AB  - The potential growth of multiple fractures is investigated during the deformation of the caprock of a reservoir during the subsurface sequestration of CO2. Multiple scenarios of the interaction of pre-existing natural fractures are investigated, as a function of induced stress changes due to the temperature contrast between the injected CO2 and the reservoir. Simulations are performed at the field scale, on a simplified geologically-informed model of the Heletz pilot test site, Israel, in the framework of the EU-sponsored TRUST project. The potential reactivation and growth of pre-existing natural fractures is investigated. During cold injection, changes in the strain field around the well are tracked. The progression of the temperature plume is observed to cause a local release of stresses that in turn causes short propagation episodes, which mostly focus on downward growth. Although some upwards growth is modeled, growth is expected to prominently occur towards the reservoir.
