Evolution of temperatures at the site of well RJS-99 during the evolutionary history of the Campos basin. The dotted lines in red color indicate the isotherms. The numbers beside the isotherms indicate values of temperatures in degree centigrade. The dashed curves indicate TTI indices of 15 and 60, corresponding, respectively, to onset and peak of oil generation. The continuous lines indicate time-depth sequences in the subsidence history of the main sedimentary formations.
