Abstract
The Gongola sub-basin is a frontier inland sedimentary basin which consists of Cretaceous to Tertiary sediments, believed to have been deposited in continental to coastal shallow marine complex. The Kanawa Member of Pindiga Formation is a sequence of limestone and shale. Sedimentology, facies analysis, biostratigraphy, thermal maturity assessment and kerogen typing was conducted on these strata with an objective of determining the paleoenvironment, age, and hydrocarbon potential. The sediments consist of mainly wackestone and packestone facies, shallow marine foraminiferal which suggestthat the Kanawa Member was deposited in coastal-shallow marine setting, preferably ramp facies succession under low-energy condition. the presence of Ammobaculites subcretacea, Haplophragmoides bauchensis, Haplophragmoides pindigensis, Haplophragmoides excavata, Ammobaulites pindigensis, Ammobaculites bauchensis, Ammobaculites gombensis, Ammobaculites benuensis Ammoastuta nigeriana, Reophax guineana and Miliammina pindigensis foraminiferal assemblages, indicating Late Cretaceous age. Hydrocarbon potential is interpreted to be gas prone although, minor oil could be expected. These correspond to temperature range (TAI values) of 60 to 75 indicating thermally matured for both oil and gas generation.
