pdf Modeling the effect of fracture orientation on porus media anisotropy using the T-matrix method
*The article is presented in English.

Fracture orientation is crucial in porous media anisotropy. In the current study we investigate the role of fracture orientation based on a novel Rock Physics method - the T-matrix approach. This method allows us to study the fracture porosity, shape and orientation together with the minerals volumetric and morphological characteristics. In the first part of this paper, we assume that the considered system consists of a set of aligned, penny-shaped fractures. To include the fracture's spatial alignment, we use the Euler angles. The sensitivity of the stiffness components on the main diagonal of the stiffness matrix along the extended Thompson parameters to the fracture orientation change was investigated.
Based on the obtained results we concluded that the effect of fracture orientation on the anisotropy of the system can be explained by introducing a hypothetical qualitative parameter called the fracture projection cross-sectional area on the three perpendicular planes (x1, x2 and x3). We developed three basic rules to describe how fracture alignment controls this hypothetical parameter.

Keywords: аnisotropy, T-matrix method, Euler angles, stiffness matrix, fracture orientation.
