Reservoir Engineering
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).

Decarbonization and Energy Transitioning
The Intergovernmental Panel on Climate Change (IPCC, WG III, 2014) presents a series of energy and climate scenarios covering potential future pathways ranging from “very optimistic” to “business as usual,” including all the consequences for the environment and society. Even in the most favorable scenario (RCP 2.6) that allows mankind to maintain global warming below 2 °C, it is predicted that at the end of the 21st century, the total energy consumption will be higher than today with more than 50 % of fossil fuels in the primary energy mix. Among other measures, this scenario requires a wise selection of the fossil fuel types being developed in view of energy efficiency and the CO2 footprint of hydrocarbon production. Furthermore, a wide application of carbon capture and storage (CCS) will be required to mitigate greenhouse gas emissions associated with fossil fuel combustion and production.
The Chair of Reservoir Engineering is contributing to creating a sustainable energy future with research that may be categorized by: (a) subsurface hydrogen storage and conversion for large-scale renewable energy storage, (b) decarbonization by geological CO2 storage, and (c) understanding energy transitioning by arts-based research.
Digitalization
Reservoir engineering has long been digital. With today's computing power, it is possible to run simulations to significantly reduce and capture uncertainties that go beyond previous capabilities. This project is based on the implementation of new technologies from the pore to the field scale.
With the help of Digital Rock Physics (DRP), multiphase-flow parameters are being simulated that would otherwise need to be measured with great effort on a selected sample set that may not be statistically representative. DRP also allows multiphase flow to be directly simulated on digital twins from the m-CT (micro computed tomography) images, and highly complex geological models can be equipped with the results. Uncertainties can systematically be addressed, which paves the way for stochastic reservoir modeling and puts corresponding predictions in a correct statistical light. Moreover, the project is striving for a consistent integration of parameters from digital rock physics and special core analysis in a stochastic reservoir modeling workflow.
Enhanced Recovery
A major part of the conventional oil reserves cannot be recovered by primary and secondary recovery methods. This unrecovered oil is the target of Enhanced Oil Recovery methods (EOR) that have been developed to extract more oil from mature fields and enhancing recovery. However, EOR is typically expensive and is applied at a 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), to be able to develop cost-competitive 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.
In addition to developments in the Vienna Basin, fracture-carbonate fields in the Middle East are prospective targets of the chair. There are two ongoing projects that deal with two major fields in the region. Technologies related to the exploration, production, and improving recovery from carbonate reservoirs are screened and developed. The main emphasis is on optimizing tertiary recovery by considering different EOR mechanisms in reservoir simulations and laboratory measurements. Based on field data, the project delivers the necessary elements for the design of EOR pilots.

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.
