Scattered waves detection of fractured zones in the high salinity waters dolomite layers of the Lower Cambrian saliferous-carbonaceous complex which are characterized by higher than normal formation pressures. When hole boring in the fractured zones, catastrophic drilling mud absorption, gas ingress, casing columns crush in some wells are observed. Identification of such zones when designing and building wells will allow avoiding complications and damages while drilling.
