Improved oil recovery techniques and their role in energy efficiency and reducing CO₂ footprint of oil production

Production of mature oil fields emits significant amount of CO₂ related to circulation and handling of large volumes of gas and water. This can be reduced either by (1) using a low-carbon energy source and/or (2) reducing the volumes of the non-hydrocarbon produced/injected fluids. This paper describes how improved oil recovery...

On the sustainability of CO₂ storage through CO₂ – Enhanced oil recovery

This work uses pilot examples of CO₂ enhanced oil recovery to analyze whether and under which circumstances it is exergetically favorable to sequester CO₂ through enhanced oil recovery. We find that the net storage efficiency (ratio between the stored and captured CO₂) of the carbon capture and storage (CCS)...
