Inverse Modelling of Geretsried Eavor-Loop Production Data

[Eavor, Canada]
The construction of the world’s first commercial Eavor-Loop™ project is ongoing at the Eavor-Europe™ site in Geretsried, Bavaria, Germany. The Eavor-Loop™ is a multilateral closed-loop geothermal system where a working fluid circulates through an underground heat exchanger to harvest thermal energy from a subsurface reservoir. Eavor-Europe™ is a combined heat and power geothermal project, which will supply the surrounding region with district heating and electricity. The project is expected to produce 64 MWth of thermal power, or 8.2 MWe of electricity generation, once all four Eavor-Loops™ are completed. An inverse modelling approach is applied to early-stage production data from the first Eavor-Loop™ at Geretsried. A history matching exercise is used to train a transient thermodynamics and heat transfer model, thereby reducing the uncertainty in subsurface parameters that govern loop performance. A probabilistic forecast produced by the trained model is compared against measured performance, illustrating the predictability of closed-loop geothermal systems.
