This publication assesses the potential of carbon dioxide-enhanced oil recovery (CO2-EOR) technology to mitigate climate change in Indonesia. Although the technology was designed to rejuvenate oil production in mature oilfields, its value in permanently storing CO2 has recently attracted global interest. The publication concludes that CO2-EOR could provide a win-win for Indonesia by improving oil production while also helping to reduce the country’s rapidly rising greenhouse gas emissions. It proposes a pilot project as a critical first step to deploy the technology and provides insights on how to create a supportive regulatory environment and financial incentives.
