Carbon Accounting for Carbon Dioxide Enhanced Oil recovery

Abstract

It is recognised from currently operating CO2EOR projects that the operations and processes involved in CO2EOR are energy intensive and may compromise the overall carbon footprint of a project (ARI, 2009; Dilmore, 2010). This study intends to provide a medium to high level life cycle assessment of CO2EOR operations for a theoretical offshore North Sea project. The study will focus on upstream operations involved in the CO2 EOR process and aims to quantify all significant processes and activities that contribute to a projects carbon footprint. An attempt will also be made to incorporate the impact of new infrastructure on the carbon inventory of the project.
