Lecturers:
Claudio Larriestra: Master’s degree in Geology from the National University of Córdoba (1976).
He has over forty years of experience in data analysis applied to exploration and production (E&P), with expertise in hydrocarbon exploration, reservoir geological characterization, and 3D modeling.
He has led projects for various oil companies in several countries, including Argentina, Colombia, Venezuela, Bolivia, Ecuador, Peru, and the United States. He currently works as a consulting geologist, specializing in reservoir modeling, geostatistics, and geological data science applied to E&P, through his company GEODATATECH SRL.
From 2014 to 2018, he worked as a researcher at the state-owned company YPF Tecnología S.A., developing new reservoir modeling methods with a particular focus on the integration of chemostratigraphy and seismic data, applied to both conventional and unconventional reservoirs.
Between August 2002 and 2014, he served as president of Larriestra Geotecnología S.A., a company he founded, specializing in statistical data analysis and geological modeling for E&P, as well as surface and well geochemistry projects.
From 1993 to 2002, he worked as an independent consulting geologist in reservoir exploration and evaluation through his own company Larriestra, Curia & Asociados.
Additionally, from 1991 to 1993, he was Head of Special Studies at the oil company CAPSA-CAPEX.
Between 1989 and 1991, he worked as a log analyst for Western Atlas Argentina.
From 1980 to 1988, he served as a research geologist at the National University of Rosario, participating in sedimentology projects.
In 1989, he was awarded the SAPIU (CONICET) project grant for the National University of Patagonia.
As an academic, he taught Geomorphology at the National University of Rosario (1978–1984) and served as Director of the Geology Department (1986–1988). He also taught Statistics and Geochemistry as an associate professor at the National University of Patagonia (1989–1990).
He is the author of over 40 scientific papers published internationally and has received several awards at national conferences. In 2010, he was recognized by the American Association of Petroleum Geologists for his research on Multipoint Simulation applied to Complex Geometry Reservoirs.
He is also a permanent member of the International Association for Mathematical Geosciences, among other professional organizations.
Fernando Larriestra: PhD in Natural Sciences from the National University of La Plata (2025). He has 18 years of experience in the oil and gas industry, with expertise in organic petrology, geochemistry, and chemostratigraphy for unconventional reservoirs; surface organic geochemistry applied to exploration and surface mapping for conventional reservoirs; and research in vascular plant paleobotany.
He has participated in projects for various oil companies in Argentina and Uruguay, including YPF, ANCAP, Pampa Energía, Petrobras, Pluspetrol, among others. He is also a professor of Paleontology II at the National University of La Plata and has been in charge of the microscopic inventory at the Museum of La Plata since 2023.
He currently works as a consultant in geoscience areas that include the integration of organic and inorganic well data analysis. He conducted research as a consultant for Geodatatech SRL (2023–2025).
Previously, he worked at YPF Tecnología S.A. (Y-TEC) as a technologist (2015–2023), focusing on organic petrology and palynology, organic geochemistry, chemostratigraphy, and surface geochemistry. From 2007 to 2012, he worked at Larriestra Geotecnología S.A., leading surface geochemistry survey research and working as a technician in chemostratigraphy analysis. He also worked as an independent consultant between 2013 and 2014.
He is the author of more than 30 unpublished technical reports on topics such as organic petrology, organic geochemistry, chemostratigraphy, environmental impacts of the oil industry, and surface geochemistry surveys. He has also authored 19 scientific articles and conference presentations since 2007.
