Predicting ground deformation due to CO2 injection: Examples from Montmiral, France, Sleipner, Norway and Florina, Greece
conference paper
This chapter describes the use of integrated geomechanical numerical modeling for the assessment of induced geological hazards related to CO2 sequestration. Production of subsurface mineral resources and geological disposal of energy residues including CO2 may induce anthropogenic geological hazards, such as land subsidence and triggered earthquakes. For public acceptance of geological sequestration of CO2, it is important to evaluate the induced geohazards and assess risks they pose to the leakage of CO2 and to the environment. The mechanical effects of CO2 injection and associated ground deformation are predicted for the assumed CO2 injection into three selected sites. Two of the modeled sites represent natural accumulations of CO2—Montmiral; France; and Florina, Greece, while the third site is an offshore hydrocarbon field—Sleipner, Norway. These sites are studied in the framework of the European Union (EU) research project “Natural Analogues for the storage of CO2 in the Geological Environment” (NASCENT). The objectives of geomechanical modeling are to assess the impact of CO2 injection on the mechanical integrity of reservoir rock and caprock, the stability of existing faults and ground deformation. The outcomes of the modeling studies are dependent on several site-specific geological, geomechanical, and reservoir parameters.
