Hydraulic fracturing has been widely applied in low-permeability reservoirs to enhance hydrocarbon productivity by creating high-conductivity flow paths and reducing near-wellbore skin. In this study, an integrated approach is proposed by embedding detailed hydraulic fracturing design parameters into a reservoir simulation model to improve the accuracy of post-fracturing production. The AMB-2X exploration vertical well, located in the South Natuna Sea, was selected as a case study due to its multilayer tight gas characteristics and the availability of comprehensive fracturing design data. The main target of the well is the LG Formation. Initially, hydraulic fracturing design for nine stages was performed and optimized based on log-derived stress profiles, offset well analogs, and reservoir quality indicators. Conventionally, post-fracturing production analysis relies on skin factor estimation through DST results and transmissibility-rate correlation. However, this study advances the analysis by incorporating fracture geometry parameters—such as half-length, width, height, and SRV expansion value— into the dynamic simulation model. As a result, the integrated model produces the same results as the conventional method after stimulation. The approach demonstrates how coupling fracture design with reservoir simulation can reduce uncertainty in production estimation and support development planning in tight gas fields.
