Simulator (Voskov et al., 2023) is a simulation framework for forward and inverse modelling uncertainty quantification of multi-physics processes in geo-engineering applications such as geothermal, CO2 sequestration, water pumping, hydrogen storage.To efficiently achieve high levels accuracy on complex geometries, it utilizes advanced numerical methods fully implicit thermo-hydro-mechanical-chemical (THMC) formulation, highly flexible finite-volume spatial approximation operator-based...
Abstract The effective management of geo-energy systems heavily relies on robust modeling frameworks that integrate diverse simulation capabilities, including flow and transport, phase equilibrium, geochemistry geomechanics. While a multiphysics engine within unified framework has its advantages, integrating specialized packages often enhances viability. Efficient seamless communication between these engines be- comes crucial for improving the performance scalability integration. Advanced...

<title>Abstract</title> Pore pressure fluctuation in subsurface reservoirs and its resulting mechanical response can cause fault reactivation. Numerical simulation of such induced seismicity is important to develop reliable seismic hazard risk assessments. However, modeling reactivation quite challenging, especially the case displaced faults, i.e., faults with non-zero offset. In this paper, we perform a systematic benchmarking study validate two recently developed numerical methods for slip...
