    摘要： A method and system are described for creating a subsurface model. In this method, a watertight framework may be adjusted to lessen the ill-formed mesh elements. The method collapses mesh elements and/or eliminates nodes enhance the watertight framework and subsequent subsurface model. The resulting subsurface model may be used in reservoir simulations and hydrocarbon operations.

    摘要： Geologic modeling methods and systems disclosed herein employ fault face parameterization to constrain and improve the transformation of a faulted physical space geologic model into an unfaulted depositional space geologic model. An illustrative embodiment includes: associating a seismic image with each face of at least one fault in a subsurface region; determining a correspondence map between the seismic images for said at least one fault; parameterizing the faces using the correspondence map to match parameter value assignments for corresponding portions of the faces; creating a displacement map that draws together matching parameter values to align the corresponding portions of the faces; applying the displacement map to the geologic model to create a design space model; modifying the design space model; applying the displacement map in reverse to the modified design space model to obtain a modified geologic model; and outputting the modified geologic model.

    摘要： Method and system is described for modeling one or more geophysical properties of a subsurface volume. The method includes extracting locations from the data volume and combining them into an object, for example a horizon. The extraction may begin with selecting one or more initial traces, assigning labels to each sample of each trace, selecting a propagation pattern, and propagating the labels from the initial traces along a vector volume. Then, locations with the same label are extracted (1106). As an alternative to label propagation, a specific type of labeled volume (1102) may be obtained, such as a stack of surfaces (1132). The object may then be further modified or utilized to enhance the process of producing hydrocarbons.

    摘要： Method for segmenting a geophysical data volume such as a seismic data volume (10) for ranking, prioritization, visualization or other analysis of subsurface structure. The method takes any initial segmentation (11) of the data volume, and progressively reduces the number of segments by pair combination (13) so that an optimal stage of combination may be determined and used for analysis (15).

    摘要： Method for generating a new family of seismic attributes sensitive to seismic texture that can be used for classification and grouping of seismic data into seismically similar regions. A 2D or 3D data analysis window size is selected (23), and for each of multiple positions (25) of the analysis window in the seismic data volume, the data within the window are transformed to a wavenumber domain spectrum (26). At least one attribute of the seismic data is then defined based on one or more spectral properties, and the attribute is computed (28) for each window, generating a multidimensional spectral attribute data volume (29). The attribute data volume can be used for inferring hydrocarbon potential, preferably after classifying the data volume cells based on the computed attribute, partitioning the cells into regions based on the classification, and prioritizing of the regions within a classification.
