Abstract

Summary

Punta del Este basin, located offshore Uruguay, shares similarities in its geology and hydrocarbon potential with offshore Namibia Orange basin. One of the crucial components of identifying suitable areas for hydrocarbon exploration in both regions is the presence and characterization of source rocks. Recent oil discoveries in offshore Namibia, such as the Venus, Graff, La Rona and Jonker are in areas with similar geological characteristics to this basin.

Source rocks with hydrocarbons occupying pore space are expected to be highly resistive. If they can be imaged with CSEM (Controlled Source Electro Magnetic) data, together with seismic attributes such as sweetness and others, a CSEM inversion could provide a supplementary tool to identify source rocks. Latest CSEM inversion highlights a potential shallower source rock, interpreted to be of Turonian age. This study aimed to co-render seismic and resistivity response at this level to investigate relationships which could indicate source rock potential. The Turonian, along with the Aptian source rock, is responsible for 29% of the petroleum accumulations in the world. In the South Atlantic the Turonian source rock was proved in several wells in Pelotas and Santos as well as in Namibia and Walvis basins.
