Authors: Yu.A. Kashnikov, S.G. Ashikhmin, A.E. Kuchtinski, V.E. Vildeman, M.P. Tretyakov, P.S. Bazhukov (Perm National Research Polytechnic University, RF, Perm)

Key words: hydraulic fracture, rocks, core, fracture toughness.

The results of determination of fracture toughnesscoefficients for rocks of oilfields LUKOIL-Perm LLC are presented. The results of core testing can be used for hydraulic fracture design purposes. The necessity of standardized method for determining the characteristics of the fracture toughness of rocks was shown.
