Abstract
A system and method for performing stimulation operations at a wellsite having a subterranean formation with of a reservoir therein is provided. The method involves generating a plurality of quality indicators from a plurality of logs, and combining the plurality of quality indicators to form a composite quality indicator. The composite quality indicator may be combined with a stress log to form a combined stress and composite quality indicator, the combined stress and composite quality indicator comprising a plurality of blocks with boundaries therebetween. The method may further comprise identifying classifications for the plurality of blocks; defining stages along the combined stress and composite quality indicator based on the classifications; and selectively positioning perforations in select stages based on the classifications thereon.
