"Seismic inversion and quantitative interpretation: the Brazilian experience"
Paulo Johann is currently the Senior Petrobras Advisor, based in Rio de Janeiro. Paulo has more than 40 years of technical and managerial experience in the petroleum industry. He graduated with a degree in geology from UNISINOS University, RioGrande do Sul, Brazil and received his D.E.A. and Ph.D. degrees in reservoir geophysics from Paris VI University, France. His career has encompassed activities in geophysical acquisition, geophysical interpretation, and reservoir geophysics. Paulo is also a frequent lecturer at Brazilian universities. He became active in the BrazilianGeophysical Society (SBGf) where he has served in many positions including its vice-presidency. He has published and presented several technical papers at SEG, EAGE,SPE, OTC, and SBGf. Paulo was appointed the first Central & South America HonorarySEG Distinguished Lecturer. He also served SEG as Vice-President. He is an active member of EAGE, SEG, OTC and SPE.

"Estimating elastic and reservoir properties by Bayesian seismic inversion"
Heidi Kjønsberg is a Senior Research Scientist at the Norwegian Computing Center, where she has worked for fourteen years on statistical modeling of geology in petroleum reservoirs. During the last seven years her main interest has been in Bayesian seismic inversion. She is currently the manager of the research and development consortium Geophysical Inversion to Geology (GIG), hosted by the Norwegian Computing Center. The consortium’s goal is to develop algorithms to analyse seismic data and calculate the probability for detecting subsurface sedimentary rocks and their properties. Heidi holds a PhD in theoretical physics from the University of Oslo.
Dario Grana
University of Wyoming
Wednesday 16 October 2024. 09:00 - 09:30
“Probabilistic approaches for seismic reservoir characterization: computational efficiency, uncertainty quantification, and anisotropy challenges”
Dario Grana is a professor in the Department of Geology and Geophysics at the University of Wyoming, where he holds the Wyoming Excellence Chair and is the Director of the Bayesian Learning Consortium. He received a Ph.D. in Geophysics at Stanford University in 2013 and a MS in Mathematics at University of Pavia, Italy, in 2005. He worked four years at Eni Exploration and Production in Milan. He joined the University of Wyoming in 2013. He coauthored the books “Seismic Reservoir Modeling” in 2021, and “Seismic Reflections of Rock Properties” in 2014. He is the recipient of the 2022 SEG Outstanding Educator Award, the 2017 EAGE Van Weelden Award, the 2016 SEG Karcher Award, and the 2014 Eni award with Gary Mavko, Tapan Mukerji, and Jack Dvorkin for “pioneering innovations in theoretical and practical rock physics for seismic reservoir characterization”. His main research interests are rock physics, seismic reservoir characterization, geostatistics, data-assimilation, and geophysical inverse problems.
