We recently published a study exploring how control theory can be used to optimize hydraulic stimulation while mitigating induced seismicity in geothermal systems using a single-well. Using a robust control we show how injection schedules can be adapted in real-time to increase reservoir stimulation efficiency while keeping seismic risk within regulatory limits.
The framework is demonstrated on the 2018 Otaniemi geothermal project, highlighting how control can outperform traditional traffic-light approaches in both safety and performance.

We recently published a study introducing a POD–TANN framework for multiscale modeling in geomechanics. By combining Proper Orthogonal Decomposition with thermodynamics-based neural networks, the approach enables accurate, energetically consistent macroscopic models directly derived from high-fidelity simulations, with a strong reduction in computational cost.

Traditional time integrators struggle with nonsmooth systems, often slowing down or losing accuracy. Our new approach uses Reinforcement Learning to automatically choose optimal time steps, adapting even when the dynamics are nonsmooth. Tested on three challenging problems, a sliding-mode control system, a diode circuit, and a seismic fault model, our RL-based integrator significant speed-ups, reaching up to 10× faster in the hardest cases. A promising new direction for efficient time integration across complex dynamical systems.
