EPIC invites graduate students, researchers, and reservoir engineering professionals to the short course entitled “Ensemble based Decision Making in Reservoir Management and Field Development Planning“, to be taught by Prof. Remus Gabriel Hanea, leading advisor on Reservoir Technology at Equinor (Norway), and Prof. Bogdan Sebacher, associated professor at the Military Technical Academy  of Bucharest (Romania).

The course will be offered in English, between June 27th and 29th, 2022, at the School of Mechanical Engineering (FEM) of the University of Campinas (UNICAMP), in Campinas, Brazil.

Prof. Remus Gabriel Hanea is the leading advisor on Reservoir Technology, Assisted History Matching and Optimization/Decision Making in the Subsurface Discipline Excellence department in Equinor. His background is in Applied Mathematics, and he has 15 years of experience in Uncertainty Quantification, Data Assimilation and Optimization, and Decision Making with applications in Atmospheric sciences, Hydrology and in various Energy domains (mainly O&G). He also has a part time professorship position at theUniversity of Stavanger (Norway), in the Department of Petroleum Engineering, in the group of Petroleum Geoscience Engineering. Remus’s main research topics are: Assisted History Matching and Robust Optimization for Reservoir Management, Value of Information, Decision and Risk Analysis and Geostatistics. Remus teaches a specialized course for PhD and MSc students on Inverse Modeling, Data Assimilation and Optimization with applications in Reservoir Management, and supervises MSc and PhD students.

Prof. Bogdan Sebacher is Associate Professor at the Military Technical Academy of Bucharest (Romania).
