Stratigraphy comments: Definition. The top of this zone is indicated by the last
occurrence of Pilosisporites trichopapillosus and the occurrence of Afropollis zonatus, Leptolepidites psarosus, Concavissimisporites punctatus, Araucariacites australis, Cicatricosisporites spp. and Classopollis spp. Afropollis cf. operculatus and Concavissimisporites cf. variverrucatus are recorded from equivalent strata of the second study well, Khx-1. |
Lithology and environment
Primary lithology: | lithified siltstone |
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). | |
Environment: | fluvial-lacustrine indet. |
