We present a high-level assessment of the potential for CO geological storage of two Argentiniansedimentary basins, the Neuquén and Golfo San Jorge basins.Applying a few elimination criteria, suitable areas for CO22 storage were identified in several geologicalunits in both basins. The analysis was then restricted to the areas of oil and gas fields in each unit,yielding approximately 200 prospects per basin. We selected a series of criteria to evaluate eachprospect, such as the petrophysical parameters and estimated CO storage capacity of the reservoirand the characteristics of the containment system. We used exploratory level data gathered mostlyfrom published works. Finally, we assigned a relative weight to each criterium and applied a multi-criteria decision method to rank the prospects. 2Our results show that, at the current level of analysis, the Centenario Formation in the Neuquén Basinand the Cañadón Seco Formation (and equivalents) in the Golfo San Jorge Basin, display the mostpromising characteristics. We expect the results of this work can serve as the starting point for amore comprehensive and detailed assessment of their potential as geological sinks of CO2.
