P604 GEOMECHANICAL MODELLING OF THE INDUCED SEISMICITY FOR A GAS FIELD Abstract 1 Gas production from a reservoir may lead to reactivation of nearby faults which is likely to cause local seismic events. This paper is focusing on the calculations of stress evolution during depletion of a gas reservoir in order to investigate the possibilities for the reactivation and slip on normal faults thrust faults and bedding planes at the contact between reservoir and overburden. The program DIANA was used for finite element calculations for a gas field under consideration. Several calculation were run with various initial stress regimes and
