Abstract

Abstract:

To study the enrichment patterns of oil and gas in Fula depression of Muglad basin, Sudan, the reservoir control factors are studied with analysis theory of basin structure. In Fula depression, Abu Gabra Formation developed in Early Cretaceous is an effective hydrocarbon source rock, and three sets of source-reservoir-cap rock assemblages are also developed, among which Abu Gabra is a favorable assemblage of in-situ source and reservoir, while the second set is composed of source rock in Abu Gabra, channel sandstone reservoir in Bentiu and shale seal in Darfur Group，the third set is characterized by Abu Gabra generating, Darfur Group collecting and sealing; they are all favorable assemblages which have the advantages that the oil and gas migration is controlled by fault，and the distribution by the geological structure background and sand distribution, the enrichment by regional caprock. The central structure belt in Fula depression is the main bonanza pool which is a potential area for oil and gas exploration.

Key words: hydrocarbon enrichment, hydrocarbon exploration, half-horst or horst, effective source rock, Fula depression, Muglad basin
