“…The relevance of the mineral dissolution/precipitation processes and the displacement of the (clay) mineral fines on the petrophysical/geohydraulic behavior of sandstones are already known and discussed in several studies substantiated by laboratory experiments in the framework of CCS-technology (e.g., Pusch et al 2009;Fischer et al 2010;Gouze and Luquot 2011;Kummerow and Spangenberg 2011;Myrttinen et al 2012;Pudlo et al 2012;Sell et al 2013;Nowak et al 2014). Thereby different types of autoclave experiments like flow-through tests on core samples (Gouze and Luquot 2011;Sell et al 2013) and static batch experiments on sandstones (Fischer et al 2010;Pudlo et al 2012) at different p-/T-conditions and time durations were conducted.…”

The characterization of the quality and storage capacity of geological underground reservoirs is one of the most important and challenging tasks for the realization of carbon capture and storage (CCS) projects. One approach for such an evaluation is the upscaling of data sets achieved by laboratory CO 2 batch experiments to field scale. (Sub)-microscopic, petrophysical, tomographic, and chemical analytical methods were applied to reservoir sandstone samples from the Altmark gas field before and after static autoclave batch experiments at reservoir-specific conditions to study the relevance of injected CO 2 on reservoir quality. These investigations confirmed that the chemical dissolution of pore-filling mineral phases (carbonate, anhydrite), associated with an increased exposure of clay mineral surfaces and the physical detachment and mobilization of such clay fines (illite, chlorite) are most appropriate to modify the quality of storage sites. Thereby the complex interplay of both processes will affect the porosity and permeability in opposite ways-mineral dissolution will enhance the rock porosity (and permeability), but fine migration can deteriorate the permeability. These reactions are realized down to *lm scale and will affect the fluidrock reactivity of the reservoirs, their injectivity and recovery rates during CO 2 storage operations.

“…For gas and fluid sampling, downhole sampling methods such as the UTube system are recommended as they minimise gas loss from fluids during sampling. Positive displacement samplers (PDS) or other similar down-hole samplers are also suitable for sampling of pressurised fluids as long as in situ pressure conditions are preserved during sampling (Myrttinen et al, 2012b).…”

“…This method offers novel usage of stable carbon isotope measurements in CO 2 monitoring. To date such measurements were most commonly utilised to evaluate CO 2 distribution processes in the subsurface (Myrttinen et al, 2010(Myrttinen et al, , 2012bNowak et al, 2013). When the difference between δ 13 C values of DIC and CO 2 and hence 10 3 lnα 13 C DIC-CO 2 data are determined and interpreted, carbon isotope fractionation factors between all present DIC species and the gaseous CO 2 must be considered (Zhang et al, 1995).…”

“…Examples of such applications include investigations in carbon cycle and flux (e.g., [50][51][52][53]), chemical weathering (e.g., [54]), degassing from thermal and cold springs (e.g., [55,56]), volcanic-hydrothermal systems (e.g., [57,58]), and, as a relatively new field, geochemical trapping in CO 2 injection (carbon capture and storage (CCS)) projects (e.g., [59][60][61]). …”

“…Recently, this approach was applied to several studies related to the subsurface storage of CO 2 (CCS), e.g., geochemical trapping in CO 2 injection projects (e.g., [59,60]). Nisi et al [61] investigated the isotopic carbon of dissolved CO 2 and DIC related to surface and spring waters and dissolved gases in the area of Hontomín-Huermeces (Burgos, Spain) to verify whether CO 2 leakages, induced by the injection of CO 2 , might have been able to affect the quality of the waters in the local shallow hydrological circuits.…”

Water demand for urban, industrial, and agricultural purposes is a major concern in developed and third world countries. A careful evaluation for an appropriate and sustainable use of water resources is a priority. Geochemical processes can lead to measurable variations of the aquatic environment, which can be studied through the analysis of the dissolved solutes. Even if this review is not meant to be exhaustive, it is intended to give a view on the importance of environmental isotopes in the context of groundwater quality assessments. This is done by briefly recalling some basic notions for each described system, followed by relevant applications and reports about some significant case studies. This review includes well-established isotopic systematics, such as those of O and H in water, C in dissolved inorganic carbon (DIC), S and O in sulfates, and N and O in nitrates and those of boron and Sr, which in the last lustrums have found large application in the field of water geochemistry. This chapter ends with some examples related to nontraditional isotopes, i.e., Fe, Cr, and Cu, in order to highlight the potential of the environmental isotopes to trace sources, fate, and behavior of different solutes and metals in surface water and groundwater.
