Explore Offshore Colombia, Ecuador, Peru and Chile from the comfort of your desk with content from the Pacific Basins Virtual Research Symposium organized by AAPG’s Latin America and Caribbean Region in partnership with the Colombian Association of Petroleum Geologists and Geophysicists, the Colombian Geological Society and the Geological Society of Peru.

The Pacific 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.


All times are listed in COT/PET/ECT/CDT (GMT -5)

Presentations will be delivered in English unless otherwise noted. Presentation slides will be shown in English.

All symposium materials, including abstracts and presenter bios, will be provided in English.
