MeProRisk II

Optimization strategies and risk analysis for deep geothermal reservoirs

Status: completed

Description

Geothermal reservoirs provide heat that can be used to generate clean, renewable, and plentiful energy. However, the exploration and the development of these reservoirs involve high engineering and economic risks. Despite steady improvements in drilling technology over the last decades, drilling of numerous deep boreholes from the surface into suitable rock types at a depth of some kilometers is still a major cost component of geothermal energy. The MeProRisk II project aims at reducing these risks by combining skills from different scientific disciplines. Geophysicists, mathematicians, and computer scientists from five German universities and a private company develop and apply new methods in seismic modeling and interpretation, numerical reservoir simulation, estimation of petrophysical parameters, and scientific visualization. The research activities at Friedrich Schiller University Jena include automatic differentiation, parallel computing, and optimal experimental design.
