In case of carbonated reservoir with bifurcated system of fractures, well productivity depends on fact of fractures penetration and size rock blocks without fractures. Definition parameters of that system are difficult with help of classic filtration model and demand from use not only new interpretation algorithms, but special testing methodic. This paper describes definition algorithm of main parameters of those layer systems, which may be used in development planning and monitoring.
