Integrated Geochemical Methodologies Conducted in Pre-evaluation Procedures of Hydrocarbon Lead Zones

Geochemical procedures offer valuable insights about contouring the spatial distribution of a lead zone and prioritizing further depth investigations suitable to be applied. Data interpretation of Rock-Eval and preliminary X-Ray Diffraction results was done for dysodile shale samples collected from Oligocene outcrops of Getic Depression interest area. All samples have high potential for generating hydrocarbons according TOC values above 1%. HI, S2/S3 and kerogen type determinations indicate the rock formation is prone to generate oil and gas. Low Tmax values cannot be considered as accurate given the fact that the samples were collected from outcrops subject to environmental surface conditions.
