Abstract:
A method for suppressing noise in a common depth point gather of seismic data traces is disclosed in which noisy data traces are detected and muted by a sequence of data processing steps prior to making a final stack of the data traces.

Abstract:
In accordance with the present invention, there is disclosed herein a method of seismic interpretation that is designed to improve the quality and speed with which an explorationist can pick and interpret a seismic section or volume. The instant invention utilizes unseeded picking to create a collection of patches or areas of similar-character reflector picks. The method is unsupervised initially and builds an output database that preferably contains the time and amplitude of each âassignedâ event, an assigned event being a seismic reflection that is determined to be similar in some sense to its neighboring traces. Then, during subsequent interpretation the explorationist quickly builds an interpretation by utilizing and selecting from the pre-assembled collections of similar traces stored in the database.

Abstract:
A method for recognizing and comparing features of attribute data expressed in a 3D data survey involves: extracting, mapping, color coding and displaying 3D data for at least one attribute. Preferably, the data is based on tomographic paths. The tomographic paths are defined within a subvolume of instantaneous attribute data having the shape of a sphere. This is accomplished by extracting the subvolume of attribute data having a desired shape, defining multiple tomographic paths extending from a point within the subvolume to its bounding surface, combining instantaneous attribute values encountered along each of the tomographic paths to determine multiple aggregate values, mapping the thus determined aggregate attribute values on the surface of the sphere using a color code, and displaying the color coded sphere. The attribute maps are correlated with preexisting geological or stratographic templates to identify features.

Method Of Predicting Rock Properties From Seismic Data
A computer-implemented method of predicting rock properties of a subsurface formation using reflection seismic data and well log data. Synthetic seismic data is generated from the well log data and quantized into discrete synthetic data subcells based on rock property-predictive seismic attributes of the synthetic seismic data. The reflection seismic data is also quantized into discrete reflection data subcells based on the same seismic attributes used to quantize the synthetic seismic data. Each reflection data subcell is correlated with a corresponding synthetic data subcell based on the seismic attributes of the reflection and synthetic seismic data. A statistical distribution of well log properties associated with the synthetic seismic data subcells is then assigned to corresponding reflection data subcells, which can be viewed as 2D seismic lines, 3D seismic volumes, or single data point histograms.
Method And Apparatus For Interactive Curved Surface Borehole Interpretation And Visualization
An enlarged computer graphic image of borehole data is displayed on a concave three-dimensional surface, preferably a semi-cylindrical shape. Thus providing an enlarged image of a borehole surface where the data is spatially correct in three-dimensions, and which increases the ease with which interpreters can locate geological features such as surfaces, faults, and fractures.

Abstract:
A system for filtering elevation-sensitive data. The system generates coincident contour and attribute maps of a physical structure. A filter band that is limited to a certain range of contour values is used to filter the attribute values that are output to a CBA attribute map. The filter band applied to the data is defined between upper and lower boundaries, with each boundary having a substantially constant contour value. Thus, each data point has a uniquely-shaped a real filter that is at least partly defined by the filter band.
