Time-Dependent Hydro-Geomechanical Reservoir Simulation of Field Production

In this paper pore pressure effects such as stress reorientation and faults reactivation are considered. Risk assessment of these effects is crucial for field development planning. Coupled 4D hydro-mechanical modelling was carried out to evaluate the prospects of well-candidates for repeated multistage hydraulic fracturing, particularly the repeated fracture geometry alteration. Furthermore, the factors influencing repeated fracture orientation were clarified. Influence of pore pressure on faults reactivation was considered in the context of fault permeability definition. Several methods for validation of numerical simulations have been reviewed.
