Internal Cycle of Seminars at IMEDEA (CISI) consist on a cycle of seminar presentations given mainly by doctoral students, masters and junior postdocs, although it is not closed to other staff, such as visitors and staff, that take place every Friday from 12:00 p.m. to 12:30 p.m in the seminar room os IMEDEA.
This represents a great opportunity to learn more about the research carried out at the Institute and to bring those with less experience , the chance of increasing their presentation and public speaking skills. Afterwards, there will be coffee and some biscuits 😉 We strongly encourage you to participate. Join us!

Abstract
Geothermal energy is a relevant building block for an environmentally friendly energy economy. The energy is obtained by using hot Groundwater from the (deep) underground of our earth's subsurface. One major challenge for the widespread use of this technology is the characterization of suitable geothermal reservoirs where energy can be extracted.
To address this challenge, we create models that simulate how water flows through underground reservoirs. These models are calibrated with pumping tests from different boreholes. However, drilling testing boreholes is very expensive, which results in a limited of data points for a reservoir model.
Next to traditional physical models, the recently emerging Physics Informed Neural Networks (PINN) offer a promising solution. They incorporate field data while enforcing the accordance with physical laws in the domain of study. Our current results show that our PINN model can forecast the evolution of fluid pressure over space for a heterogeneous rock formation.
