Basin, sedimentary groundwater

Permeabilities in sedimentary basins are known to vary with the scale of observation (e.g. Bredehoeft et al., 1983,1992 Chapman et al, 1991 Neuzil, 1986). Different techniques are being developed to estimate reservoir- and basin-scale permeabilities, e.g. computer-aided techniques based on relations between characteristics of depositional systems and permeability distribution (Weber, 1982,1987 Stam, 1989 Stam et al., 1989 Mijnssen, 1991), and techniques based on numerical simulations of basin-scale groundwater flow in combination with known groundwater pressure distributions (e.g. Bredehoeft et al., 1983, 1992 Burrus et al., 1991), techniques that use numerical models of coupled groundwater flow/heat flow and known thermal characteristics to estimate basin-scale permeabilities (Chapman et al., 1991).

Fig. 2.4. Example of a sliding-fugacity path. Deep groundwaters of a geopressured zone in a sedimentary basin migrate upward to lower pressures. During migration, CO2 exsolves from the water so that its fugacity follows the variation in total pressure. The loss of CO2 causes carbonate cements to form.

In this chapter we review what is known about the geochemistry of water in sedimentary basins in the continental and transitional continental oceanic crust. The emphasis is on water below the zone of shallow meteoric groundwater circulation, and on the main processes that are responsible for the modiflcation of the chemical and isotopic composition of these waters including (i) mixing ...
