Renewable Energy, 2022
We explore an enhanced geothermal system (EGS) reservoir with horizontal wells connecting multiple hydraulic fractures. In particular we follow the implications of complex thermal – hydraulic – mechanical on the thermal unloading of rock matrix on the ...

Challenges for Numerical Modeling of Enhanced Geothermal Systems
Groundwater, 2010A recent guest editorial by Wood (2009) pointed out the potential of enhanced geothermal systems (EGS) as a future source of “green” energy and suggested that EGS offers research opportunities for hydrogeologists seeking to become involved in the world’s energy future.

Enhanced geothermal systems (EGS): A review
Renewable and Sustainable Energy Reviews, 2016Abstract Geothermal energy is a renewable energy source that can be found in abundance on our planet. Only a small fraction of it is currently converted to electrical power, though in recent years installed geothermal capacity has increased considerably all over the world.
