Abstract

In the face of escalating global climate change, Carbon Capture, Utilization, and Storage (CCUS) technologies have become indispensable for climate change mitigation. The application of carbon dioxide in geological fields, such as Enhanced Oil Recovery (CO2 – EOR) and geological sequestration, presents both promising prospects and significant challenges. There are potential risks of leakage during geological sequestration, which can threaten groundwater and soil environments. Moreover, the long – term impact of carbon dioxide injection on geological structures and their stability remains uncertain. Comprehensive well logging technology has emerged as a powerful tool to address these issues. By continuously monitoring key parameters like formation pressure, temperature, and gas composition in real – time and integrating modern data analysis methods, it can precisely evaluate the effects of carbon dioxide injection, predict and monitor its migration and distribution, and ultimately reduce leakage risks and ensure the safety and long – term stability of geological applications.
