摘要

The Upper Cretaceous sequence is among the most productive petroleum-bearing intervals in Egypt, supplying significant hydrocarbon reserves in several basins. In this editorial, its significance is emphasized through two case studies of rift-related basins; the Gulf of Suez Basin and the Abu Gharadig Basin. For the Gulf of Suez Basin, the Matulla, Abu Qada, Wata, and Raha formations present heterogeneous clastic reservoirs with irregular productivity. In the Abu Gharadig Basin, the Bahariya and Abu Roash formations (Members C-G) hold a prolific portfolio of conventional and unconventional plays, governed by facies control, diagenesis, and fracture systems. Direct comparison indicates that while the Gulf of Suez Basin offers more predictable sandstone reservoirs, the Abu Gharadig Basin offers a wider but more complex hydrocarbon system. Collectively, these reservoirs identify the Upper Cretaceous as a keystone of hydrocarbon riches in Egypt and underscore the use of integrated geophysical, petrophysical, and reservoir modeling tools.
