The strain-stressed state of geology layers induced by one phase filtration is investigated within the quasistationary Biot model. The computational algorithm based on difference schemes of support operator method on the unstructured grids is developed for three- and two- dimensional computer simulation of coupled problem in the formation of complicated structure. The processes are considered for Romashkinskoe production field (Tatarstan, Russia) characterized with the existence of the listric faults. The Mohr-Coulomb failure criterion investigated in the faults demonstrates the possibility of seismic events in domains.
