Figure 2. Stratigraphic chart, with depositional environments and tectonic evolution of the sedimentary fill in the Neuquén Basin, highlighting main reservoirs and source rock intervals: lacustrine black shales (Kauffman) and marine organic-rich shales (Los Molles, Vaca Muerta and Agrio formations). A generalized timing of hydrocarbon generation is shown, along with the stages with strongest rate of kerogen-to-hydrocarbon transformation.
