In a context of global climate change, reduction of greenhouse gas emission, and optimization of the energy resources, the use of underground for either store or extract energy via fluid or mass transfer (gas, water, heat) is reaching a stage for deployment of pilot or commercial scale sites. For each country, the national regulation for such implantation requires very often a model-based assessment (via specific guidelines) to evaluate different stages of the power plants implantation: feasibility and design of the site, prediction and optimization of the injection-production-storage process, environmental impacts and risk assessment, and post-closure and long term evolution of the site and surrounding areas.

We propose in this session to discuss about the modeling capacities and performances to provide such insights looking at three specific applications:

  • CO2 geological storage,
  • Geothermal production, and
  • Managed Aquifer Recharge.

Building up a calibrated model takes up time and requires a detailed data set, however, modeling does not always lead to success. Proposed papers should illustrate how, once confronted to the field data, modeling is capable to manage and provide acceptable estimations of the field sites evolution at all stages and what are the actual limitations and progress to consider.

Specific simulated processes include but are not limited to:

  • Field case study of fluid or heat flow injection/production in porous and/or fractured media
  • Two phase flow modeling (unsaturated zone, gas-liquid flow)
  • Saline fluids transport (reservoir brines flow, saltwater intrusion, buoyancy induced flow)
  • Clogging phenomenon related to field activity (wells, aquifers reservoirs porosity)
  • Hydro-geochemical environmental impacts (water quality, microbial activity, elements release)
