Lithology and environment
| Primary lithology: | lithified sandstone |
| Lithology description: The successions in several deep wells in the Muglad Basin consist of thick Lower Cretaceous to Paleogene–Neogene strata of claystones, fluvio-lacustrine sandstones and siltstones (Schull 1988). Based on seismic and log interpretations, twelve formations are distinguished in the Muglad Basin of which thick beds of shales and claystones interbedded with fine sandstones and siltstones constitute the Abu Gabra Formation (Neocomian–Aptian), the main source rock in the Muglad Basin. The reservoir rock is the thick sandstone sequence of the Bentiu Formation (Aptian–Cenomanian). | |
