Abstract
The Red Sea rift marks the break-up of the Afro-Arabian plate in the Eocene-Oligocene time. Generally, fluvio-deltaic and marginal to fully marine sediments were deposited, good reservoir quality and potential source rocks are present. To date, the Sudanese Red Sea, like the Red Sea as whole, represents a grossly under-explored petroliferous basin. The pre-Salt Rudeis-Kareem shales are expected to be a good petroleum source rock for the basin. Moreover, Shales of base Zeit (post-Salt) are considered the main source of the known accumulated hydrocarbon (gas and condensate) in the shallow targets. The measured amount of TOC, HI, and hydrocarbon expelled from pyrolysis of kerogen of the examined samples indicates the source rock generative potential of these intervals. The salt tectonic challenging exploration activities and control the hydrocarbon entrapment as well the Salt movement is recent as the recent sediments been deposited and conslidated. In this study,1D and 2D petroleum system modeling has shown that the two source bed are thermally mature for hydrocarbon generation with Rudies Formation exceeded oil window and all its potential transformed to hydrocarbon.
