Petroleum and Geothermal Energy Recovery
The chair is recognized as a leading center for education, training and research in petroleum production and geothermal engineering with strong ties to a wide range of industries.
We are committed to research programs that meet the requirements of an environmentally conscious and responsible energy recovery including natural gas, petroleum, geothermal energy and other unconventionals. The international and interdisciplinary team of the chair is constantly working on innovative solutions for the future.

Research
Computational Fluid Dynamics (CFD)
For many years, the CFD group has been working on modeling of complex fluid flow and combustion problems. The software development activities are based on the open-source toolbox OpenFOAM and the commercial code FLUENT.
Main research areas include:
- thin film flows as can be found in the cleaning, painting and coating industries,
- multi-physics problems such as fluid/structure interaction in hydrodynamic bearings,
- drilling problems in particular modelling of gas-kick phenomena and
- complex non-isothermal fluid flow networks with focus on turbo-generator cooling.
Geothermal Energy Recovery
A sustainable source, geothermal energy and its recovery remain highly future-proof. We as petroleum engineers want to enhance the energy production from the earth by optimizing and developing new technologies, materials and media.
Sucker Rod Pump Systems
Worldwide, there are approximately 2 million oil wells and 37.5% of them use rod pumps as artificial lift method. Our goal is to optimize operations and develop technologies more efficient and capable to meet future requirements of our industry.
Recent research topics at our chair are:
- acoustical analysis of sucker rod pumps and
- dynamic behavior of the rod string, e.g. buckling prediction.
Ultrasound in Oil and Gas Industry
The ultrasonic technology provides a commercial and environment friendly solution to:
- treat different types of scaling, corrosion and precipitations,
- manipulate fluid viscosity,
- clean cuttings/sand contaminated by oil,
- optimize physical properties of cement and
- kill bacteria and algae in fluid media.
