Basin Pannonian

The area under study comprises the western part of the Padurea Craiului Mountains in conjunction with the north eastern extremity of the Pannonian Basin (Oradea - Felix zone). The Padurea Craiului Massif had a long-lasting evolution with a pre-Hercynian start, being...

Noble gases exist in formation waters as uncharged, nonpolar species. They preferentially partition from aqueous solutions into nonpolar solvents such as crude oil and natural gas (Kharaka and Specht, 1988). The degree of partitioning depends on such factors as temperature, gas atomic radius, and the salinity of the aqueous phase. Distinct variations in Ne/ Ar, Kr/ Ar, and °Xe/ Ar are produced by fractionation in multiphase fluid systems. These variations have been used as a tool in oil exploration and reservoir evaluation. Pinti and Marty (2000) give detailed examples of these applications in the Pannonian Basin, Hungary and in the Paris Basin, France. 

At temperatures above c,100°C steroidal aromatization occurs at an increasingly faster rate than sterane isomerization. As a result, in young extensional basins in which there is a high heat flow, such as the Pannonian Basin in Hungary, aromatization can be virtually complete while sterane isomerization is at an early stage (Fig. 5.53a). In older basins with more moderate heat flows, such as the East Shetland Basin (northern North Sea Fig. 5.53b), the steroid isomerization and...

Figure 15. CH Ar plotted as a function of depth for gas fields in the Vienna basin, Austria (Ballentine 1991), Pannonian basin, Hungary (Ballentine et al. 1991) and the Po Basin, Italy (Elliot et al. 1993). These vdues are compared with the saturation GHV Ar value calculated for seawater containing 7.5xlO cm (STP) Ar, a salinity of 0.23M NaCl equivalent, a temperature gradient of 0.03 K/km and at hydrostatic pressure (Solid line). The dashed line is the saturation value if the salinity increases to 3 M NaCl equivalent. The gases in the Pannonian and Po basin studies lie on the saturation line for their depth, are closely linked to the groundwater system, and may have exsolved from solution. These contrast with the Vieima basin gases that have had far less contact with the groundwater system.
