Conclusion

The IEAGHG Weyburn-Midale CO2 Monitoring and Storage Project cannot answer all the questions that people may have about carbon capture and storage; as an adjunct to a CO2-EOR (enhanced oil recovery operation) it offers insights primarily into the measurement and monitoring of injected CO2. Having taken place in the geological formation with the largest single amount of injected manmade CO2 in the world, and as a research project with extensive peer-reviewed results, the project can offer evidence of safe and secure geological storage of CO2 and provide real data and scientific information for many of the public's most frequently raised concerns about CO2 storage.

The questions and answers covered in this publication offer key information that will help readers understand the science, logistics, benefits and potential risks of CO2 storage. Some readers may be new to the topic of CO2 geological storage, while others may have had similar projects proposed near where they live and therefore be familiar with some of the issues. While some of the questions and answers contained here also touch upon aspects of the carbon capture and storage chain (deep saline formation storage, transport, capture technologies), other active projects offer more detailed information on these additional topics. Readers are encouraged to investigate websites for more information (http://www.globalccsinstitute.com and http://www.sequestration.org).

Carbon capture and storage, if it is to go forward globally in a significant way to help alleviate the potential impacts of climate change, requires a significant level of understanding and dialogue on the parts of industry representatives, government oficials, policy makers, politicians and, most importantly, the general public. The Global CCS Institute and the Petroleum Technology Research Centire hope that this publication contributes to that dialogue and provides answers that will allow for CO2 storage to succeed on its scientific and environmental merits.
