Tectonic Evolution and Source Rock Assessment of Offshore Argentina

This evaluation of the Argentine margin fully investigates the structural and tectonic evolution of the region from early basin rifting to the complete rifting of the South Atlantic. It also evaluates the impact this had on source rock deposition, preservation and maturity within the offshore basins.

Getech’s unique gravity and magnetic databases were used to generate a structural framework and crustal architecture interpretation, which was then integrated with Getech’s Global Plate Model. The tectonostratigraphic evolution of the margin provides answers to the key issues of source, reservoir and seal distribution. The 1D basin modelling of the source rocks within the basins provides insight into source rock maturity.

Evaluating the timing and geometry of basin development and examining how these have impacted the developing petroleum system play elements are key to achieving exploration success in this frontier region.
