Abstract

In this study subsidence and burial history analysis of Chad Basin Nigeria were reconstructed from 23 deep exploratory well logs. The oceanic lithospheric cooling concept was used for the basin subsidence while the sedimentation history in the basin was reconstructed utilizing the method of “back-stripping” at different locations. All these are aimed at explaining the tectonic origin and evolution of the basin. Subsidence and sedimentation were observed to have occurred mostly in the Albian to Maastrichtian times. The result also shows that the prediction of the simple cooling model, that tectonic subsidence and square root of the age are linearly related, is applicable to the Nigerian Chad Basin. The formation of the basin is associated with rifting and break-up of the African and South American plates. The reconstructed subsidence and burial history of sediments in Chad Basin has provided an insight to the level of maturation of the organic matter contained in the sediments.
