Taking 3D seismic survey in Melut Basin for an example, we study the types and hydrocarbon accumulation model of subtle prospects in the slope zone controlled by palaeohigh in passive rift basin. Based on palaeogeomorpholgy restoration and sedimentary facies study, the subtle prospects contain the types of stratigraphic overlap and lithologic pinch-out in the zone, which mainly develop in the strong rift phase. The stratigraphic overlapping boundary can be identified by seismic attributes of Number of Zero Crossings, and the slump fans can be identified by seismic attributes associated with amplitude energy.
