Embodiment Construction

[0032] A combination ("composite") is created by combining one or more attributes into a single combined attribute body or composite. In one example related to seismic attributes within a 3D volumetric dataset, certain data values ​​(typically having 256 possible values ​​in a seismic attribute 3D volumetric dataset) are represented by other spatially consistent seismic attribute data values This is accomplished by substituting certain values ​​for another data value (such as an 8-bit seismic marker data value). Compositions are particularly useful for enhancing the performance of voxel-based automatic tracking devices. Examples highlighting the utility of combinations for applications in decoding seismic data include seismic amplitude / instantaneous phase combinations for automatic tracking of low-amplitude discontinuities. An event means a geobody such as a geological structure described by seismic data. In another example, a seismic amplitude / similarity combination may be ...

Abstract

A method and system are disclosed for creating a combination attribute volume or compbo volume by combining one or more attribute volumes into a single volume. For instance, seismic data volumes may be used for creating a combination seismic attribute volume from multiple seismic attribute volumes. This is accomplished by replacing certain of the standard 8-bit data values in a seismic data volume with marker values that denote certain other values of other, spatially coincident, seismic attribute data. The resulting combo volume may then be displayed and a seed pick positioned on an event ofinsertest such as a geological body. An auto-picker function or program will then find all the connecting points which will quickly further define the event. The event may then be displayed and interpreted.

Description

technical field [0001] The present invention generally relates to imaging of three-dimensional ("3D") volume data sets. More specifically, the present invention relates to improved imaging and analysis of physical properties representing events in 3D volumetric data sets. Background technique [0002] Analysis and imaging of 3D volume data sets are required in many research fields. For example, in the medical field, computed axial tomography ("CAT") scanners or magnetic resonance imaging ("MRI") equipment are used to generate images of parts of a patient's body or diagnostic images. A scanner or MRI device produces a 3D volumetric data set to be imaged or displayed so that medical personnel can analyze the images and make a diagnosis. [0003] Three-dimensional volume datasets are also used in many fields of research involving the earth sciences. Seismic sounding is a method used to explore the earth's subsurface geology. Subterranean blasts or earthquakes excite seismic...
