|6 Reservoir Description and Dynamics
Different geological storage locations have been considered in literature
such as basalt rocks (McGrail et al., 2006), salt caverns (Dusseault et al.,
2001) and former coal mines (Shi & Durucan, 2005, Wo & Liang, 2005).
The main focus of past and current research, however, has been on oil and gas
fields – either depleted or in the context of enhanced oil recovery (EOR) – and
deep saline formations or aquifers (Holloway et al., 2005) which this paper
will focus on.
Numerical modeling of CO2 storage has been performed since the early 1990’s (Holloway, 1996, van der Meer, 1995, Holt et al., 1995, Law & Bachu, 1996, van der Meer, 1992, van der Meer, 1993, van der Meer, 1996) and, although computationally expensive, can capture phenomena not considered in analytical solutions. More recently, researchers have studied near basin-scale systems and long time frames, applicable to large storage sites (Kumar et al., 2005, Mo & Akervoll, 2005, Ozah et al., 2005, Akaku, 2008). Research on the basis of these numerical models has been extended to study the large-scale impact CO2 injection has on groundwater systems and up-dip or overlying fresh water aquifers, suggesting that especially the pressure distribution and displacement of brine could have an impact on a much larger scale than the CO2 plume itself (Nicot, 2008, Birkholzer et al., 2009, Birkholzer & Zhou, 2009).
