Modeling Deformation and Failure of Anisotropic Rocks nearby a Horizontal Well

Abstract

The article describes modeling mechanical behavior of rocks, including selection of models of inelastic deformation process in anisotropic rocks, experimental determination of elastoplastic properties of rocks and calculation of stress states for specific design well bottoms. The research is carried out for the conditions of Fedorov oil reservoir. The scope of modeling embraces the situations of uncased well shaft and shaft with slotted holing.
