摘要： A computer-implemented method of determining a search expression describing a feature of interest in a set of data points distributed throughout a geological object is provided. Each data point contains a value for a geological attribute at that point. The search expression has a plurality of entries. The method including the steps of: (i) displaying the geological object using display codings corresponding to value subranges for the geological attribute such that all data points which have values for the geological attribute falling within a given value subrange are displayed with the same coding; (ii) selecting a plurality of data points of the feature of interest; and (iii) allocating value characters to entries of the search expression, the value characters corresponding to the value subranges for the geological attribute of the selected data points.

摘要： A system and method may, based on a 3D seismic data set seed point, execute a seed picking algorithm, using the first point for picking a set of second points from the data set, setting each of the points in the set of second points as the first point and repeating the algorithm. An iteration number or other attribute may be assigned to the points, the iteration number corresponding to the number of times the algorithm repeated to process the point. The attribute or a number of attributes may be displayed as a visual characteristic for each point. An iterative process may be applied to a set of seismic data points, starting at a seed data point and finding a set of next iteration seed points from among the set of points neighboring the seed point, continuing only with next iteration seed points, and recording for each of a set of data points the number of points that are found by the process when the point is used as a seed data point. Attributes may include, for example, the total number of descendants of a seed point, the direction, for example, the azimuth, of propagation of the horizon picking process, or information that relates to the order in which points are picked such as an iteration number.

摘要： A method can include transmitting a call to a GIS; receiving a response; transmitting search criteria to a search engine based on the response; and receiving search results. A method can include orienting a plane in a view; constructing rays from the plane to a surface in the view; determining a 2D extent based on intersection points of the rays and the surface; transmitting the 2D extent; and responsive thereto, receiving information. A method can include receiving image data for a 2D extent; defining a 2D grid for the 2D extent; generating a texture by assigning the image data to the 2D grid; generating a 3D grid by sampling elevations of a surface and assigning them to the 2D grid; applying the texture to the 3D grid; and rendering the 3D grid with the applied texture.

摘要： Analysis of a seismic event, such as a microseismic event caused by hydraulic fracturing, comprises measuring seismic waves emitted by the event and converting the measurements into two values for magnitude of explosion or implosion and for magnitude of displacement discontinuity at a plane, together with two directions, a direction of a normal to the plane and a direction of displacement; where the two values and the two directions compose the moment tensor describing the seismic event. The measurements may be converted into the moment tensor and decomposed into the values and directions. The values and directions associated with several seismic events may be displayed concurrently on a graphic display as a graphic representation of multiple events, where each event may be depicted with magnitude of expansion or contraction represented by a volume and the plane represented as a laminar object.

摘要： One exemplary embodiment presents a unified approach in the form of an Interactive "Visulation" (simultaneous visualization and simulation) Environment (IVE) designed to efficiently segment geologic features with high accuracy. The IVE unifies image structure analysis and implicit surface modeling as a surface-driven solution that assists analysts, such as geoscientists, in the segmentation and modeling of faults, channels, and other geobodies in 3-D data, such as 3-D seismic data.

摘要： A suite of processes and tools for preprocessing data prior to seismic interpretation including: voxel connectivity mapping, seismic response reduction, voxel suppression and voxel density. Voxel connectivity is used to assist with removing insignificant data. Seismic response reduction is used to reduce the seismic response of a given reflector to a lobe, such as a main lobe. Voxel suppression assists with highlighting and enhancing lithologic boundaries to aid in human and computer-aided interpretation. Voxel density scores the local significance of data trends within a volume, such as a 3-D seismic volume, to assist with the enhancement of these trends.

摘要： An apparatus and method are disclosed for enhancing the combined image of multiple attributes without compromising the image of either attribute. The combined image of the multiple attributes is enhanced for analyzing a predetermined property revealed by the attributes. The combined image can be interactively manipulated to display each attribute relative to an imaginary light source or highlighted using a specular component. The method and apparatus are best described as particularly useful for analytical, diagnostic and interpretive purposes.

摘要： A system and method is provided for quickly tracking a physical phenomena represented within the three-dimensional volume data set. A plurality of planes may be successively displayed in the three-dimensional volume data set from which points are digitized related to the structure of interest to create a spline curve on each plane. The area between the spline curves (1914, 1916, 1918, 1920) is interpolated to produce a surface (1912) representative of the structure of interest, which may for example be a fault plane described by the three-dimensional volume data set. In this manner, the user can more easily and effectively visualize and interpret the features and physical parameters that are inherent in the three-dimensional volume data set.

摘要： A model is created by distributing a plurality of points in the volume in the absence of a grid. Each point has a location. A first vector, having a length, a magnitude representing the value of the geological property in the neighborhood of the first point, and a direction representing the direction of maximum continuity, derived from a geological property in the neighborhood of the location of the first point, is assigned to a first point of the plurality of points. The direction of maximum continuity is the direction along which the magnitude of the geological property stays substantially the same for the greatest distance when moving away from the first point. The length of the first vector represents the distance from the first point in the direction of the first vector that the magnitude and direction of maximum continuity of the geological property stay substantially the same.
