【 摘 要 】

Wells that experience decrease in its production can be optimized by wells stimulation in order to increase its productivity. Stimulation have two types, they are reservoir stimulation and wells stimulation. Stimulation methods could be done with mechanical and/or chemical processes. Reservoir stimulation is divided into 3 methods. There are hydraulic stimulation, thermal stimulation, and chemical stimulation. This paper would be focusing the study in hydraulic fracturing method. Hydraulic fracturing method includes injecting fluids that could make fractures in the formation. Injection fluids contains proppant that could maintain the fractures after the fluid is injected to the formation. The purpose of this study is to analyze hydraulic fracturing stimulation method that could be done in geothermal wells to improve wells productivity.
