WP 2: Digital Geothermal Reservoir Twin
Building upon the enhanced data streams from WP1 and other measured sources of data, e.g., of rock physical properties, in this WP, we construct the digital twin of a geothermal reservoir. This will enable physical interpretation of reservoir evolution at early stages (e.g., during stimulation) and late times of operation of the system. Simulations would include synthesis of seismic waveform data and forward and inverse Uncertainty Quantification (UQ) to allow the assessment of the performance of the model’s components in structured pseudo-prospective and fully prospective validation tests.
