Geochemical and Chemostratigraphic Assessment of the Albian-Oligocene Interval of the Northern Portion of Santos Basin

Abstract

The geochemical study of rocks, in the oil industry, is an efficient tool utilized for characterizing the organic content of rocks and possible source rocks. The data analysis of total organic carbon, insoluble residue, and pyrolysis analyses, in six wells, resulted in the identification of four chemostratigraphic units, besides two potential source rocks in the post-salt interval of the northern portion of the Santos Basin.
