Explore the Andes from the comfort of your desk with content from the Andean Basins Virtual Research Symposium organized by AAPG’s Latin America and Caribbean Region with support from the Argentine Association of Petroleum Geologists and Geophysicists, the Argentine Geological Society, the Colombian Association of Petroleum Geologists and Geophysicists, the Colombian Geological Society and the Geological Society of Peru.

The Andean Basins Symposium formed part of the AAPG’s Latin America and Caribbean Region’s 2020 Virtual Research Symposia Series highlighting the geology of some of the Latin America and Caribbean Region’s most prolific basins.

Targeted to researchers and professionals working both in industry and academia, each 2-day symposium featured technical sessions, keynote presentations, interactive Q&A sessions and panel discussions featuring experts in the field.
