Biography: Dr. Bernhard KROOSS is a Senior Research Scientist and lecturer and head of the Petrophysical Laboratory at the Institute of Geology and Geochemistry of Petroleum and Coal, Energy and Mineral Resources (EMR) Group, RWTH Aachen University, Germany,
Dr. KROOSS holds a Diploma (M.Sc. equivalent) in Chemistry (Macromolecular Chemistry and Physical Chemistry) of RWTH Aachen University.
During his PhD project at the Institute of Petroleum and Organic Geochemistry of the Jülich Research Centre (FZ-Jülich), Germany, he conducted experimental studies on “Diffusive transport of light hydrocarbons in sedimentary rocks” and earned a PhD degree of RWTH Aachen University in 1985.
From 1984 to 1999 - with a one-year interim post-doctoral fellowship period at the University of Oklahoma, Norman, Oklahoma, USA, in 1986/87 – Dr. KROOSS was a Research Scientist at the Institute of Petroleum and Organic Geochemistry of the Jülich Research Centre. His main research during this period was on generation and migration processes of petroleum and natural gas. He participated in several international studies on caprock integrity and fluid transport processes in low-permeable pelitic rocks. Another focus was on the reaction mechanisms (kinetics) of natural (hydrocarbon) gas generation and the origin of non-hydrocarbon gases, in particular molecular nitrogen (N2), in sedimentary basins.
In 1999 Bernhard KROOSS joined the Institute of Geology and Geochemistry of Petroleum and Coal of RWTH Aachen University, Germany. Here he set up a petrophysical laboratory for fluid transport experiments related to single- and multi-phase fluid flow in low-permeable rocks and high-pressure gas sorption experiments. These latter experiments were performed in the context of projects on coalbed methane (CBM) and geological storage of carbon dioxide (CO2). His current research interests comprise experimental investigation of transport processes in sedimentary rocks, natural gas generation and migration, natural gas isotope geochemistry, physical chemistry of geological systems.
Dr. Alexandra AMANN-HILDENBRAND is a Senior Research Scientist at the Institute of Geology and Geochemistry of Petroleum and Coal, Energy and Mineral Resources (EMR) Group, RWTH Aachen University, Germany.
Dr. AMANN-HILDENBRAND holds a Diploma (M.Sc. equivalent) in Geoscience of RWTH Aachen University.
During her PhD project at the Institute of Geology and Geochemistry of Petroleum and Coal in Aachen she conducted experimental studies on “Fluid Transport Processes in Mudstones” and earned a PhD degree of RWTH Aachen University in 2003.
From 2003 to 2008 Dr. AMANN-HILDENBRAND was employed as a researcher at VITO (Vlaamse Instelling voor Technologisch Onderzoek) in Belgium. She was involved in different projects regarding the CO2 sequestration potential and risks in Belgium, the quantification of the in-situ methane content of the coal-bearing sequences in NE-Belgium and the analysis of geothermal use of the flooded coal mines in Heerlen (the Netherlands).
In 2008 Alexandra AMANN-HILDENBRAND again joined the Institute of Geology and Geochemistry of Petroleum and Coal of RWTH Aachen University, Germany. In the petrophysical laboratory she is conducting experiments with focus on fluid transport processes in fine-grained, low permeable rocks. Data are analysed with respect to their dependence on fluid/confining pressure, water saturation, and gas type. This enables the extrapolation of the experimental observations to the natural geological system. |
