Core Viewpoint - The commencement of drilling for China's first offshore carbon capture, utilization, and storage (CCUS) well marks a significant advancement in the country's efforts to enhance oil recovery while reducing carbon emissions [1][3]. Group 1: Project Details - The CCUS well is being drilled at the Enping 15-1 platform, which is the largest offshore oil production platform in Asia, located approximately 200 kilometers southwest of Shenzhen in a water depth of about 90 meters [3][4]. - The Enping 15-1 oil field has a high carbon dioxide content, and conventional extraction methods would lead to increased CO2 emissions and corrosion of offshore facilities. The CCUS project aims to mitigate these issues while promoting sustainable development [3][4]. - The CCUS well is designed to reach a depth of 3,243 meters and employs an innovative "old well new use + layered gas injection" approach. The project is expected to begin trial injection operations in April 2023 [4]. Group 2: Expected Outcomes - The CCUS project is projected to inject over 1 million tons of CO2 into the seabed over the next decade, while also enhancing oil recovery rates and driving an increase in crude oil production by 200,000 tons [4]. - As of June 2023, the first offshore carbon capture and storage (CCS) demonstration project in China has operated safely for nearly 13,000 hours, successfully sequestering over 180,000 tons of CO2 [3][4].
