We are currently modifying the way we present the Rock Geochemical data in the Brazil Geodatabase. Today, there are more than 100,000 analyzed rock samples from 544 selected wells, with around 130 wells covering the Santos and Campos basins. The total organic carbon, rock-eval pyrolysis and vitrinite reflectance methods allow us to obtain total organic carbon (TOC), potential yield (S2), hydrogen index (HI), free
