During the last few decades, due to its high potential for hydrocarbon exploration, the basin has attracted a variety of studies that used a wide range of geological and geophysical methods (Agagu and Adighije, 1983;Cratchley et al, 1984;Benkhelil, 1989;Onwuemesi, 1997;Abbass and Mallam, 2013;Adetona and Abu, 2013;Obiora et al, 2015;Abdullahi and Singh, 2018;Ekwueme et al, 2018;Obasi et al, 2018;Okorie et al, 2019;Oguama et al, 2020).
