Dr. Bjorn Wygrala is a petroleum geoscientist with more than 40 years of experience in the global E&P industry. He is an Australian national, graduated from Cologne University in Germany and started his professional career as a sedimentologist and basin analyst in minerals exploration in Australia. He then entered the field of petroleum geology with a start-up software company developing petroleum systems modeling technology, and he completed a doctorate thesis in petroleum geology supported by Eni/Agip in Italy. Dr. Wygrala has a wide breadth of knowledge on Basin and Petroleum Systems Analysis and Modeling, ranging from exploration for both conventional and unconventional hydrocarbons to special topics such as gas hydrate and pore pressure prediction, and basin to play to prospect scale geologic risk assessments. He has engaged with E&P companies in more than 50 countries during his career and his exposure and experience of how clients adopt and utilize BPSM have enabled him to provide advisory services and develop customized service programs. These include peer review and services for government agencies including yet-to-find resource assessments according to industry standard best practices, for example as project advisor for the National Hydrocarbon Resource Assessment Program for all 26 basins of India. His activities also include long-term development of educational relationships through Student Lecture Tours, workshops, and online courses for leading international organizations such as the AAPG, EAGE and SPE, covering topics such as basin and petroleum systems analysis and its role in petroleum E&P, and the global energy transition. Following his retirement from the industry in 2020, he has continued his activities as a geological advisor including lectures on the global energy transition and role of E&P companies in this transition. Recent interests include the application of petroleum E&P technologies, data, and experience for the development of deep geothermal resources for electricity generation, and two chapters for a new book on petroleum systems analysis.
