To study stimulation and diversion efficiency, WellWatcher Stim service used alongside microseismic analysis and step-down tests to monitor downhole and reservoir events.

Microseismic analysis, shown for one interval of three diversion stages, indicated widely scattered events, making it difficult to identify fluid entry points. Step-down testing indicated only how many perforations were taking fluid. WellWatcher Stim service indicated the approximate depth of the most profound fractures in each stage, clearly showing the diversion of fluid from one cluster to another.
