Modern perforating technology has evolved from simple holes in the casing to scientific, objective-oriented services adapted to achieve sophisticated and versatile completion designs. Perforating is now used to optimize permanent completions, temporary completions such as DSTs, and workovers. Along with services such as hydraulic fracturing, sand management, extended-reach and horizontal wells, completion fluids engineering, and well testing, perforating has become indispensable for improving productivity. Different type of perforation system are performing such as including but not limited to HSD,Enerjet and punching services with Wireline and TCP methods. Also, perforation system could be designed in advance and interpreted the result with special software by WSI reservoir champion engineers.
