Smit, Freek (author)Geothermal energy in the Netherlands is growing in general, however, medium deep geothermal (200 - 1500 m depth) is lagging behind while the potential at these depths could be very high. Development is held back by little geologic knowledge of this interval as well as legislative constraints. Better understanding of the reservoir characteristics...master thesis 2022

Barreiros Jorge, Sofia (author)Subsurface energy projects carry high risk due to the lack of data available to accurately model reservoir characteristics. There is a need for high level analysis to extrapolate subsurface data from a single point (i.e. a well). The focus of this study will be on fracture characterisation in a carbonate reservoir located within the Geneva Basin...master thesis 2022

Tripathi, Anushka (author)Global energy transition is crucial in mitigating climate change. Numerous initiatives are being taken globally to achieve a carbon-neutral energy system. These goals require a complete shift from non-renewable energy sources to renewable sources like geothermal energy. These renewable sources of energy have to be constantly improved in order to...bachelor thesis 2022

van de Weijer, Paul (author)Geothermal sources could provide society with clean and renewable energy nearly eternally. Geothermal district heating, in particular, could play a significant role in the energy transition. Although the application has been implemented to some extent, further upscaling is challenging due to various economic, technical and institutional...master thesis 2022
