Abstract
The objective of this chapter is to provide an overview and discussion of the relevancy of various physical and chemical processes to be associated with the geological storage of CO2 at a particular site, and thereby serve as a bridge between the detailed process descriptions and modeling techniques to be presented in the following chapters and the studying and simulation of site-specific physicochemical behavior of a potential CO2 geosequestration site. The approach adopted is to address the relevancy of a given process in terms of the specific objectives, the technical issues of concern, or the key questions associated with CO2 geological storage, in the context of the geological settings and characteristics of the storage site. The suggested approach is exemplified by application to two field cases.
