/or one or more user parameters may be utilized to identify and connect discontinuity points. In one embodiment, the connected discontinuity points may be utilized to generate discontinuity planes. In one embodiment, one or more of the extracted discontinuity planes may be characterized according to their directional characteristics, intersectional characteristics, shape, dipping characteristics, length/distribution, fracture density, and/or fault type. The extracted discontinuity planes may be converted from a seismic scale model into a sub-seismic scale model.

  • Patent number: 8639444
    Abstract: A method for performing chrono-stratigraphic interpretation of a subterranean formation. The method includes obtaining a seismic volume containing stratigraphic features of the subterranean formation deformed by structural events, performing structural restoration of the seismic volume to generate a restored seismic volume by removing deformation due to the structural events, performing a chrono-stratigraphic interpretation based on the restored seismic volume to generate chrono-stratigraphic objects each associated with a respective relative geologic age, and displaying the chrono-stratigraphic objects in a chrono-stratigraphic space according to the respective relative geologic age of each of the stratigraphic objects.

  • Publication number: 20130138350
    Abstract: A method for determining stratigraphic termination points from a seismic dataset, includes: deriving extremal surfaces from the seismic dataset, wherein the extremal surfaces include points that are each associated with at least one of a dip magnitude and a dip azimuth; selecting a subset of points on the extremal surfaces that meet a predetermined criterion; identifying, using a processor, a set of dip deflection points from the subset of points; defining a termination zone from the dip deflection points; defining extremal surfaces that are associated with the termination zone as associated surfaces; and determining the stratigraphic termination points based on the associated surfaces.
