Hydraulic fracturing is guaranteed to create or enlarge fracture, so the hydraulically created fracture acts as a conduit in the rock, allowing the groundwater to flow more freely through the fracture system. In a recent study, it showed that 12 wells where hydraulic fracturing was performed increased well production. However, it was estimated not to present representation by rock type due to not enough wells. Therefore, this study was performed to clarify the application of hydraulic fracturing at 19 water wells. Rocks were divided into igneous rocks (9 sites), metamorphic rocks (4 sites), and sedimentary rocks (6 sites) to evaluate representative features. As a result, the average of well yield increases $93.4\%$ in the igneous rocks, $103\%$ in the metamorphic rocks, and $42.2\%$ in the sedimentary rocks. Accordingly, hydraulic fracturing presented in this study provides an effective method for increasing well production
