The approach to modeling geomechanical processes in the well vicinity including mathematical modelling of deformation, fracture and filtration as well as experimental determining the parameters involved, under conditions, corresponding to the real in situ ones is presented. The approach involves three stages: (i) choosing the mechanical model and its adopting to the considered problem; (ii) determining the model parameters by using the direct experiments; (iii) mathematical modeling of deformation, fracture and filtration processes in question.

The important mechanical model feature is that it accounts for anisotropy of mechanical and filtration properties and dependence of yield transition on volumetric stresses and pore pressure. Another important peculiarity consists in using the experimentally determined dependences of permeability on stress-strain state.

The results of the experimental determination of the model parameters for two lithotypes of Kirinsky field and one lithotype of Filanovsky field using the Triaxial Independent Loading Test System (TILTS) are given. Numerical simulation for the used model for the cases of uncased and perforated bottomhole is presented. The stress concentrations and production rate are calculated. The results of the work carried out demonstrate the capability of the approach to solve geomechanical problems in order to optimize technological processes.
