Abstract: Study of the characteristics of transfer structures and their control of sand bodies is of great significance for lithologic reservoir exploration in steep slope zones of rift basins. This paper analyzes the development position, type, and characteristics of the transfer structures in the western steep slope zone of the Fula sag in the Muglad Basin, Sudan, and their control effect on sand bodies during the rifting period of the steep slope zone. Favorable areas for development are identified and the accumulation model of lithologic oil and gas reservoirs in the western steep slope zone of the Fula sag is described. Analysis is based on restoration of the growth process of the western boundary fault in the sag (the Fula-western fault). Results show that there are four synthetic transfer structures in the Fula-western fault from north to south, which controlled the development of sand bodies in the Abu Gabra Formation in the steep slope zone during the rifting period. The controlling modes of sand body development can be divided into two types: transfer slope mode and transfer fault mode. Three favorable zones for lithologic oil and gas reservoirs are developed in the western steep slope zone of the Fula sag. They are located close to hydrocarbon generation and expulsion centers, in the hanging walls of faults and on the up-dip direction of transverse anticlines related to the transfer structures, which are on favorable pathways for secondary hydrocarbon migration. Different types of oil and gas reservoirs are regularly distributed in different structural positions on the transverse anticlines. Faulted anticline reservoirs can form at the tops of transverse anticlines. In these anticlines, up-dip pinch-out sandstone reservoirs can form in both flanks and fluxoturbidite-lens reservoirs form easily at the bottoms.
