A new stimulation technique that promotes the creation of hydraulic fractures through perforations that may have been ineffectively stimulated is helping to improve productivity in unconventional reservoirs. Engineers perform at least two fracturing treatments in an interval; the treatments are separated by a fluid containing a degradable diverting agent. Subsequent fracturing treatments stimulate regions that were bypassed during earlier treatments, thereby enhancing production.
