Integrated Modeling of Reservoir Fluid Properties and Multiphase Flow in Offshore Production Systems / Petroleum Engineering (PDF)

Tobias R. Gessner graduated in Mechanical Engineering (2006) from the Federal University of Santa Catarina (UFSC), with a master's degree (2010) and a doctorate (2021) from the same institution. He has been working at Petrobras as a flow assurance engineer since 2008, where he provides technical support in multiphase flow simulations for new offshore oil and gas projects, as well as for production monitoring in mature fields. His main interests are mechanistic models of gas-liquid flows, characterization of PVT samples, and compositional modeling of petroleum reservoir fluids.Jader Barbosa Jr. holds a degree in Mechanical Engineering (1995) from the Federal University of Rio de Janeiro (UFRJ), a Master's in Mechanical Engineering (1997) from COPPE/UFRJ, and a Ph.D. in Chemical Engineering from Imperial College London, UK (2001). He is a professor at the Department of Mechanical Engineering at UFSC, where he conducts research in engineering and thermal sciences. His areas of specialization include mixture thermodynamics and physical properties, phase change, multiphase flows, enhanced heat transfer, and not-in-kind cooling technologies.








Dr. Barbosa was awarded the Dudley Newitt Prize (2001) for his exceptional doctoral work by Imperial College. In 2004, he received the Young Scientist Award from the EUROTHERM Committee. During his time at UFSC, he has served as an advisor or co-advisor for 17 doctoral theses and 35 master's theses. Six of these theses have received the ABCM-Embraer and CAPES Thesis Awards.
