The Cretaceous basins within the Central Africa Rift sub-system (CAS) share similar tectonic processes, histories, and styles of basin fill, raising the question of the extent to which oil and gas generation is synchronised across the West and Central African Rift System (WCARS). Basin modelling was used to calculate the amount of hydrocarbons generated, the development of sealing capacity and losses of petroleum to the surface for the Melut, Fula, Sufyan, Bagarra, Doseo, and Doba rift basins. It was found that critical periods of hydrocarbon generation within the CAS occurred in the Lower Cretaceous, Upper Cretaceous and Paleocene-Eocene. During the Lower Cretaceous, regional seals had yet to be deposited, while during the Upper Cretaceous and Paleocene-Eocene, seals were poorly compacted and likely still did not constitute a good seal. During these intervals of time, high volumes of petroleum left the petroleum system (e.g. seeped to the surface). The resultant rates of methane seepage for the CAS rift-basins was 10¹–10⁵ tons/year and is both quantitatively significant, and comparable to similar basins and rift systems. This rate of seepage is sufficiently high as to imply that micro-seepage alone would not have been capable of releasing the methane and that at least some seepage would have been catastrophic.

中非裂谷子系统 (CAS) 内的白垩纪盆地具有相似的构造过程、历史和盆地充填方式，提出了西部和中非裂谷系统的油气生成同步程度的问题。 WCARS）。盆地建模用于计算 Melut、Fula、Sufyan、Bagarra、Doseo 和 Doba 裂谷盆地的油气生成量、密封能力的发展和石油向地表的损失。研究表明，中科院内生烃关键期发生在下白垩统、上白垩统和古新世-始新世。在下白垩统期间，区域性密封尚未沉积，而在上白垩统和古新世-始新世期间，密封性较差，可能仍未构成良好的密封。在这些时间间隔内，大量石油离开石油系统（例如渗入地表）。合成的 CAS 裂谷盆地的甲烷渗流率为 10^{1 –} 10 ⁵吨/年，并且在数量上都很重要，并且与类似的盆地和裂谷系统相当。这种渗漏率足够高，意味着单独的微渗漏不能释放甲烷，并且至少有一些渗漏会是灾难性的。
