Key words: hydrodynamic modeling, well testing.
One of the most urgent tasks in the verifying reservoir properties is to determine the structure of arrays of carbonate fractured or cavernous fractured zones. Such reservoir carry both positive and negative features: high flow rates with rapid flooding (if production well reveals the fractured zone) and rather low flow rate values with a low coefficient of reduction (if the well reveals the "matrix" part). However, to control the development of such reservoirs requires detailed geological and hydrodynamic model, which takes into account not only the presence of inhomogeneities, but also changes in their properties for real values of depression and repression.
