A newly installed research infrastructure for geothermal energy in a subsurface sedimentary reservoir for direct-use heating: The TU Delft campus geothermal project

A geothermal doublet has been installed in a sedimentary reservoir for direct-use heating on the TU Delft campus, targeted to supply around 25 MW of thermal energy at peak conditions. This contribution presents the implementation and initial data collection from the doublet, including an initial evaluation of the logging and coring campaign....

Refine Conceptual Models in A High Enthalpy Geothermal Field

The primary goal of this study is to build new and integrated conceptual models for a high temperature field in Indonesia. Providing new data, combining models, visualizing them in 3D is significant to refine previous 2D traditional models, which are limited for reservoir characterization and wellplacement. During field utilization, constantly...

Clogging mechanisms in geothermal operations: a case-study of a geothermal field in the Netherlands

The number of geothermal operations worldwide has been actively growing over the last decades. To increase their efficiency, prevent reservoir depletion and avoid environmental issues, produced water is commonly reinjected. Despite these benefits of fluid reinjection, various clogging problems resulting in injectivity decline have been reported...
