This study explores the optimization of horizontal multistage hydraulic fractured well placement in a basement reservoir using the Differential Evolution (DE) algorithm, with a case study in Field R. The complex geological and operational characteristics of basement reservoirs pose significant challenges, particularly in data acquisition. This research aims to develop an approach for basement reservoir development without relying on 3D geomechanics data. The optimization process involves the use of tNavigator software for simulating and determining the optimal well placement and hydraulic fracturing design parameters. The results indicate that the optimum well placement and fracture design significantly enhance gas production, with a cumulative gas production of 23.02 BSCF and a maximum production rate of 19 MMSCFD. Sensitivity analysis highlights that the number of fracturing stages is the most critical parameter affecting total gas production. This study provides a workflow that can be utilized for similar optimization objectives in other 3D models, offering a faster and more efficient optimization process. This study’s findings contribute to improved reservoir management practices in oil and gas industry, particularly for unconventional reserves
