The preliminary studies on the lithostragraphy and depositional environment of the oil shale deposits of the Abakaliki fold belt indicated that three lithostratigraphic units, namely: Abakaliki, Eze-Aku and Awgu shales of Albian to Coniacian ages are present.
The Albian to Coniacian sediments have not been adequately studied except on ammonite zonations, lithostratigraphy and organic geochemistry.
Before the Santonian, the Abakaliki region was one of the most important depocentres in the lower Benue Trough with marine sediments, ranging in age from Albian to Coniacian, which were deposited in the proximity of the proto-Gulf of Guinea [17].
A total of thirty-five benthonic foraminiferal species, belonging to twenty-eight genera were recorded from the Albian to Coniacian exposed sections in the study area (Tables 5 and 6).
Most of these species have been assumed to be of the Upper Albian to Middle Coniacian in age [6, 34-36].
On April 7, 2007, began work-over operations on well HEK-3, an oil and gas discovery well drilled by Sonatrach in 2004 when it tested the Cretaceous, Coniacian limestone interval and achieved a flow of 184 barrels of oil over a four-hour period before that was suspended.
This biozone corresponds to Hattin's (1982) lithostratigraphic Marker Units 1, 2 and 3, which are collectively Late Coniacian in age.
