description A sudden drop of production rate can happened due to formation damage, mechanical failure and others unprecedented problems. Selecting the suitable well stimulation method to treat the unproductive reservoir or to restore the reservoir productivity for a dual-string completion well which have multiple production zones becomes a challenge as there is no direct access to the problem production zone to investigate the root cause of the problem. Conventional method such as acidizing and hydraulic fracturing not an option for this situation, therefore re-perforation the production zone method have been decided to restore back the reservoir productivity. The case study have showed that a deep penetrating charge perforating system is required for this perforation method as the perforation need to penetrate the blast joint, annulus material, casing, the formation damaged zone and the formation.
