The role of rock anisotropy in hydraulic fracturing through acoustic emission
Recently, a large variety of different aspects-features of the set-up of the hydraulic fracturing (HF) has been investigated. The texture anisotropy and/or crack anisotropy have a great influence over the effective mechanical properties of rocks and the way of their fracturing and failure. We believe that the influence of texture and/or crack anisotropy, as a characteristic property of most of the rocks, deserves to be studied in greater detail.
