mass that describe stress deformation failure processes of reservoirs under loading modes mechanical properties of rock masses mechanical properties of fractures fluid mechanical interaction parameters and thermal mechanical coupling parameters at 350 a reservoir model is determined the reservoir model is based on the dfn for example the reservoir model can be the example reservoir model 232 the reservoir model is configured to receive the dfn and estimate an amount of hydrocarbon production that the rock formation 42 can provide based on the dfn at 360 a hydrocarbon production volume is determined the hydrocarbon production volume is an estimate based on the amounts of hydrocarbon production estimated by the geomechanical model and the reservoir model for the given first value in some implementations the hydrocarbon production volume can be the example estimated production value 240 in some implementations the reservoir model can be configured to predict the evolution of multiphase flow and pressure fields in the reservoir based on one or more of reservoir pressure distribution parameters reservoir temperature distribution parameters multiphase flow models for fluid flow in rock multiphase flow models for fluid flow in the dfn thermal conduction models thermal convection models porosity parameters permeability parameters saturation parameters thermal conduction property parameters thermal convection property parameters well location parameters well drawdown plan parameters and well temperature parameters at 370 the first value is adjusted based on the determined hydrocarbon production volume in some implementations the first value can be adjusted by the example adjustment module 250 for example the first value can be raised or lowered to.
