Our studies will include geochemical analyses of drill core samples to decipher changes in the catchment and in the lake itself during the last 200,000 years. We propose to do numerous biomarker and stable isotope investigations on selected core regions, focussing on glacial-interglacial transitions and on millennial-scale hydroclimate variability (Dansgaard Oeschger events). This project is embedded in the Paleovan Research Program including scientists from Switzerland, Germany, and Turkey.
This project is funded by the FWF (P29310) and is conducted in cooperation with the Chair of Physical Metallurgy and Metallic Materials, the Erich Schmid Institute of Materials Science and RWTH Aachen.
Recently, great progress was achieved in the development of high resolution imaging techniques, also leading to their increased application in geosciences. Many open questions are related to the chemical composition and structure of organic matter (OM) in fine-grained sediments (shales) and coals, as well as their transformation under thermal stress (“thermal maturation”). It is suggested that processes in the nanoscale largely influence (1) gas storage in pores generated during thermal maturation and (2) incorporation of inorganic elements in OM (“kerogen”) as well as minerals formed within the kerogen. However, it is unclear how the different kerogen types behave.
As a result of a long-lasting and complex geological history, organic-matter-rich black shales are found at different stratigraphic levels throughout Western Ukraine. The shale gas potential of Silurian facies, as well as the petroleum source rock potential of Oligocene, Miocene and Lower Cretaceous black shales will be analyzed and discussed in detail. In addition, oil samples from various wells across Western Ukraine will be sampled and correlated with existing data.

Sedimentary basins are finite spatial resources, which face increasing competition between different areas of utilization, including groundwater, mineral water, geothermal energy, oil and gas, as well as underground storage. Hence, the knowledge of the deep subsurface is an important aspect for the security of supply, economic development and sustainable management of the underground. Within this context, it is crucial to recognize, define and delimit hydrostratigraphic units, which may occur in one or more lithostratigraphic units.
During the Oliogo-/ Miocene (approximately 34-17 Mio years ago) organic rich sediments were deposited in an epicontinental sea, the so called Paratethys. These sediments belong to one of the most important oil source rocks of Central and Eastern Europe. This Dissertation aims to comply a high resolution description of the geology and geochemistry of three cross sections along the eastern, southern and western shore of the Paratethys Ocean in today’s Georgia, Turkey and Romania.
The discovery of oil and gas, some 150 years ago, has triggered an intensive and extensive hydrocarbon exploration in the Vienna Basin. The oil and gas industry over the years has acquired a quit good understanding of the structure and evolution of the Basin, as well as detecting numerous HC accumulations in nearly all stratigraphic units within the basin but until now no study has ever focused on all parts of the HC-system in high resolution.

For the better understanding of gas generation and alteration in the Alpine Foreland Basin, both gas (1) and diagenesis (2) analyses are performed within the frame of an ongoing project. These two PhD studies are found by BRIDGE-Programme (FFG) between the Department of Petroleum Geology and RAG.
Within my PhD project, I investigate Upper Visean black shales (“Rudov Beds”)of the Ukrainian Dniepr-Donets Basin (DDB) regarding their potential as a petroleum source rock. Work performed until now focused on two aspects, (1) Rudov Beds as a potential source for hydrocarbons trapped in conventional reservoirs and (2) their relevance as a target for unconventional (shale oil/gas) production. Both aspects need to be approached in a different way.
