With the continuous increase in global greenhouse gas emissions, impacts of climate change are becoming increasingly severe. In this context, geothermal energy has gained significant attention due to its numerous advantages. Alongside advancements CO2 geological sequestration technology, use as a working fluid systems emerged key research focus. Compared traditional water-based fluids, possesses lower viscosity and higher thermal expansivity, enhancing mobility reservoirs enabling more efficient heat transfer. Using not only improves extraction efficiency but also facilitates long-term within reservoirs. This paper reviews recent progress on Enhanced Geothermal Systems (EGS), with focus potential advantages improving exchange power generation capacity. Additionally, study evaluates mineralization effects reservoirs, well impact reservoir properties. Finally, discusses technological developments economic analyses integrating other technologies. By systematically reviewing EGS, provides theoretical foundation for future development using fluid.

Establishing a potential site characterization for carbon dioxide (CO2) storage in geological formations anticipates the appropriate reservoir properties, such as porosity, permeability, and so forth. Well logs seismic data were utilized to determine key including volume of shale, water saturation. These properties cross validated with core sets ensure accuracy. To enhance permeability estimation, sophisticated machine learning (ML) methods employed, categorizing into five classes ranging from extremely good (0) very low (4). Two ML models, Naïve Bayes (NB) multilayer perceptron (MLP), applied predict permeability. The MLP model outperformed NB model, achieving 99% training accuracy 93% testing accuracy, compared 78 73%, respectively, model. resulting comprehensive revealed distribution across three stratigraphic layers: B100 zone exhibited suitable caprock, while D35-1 D35-2 zones demonstrated excellent indicating CO2 reservoirs. "X" field reservoir, located at depths exceeding 1300 m, meets depth requirements (1000–1500 m) storage. Our integrated approach, combining empirical ML-based calculations well logs, proved effective characterizing reservoir. lithological defined nonreservoir sections between clay silt lines, identifying important caprocks interbedded shale/clay intervals. Seismic profiling confirmed continuous caprock overlying D group zone, crucial preventing upward migration. This analysis supports Malay Basin viable storage, contributing ongoing efforts capture research.
