Abstract:
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.
