The first text on geological storage of CO2, using mathematical analysis to derive practical models

Carbon emissions in the form of carbon dioxide (CO2) present a host of challenges that directly impact social, economic, and environmental sectors. Geological storage of captured CO2, as part of a Carbon Capture and Storage (CCS) strategy, can help reduce carbon emissions. Geological carbon storage involves injection of captured CO2 into appropriate geological formations deep underground, where the CO2 should remain for hundreds to thousands of years or more. In Geological Storage of CO2, the basic principles that underlie geological storage are presented, including fundamentals of fluid movement in the subsurface, and the mathematical models used to describe storage operations. The book includes:

• A self-contained exposition ranging from fundamental concepts of flow in porous media to models that can be applied to real-world problems

• Practical modeling techniques for geological storage

• Example applications to real-data sets

• A general modeling framework that allows a range of processes to be incorporated in a consistent way

By building and expanding on the essentials of carbon storage modeling, Geological Storage of CO2 provides a strong foundation from which researchers, storage operators, and regulators can perform analyses needed for their own decision making.

Despite the large research effort in both public and commercial companies, no textbook has yet been written on this subject. This book aims to provide an overview to the topic of Carbon Capture and Storage (CSS), while at the same time focusing on the dominant processes and the mathematical and numerical methods that need to be employed in order to analyze the relevant systems. The book clearly states the carbon problem and the role of CCS and carbon storage. Thereafter, it provides an introduction to single phase and multi-phase flow in porous media, including some of the most common mathematical analysis and an overview of numerical methods for the equations. A considerable part of the book discusses the appropriate scales of modeling, and how to formulate consistent governing equations at these scales. The book also illustrates real world data sets and how the ideas in the book can be exploited through combinations of analytical and numerical approaches.
