Method for performing object-based connectivity analysis in 3-D seismic data volumes

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.
