Carbon Dioxide Sequestration in Geological Media—State of the Science
Over the past 20 years, the concept of storing or permanently storing carbon dioxide in geological media has gained increasing attention as part of the important technology option of carbon capture and storage within a portfolio of options aimed at reducing anthropogenic emissions of greenhouse gases to the earth’s atmosphere.
Research programs focusing on the establishment of field demonstration projects are being implemented worldwide to investigate the safety, feasibility, and permanence of carbon dioxide geological sequestration.
AAPG Studies 59 presents a compilation of state of the science contributions from the international research community on the topic of carbon dioxide sequestration in geological media, also called geosequestration. This book is structured into eight parts, and, among other topics, provides an overview of the current status and challenges of the science, regional assessment studies of carbon dioxide geological sequestration potential, and a discussion of the economics and regulatory aspects of carbon dioxide sequestration.

Geological sequestration of CO2 in brine-saturated formations has been proposed as a possible method to reduce emissions of this greenhouse gas to the atmosphere. To optimize the effectiveness of this method, the largest possible volume of CO2 should be sequestered over geological time. Sequestration over geological time can be thought of as permanent for the purposes of relieving climate-changing increases in atmospheric CO2 concentration. The least risky way to achieve permanent sequestration is to store the CO2 as a residual phase within a brine aquifer. Geological conditions that impact the volume of CO2 stored...
