Claims
- 1. A method for predicting connectivity of seismic objects determined from seismic data collected from a subterranean region, said method comprising the steps of:
a) dividing said subterranean region into cells and determining from said seismic data the value of a pre-selected seismic attribute in each cell; b) choosing a threshold criterion for the value of said seismic attribute; c) determining for each cell in said subterranean region whether the value of said seismic attribute satisfies said threshold criterion; d) identifying seismic objects containing only connected cells that satisfy the attribute criterion, using a pre-selected definition of connectivity; e) repeating steps b-d for at least one different value of said attribute value threshold; and f) tracking each identified seismic object for changes in its size, spatial position, and connections to other seismic objects, all as a function of attribute threshold value.
- 2. The method of claim 1, wherein the results from step f are used to predict connectivity of geologic features in said subterranean region.
- 3. The method of claim 1, wherein all seismic objects defined in step d smaller than a pre-selected minimum size are discarded from consideration.
- 4. The method of claim 1, wherein all seismic objects defined in step d larger than a pre-selected maximum size are discarded from consideration.
- 5. The method of claim 1, wherein a 3-D visual display is used to present the results in step d, thereby aiding said tracking in step f.
- 6. The method of claim 1, wherein a 2-D hierarchical tree display is used to graphically depict the results of step f.
