SYSTEM AND METHOD FOR PERFORMING DOWNHOLE STIMULATION OPERATIONS Russian patent published in 2018 - IPC E21B44/00 E21B43/26 G06G7/50 G06F17/50 

FIELD: soil or rock drilling; mining.

SUBSTANCE: group of inventions relates to methods for performing stimulation operations at a wellsite having a subterranean formation with of a reservoir therein. 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. Plurality of stress blocks may then be merged using diversion criterion. Composite quality indicator may be combined with the merged stress blocks to form a combined stress and composite quality indicator, comprising a plurality of blocks with boundaries therebetween. Method may further comprise defining stages along the combined stress and composite quality indicator based on the diverter-assisted stage classifications and selectively positioning perforations in select stages based on the diverter-assisted stage classifications thereon.

EFFECT: technical result is higher intensification of production from a well.
