Abstract

Abstract:

The Bangor Basin,a Meso-Cenozoic rift basin developed under the influence of the West and Central Africa Rift Systems,is located in the joint of the West Africa Rift System and the Central Africa Rift System.The basic geological conditions in the Bongor Basin are favorable for hydrocarbon pooling,including multiple sets of quality source rocks in the Lower Cretaceous,multiple sets of sandbodies with good reservoir properties,effective traps,3 quality regional seals and excellent source-reservoir-seal combinations.The structural traps and the structural-lithologic traps are predominant.The distribution of hydrocarbons is under the control of the distribution of hydrocarbon kitchen and mature source rocks,regional seals,reservoir sandbodies and secondary structu-ral zones.For further exploration,the focus will be the middle section of the northern slope zone,pre-Mesozoic basement,east and west sides of the northern slope zone and the southern steep slope zone.

Key words: source rock, reservoir, hydrocarbon pooling, Bongor Basin, West Africa Rift System
