| Abstract: | Brine chemical data obtained from oil wells in Cretaceous oilfields in the Southeastern Basin of Mexico show a complex evolution, with the following main hydrochemical processes: (1) mixing of highly evaporated brines, past the point of halite precipitation with seawater; (2) water/rock interactions between brines and carbonated rocks (dolostones). |
