Carbon dioxide sequestration is a technology that is being explored to curb the anthropogenic emission of CO2 into the atmosphere. Carbon dioxide has been implicated in the global climate change and reducing them is a potential solution. The injection of carbon dioxide for enhanced oil recovery (EOR) has the duel benefit of sequestering the CO2 and extending the life of some older fields. Sequestering CO2 and EOR have many shared elements that make them comparable. This volume presents some of the latest information on these processes covering physical properties, operations, design, reservoir engineering, and geochemistry for AGI and the related technologies.
