Abstract :
Fluid flow from reservoir to downhole could not be happened without perforation operation. Explosive shaped charge perforating method has been used as conventional perforation method by penetrating casing and formation. It has been utilized as an antitank device in World War II, and their use in perforation process have been commenced since set the standard in the industry. This method is focused and intensified into a small diameter jet that penetrates the casing and cement into the reservoir rock. The drawback of this method is formation damage that results in reducing permeability and expensive post-perforation operation. Also, plugging pore throat size will be occurred due to fine grain particles producing. High power lasers perforation method as a cutting-edge technology is being considered as a suitable alternative for conventional perforation method. In this paper, application of using laser perforation method and its’ effects on reducing formation damage which is lead to boost production rates, increase rock permeability and fracture formation will be presented.
