Evaluation and monitoring of offshore CO2 storage using marine electromagnetic sounding

Year: 2024

Type: conference-paper

Abstract: The storage of offshore carbon dioxide (CO2) is seen as an effective way to reduce greenhouse gas emissions. Submarine sediments offer a large volume and adequate permeability for the long-term injection of CO2 at high pressure and low temperature. The selection and monitoring of offshore CO2 storage sites have a significant impact on their stability and safety. Therefore, accurately identifying the distribution of offshore CO2 storage is crucial for monitoring. This study utilizes marine controllable source electromagnetic sounding (CSEM) to investigate the sensitivity of identifying plume transport distributions in offshore CO2 storage monitoring. The results show that CSEM is effective in monitoring the distribution of CO2 plumes during offshore storage processes. The changes in electromagnetic field response can reflect the distribution of CO2 plumes, providing important basis for the stability and safety of offshore CO2 storage site selection and monitoring.
