Residual Gas Geological Storage
It is more than likely that human activity is implicated in global climate warming with a high level of emission of anthropogenic CO2. At the time, in the medium term, it will undoubtedly be difficult to go along without fossil fuel Energy, and industry has to find some ways to decrease the rate of GHG emission, until Clean Energy has taken over.
Geological Storage of CO2 is then considered as a very
attractive way to reach this emission reduction goal. Using the same
geological storage concept for H2S gas, as already applied in
This poster will illustrate the main R&D efforts carried out in order to make a Performance and Risk Assessment on Residual Gas Storages to get public and legal acceptance for these storages. In order to simulate storage reservoir behaviour along 1000 of years, special care has to be taken on Caprock and Wells integrity, to confirm the sustainability of the trap, which requires a lot of improvement of our knowledge and of the necessary modelling tools. Different scientific disciplines as Thermodynamics, Geochemistry, Geomechanics are involved in this process. Another effort has been addressed: investigation on innovative or existing but to be adapted monitoring means for verification and surveillance purpose.
