Petroleum Production Systems

• Since July 2024: Research Assistant at ITE, Clausthal University of Technology,

Geothermal and Natural Gas Drilling Technology

Investigation of the flow and phase equilibrium behavior of formation fluids, with a particular focus on determining the key parameters for salt precipitation. Analysis of thermodynamic and chemical factors influencing CO₂ solubility in geothermal and gas-bearing brines.

Concurrently, optimization of drilling fluids with regard to rheological properties, filtration control, and chemical stability to increase drilling process efficiency, minimize swelling of clay-bearing formations, and maintain wellbore integrity under geothermal and high-temperature conditions.

• Since January 2023: Research Assistant at IMVT, Clausthal University of Technology,

Development of innovative products with a focus on the production of nanostructured metal oxide materials such as Fe₂O₃, SiO₂, MnOₓ, and TiO₂. This involves comprehensive characterization as well as the systematic development and optimization of manufacturing processes. Analytical methods enable targeted improvements in the structure, composition, and properties of the nanomaterials.
