摘要： A system and method for summarizing data corresponding to properties of interest on an unstructured grid that includes active cells and inactive cells on an output surface. An exemplary method comprises identifying an aggregation direction through a region of interest of the unstructured grid and identifying at least one active cell along the aggregation direction. The exemplary method comprises assigning an aggregated value for the at least one property of interest to a face of the output surface on a line along the aggregation direction based at least in part on the data corresponding to the at least one property of interest for the at least one active cell. The exemplary method further comprises filling the at least one data hole by identifying at least one face associated with an inactive cell on the line along the aggregation direction and assigning it an aggregated value.

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： Methods, systems, and computer-readable media for processing seismic data. The method includes receiving seismic traces representing a three-dimensional physical domain (602), and determining a partition of a similarity matrix based on a subset of the seismic traces (604). The method also includes determining a transition matrix based on the partition (608). The method also includes determining one or more eigenvectors and one or more eigenvalues (614), based on the transition matrix. The method includes calculating one or more approximated eigenvectors (620) for the similarity matrix, based on the partition, the one or more eigenvectors of the transition matrix, and the one or more eigenvalues of the transition matrix. The method includes assigning visual indicator values (622) to the respective seismic traces based on the one or more approximated eigenvectors, and causing a visualization of the three-dimensional physical domain to be displayed in a two-dimensional view (624), based on the one or more visual indicator values.
