Annotation:

 The data of multi-variant numerical modeling of hydrodynamic well testing (HDWT) at oil fields prove the fact that HDWT data can be used to determine reservoir properties of faults. Unambiguous conclusion, however, is only possible in case of limited number of geometric and methodological parameters combinations of the task. In most cases the description will be ambiguous. But even in such case HDWT data can be successively used but for identification of a such oil field area model which will guarantee minimum of oil recoverability losses arising from uncertainty of field’s reservoir properties structure and non-optimal well development pattern.
