The Progress of Offshore CO2Capture and Storage

Abstract

With the development of the offshore oil and gas fields, more and more offshore oil and gas fields are found to have high carbon dioxide. In addition, as peaking carbon dioxide emissions and carbon neutrality were written into the government work report for the first time, the correct separation and emission of CO2 have become a key issue that needs to be solved by offshore oil and gas fields. In this paper, we studied two CO2 separation methods suitable for offshore platforms and the current status of CO2 offshore storage and application. Moreover, the development of offshore carbon dioxide storage application was investigated in detail, and the technical characteristics and application prospects of CO2-EOR and CO2 replacing combustible ice were analysed and discussed. This paper analyses the challenges and countermeasures of offshore CO2 storage from many aspects. It provides a theoretical reference for future CO2 treatment in offshore oil and gas fields.
