This work presents an AI-driven approach for the sustainable use of subsurface renewable energy resources. By combining reinforcement learning with robust control theory, the framework adapts fluid injection strategies to mitigate human-induced seismicity while satisfying energy production objectives.
Numerical simulations show that this hybrid control–AI strategy can operate reliably under uncertain subsurface conditions and variable energy demand, offering a pathway toward safer and more intelligent geothermal and subsurface energy systems. More coming soon!

We recently published a study proposing a control-theory–based approach to minimize induced seismicity during fluid injection in underground reservoirs used for geothermal energy and subsurface storage. The method relies on a physics-based seismicity model combined with robust tracking control to regulate seismicity rates and fluid pressure while maintaining the fluid circulation required for energy production.
Numerical simulations demonstrate that this approach can safely manage seismic risk under uncertain reservoir conditions and variable energy demand, offering a mathematically grounded alternative to empirical mitigation strategies.

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.
