Geoenergy Production Engineering
The chair is recognized as a leading center for education, training and research in geoenergy production 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.

Artificial Lift Systems
Artificial lift systems play a significant role in the recovery of oil, gas, and geothermal fluid. The change in reservoir conditions and techniques applied to increase the fluid recovery, alter the produced fluid properties, and challenge the artificial lift systems. The chair is specialized in testing and improving artificial lift systems for the complete range of its application. Simulations, like computational fluid dynamics analysis and finite element analysis, are applied to evaluate the overall performance and improvement of the systems. Mechanical and operational optimizations of the artificial lift systems are studied.
The chair’s pump test facility allows testing artificial lift systems at almost real field conditions and fills the gap between simulations and field tests. The pump test facility allows low testing costs in a controlled environment before expensive field testing is performed.
Coupled Processes Simulation
Geological media are a strategic resource for the forthcoming energy transition and constitute an essential ally in the fight to mitigate the adverse effects of climate change. Several energy and environmental processes in the subsurface involve multi-physical interactions between the porous and fractured rock and the fluids filling the voids: changes in pore pressure and temperature, rock deformation, and chemical reactions coincide and impact each other. This characteristic has profound implications for energy production and waste storage. Forecasts are bounded to the adequate understanding of field data associated with thermo-hydro-mechanical-chemical (THMC) processes. Predictive capabilities heavily rely on the quality of the integration between the input data (laboratory and field evidence) and the mathematical models describing the evolution of the multi-physical systems.
Our chair is dedicated to studies investigating THMC problems, mainly utilizing analytical and numerical methods with applications of carbon capture and storage (CCS), geothermal systems, energy storage, fluid injection-induced seismicity, and radioactive waste storage.
Geomechanics
Geomechanics used to be a branch of geoscience that interests primarily drilling and completions engineers. However, with the advent of unconventional resource development, geomechanics now touches almost every aspect of geo-energy exploration and production activities from well completions to reservoir management (subsidence or induced seismicity). Beyond geo-energy applications, geomechanical integrity is a crucial component in the operation design for underground energy storage, CO2 sequestration, or nuclear waste disposal.
We look into subsurface stress estimates and its evolution associated with anthropologic pore-pressure or temperature changes. Apart from application importance, our chair is very fascinated by the scientifical challenges in the area of fracture mechanics.
Geothermal Energy Recovery
Geothermal energy is an inexhaustible source of primary energy, spread globally and in massive amounts worldwide. The recovery of geothermal energy requires only small footprint facilities, and its extraction is known to be CO2 neutral and waste-free. To reach the defined emission limits, a considerable effort will be spent in the early future. A key technology will be to recover geothermal energy from small to large scale, as it provided besides other ground load potential.
The chair concentrates on steady-state and transient heat flow simulations for the conditions in- and outside of the geothermal well. Besides, the investigation of alternative materials for improving the operability of geothermal wells is done.
Simulation and Production Data Management
We are living in the era of data and we must learn how to capitalize its meaning. In Petroleum Production Engineering we are focusing on developing tools based on gigabytes of production data received daily in order to reduce operating costs and risks, increase production rates, contribute to faster and better decision making processes, reduce emissions, all these in order to lead to a more sustainable industry.
Our Chair has already been successful in this area during tight collaborations with several operating companies by building well monitoring and failure prediction tools for artificial lift systems. The outcome has demonstrated an increased data quality, more efficient production operations and more effective decision support tools.
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.
Well Stimulation
Be it a production or an injection well, many of them require stimulation at some point in their lives. A well could be damaged from drilling or completion operation or builds up formation damage during the course of production or injection. For Enhanced Geothermal System (EGS), well stimulation is a prerequisite for resource development.
We study not only conventional stimulation techniques such as hydraulic fracturing, acidizing, or acid fracturing but also unconventional techniques using ultrasound.
