Validation of model for fluid migration against field-site data

Predictions made from the fluid migration models are tested and validated against micro-seismic and hydraulic data. The models will be adjusted as appropriate to fit the field-site data. Geomecon : geomecon will employ a software package based on the eXtended FEM (XFEM), i.e., roxolTM to simulate the propagation, initiation and reactivation of fractures; the software offers the unique possibility to understand the fracturing process during hydraulic fracturing campaigns applied in the extraction of unconventional oil and gas, which will enable the safe deployment of geo-energy operations in Europe. Within S4CE the software package will be calibrate against the existing well characterised data set from St. Gallen inclusive of data before, during and after gas production to gain further insight into the observed induced seismicity and allow explicit models of fracture propagation and fluid transport in sub-surface formations. These models are than implemented into large-scale fully coupled thermal-hydro-mechanical simulations using COMSOL Multiphysics, a finite element code, on the St Gallen data set to evaluate whether poroelastic effects or fast fluid flow along fractures caused the induced seismicity in St Gallen.
