Currently Active Enhancement Projects

GMG-EP-2 (2020-2022) (funded by Shell): Stress-based seismicity forecasting for CO2 storage.

Experimental plan:
  • WP1:Development of a modeling framework to  estimate pore pressure, reservoir deformation, and  stress variations with uncertainties quantification. Estimate seismicity rate with account for the nucleation process represented using the rate&state formalism.
  • WP2: Evaluation of the forecasting performance using the  Groningen  test case. This task involves the production of a seismicity catalog produced with Machine Learning techniques.

Experimental plan:
  • WP1:Surface deformation measurements.
