Finite-element modelling of stress development and fault reactivation in and around a producing gas reservoir: quantification of calculation results in DIANA

Stress changes related to the depletion of gas reservoirs in the northern Netherlands can lead to small seismic events. Field data analysis makes it very likely that these events are the result of reactivation of existing faults or joints in or near the reservoirs. DIANA is used to model 3D gas reservoirs, in order to analyse stress development...
