Achieving a sustainable energy future is a major present-day challenge in which fossil fuels are predicted to play a dominant role over decades. In order to address a sustainable energy supply, developments and targets in the areas of renewable energies and fossil fuels must be coupled and balanced.
Reservoir Engineering is a key discipline to drive advances in subsurface technologies in order to improve the balance between energy production and environment impact through R&D.
In this context, the Reservoir Engineering Group aims to provide best possible education, to further develop the field of reservoir engineering and to tackle the energy-supply challenge and related topics by cooperating with the public sector and energy companies. We focus on economically feasible and environmentally friendly hydrocarbon recovery methods, gas injection for energy storage (power-to-gas) and sequestration (CCS).
Engineering future energy!
Due to the growing global demand for energy and the relatively slow transition to sustainable energy sources, the combustion of carbon-based fuels will remain the world’s major energy source for the coming decades. In order to achieve climate targets, transition technologies are required to reduce CO2 emissions during this period. Carbon Capture and Storage (CCS) is such a technology with a high potential to reduce greenhouse-gas emissions, and potentially even achieve a negative CO2 footprint. Research in the area of subsurface storage is typically focused on storage capacity and storage safety.
In this context, a currently ongoing PhD project is focused on the coupling of flow and geomechanics. The final goal is to model CO2 injection in fractured reservoirs with pre-existing faults and to estimate the effect of mechanics on flow and on storage capacity as well as estimating the risk of leakage and fault activation.
Despite the challenges and ongoing R&D, current knowledge and capabilities are sufficient to already identify safe subsurface containers in which CO2 can safely be stored. In particular, depleted gas fields and sandstone reservoirs are promising candidates for storage operations. But even in such cases, an elaborate effort of reservoir characterization and reservoir engineering is needed to guarantee safe storage and to optimize injection performance and storage capacity. Further R&D is focused on carbonate reservoirs. Those are more complex due to their multi-scale structural heterogeneities. Also the high reaction rate of carbonates with carbonic acid raises some challenges for predictive reservoir modeling and is hence a rich playground for research.
Geological Hydrogen Storage
Hydrogen is a very valuable source of energy. It can be produced from – e.g. – a surplus of renewable energy production or from heavy-oil production through upgrading. However, the production of large amounts of hydrogen needs the respective storage capacity to meet the demand. This is what we are working on.
The Reservoir Engineering group participates in a pilot project assessing the feasibility of large-scale hydrogen storage in a former gas field in Upper Austria (which should not be confused with – e.g. – the more developed small-scale hydrogen storage devices for – e.g. – transport applications). The target is the temporary surplus of wind and solar energy, which demands for storage capacity in order to cover for seasonal fluctuations of renewable energy production (www.underground-sun-storage.at).
We work on the chemical interaction between the injected hydrogen, the formation rock and the fluids in place. The target is to predict the stability of hydrogen in the reservoir as compared to the intended time scale of storage, which defines the purity and the value of the back-produced gas.
Improved and Enhanced Oil Recovery
A major part of the conventional oil reserves cannot be recovered by primary and secondary recovery methods. Tertiary processes or Enhanced Oil Recovery methods (EOR) have been developed to extract more oil from mature fields and enhancing recovery. However, EOR is typically expensive and is applied at high oil price.
Our aim is to establish the necessary numerical and experimental tools to better understand EOR processes on multiple scales (pore to field) in order to be able to develop low-cost options tailored to individual fields. The focus areas will be on water-based techniques such as alkaline and low-salinity water flooding and on CO2 EOR.
Upscaling of Porous Media Flow
Our primary research interest relates to multiphase flow in complex rock such as multi-porosity and fractured carbonates. Thereby we place emphasis on flow processes that dynamically change rock and fluid properties – i.e. reactive transport, wettability alteration, etc. – and their feedback to flow mechanisms. We aim to address these mechanisms on their natural length and time scales by state-of-the-art laboratory experiments, numerical interpretation and upscaling to the field-relevant scales.

Improved Oil Recovery (IOR), Enhanced Oil Recovery (EOR), Reservoir Modelling & Simulation, and Wax & Asphaltene studies.
Numerous production mechanisms and harsh reservoir conditions make the available EOR and most chemicals used for conventional reservoirs not to be suitable for naturally carbonated fractured reservoirs. Hence better reservoir characterization and proper selection and design of the injection fluids requires more attention. In my research, I was able to visualize and identify these mechanisms through designed experimental and modeling techniques. Processes such as GAGD, VAPEX, SAGD, TAGD, etc. were investigated thoroughly with the main focusing on understanding and quantifying EOR mechanisms for NCFR.
